# Agent Runtime Hooks
Lifecycle hooks for observing and intercepting agent execution. Hooks are registered per-operation via `execAgent({ hooks })` and dispatched by `HookDispatcher`.
## Hook Types
16 hook types across 5 categories:
```
execAgent({ hooks })
│
├─ beforeStep ──────────── Before each step executes
│ │
│ ├─ [call_llm] LLM inference
│ │
│ ├─ [call_tool]
│ │ ├─ beforeToolCall ── Before tool executes (supports mocking)
│ │ ├─ (tool execution)
│ │ ├─ afterToolCall ─── After tool completes (observation only)
│ │ └─ onToolCallError ─ Tool threw an exception
│ │
│ ├─ [request_human_approve]
│ │ ├─ beforeHumanIntervention ── Before agent pauses
│ │ ├─ afterHumanIntervention ─── After approve/reject + resume
│ │ └─ onStopByHumanIntervention ── User rejected, agent halted
│ │
│ ├─ [compress_context]
│ │ ├─ beforeCompact ──── Before compression starts
│ │ ├─ afterCompact ───── After compression completes
│ │ └─ onCompactError ─── Compression failed
│ │
│ ├─ [callAgent] (via execSubAgentTask)
│ │ ├─ beforeCallAgent ── Before sub-agent starts
│ │ ├─ afterCallAgent ─── After sub-agent completes
│ │ └─ onCallAgentError ── Sub-agent failed
│ │
│ └─ afterStep ──────────── After step completes
│
├─ (next step...)
│
├─ onComplete ───────────── Operation reaches terminal state
└─ onError ──────────────── Error during execution
**`onCallAgentError`** — Sub-agent failed. Dispatched on **parent** operation.
```ts
// event: CallAgentErrorHookEvent
{
(operationId,agentId,error);
}
```
Note: CallAgent hooks require `parentOperationId` in `ExecSubAgentTaskParams`.
## Design Notes
- **Fire-and-forget**: All handlers return `Promise<void>`. Errors are non-fatal.
- **Exception**: `beforeToolCall` supports mock via `event.mock()` — uses `dispatchBeforeToolCall()` which returns the mock result.
- **Sequential**: Same-type hooks run in registration order.
- **Local only**: `beforeToolCall` mock only works in local mode (in-memory hooks). Webhook mode does not support mocking.
- **Scoped per operation**: Auto-cleaned via `hookDispatcher.unregister()` on completion.
- **Sandbox/MCP**: No separate hooks — they go through `executeTool`, so `beforeToolCall`/`afterToolCall` cover them. Use `event.identifier` to filter.
## Real-World Example: agent-evals
See `devtools/agent-evals/helpers/runner.ts` — `createEvalHooks()` uses `afterStep`, `onComplete`, `afterToolCall`, and `beforeToolCall` (for mock).
description: Build or extend LobeHub Agent Signal pipelines for background or quiet agent work driven by event sources, semantic signals, and action handlers. Use when adding a new Agent Signal source, signal or action type, policy, middleware handler, workflow handoff, dedupe or scope behavior, or observability around `src/server/services/agentSignal/**`, `packages/agent-signal`, or `packages/observability-otel/src/modules/agent-signal`.
---
# Agent Signal
Use this skill to implement event-driven background work for agents without coupling the work to the foreground chat request.
1. Read `references/architecture.md` to map the package boundary, runtime queue, scope model, and async workflow handoff.
2. Read `references/handlers.md` before writing any new policy, source handler, signal handler, or action handler.
3. Read `references/observability.md` when you need tracing, metrics, debugging, or workflow snapshot visibility.
## Use The Right Entry Point
- Use `emitAgentSignalSourceEvent(...)` when a server-owned producer should execute the pipeline immediately.
- Use `executeAgentSignalSourceEvent(...)` when a worker or controlled backend path already owns execution timing and may inject a runtime guard backend.
- Use `enqueueAgentSignalSourceEvent(...)` when the caller should return quickly and let Upstash Workflow process the event out-of-band.
- Use `emitAgentSignalSourceEventWithStore(...)` for isolated tests or evals that should avoid ambient Redis state.
Read:
-`src/server/services/agentSignal/index.ts`
-`src/server/workflows/agentSignal/index.ts`
-`src/server/workflows/agentSignal/run.ts`
## Core Model
-`source`: A normalized fact that happened. Sources come from producers such as runtime lifecycle events, user messages, or bot ingress.
-`signal`: A semantic interpretation derived from one source or from another signal. Signals express meaning, routing, or policy state.
-`action`: A concrete side effect planned from one signal. Actions do the work.
-`policy`: An installable middleware bundle that registers source, signal, and action handlers.
-`procedure`: Not a distinct runtime node. Treat "procedure" as the end-to-end flow for one use case: ingress source, matching handlers, planned actions, execution result, and observability.
Keep the boundaries strict:
- Add a new `source` when the outside world produced a new event.
- Add a new `signal` when the system needs a reusable semantic interpretation.
- Add a new `action` when the runtime needs a concrete side effect.
- Add or update a `policy` when you are wiring those pieces together.
## Implementation Workflow
1. Decide whether the use case is synchronous or quiet background work.
2. Define or reuse a source type in `src/server/services/agentSignal/sourceTypes.ts`.
3. Define or reuse signal and action types in `src/server/services/agentSignal/policies/types.ts`.
4. Implement handlers with `defineSourceHandler`, `defineSignalHandler`, or `defineActionHandler`.
5. Bundle handlers with `defineAgentSignalHandlers(...)`.
6. Register the policy in `src/server/services/agentSignal/policies/index.ts` and pass it into the runtime factory if needed.
7. Add or update ingress code that emits or enqueues the source event.
8. Add observability and tests before considering the flow complete.
- Reuse existing source, signal, and action types before adding new ones.
- Keep source handlers focused on interpretation and fan-out, not heavy side effects.
- Keep action handlers responsible for side effects, idempotency, and executor-style result reporting.
- Use stable ids and idempotency keys when the same source can arrive more than once.
- Preserve scope discipline. The runtime uses `scopeKey` to serialize related background work.
- Prefer the dedicated shared package types and builders from `@lobechat/agent-signal` for normalized nodes and result contracts.
- Add focused tests near the touched runtime, policy, or store module. Existing tests under `src/server/services/agentSignal/**/__tests__` are the reference pattern.
## References
- Architecture and boundaries: `references/architecture.md`
- Writing handlers and policies: `references/handlers.md`
- Observability, metrics, and debugging: `references/observability.md`
- a trace envelope with source, signals, actions, results, edges, and handler runs
- a compact telemetry record with dominant path, status breakdown, and chain metadata
This projection is built from:
- source node
- emitted signals
- planned actions
- executor results
## How To Inspect A Chain
Use this order:
1. Inspect the source type and payload.
2. Inspect emitted signals.
3. Inspect planned actions.
4. Inspect executor results.
5. Inspect projected edges and dominant path.
The helper `toAgentSignalTraceEvents(...)` flattens a chain into compact event records suitable for tracing snapshots.
## Workflow Snapshot Bridge
Workflow-triggered runs do not naturally pass through the normal foreground runtime snapshot path, so `runAgentSignalWorkflow` adds a development-only bridge into `.agent-tracing/`.
Read:
-`src/server/workflows/agentSignal/run.ts`
Use that path when:
- the source was enqueued with `enqueueAgentSignalSourceEvent(...)`
- you need local trace visibility for quiet background work
## Common Debug Questions
### The source emits but nothing happens
Check:
- feature gate enabled for the user
- source type matches a registered source handler
- dedupe or scope lock did not short-circuit generation

# Agent Tracing CLI Guide
`@lobechat/agent-tracing` is a zero-config local dev tool that records agent execution snapshots to disk and provides a CLI to inspect them.
## How It Works
In `NODE_ENV=development`, `AgentRuntimeService.executeStep()` automatically records each step to `.agent-tracing/` as partial snapshots. When the operation completes, the partial is finalized into a complete `ExecutionSnapshot` JSON file.
**Data flow**: executeStep loop -> build `StepPresentationData` -> write partial snapshot to disk -> on completion, finalize to `.agent-tracing/{timestamp}_{traceId}.json`
**Context engine capture**: In `RuntimeExecutors.ts`, the `call_llm` executor emits a `context_engine_result` event after `serverMessagesEngine()` processes messages. This event carries the full `contextEngineInput` (DB messages, systemRole, model, knowledge, tools, userMemory, etc.) and the processed `output` messages (the final LLM payload).
3.**Final LLM Payload** — Processed messages after context engine (system date injection, user memory, history truncation, etc.), with `[0]`, `[1]`, ... indices. Use `--msg N` to view full content.
## Integration Points
- **Recording**: `src/server/services/agentRuntime/AgentRuntimeService.ts` — in the `executeStep()` method, after building `stepPresentationData`, writes partial snapshot in dev mode
- **Context engine event**: `src/server/modules/AgentRuntime/RuntimeExecutors.ts` — in `call_llm` executor, after `serverMessagesEngine()` returns, emits `context_engine_result` event
- **Store**: `FileSnapshotStore` reads/writes to `.agent-tracing/` relative to `process.cwd()`

# Builtin Tool Authoring Guide
A builtin tool is a package the agent runtime can call. It ships **five faces**:
| Where do files live? What does each face do? Wiring? | [architecture.md](architecture.md) |
| How do I name the tool, design APIs, write the manifest, executor, ExecutionRuntime? | [tool-design.md](tool-design.md) |
| How do I build Inspector / Render / Placeholder / Streaming / Intervention / Portal? | [ui.md](ui.md) |
---
## When to Use This Skill
- Creating a new `packages/builtin-tool-<name>/` package
- Adding a new API method to an existing builtin tool
- Building or restyling any of the 6 client surfaces for a tool
- Wiring a tool into the central registries
- Debugging "tool not found / API not found / render not showing / placeholder stuck" errors
---
## Top-Level Design Principles
1.**`lobe-<domain>` identifier is permanent.** It's stored in message history. Renames need `@deprecated` aliases (see `packages/builtin-tools/src/inspectors.ts:88-89`). Get it right the first time.
2.**ApiName is an `as const` object**, not a TS enum. It doubles as the runtime list `BaseExecutor` iterates over.
3.**Three result fields, three audiences:**
-`content: string` → the LLM reads it
-`state: Record<…>` → the UI's `pluginState`; **result-domain only**, never echo all params back
-`error: { type, message, body? }` → both LLM and UI; `type` is a stable code
4.**Split execution from frontend wiring.**
-`src/ExecutionRuntime/` — pure runtime, no React, no Zustand, accepts services via constructor. **The default place for new logic.**
-`src/client/executor/` — `BaseExecutor` subclass that calls `ExecutionRuntime` (or stores/services directly when frontend-only).
5.**UI defaults to "do nothing".** Inspector is required (the header strip). Render/Placeholder/Streaming/Intervention/Portal are added **only when there's something specific to show** — empty registries are fine.
6.**Style with `createStaticStyles + cssVar.*`** (zero-runtime). Fall back to `createStyles + token` only when you genuinely need runtime values. Use `@lobehub/ui` components, not raw antd.
7.**i18n keys live in `src/locales/default/plugin.ts`.** Inspector titles must come from `t('builtins.<identifier>.apiName.<api>')` so something renders while args stream.
└── components/ # shared subcomponents used by the surfaces above
```
**Older packages** (`builtin-tool-task`, `builtin-tool-calculator`, etc.) still have `src/executor/` as a sibling of `src/client/`. That's grandfathered; **don't relocate without a deliberate refactor**. New packages and new APIs added to existing packages should follow the layout above.
| Pure-compute, no UI state | `packages/builtin-tool-calculator/` — `ExecutionRuntime` reuses executor (mathjs/nerdamer work everywhere) |
| CRUD over a domain entity | `packages/builtin-tool-task/` — full Inspector + Render set, batch variants |
| Heavy UI (Inspector/Render/Placeholder/Portal) | `packages/builtin-tool-web-browsing/` — search-style result UI, Portal for detail view |
| Desktop / filesystem with all surfaces (incl. Streaming + Intervention) | `packages/builtin-tool-local-system/` — `ExecutionRuntime` injects an `ILocalSystemService`, executor calls it |
| Server-side pure (no client executor) | `packages/builtin-tool-web-browsing/` — only `ExecutionRuntime` is exported; the chat client doesn't run it |
| Needs human approval before running | `packages/builtin-tool-local-system/src/client/Intervention/` — per-API approval components |
- Server bundles import only `./` and `./executionRuntime` and never touch React.
- Frontend bundles import `./client` and never touch Node-only services.
- The runtime is testable without React or Electron present.
---
## Why ExecutionRuntime is the Default Home for Logic
**Old pattern (grandfathered):** business logic in `src/executor/` directly. Examples: `builtin-tool-task`, older tools. Works, but the executor mixes runtime logic with frontend service plumbing — hard to reuse on the server.
**New pattern (preferred):** business logic in `src/ExecutionRuntime/`, frontend wiring in `src/client/executor/`. Examples: `builtin-tool-local-system`, `builtin-tool-web-browsing`, `builtin-tool-calculator`.
```
ExecutionRuntime
├─ accepts services via constructor (or `static create(opts)`)
├─ returns BuiltinServerRuntimeOutput (content + state + success)
└─ no React, no Zustand, no `@/services/...` direct imports
client/executor
├─ extends BaseExecutor<typeof <Name>ApiName>
├─ holds a `runtime = new <Name>ExecutionRuntime(realService)` instance
├─ each ApiName method:
│ 1. resolve scope / pull defaults from BuiltinToolContext
│ 2. call runtime.<method>(args)
│ 3. funnel through toResult() → BuiltinToolResult
└─ exported singleton: export const <name>Executor = new <Name>Executor()
```
### Service injection
`ExecutionRuntime` should declare a TypeScript interface for the services it needs and accept the implementation via constructor. Server callers wire in real implementations; tests wire in mocks. Example from `local-system`:
### When ExecutionRuntime is the only thing you ship
Some tools are server-only — there's no frontend executor. `builtin-tool-web-browsing` is the canonical example: only `./` and `./executionRuntime` are exported, no `./executor`, and the runtime is constructed by the server-side `ToolExecutionService`. Skip `client/executor/` entirely for those.
### When the executor reuses the runtime as-is
Pure-compute tools (`builtin-tool-calculator`) often have an executor whose ApiName methods call `executor.calculate(args)` and an `ExecutionRuntime` whose methods call `calculatorExecutor.calculate(args)` — same logic, two thin wrappers. That's fine; the duplication buys you the bundle split.
content: string;// the LLM-facing text — never undefined; default to error message
state?: any;// result-domain object the UI reads as pluginState
success: boolean;// mandatory
error?: any;// raw error; the executor will repackage
}
```
### `BuiltinToolResult` (what the executor returns to the runtime)
```ts
{
success: boolean;
content?: string;
state?: any;
error?:{type:string;message: string;body?: any};
metadata?: Record<string,any>;// rare; e.g. { agentCouncil: true }
stop?: boolean;// rare; halt the orchestration step
}
```
### The `toResult` funnel (mandatory)
Every executor method returns through a single `toResult()` to enforce two invariants:
1.**`content` is never undefined.** A missing content collapses downstream into `''`, leaving the Debug pane blank while `pluginState` was already saved. See the `globLocalFiles` regression in `local-system/src/client/executor/index.ts:60-84`.
2.**`state` survives failures.** Renderers can keep showing partial output even when `success: false`.
return(thisasany)[apiName](params,ctx);// method name MUST equal apiName value
```
So:
- **Method names must equal `<Name>ApiName` values, exactly.** A typo silently routes to "ApiNotFound".
- **Methods must be class fields, not class methods**, because `this` is lost when registry calls `executor.invoke(apiName, params, ctx)`. Always declare as `methodName = async (…) => { … }`.
- **Always destructure `apiEnum` and `identifier` as `readonly` instance fields**, not getters — `BaseExecutor.hasApi/getApiNames` reads them synchronously.
---
## `BuiltinToolContext` — What the Executor Receives
The runtime hands every executor method an optional `BuiltinToolContext` as the second argument:
For dev preview, also seed `locales/zh-CN/plugin.json` and `locales/en-US/plugin.json`. Run `pnpm i18n` before opening a PR — it's slow, so do it once at the end. (See the **i18n** skill for the full workflow.)
---
## Registry Wiring
Five core files plus optional ones. Miss any and you'll see "tool not found", a missing chip, a blank result card, a stuck spinner, or an approval dialog that never appears.
| `packages/builtin-tools/src/index.ts` | Import `<Name>Manifest`; push entry to `builtinTools`. Set `hidden`/`discoverable` flags. |
| `packages/builtin-tools/src/identifiers.ts` | Add `<Name>Manifest.identifier` to `builtinToolIdentifiers`. |
| `packages/builtin-tools/src/inspectors.ts` | Import `<Name>Inspectors, <Name>Manifest`; add to `BuiltinToolInspectors`. |
| `src/store/tool/slices/builtin/executors/index.ts` | Import `<name>Executor`; add to `registerExecutors([…])`. |
| **Conditional — add only if the surface exists** | |
| `packages/builtin-tools/src/renders.ts` | Add to `BuiltinToolsRenders` if any API has a Render. |
| `packages/builtin-tools/src/placeholders.ts` | Add to `BuiltinToolPlaceholders` if any API has a Placeholder. |
| `packages/builtin-tools/src/streamings.ts` | Add to `BuiltinToolStreamings` if any API has a Streaming renderer. |
| `packages/builtin-tools/src/interventions.ts` | Add to `BuiltinToolInterventions` if any API has an Intervention component. |
| `packages/builtin-tools/src/portals.ts` | Add to `BuiltinToolsPortals` if the tool has a Portal. |
| `packages/builtin-tools/src/displayControls.ts` | Add if Render must show/hide based on result content (rare; see ClaudeCode/Codex). |
### Optional flags in `packages/builtin-tools/src/index.ts`
```ts
{
identifier: TaskManifest.identifier,
manifest: TaskManifest,
type:'builtin',
hidden: true,// hide from chat-input Tools popover
discoverable: false,// exclude from agent builder / skill discovery
}
```
Lists in the same file you may need to touch:
-`defaultToolIds` — added to the agent's tool list by default
-`alwaysOnToolIds` — forced on regardless of user selection (use sparingly)
-`runtimeManagedToolIds` — enable state controlled by runtime, not user UI; **must mirror the rules map** in `src/server/modules/Mecha/AgentToolsEngine/index.ts` and `src/helpers/toolEngineering/index.ts`
This doc covers everything that **isn't UI**: the tool's identifier, API surface, manifest, types, system prompt, ExecutionRuntime, and the executor that wires it into the frontend.
For UI surfaces (Inspector / Render / Placeholder / Streaming / Intervention / Portal), see [ui.md](ui.md).
For where files live and how registries work, see [architecture.md](architecture.md).
- **`lobe-` prefix is mandatory** — many switches in the codebase key off it.
- Pick a **domain noun**, not a verb (`lobe-task`, not `lobe-task-manager`).
- The identifier is **persisted in message history** — renaming after release means the `@deprecated` alias trick (register the legacy identifier as a second key in `inspectors.ts` / `renders.ts` pointing at the new module). Get it right the first time.
- **Plural variant for batch** (`createTasks`, `runTasks`) — describe in the manifest description that it's preferred over multiple single calls. The system prompt should also push the batch form.
- Reserve **clear separation between mutating verbs** (`updateTaskStatus`, `editTask`) and **execution verbs** (`runTask`). The system prompt must warn the model when these are confusable — see `task` for the canonical "do NOT use updateTaskStatus(running) to start a task" warning.
Define `<Name>ApiName` as `as const` so it doubles as a runtime enum (used by `BaseExecutor`) and a literal type. Then declare `Params` and `State` per API.
```ts
exportconstTaskIdentifier='lobe-task';
exportconstTaskApiName={
createTask:'createTask',
createTasks:'createTasks',
listTasks:'listTasks',
/* …one entry per API, group logically (CRUD then run-style) */
**The result-domain rule for `State`** (memory: "pluginState is result-domain, not call-domain"):
- Include only fields the UI **renders after the call returns** — ids the LLM didn't have when calling, counts, summary numbers, server-assigned status.
- **Don't echo all params.** The Inspector/Render gets `args` for free.
- Keep batch results as `{ succeeded, failed, results }` so the Render can show a one-line summary plus a detail list.
description:'Detailed instruction for what the task should accomplish.',
},
parentIdentifier:{
type:'string',
description:
'Identifier of the parent task (e.g. "TASK-1"). If provided, the new task becomes a subtask.',
},
priority:{
type:'number',
description:'Priority level: 0=none, 1=urgent, 2=high, 3=normal, 4=low. Default is 0.',
},
},
},
},
/* …one entry per ApiName */
],
};
```
### Manifest writing checklist
- **Every API in `<Name>ApiName` has exactly one entry in `api[]`.** Easy to drift after a refactor.
- **`description` on each API is the model's only docs.** Make it long enough for the LLM to pick the right tool. Mention edge cases ("If you provide any filter, omitted filters are not applied implicitly"), defaults, and the relationship to sibling APIs ("To START a task, use runTask — updateTaskStatus only flips a flag").
- **`parameters` is JSON Schema** (`LobeChatPluginApi`). Use `enum`, `required`, `items`, `oneOf`, `additionalProperties: false` etc. — these survive into the LLM's tool spec.
- **Use `additionalProperties: false`** on parameter objects so the model can't sneak unknown fields past validation.
- **Number parameters with semantic values** (`priority: 0=none, 1=urgent, …`) should describe the mapping in the description. Don't rely on `enum` alone for numbers — the model often fills the wrong one.
- **`enum` arrays for known string sets** (statuses, categories, engines). Spread from a constants module (`enum: [...TASK_STATUSES]`) so the manifest stays in sync.
### Optional manifest fields
```ts
{
/* Where this tool can run.
'client' → Agent Gateway dispatches to the desktop client (filesystem, Electron only)
'server' → ToolExecutionService runs it on the server
omitted → server only */
executors:['client','server'],
/* Default human intervention policy for all APIs that don't specify one.
Pair with an Intervention component (see ui.md). */
Per-API `humanIntervention` and `renderDisplayControl` go inside each `api[]` entry.
---
## 4. `systemRole.ts` — Operator Instructions for the Model
This is appended to the agent system prompt whenever the tool is enabled. Treat it as a **how-to-use guide for the LLM**, not marketing copy.
```ts
exportconstsystemPrompt=`You have access to Task management tools. Use them to:
- **createTask**: Create a new task. Use parentIdentifier to make it a subtask.
- **createTasks**: Prefer this over multiple createTask calls when planning a batch
(e.g. all subtasks under one parent, or all chapters of an outline).
- **runTask**: Actually START a task — kicks off the agent in a new (or continued)
topic. Do NOT use updateTaskStatus(running) to start a task; that only flips a
flag without executing. The task must have an assigneeAgentId.
- **updateTaskStatus**: Change a task's status (completed/cancelled/paused/failed).
If you mark a task as failed, include an error message explaining why.
- ...
When planning work:
1. Create tasks for each major piece (use parentIdentifier to organize as subtasks).
2. Use editTask with addDependencies to control execution order.
3. Use updateTaskStatus to mark the current task completed when done.`;
```
### Patterns that work well
- **Bulleted list, bold the API name, one line per API.** The model picks tools by skimming.
- **Disambiguate confusable APIs explicitly** (`runTask` vs `updateTaskStatus`).
- **Push toward batched APIs** ("Prefer this when…").
- **End with a numbered workflow** if the tool has a typical sequence.
- **For tools with multiple environments** (e.g. desktop vs cloud), keep variants in `systemRole.ts` and `systemRole.desktop.ts` and pick at the manifest level. See `builtin-tool-local-system`.
### Dynamic system prompts
If the prompt depends on runtime state (current date, available models), export a function and call it in the manifest:
```ts
// systemRole.ts
exportconstsystemPrompt=(today: string)=>`Today is ${today}. You have web search tools…`;
Use when the same logic runs in browser and Node (e.g. mathjs, nerdamer). The runtime is a thin wrapper that imports the executor and re-types the state per API. See `builtin-tool-calculator/src/ExecutionRuntime/index.ts` for the canonical example.
### Pattern C: Extend a shared base
When you're implementing a domain that already has a base runtime (file ops via `ComputerRuntime`), extend and only override `callService` + result normalization. See `builtin-tool-local-system/src/ExecutionRuntime/index.ts`.
### Runtime contract
Every method returns:
```ts
{
content: string;// LLM-facing — never undefined; default to error message
state?: any;// result-domain — what the UI's pluginState becomes
success: boolean;// mandatory
error?: any;// raw error object; the executor will repackage
}
```
Use `@lobechat/prompts` formatters (`searchResultsPrompt`, `crawlResultsPrompt`, `formatTaskCreated`, etc.) to produce structured `content`. They emit XML/markdown that's already tuned for token efficiency.
The executor's job is to **resolve frontend defaults** (current agent, current task, scope) and **call the runtime**. It then funnels through `toResult()` into the `BuiltinToolResult` shape.
1.**Methods are class fields** (`name = async (…) => {…}`), not class methods. The registry calls `(executor as any)[apiName](params, ctx)`; arrow-function fields keep `this` bound.
2.**`identifier` and `apiEnum` are `readonly` instance fields**, not getters — `BaseExecutor.hasApi/getApiNames` reads them synchronously at registration time.
3.**Default missing params from `ctx`**, but never silently override explicit values. Use `params.foo ?? ctx?.foo`, not `ctx?.foo ?? params.foo`.
4.**One funnel for all returns.** Either always return through `toResult(runtime.x())` (when delegating) or through `errorResult(…)` for the catch arm. Never inline `{ success: false, content: '' }` — `content: ''` collapses the Debug pane to blank.
5.**`debug('lobe-<name>:executor')`.** Match the namespace to the identifier minus `lobe-` when convenient.
6.**Singleton export.**`export const <name>Executor = new <Name>Executor()` — the registry imports the instance, not the class.
### When the executor delegates to ExecutionRuntime
The `toResult` funnel is **mandatory**: it enforces never-undefined `content` and partial-state preservation. Both invariants caught real production bugs (`globLocalFiles` Response empty, `editLocalFile` partial state lost).
---
## 7. `index.ts` — Package Entry Point
Keep it pure data + the manifest. **No React, no stores, no Node-only imports.**
**Why peer not direct deps for client libs:** the `./` and `./executionRuntime` entry points must be importable from server code. Listing React etc. as peer deps prevents bundlers from following them when only the runtime is consumed.
**Skip `./executor`** if the package has no frontend executor (server-only tools like `builtin-tool-web-browsing`).
| "ApiNotFound" at runtime | Method name in executor doesn't match `ApiName` value (typo, wrong case) |
| Method works once, then "this is undefined" | Method declared as `async fn() {}` instead of `fn = async () => {}` — `this` lost when registry invokes |
| Debug "Response" pane blank but `pluginState` populated | Returning `content: ''` or letting `output.content` be undefined — use the `toResult` funnel |
| Partial result vanishes on failure | `toResult` discarded `state` when `success: false`; preserve it |
| Tool shows up but doesn't run on desktop | `executors` in manifest doesn't include `'client'` (or vice versa for server-only) |
| Same tool registered twice / legacy identifier ghost | Identifier collision; check `@deprecated` aliases in `inspectors.ts`/`renders.ts` |
| Manifest test fails after adding API | Forgot to add the corresponding i18n `apiName.<api>` key |
| TypeScript error on `BaseExecutor<typeof X>` | `X` declared with `enum` instead of `as const` object — must be the const-object form |
A builtin tool can ship up to **six client-side surfaces**, each with a different role in the chat UI. Only `Inspector` is required; the other five are added on demand and registered in their own central files.
| Surface | Required? | When the chat shows it | Registered in |
Fall back to `createStyles + token` only when you need runtime token computation (rare). Inline `style={{ color: cssVar.colorTextSecondary }}` is fine for one-off dynamic values.
### 0.3 Use `@lobehub/ui`, not raw `antd`
`Block`, `Text`, `Flexbox`, `Highlighter`, `Alert`, `Tooltip`, `Skeleton` all come from `@lobehub/ui`. Modals come from `@lobehub/ui/base-ui` (`createModal`, `useModalContext`, `confirmModal`) — see the **modal** skill.
Memory note: `@lobehub/ui`'s `<Text type='secondary'>` is a lighter shade than `colorTextSecondary`. If you need that exact token color, write `<Text style={{ color: cssVar.colorTextSecondary }}>`.
### 0.5 Always type with `BuiltinXProps<Args, State>` generics
Don't widen to `any`. The Args generic is the JSON Schema params, the State generic is the executor's `state` field. The two should match `<Name>Params` and `<Name>State` from `types.ts`.
### 0.6 Pull strings from `t('plugin')`
```tsx
const{t}=useTranslation('plugin');
t('builtins.<identifier>.apiName.<api>');
```
Every Inspector should default to `t('builtins.<identifier>.apiName.<api>')` so it shows something while args stream in.
### 0.7 Read store state from `@/store/chat`, not props
Tool surfaces sometimes need cross-cutting state (loading, streaming buffer). Read it inside the component via Zustand selectors, not from props — props only carry args/state/messageId.
---
## 1. Inspector — Header Chip (required)
**Lifecycle:** Inspector renders for **every phase** of a tool call: while args are streaming in, while the executor is running, and after results come back. It's the only surface that's always visible.
**Goal:** keep it to a single line. Show what's happening with as much context as is currently available.
| Args streaming, no useful field yet | `isArgumentsStreaming === true`, `partialArgs.X` undefined | Just the API title with `shinyTextStyles.shinyText` |
| Args streaming, key field arrived | `partialArgs.X` populated | Title + key field chip, still pulse-animated |
| Args complete, executor running | `args` populated, `isLoading === true` | Same as above, still pulse-animated |
| Result arrived | `pluginState` populated, `isLoading === false` | Title + chips + result summary (count, identifier, status) |
- Wrap the whole row with `inspectorTextStyles.root` (provides correct flex / line-height baseline).
- Pulse with `shinyTextStyles.shinyText` whenever `isArgumentsStreaming || isLoading`.
- Show the i18n title first so the row is non-empty during the earliest streaming phase.
- Read both `args?.X` and `partialArgs?.X` together — `args` is final, `partialArgs` is in-stream.
- Use chips/tags for distinct facets (identifier, name, parent, status, count). Each chip should clip with `text-overflow: ellipsis` and have a `max-width` so long values don't blow out the chat bubble.
- Append `pluginState`-derived suffixes only **after** loading finishes — count or "(no results)" should not appear while still searching.
**Lifecycle:** rendered **once the result arrives** (after Placeholder/Streaming hand off). Sits below the Inspector header.
**Skip if** the API is read-only or the result is just text — the framework already shows the executor's `content` string. Add a Render only when there's a structured artifact worth seeing: a card, a chart, a diff, a list of files.
If the Render should hide for certain results (e.g. ClaudeCode's TodoWrite hides when the agent is mid-stream), add a `RenderDisplayControl` to `packages/builtin-tools/src/displayControls.ts`. See `ClaudeCodeRenderDisplayControls` for the pattern.
---
## 3. Placeholder — Skeleton Between Args and Result (optional)
**Lifecycle:** rendered when the args have finished streaming but the executor hasn't returned yet. Disappears when `pluginState` arrives. Bridges the moment of perceived lag.
**Add for** APIs with noticeable execution time: web search, network crawl, file list, large grep. **Skip for** instant ops (status flips, calculator).
- **Mirror the eventual Render's layout.** When the result arrives the Placeholder unmounts and the Render mounts; if they share dimensions, the chat doesn't jump.
- Use `Skeleton.Block` / `Skeleton.Button` from `@lobehub/ui` for placeholder shapes.
- Embed any args you have (e.g. the query text) — context helps the user know what's loading.
- Pulse with `shinyTextStyles.shinyText` if the Placeholder includes literal text.
## 4. Streaming — Live Output During Execution (optional)
**Lifecycle:** rendered **while the executor is still running** for APIs that emit incremental output. The component is responsible for fetching the in-flight stream from the chat store and rendering it.
messageId: string;// use to fetch the streaming buffer from store
toolCallId: string;
}
```
Note there's **no `state` or `result` prop** — the Streaming component is for the in-flight phase. It pulls the live buffer from the store itself (typically via `chatToolSelectors.streamingContent(messageId)` or similar).
**Lifecycle:** rendered **before the executor runs** for APIs whose manifest sets `humanIntervention`. The user sees a preview of the args, can edit them, then approves or skips/cancels.
- **Show a preview, not a form by default.** Editing UI is opt-in via `onArgsChange` and is usually inline (click to edit a code block, etc.).
- For args with debounced edit state (text fields), use `registerBeforeApprove(id, flushFn)` so the approve action waits for the debounce to flush. Always return the cleanup function.
- Call `onInteractionAction({ type: 'submit', payload })` when the user approves; `'skip'` if they skip with a reason; `'cancel'` if they cancel the whole turn.
- Add a corresponding `interventionAudit.ts` in the package root if the tool needs scope/path validation before approval (see `local-system/src/interventionAudit.ts`).
**Lifecycle:** rendered when the user opens the tool message in a side panel or full-screen modal. One Portal per **tool**, not per API — the Portal switches on `apiName` internally.
**Add for** tools whose results deserve a deep-dive view: search results with editable filters, page content with reader mode, code interpreter sessions.
| Portal opens but blank | Switch in `Portal/index.tsx` doesn't cover the apiName | | |
| Strings show as `builtins.lobe-foo.apiName.bar` | Missing i18n key in `src/locales/default/plugin.ts` (or not seeded in dev locale files) | | |
| Wrong color shade on `<Text type="secondary">` | `type='secondary'` is lighter than `colorTextSecondary` — pass via `style={{ color: cssVar.colorTextSecondary }}` | | |
| `@chat-adapter/state-redis` | Redis state (production) |
| `@chat-adapter/state-ioredis` | ioredis state (alternative) |
| `@chat-adapter/state-memory` | In-memory state (development) |
## Changesets (Release Flow)
This monorepo uses [Changesets](https://github.com/changesets/changesets) for versioning and changelogs. Every PR that changes a package's behavior must include a changeset.
# → choose bump type: patch (fixes), minor (features), major (breaking)
# → write a short summary for the CHANGELOG
```
This creates a file in `.changeset/` — commit it with the PR. When merged to `main`, the Changesets GitHub Action opens a "Version Packages" PR to bump versions and update CHANGELOGs. Merging that PR publishes to npm.
## Webhook setup
Each adapter exposes a webhook handler via `bot.webhooks.{platform}`. Wire these to your HTTP framework's routes (e.g. Next.js API routes, Hono, Express).
- **If reachable** (returns any HTTP status): server is running. Skip to Step 2.
- **If unreachable**: start the server:
```bash
# From cloud repo root
pnpm run dev:next
```
To **restart** (pick up server-side code changes):
```bash
lsof -ti:3011 | xargs kill
pnpm run dev:next
```
**Important:** Server-side code changes in the submodule (`lobehub/src/server/`, `lobehub/packages/`) require a server restart. Next.js hot-reload may not pick up changes in submodule packages.
- **If file exists and contains `"serverUrl": "http://localhost:3011"`**: already authenticated. Skip to Step 3.
- **If file missing or points to wrong server**: login is needed. Ask the user to run:
```bash
! cd lobehub/apps/cli &&LOBEHUB_CLI_HOME=.lobehub-dev bun src/index.ts login --server http://localhost:3011
```
> Login requires interactive browser authorization (OIDC Device Code Flow), so the user must run it themselves via `!` prefix. After login, credentials are saved to `lobehub/apps/cli/.lobehub-dev/` and persist across sessions.
### Step 3: Test with CLI Commands
CLI runs from source (`bun src/index.ts`), so CLI-side code changes take effect immediately without rebuilding.
```bash
cd lobehub/apps/cli
LOBEHUB_CLI_HOME=.lobehub-dev bun src/index.ts <command>
```
### Step 4: Clean Up Test Data
Delete any test data created during verification:
```bash
LOBEHUB_CLI_HOME=.lobehub-dev bun src/index.ts task delete < id > -y
LOBEHUB_CLI_HOME=.lobehub-dev bun src/index.ts agent delete < id > -y

# LobeHub CLI Development Guide
## Overview
LobeHub CLI (`@lobehub/cli`) is a command-line tool for managing and interacting with LobeHub services. Built with Commander.js + TypeScript.
- **Package**: `apps/cli/`
- **Entry**: `apps/cli/src/index.ts`
- **Binaries**: `lh`, `lobe`, `lobehub` (all aliases for the same CLI)
- **Build**: tsup
- **Runtime**: Node.js / Bun
## Architecture
```
apps/cli/src/
├── index.ts # Entry point, registers all commands
The base directory (`~/.lobehub/`) can be overridden with the `LOBEHUB_CLI_HOME` env var (e.g. `LOBEHUB_CLI_HOME=.lobehub-dev` for dev mode isolation).
## Key Dependencies
-`commander` - CLI framework
-`@trpc/client` + `superjson` - Type-safe API client
-`@lobechat/local-file-shell` - Local shell/file tool execution
-`picocolors` - Terminal colors
-`ws` - WebSocket
-`diff` - Text diffing
-`fast-glob` - File pattern matching
## Development
### Running in Dev Mode
Dev mode uses `LOBEHUB_CLI_HOME=.lobehub-dev` to isolate credentials from the global `~/.lobehub/` directory, so dev and production configs never conflict.
```bash
# Run a command in dev mode (from apps/cli/)
cd apps/cli && bun run dev -- <command>
# This is equivalent to:
LOBEHUB_CLI_HOME=.lobehub-dev bun src/index.ts <command>
```
### Connecting to Local Dev Server
To test CLI against a local dev server (e.g. `localhost:3011`):
**Step 1: Start the local server**
```bash
# From cloud repo root
bun run dev
# Server starts on http://localhost:3011 (or configured port)
```
**Step 2: Login to local server via Device Code Flow**
```bash
cd apps/cli && bun run dev -- login --server http://localhost:3011
```
This will:
1. Call `POST http://localhost:3011/oidc/device/auth` to get a device code
2. Print a URL like `http://localhost:3011/oidc/device?user_code=XXXX-YYYY`
3. Open the URL in your browser — log in and authorize
4. Save credentials to `apps/cli/.lobehub-dev/credentials.json`
5. Save server URL to `apps/cli/.lobehub-dev/settings.json`
After login, all subsequent `bun run dev -- <command>` calls will use the local server.
**Step 3: Run commands against local server**
```bash
cd apps/cli && bun run dev -- task list
cd apps/cli && bun run dev -- task create -i "Test task" -n "My Task"
cd apps/cli && bun run dev -- agent list
```
**Troubleshooting:**
- If login returns `invalid_grant`, make sure the local OIDC provider is properly configured (check `OIDC_*` env vars in `.env`)
- If you get `UNAUTHORIZED` on API calls, your token may have expired — run `bun run dev -- login --server http://localhost:3011` again
- Dev credentials are stored in `apps/cli/.lobehub-dev/` (gitignored), not in `~/.lobehub/`
### Switching Between Local and Production
```bash
# Dev mode (local server) — uses .lobehub-dev/
cd apps/cli && bun run dev -- <command>
# Production (app.lobehub.com) — uses ~/.lobehub/
lh <command>
```
The two environments are completely isolated by different credential directories.
### Build & Test
```bash
# Build CLI
cd apps/cli && bun run build
# Unit tests
cd apps/cli && bun run test
# E2E tests (requires authenticated CLI)
cd apps/cli && bunx vitest run e2e/kb.e2e.test.ts
# Link globally for testing (installs lh/lobe/lobehub commands)
-`src/server/routers/lambda/video/index.ts` — video creation (uses `authedProcedure` + `serverDatabase`)
-`src/server/routers/lambda/generation.ts` — status checking
-`packages/database/src/models/asyncTask.ts` — `AsyncTaskModel` including `checkTimeoutTasks`
**Note**: Image/video routes do NOT use the `keyVaults` middleware — they read API keys from the database via `initModelRuntimeFromDB` or `createAsyncCaller`.
Manage knowledge bases for RAG (Retrieval-Augmented Generation). Supports directory tree structure with folders, documents, and file uploads.
**Source**: `apps/cli/src/commands/kb.ts`
### `lh kb list`
```bash
lh kb list [--json [fields]]
```
**Table columns**: ID, NAME, DESCRIPTION, UPDATED
### `lh kb view <id>`
```bash
lh kb view [fields]] < id > [--json
```
**Displays**: Name, description, full directory tree with all files and documents (recursively fetched). Shows indented tree structure with item type (File/Doc), file type, and size.
**API**: Uses `file.getKnowledgeItems` to recursively fetch items. Folders (`custom/folder` fileType) are traversed in parallel via `Promise.all` for performance.
This generates an empty SQL file and properly updates `_journal.json` and snapshot. Then edit the generated SQL file to add your custom SQL:
```sql
-- Custom SQL migration file, put your code below! --
CREATEEXTENSIONIFNOTEXISTSpg_search;
```
**Do NOT manually create migration files or edit `_journal.json`** — always use `drizzle-kit generate` to ensure correct journal entries and snapshots.
After renaming the migration SQL file in Step 2, update the `tag` field in `packages/database/migrations/meta/_journal.json` to match the new filename (without `.sql` extension).

# Heterogeneous Agent Development
Use this skill when the bug or feature lives in the external CLI agent pipeline, not the normal server-side agent runtime.
## Use This Skill For
- Adding or changing a driver under `apps/desktop/src/main/modules/heterogeneousAgent/drivers/`
- Editing an adapter under `packages/heterogeneous-agents/src/adapters/`
- Debugging `heteroAgentRawLine` transport, `window.__HETERO_AGENT_TRACE`, or `executeHeterogeneousAgent`
- Fixing Claude Code stream-json bugs such as duplicate partial/full chunks, broken `message.id` boundaries, missing `tool_result`, TodoWrite state drift, or subagent thread routing
- Fixing Codex JSONL bugs such as mixed multi-tool messages, broken turn boundaries, or missing tool-result mapping
- Fixing step-boundary, tool persistence, subagent thread, or resume bugs in Claude Code / Codex flows
You are being run only to collect a raw Codex JSON event trace.
Do not modify any files.
Use at least 4 separate shell tool invocations, one invocation per command.
Run a short sequence of read-only repo checks and then reply with a one-sentence summary.
EOF
```
What to look for in the JSONL:
-`thread.started`
-`turn.started`
-`item.started` / `item.completed`
-`item.type === 'command_execution'`
-`item.type === 'agent_message'`
-`turn.completed`
If raw Codex already merges tools into one item, the adapter is innocent. If raw Codex emits independent items but UI collapses them, the bug is downstream.
If the repo already contains useful traces under `.heerogeneous-tracing/`, inspect them before reproducing.
### Claude Code raw NDJSON
Mirror the arguments from `apps/desktop/src/main/modules/heterogeneousAgent/drivers/claudeCode.ts`.
-`-p`
-`--input-format stream-json`
-`--output-format stream-json`
-`--verbose`
-`--include-partial-messages`
-`--permission-mode bypassPermissions`
You can capture a local raw trace like this:
```bash
ts=$(date +%Y%m%d-%H%M%S)
out=".heerogeneous-tracing/claude-${ts}.ndjson"
cat << 'EOF' | claude -p \
--input-format stream-json \
--output-format stream-json \
--verbose \
--include-partial-messages \
--permission-mode bypassPermissions \
> "$out"
{"type":"user","message":{"role":"user","content":[{"type":"text","text":"Do a few read-only repo checks, use several tool calls, and then summarize briefly."}]}}
EOF
```
What to look for in Claude Code raw traces:
-`type: 'system', subtype: 'init'`
-`type: 'assistant'` blocks for `thinking`, `tool_use`, and `text`
-`type: 'user'` blocks containing `tool_result`
-`type: 'stream_event'` with `message_start`, `content_block_delta`, and `message_delta`
-`type: 'result'`
-`type: 'rate_limit_event'`
Important Claude Code semantics:
- Each content block often arrives as its own assistant event.
- Multiple assistant events can share the same `message.id`; that is still one turn.
-`message.id` change is the main-step boundary.
- Partial deltas arrive before the later full assistant block.
-`message_delta.usage` is the authoritative per-turn usage.
- Subagent events are tagged with `parent_tool_use_id`.
If the repo already contains useful references, inspect these first:
Codex raw traces usually provide turn-level boundaries through:
-`turn.started`
-`turn.completed`
The executor only cuts a new assistant message when it receives a step-boundary signal it understands. If the adapter emits `stream_start` without `newStep`, multiple Codex tools and text chunks can accumulate under the same assistant longer than intended.

# LobeHub Internationalization Guide
- Default language: English (en-US)
- Framework: react-i18next
- **Only edit files in `src/locales/default/`** - Never edit JSON files in `locales/`
- Run `pnpm i18n` to generate translations (or manually translate zh-CN/en-US for dev preview)
## Key Naming Convention
**Flat keys with dot notation** (not nested objects):
description: "Linear issue management. MUST USE when: (1) user mentions LOBE-xxx issue IDs (e.g. LOBE-4540), (2) user says 'linear', 'linear issue', 'link linear', (3) creating PRs that reference Linear issues. Provides workflows for retrieving issues, updating status, and adding comments."
---
# Linear Issue Management
Before using Linear workflows, search for `linear` MCP tools. If not found, treat as not installed.
## ⚠️ CRITICAL: PR Creation with Linear Issues
**When creating a PR that references Linear issues (LOBE-xxx), you MUST:**
1. Create the PR with magic keywords (`Fixes LOBE-xxx`)
2.**IMMEDIATELY after PR creation**, add completion comments to ALL referenced Linear issues
3. Do NOT consider the task complete until Linear comments are added
This is NON-NEGOTIABLE. Skipping Linear comments is a workflow violation.
## Workflow
1.**Retrieve issue details** before starting: `mcp__linear-server__get_issue`
2.**Read images**: If the issue description contains images, MUST use `mcp__linear-server__extract_images` to read image content for full context
3.**Check for sub-issues**: Use `mcp__linear-server__list_issues` with `parentId` filter
4.**Mark as In Progress**: When starting to plan or implement an issue, immediately update status to **"In Progress"** via `mcp__linear-server__update_issue`
5.**Update issue status** when completing: `mcp__linear-server__update_issue`
When creating issues with `mcp__linear-server__create_issue`, **MUST add the `claude code` label**.
## Language
Issue titles, descriptions, and comments **MUST follow the language of the current conversation**, not default to English.
- Conversation in 中文 → issue body in 中文；technical terms (file paths, identifiers, library names, commands, error messages) stay in English.
- Conversation in English → issue body in English.
- Code blocks, file paths, and quoted strings always stay in their original form regardless of surrounding language.
- This applies equally to **updates** — when editing an existing issue (description **and titles**), preserve the language of the conversation that triggered the edit; do not switch the issue language during a refactor (Chinese → English or vice versa).
Rationale: the issue is a continuation of the conversation. Forcing English when the discussion is in Chinese creates translation friction for the collaborator who came from that thread.
## Creating Sub-issue Trees
When breaking a parent issue into a tree of sub-issues (e.g., task decomposition for LOBE-xxx), follow these rules — they work around real limitations of the Linear MCP tools.
### 1. ALWAYS prefix titles with an ordering index
The Linear Sub-issues panel displays children by `sortOrder`, which **defaults to newest-first** (most recently created appears on top). Neither parallel nor serial creation will produce the intended top-to-bottom reading order, and the MCP `save_issue` tool does **not expose a `sortOrder` parameter** — you cannot set order at create time.
**Workaround**: encode execution order in the title itself:
```plaintext
[1] [db] add schema fields
[2] [db] new table + repository
[3] [service] business logic layer
[4] [api] REST endpoints
[4.1] [sdk] client SDK wrapper
[4.1.1] [app] consumer integration
[4.1.2] [app] UI surface
[4.2] [ui] dashboard page
```
Even when the panel shuffles, the reader can mentally reconstruct the dependency graph at a glance. Dotted numbering `[n.m.k]` should mirror the parent-child nesting so the index and the tree agree.
### 2. Nest sub-issues by logical parent-child, not flat under the root
Linear supports **unlimited sub-issue depth**. A flat list of 8+ siblings under one root is hard to scan. Group by main-subordinate logic:
- Core service → its SDK → SDK consumers
- Don't create a sibling when a child is more accurate
Use `parentId: "LOBE-xxxx"` at creation (or `save_issue` to move). Moving an issue's parent does not disturb its `blockedBy` relations.
### 3. Sub-issue creation order is dictated by `blockedBy`
`blockedBy` requires the blocker to exist first (you need its LOBE-id). So:
1.**Topologically sort** the DAG — leaves (no deps) first, roots last
2. Create issues with zero deps in the first wave
3. Create dependent issues only after collecting the blocker IDs from prior responses
4.`blockedBy` is **append-only**; passing it again does not overwrite — safe to re-run
### 4. Don't waste rounds trying to parallelize
MCP tool calls in a single message look parallel but execute sequentially on the server, and you still need blocker IDs from earlier responses. Just issue calls in dependency order; optimizing for parallelism gains nothing here.
### 5. Keep each sub-issue description self-contained
Each sub-issue should state:
- Goal (1–2 lines)
- Key files to touch
- Concrete changes / acceptance criteria
- Dependencies (link to blocker issues by `LOBE-xxxx`)
- Validation steps
The implementer may open only the sub-issue, not the parent — don't rely on context that lives only in the parent description.
## Completion Comment Format
Every completed issue MUST have a comment summarizing work done:
```markdown
## Changes Summary
- **Feature**: Brief description of what was implemented
- **Files Changed**: List key files modified
- **PR**: #xxx or PR URL
### Key Changes
- Change 1
- Change 2
- ...
```
This is critical for:
- Team visibility
- Code review context
- Future reference
## PR Association (REQUIRED)
When creating PRs for Linear issues, include magic keywords in PR body:
-`Fixes LOBE-123`
-`Closes LOBE-123`
-`Resolves LOBE-123`
## Per-Issue Completion Rule
When working on multiple issues, update EACH issue IMMEDIATELY after completing it:
1. Complete implementation
2. Run `bun run type-check`
3. Run related tests
4. Create PR if needed
5. Update status to **"In Review"** (NOT "Done")
6.**Add completion comment immediately**
7. Move to next issue
**Note:** Status → "In Review" when PR created. "Done" only after PR merged.
**❌ Wrong:** Complete all → Create PR → Forget Linear comments

Install via `npm i -g agent-browser`, `brew install agent-browser`, or `cargo install agent-browser`. Run `agent-browser install` to download Chrome. Run `agent-browser upgrade` to update.
## Core Workflow
Every browser automation follows this pattern:
1.**Navigate**: `agent-browser open <url>`
2.**Snapshot**: `agent-browser snapshot -i` (get element refs like `@e1`, `@e2`)
3.**Interact**: Use refs to click, fill, select
4.**Re-snapshot**: After navigation or DOM changes, get fresh refs
Use `&&` when you don't need to read intermediate output. Run commands separately when you need to parse output first (e.g., snapshot to discover refs, then interact).
## Essential Commands
```bash
# Navigation
agent-browser open <url> # Navigate (aliases: goto, navigate)
agent-browser close # Close browser
agent-browser close --all # Close all active sessions
# Snapshot
agent-browser snapshot -i # Interactive elements with refs (recommended)
agent-browser snapshot -s "#selector"# Scope to CSS selector
# Interaction (use @refs from snapshot)
agent-browser click @e1 # Click element
agent-browser click @e1 --new-tab # Click and open in new tab
agent-browser fill @e2 "text"# Clear and type text
agent-browser type @e2 "text"# Type without clearing
echo"$PASSWORD"| agent-browser auth save myapp --url https://app.example.com/login --username user --password-stdin
agent-browser auth login myapp
# Option 2: Session name (auto-save/restore cookies + localStorage)
agent-browser --session-name myapp open https://app.example.com/login
agent-browser close # State auto-saved
agent-browser --session-name myapp open https://app.example.com/dashboard # Auto-restored
# Option 3: Persistent profile
agent-browser --profile ~/.myapp open https://app.example.com/login
# Option 4: State file
agent-browser state save auth.json
agent-browser state load auth.json
```
### LobeHub dev server — inject better-auth cookie
`agent-browser --headed` on macOS can create an off-screen Chromium window, blocking manual login. For a local LobeHub dev server (e.g. `localhost:3011`), copy the `better-auth.session_token` cookie out of a **Network request** in the user's own Chrome DevTools and load it via `state load`. See [references/agent-browser-login.md](./references/agent-browser-login.md) for the full recipe.
## Semantic Locators (Alternative to Refs)
```bash
agent-browser find text "Sign In" click
agent-browser find label "Email" fill "user@test.com"
agent-browser find role button click --name "Submit"
Refs (`@e1`, `@e2`, etc.) are invalidated when the page changes. Always re-snapshot after clicking links/buttons that navigate, form submissions, or dynamic content loading.
## Annotated Screenshots (Vision Mode)
```bash
agent-browser screenshot --annotate
# Output includes the image path and a legend:
# [1] @e1 button "Submit"
# [2] @e2 link "Home"
agent-browser click @e2 # Click using ref from annotated screenshot
```
## Parallel Sessions
```bash
agent-browser --session site1 open https://site-a.com
agent-browser --session site2 open https://site-b.com
agent-browser --cdp 9222 snapshot # Explicit CDP port
```
## iOS Simulator (Mobile Safari)
```bash
agent-browser device list
agent-browser -p ios --device "iPhone 16 Pro" open https://example.com
agent-browser -p ios snapshot -i
agent-browser -p ios tap @e1
agent-browser -p ios swipe up
agent-browser -p ios screenshot mobile.png
agent-browser -p ios close
```
## Observability Dashboard
```bash
agent-browser dashboard install
agent-browser dashboard start # Background server on port 4848
agent-browser dashboard stop
```
## Cloud Providers
Use `-p <provider>` to run against cloud browsers: `agentcore`, `browserbase`, `browserless`, `browseruse`, `kernel`.
## Browser Engine Selection
```bash
agent-browser --engine lightpanda open example.com # 10x faster, 10x less memory
```
## Electron (LobeHub Desktop)
### Setup / Teardown
Use the `electron-dev.sh` script to manage the Electron dev environment. It handles process lifecycle, waits for SPA readiness, and reliably kills all child processes (main + helpers + vite).
# Or auto-discover running Chrome with remote debugging
agent-browser --auto-connect snapshot -i
```

# Part 2: osascript (Native macOS App Bot Testing)
Use AppleScript via `osascript` to control native macOS desktop apps for bot testing. Works with any app that supports macOS Accessibility, no CDP or Chromium needed.
The pattern is the same for every platform:
1.**Activate** the app (`tell application "X" to activate`)
2.**Navigate** to a channel/chat (Quick Switcher `Cmd+K` or Search `Cmd+F`)
3.**Send** a message (clipboard paste `Cmd+V` + Enter)
4.**Wait** for the bot response
5.**Screenshot** for verification (`screencapture` + `Read` tool)
## Per-Platform References
Pick the file for your target platform — each contains activation, navigation, send-message, and verification snippets specific to that app:
For **shared osascript patterns** (activate, type, paste, screenshot, read accessibility, common workflow template, gotchas), see [references/osascript-common.md](./references/osascript-common.md). Read this first if you're new to osascript automation.

# Scripts
Ready-to-use scripts in `.agents/skills/local-testing/scripts/`:
| `test-discord-bot.sh` | Send message to Discord bot via osascript |
| `test-slack-bot.sh` | Send message to Slack bot via osascript |
| `test-telegram-bot.sh` | Send message to Telegram bot via osascript |
| `test-wechat-bot.sh` | Send message to WeChat bot via osascript |
| `test-lark-bot.sh` | Send message to Lark / 飞书 bot via osascript |
| `test-qq-bot.sh` | Send message to QQ bot via osascript |
### Window Screenshot Utility
`capture-app-window.sh` captures a screenshot of a specific app window using `screencapture -l <windowID>`. It uses Swift + CGWindowList to find the window by process name, so screenshots work correctly even when the window is on an external monitor or behind other windows.
Each script: activates the app, navigates to the channel/contact, pastes the message via clipboard, sends, waits, and takes a screenshot. Use the `Read` tool on the screenshot for visual verification.
---
# Screen Recording
Record automated demos using `record-app-screen.sh` (start/stop lifecycle, CDP screenshots + ffmpeg assembly). See [references/record-app-screen.md](references/record-app-screen.md) for full documentation.
Outputs to `.records/` directory (gitignored): `<name>.mp4` (video) + `<name>/` (screenshots every 3s).
---
# Gotchas
### agent-browser
- **Daemon can get stuck** — if commands hang, `agent-browser close --all` or `pkill -f agent-browser` to reset
- **HMR invalidates everything** — after code changes, refs break. Re-snapshot or restart
- **`snapshot -i` doesn't find contenteditable** — use `snapshot -i -C` for rich text editors
- **`fill` doesn't work on contenteditable** — use `type` for chat inputs
- **Screenshots go to `~/.agent-browser/tmp/screenshots/`** — read them with the `Read` tool
- **Dialogs block all commands** — if commands time out, check `agent-browser dialog status`
- **Default timeout is 25s** — override with `AGENT_BROWSER_DEFAULT_TIMEOUT` (ms) or use explicit waits
- **Shell quoting corrupts eval** — use `eval --stdin <<'EVALEOF'` for complex JS
### Electron-specific
- **Always use `electron-dev.sh stop` to clean up** — `pkill -f "Electron"` only kills the main process; helper processes (GPU, renderer, network) survive. The script finds and kills all of them via PID matching against the project's electron binary path.
- **`npx electron-vite dev` must run from `apps/desktop/`** — running from project root fails silently. The `electron-dev.sh` script handles this automatically.
- **Don't resize the Electron window after load** — resizing triggers full SPA reload
- **Store is at `window.__LOBE_STORES`** not `window.__ZUSTAND_STORES__`
### osascript
See [references/osascript-common.md](./references/osascript-common.md#gotchas) for the full osascript gotchas list (accessibility permissions, `keystroke` non-ASCII issues, locale-specific app names, rate limiting, etc.).
# Log `agent-browser` into a local LobeHub dev server
`agent-browser --headed` on macOS often creates the Chromium window off-screen — the user can't see or interact with it, so manual login inside the agent-browser session fails. Instead of sharing the user's real Chrome profile, copy the **better-auth session cookie** out of a request in DevTools and inject it into the agent-browser session as a Playwright-style state file.
## When to use
- You need `agent-browser` to reach an authenticated page on `http://localhost:<port>` (e.g. `localhost:3011`).
- The user already has a logged-in tab of the same dev server in their own Chrome.
- Spawning a headed Chromium to let the user log in manually is unreliable (window off-screen, no interaction).
Do **not** use this on production URLs — only local dev. Treat the cookie as a secret: don't paste it into shared logs, PRs, or commit it anywhere.
## Step 1 — Ask the user to copy the cookie from a Network request, NOT `document.cookie`
`document.cookie` will not return HttpOnly cookies, which is exactly where better-auth puts its session. Instruct the user:
1. Open the logged-in tab (`http://localhost:<port>/…`) in their own Chrome.
2.`Cmd+Option+I` → **Network** tab.
3. Refresh, click any same-origin request (e.g. the top-level document request).
4. In the right pane under **Request Headers**, right-click the `Cookie:` line → **Copy value** (or copy the entire header).
5. Paste the string into chat.
You only need the better-auth pieces. Everything else (Clerk, `LOBE_LOCALE`, HMR hash, theme vars) is noise and can stay. The minimum viable set is:
**Note on `httpOnly`**: the real cookie in the user's browser is HttpOnly, but `storageState` doesn't enforce the flag on load — it just attaches the value. Storing with `httpOnly: false` is fine for local dev and sidesteps a CDP-context quirk where HttpOnly cookies sometimes fail to attach.
## Step 3 — Load state and navigate
```bash
SESSION="my-test"# any stable session name
agent-browser --session "$SESSION" state load /tmp/state.json
agent-browser --session "$SESSION" open "http://localhost:3011/"
agent-browser --session "$SESSION" get url
# Expect NOT /signin?callbackUrl=… — if you still see signin, cookie didn't apply.
```
## Step 4 — Verify
```bash
agent-browser --session "$SESSION" snapshot -i | head -20
# Look for the user's avatar/name in the sidebar, or absence of the signin form.
| Still redirects to `/signin` after `state load` | User pasted from `document.cookie` → missed HttpOnly session | Re-pull from Network request Headers, not console |
| `state load` reports 0 cookies | Separator wrong, or user pasted URL-decoded value | Keep the raw `Cookie:` header as-is; split on `"; "` |
| Login works briefly then expires | `better-auth.session_token` rotated (user logged out / signed in again) | Re-copy and re-load |
| Domain mismatch | Use `domain: "localhost"` literally, no leading dot for local dev | — |
## Scope
Only covers authenticating an **agent-browser** session into a **local** LobeHub dev server. It does not:
- Work for production — production cookies are `Secure; HttpOnly; Domain=.lobehub.com` and must be delivered over HTTPS.
- Replace real OAuth flows — tests that must exercise the login UI need a real Chromium with `--remote-debugging-port` or a bot account.
- Flow cookies back to the user's Chrome — injection is one-way (into agent-browser only).
Shared AppleScript / `osascript` patterns used by all platform bot tests. Read this first, then refer to the per-platform file for app-specific quirks.
## Core Patterns
### Activate an App
```bash
osascript -e 'tell application "Discord" to activate'
```
### Type Text
```bash
# Type character by character (reliable, but slow for long text)
osascript -e 'tell application "System Events" to keystroke "Hello world"'
# Press Enter
osascript -e 'tell application "System Events" to key code 36'
# Press Tab
osascript -e 'tell application "System Events" to key code 48'
# Press Escape
osascript -e 'tell application "System Events" to key code 53'
```
### Paste from Clipboard (fast, for long text)
```bash
# Set clipboard and paste — much faster than keystroke for long messages
osascript -e 'set the clipboard to "Your long message here"'
osascript -e 'tell application "System Events" to keystroke "v" using command down'
```
Or in one shot:
```bash
osascript -e '
set the clipboard to "Your long message here"
tell application "System Events" to keystroke "v" using command down
'
```
### Keyboard Shortcuts
```bash
# Cmd+K (quick switcher in Discord/Slack)
osascript -e 'tell application "System Events" to keystroke "k" using command down'
# Cmd+F (search)
osascript -e 'tell application "System Events" to keystroke "f" using command down'
# Cmd+N (new message/chat)
osascript -e 'tell application "System Events" to keystroke "n" using command down'
# Cmd+Shift+K (example: multi-modifier)
osascript -e 'tell application "System Events" to keystroke "k" using {command down, shift down}'
```
### Click at Position
```bash
# Click at absolute screen coordinates
osascript -e '
tell application "System Events"
click at {500, 300}
end tell
'
```
### Get Window Info
```bash
# Get window position and size
osascript -e '
tell application "System Events"
tell process "Discord"
get {position, size} of window 1
end tell
end tell
'
```
### Screenshot
```bash
# Full screen
screencapture /tmp/screenshot.png
# Interactive region select
screencapture -i /tmp/screenshot.png
# Specific window (by window ID from CGWindowList)
# Get all UI elements of the frontmost window (can be slow/large)
osascript -e '
tell application "System Events"
tell process "Discord"
entire contents of window 1
end tell
end tell
'
# Get a specific element's value
osascript -e '
tell application "System Events"
tell process "Discord"
get value of text field 1 of window 1
end tell
end tell
'
```
> **Warning:** `entire contents` can be extremely slow on complex UIs. Prefer screenshots + `Read` tool for visual verification.
### Read Screen Text via Clipboard
For reading the latest message or response from an app:
```bash
# Select all text in the focused area and copy
osascript -e '
tell application "System Events"
keystroke "a" using command down
keystroke "c" using command down
end tell
'
sleep 0.5
# Read clipboard
pbpaste
```
---
## Common Bot Testing Workflow
Regardless of platform, the pattern is:
```bash
APP_NAME="Discord"# or "Slack", "Telegram", "微信"
CHANNEL="bot-testing"
MESSAGE="Hello bot!"
WAIT_SECONDS=10
# 1. Activate
osascript -e "tell application \"$APP_NAME\" to activate"
sleep 1
# 2. Navigate to channel/chat (via Quick Switcher or Search)
osascript -e 'tell application "System Events" to keystroke "k" using command down'
sleep 0.5
osascript -e "tell application \"System Events\" to keystroke \"$CHANNEL\""
sleep 1
osascript -e 'tell application "System Events" to key code 36'
sleep 2
# 3. Send message
osascript -e "set the clipboard to \"$MESSAGE\""
osascript -e '
tell application "System Events"
keystroke "v" using command down
delay 0.3
key code 36
end tell
'
# 4. Wait for bot response
sleep "$WAIT_SECONDS"
# 5. Screenshot for verification
screencapture /tmp/"${APP_NAME,,}"-bot-test.png
echo"Result saved to /tmp/${APP_NAME,,}-bot-test.png"
```
### Tips
- **Use clipboard paste** (`Cmd+V`) for messages containing special characters or long text — `keystroke` can mangle non-ASCII
- **Add `delay`** between actions — apps need time to process UI events
- **Screenshot for verification** — use `screencapture` + `Read` tool for visual checks
- **Use a dedicated test channel/chat** — avoid polluting real conversations
- **Check app name** — some apps have different names in different locales (e.g., `微信` vs `WeChat`)
- **Accessibility permissions required** — System Events automation requires granting Accessibility access in System Preferences > Privacy & Security > Accessibility
---
## Gotchas
- **Accessibility permission required** — first run will prompt for access; grant it in System Preferences > Privacy & Security > Accessibility for Terminal / iTerm / Claude Code
- **`keystroke` is slow for long text** — always use clipboard paste (`Cmd+V`) for messages over \~20 characters
- **`keystroke` can mangle non-ASCII** — use clipboard paste for Chinese, emoji, or special characters
- **`key code 36` is Enter** — this is the hardware key code, works regardless of keyboard layout
- **`entire contents` is extremely slow** — avoid for complex UIs; use screenshots instead
- **App name varies by locale** — `微信` vs `WeChat`, `企业微信` vs `WeCom`; handle both
- **WeChat Enter sends immediately** — use `Shift+Enter` for newlines within a message
- **Rate limiting** — don't send messages too fast; platforms may throttle or flag automated input
- **Lark / 飞书 app name varies** — `Lark` (international) vs `飞书` (China mainland); scripts auto-detect
- **QQ uses `Cmd+F` for search** — not `Cmd+K` like Discord/Slack/Lark
- **Bot response times vary** — AI-powered bots may take 10-60s; use generous sleep values
General-purpose screen recording tool for the Electron app. Captures CDP screenshots as video frames and gallery snapshots, then assembles into an MP4 on stop.
## Why CDP Screenshots Instead of ffmpeg Screen Capture
- **Works on any screen** — CDP screenshots capture the browser viewport directly, so external monitors, Retina scaling, and window positioning are all handled automatically
- **No signal handling issues** — ffmpeg-static (npm) produces corrupt MP4 files when killed (missing moov atom). CDP screenshots avoid this entirely
- **Consistent output** — Screenshots are resolution-independent and don't require crop coordinate calculations
## Commands
```bash
# Start recording (Electron must be running with CDP)
agent_ref=$(echo"$snapshot"| grep 'link "'| grep -vE '"Home"|"Pages"|"Settings"|"Search"|"Resources"|"Marketplace"'| head -1 | grep -oE 'ref=e[0-9]+'| sed 's/ref=//'||true)
fi
if[ -z "$agent_ref"];then
echo"[error] No agent link found in snapshot"
echo"$snapshot"| head -30
return1

## Brand Principles
1.**Create**: One sentence → usable Agent; clear next step
You are **LobeHub’s English UI Copy & Microcopy Specialist**.
LobeHub is an assistant workspace: users can create **Agents** and **Agent Teams** so people↔agents and agent↔agent can collaborate to improve productivity in work and life.
Brand vibe: youthful, friendly, modern on the surface; professional, reliable, productivity- and controllability-first underneath. Overall style reference: Notion / Figma / Apple / Discord / OpenAI / Gemini — clear, restrained, trustworthy, human but not cheesy.
Product slogan: **For Collaborative Agents**. Your copy must continuously reinforce that LobeHub is not about “generation”, but about a **collaborative agent system**: shareable context, traceable outcomes, replayable runs, evolvable setup, and **human-in-the-loop**.
---
## 1) Fixed Terminology (must follow)
Use **exactly** these English terms across the product. Do not mix synonyms for the same concept.
- 空间: **Workspace**
- 助理: **Agent**
- 群组: **Group**
- 上下文: **Context**
- 记忆: **Memory**
- 连接器: **Integration**
- 技能 /tool/plugin: **Skill**
- 助理档案: **Agent Profile**
- 话题: **Topic**
- 文稿: **Page**
- 社区: **Community**
- 资源: **Resource**
- 库: **Library**
- MCP: **MCP**
- 模型服务商: **Provider**
Terminology rule: one concept = one term site-wide. Never alternate with “bot/assistant/AI agent/team/workspace” variations.
---
## 2) Your Responsibilities
- Improve, rewrite, or create from scratch any **English UI copy**: titles, buttons, form labels/help text, placeholders, onboarding, empty states, toasts, modals, errors, permission prompts, settings, creation/run flows, collaboration and Agent Team pages, etc.
- Copy must work for both:
- general users (immediately understandable)
- power users (not childish)
- It must fit both playful and serious contexts.
- Avoid overclaiming AI capabilities; add human warmth at the right moments.
---
## 3) The Three Brand Principles (bake into structure & wording)
- **Create**: create an Agent in one sentence; clear next step from idea → usable.
- **Collaborate**: multi-agent collaboration; align info and outputs; share Context (controlled, manageable).
- **Evolve**: Agents can remember preferences **only with user consent**; become more helpful over time; emphasize explainability, settings, and replay.
2.**Layered messaging (single version for everyone)**:
- Main line: simple and actionable
- Optional second line: more precise / technical / boundary-setting (subtitle, helper text, tooltip, collapsible)
- Do not produce “Pro vs Lite” variants; one main + optional detail
3.**Use terms sparingly but correctly**: prefer plain words (“connect”, “run”, “context”) unless a technical term is necessary. When it is, add a plain-English explanation.
4.**Consistency**: keep verbs consistent across similar actions (Create / Connect / Run / Pause / Retry / View details / Clear Memory).
5.**Actionable**: every message tells the user what to do next. Avoid generic “OK/Cancel”; use specific actions.
- Retry / View details / Go to Settings / Contact support / Copy logs
Never blame the user. Don’t show only an error code; put codes in “Details” if needed.
For data/security/billing: be neutral, thorough, and respectful—warmth comes from clarity, not emotion.
---
## 7) Your Special Task: CN i18n → EN (localized, length-aware)
You translate **raw Chinese i18n strings into English** for LobeHub.
Requirements:
- Prefer **localized**, product-native English over literal translation.
- Do **not** chase perfect one-to-one consistency if a more natural UI phrase reads better.
- Keep the **character length difference small**; try to make the English string **roughly the same visual length** as the Chinese source (avoid overly long expansions).
- Preserve meaning, tone, and actionability; keep verbs consistent with LobeHub’s UI patterns.
- If space is tight (buttons, tabs, toasts), prioritize: **verb + object**, drop optional words first.
- If the Chinese includes placeholders/variables, preserve them exactly (e.g., `{name}`, `{{count}}`, `%s`) and keep word order sensible.
- Keep capitalization consistent with UI norms (buttons/title case only when appropriate).
Output format when translating:
- Provide **English only**, unless asked otherwise.
- If multiple options are useful, give **one best option** + **one shorter fallback** (only when length constraints are likely).
---
You always optimize for: **clarity, control, collaboration, replayability, and human-in-the-loop**—in a modern, restrained, trustworthy English voice.
## 8) Product Introduction
LobeHub, we define agents as the unit of work. We’re building the first human–agent co-working, co-evolving network.
It is a fundamentally new, agent-first experience.You can pop up your agents or agent teams while writing, while chatting -- from ideation, to execution, to delivery -- across your entire workflow. Here, agents are not just tools, but always-on units of work.
### Create
It is a unified workspace where you can find, build, or team up with agent co-workers.Simply describe what you need, and Lobe AI will generate the prompts and assemble the right set of tools to compose your agent.In agent marketplace, you can easily discover agents created by others,use them instantly,and flexibly swap in your own tools.
### Collaboration
You can also spin up agent groups to handle system-level projects, even like building a quant team.
Within this group, some agents track signals and mine quantitative factors in real time, some manage risk, some execute orders, collaborate together to make money.
We’re defining how humans and agents work together. Now we support agent-to-agent collaboration, and we continue to scale new forms of collaboration networks — from agents collaborating across teams, to multiple humans working through the same agent.
### Evolve
Humans and agents should co-evolve, and we design this paradigm from both technical and economic perspectives. Our memory system is structured and editable,enabling models to better align with individual users, while allowing users to provide cleaner reward signals for continual learning. Agent evolution is powered by shared human intelligence through our agent marketplace. Creators are rewarded, and agents, in turn, pay for human intelligence.
Is AI replacing humans? No.
We’re building a human–agent co-working, co-evolving society.
Agents become smarter and more personalized through human intelligence, taking on repetitive and exhausting work — so humans can focus on fewer, but more important things: taste, and creation.
description: MUST use when creating, editing, or writing modal dialogs or imperative modals. Prefer createModal / useModalContext / confirmModal from @lobehub/ui/base-ui; root @lobehub/ui is legacy (antd Modal). Covers patterns, ModalHost, and migration notes.
user-invocable: false
---
# Modal Imperative API Guide
## Recommended: `@lobehub/ui/base-ui`
New code should use the **base-ui** modal stack (headless primitives, not antd `Modal`):
-`createModal`, `confirmModal`, `ModalHost` from `@lobehub/ui/base-ui`
-`useModalContext` from `@lobehub/ui/base-ui` inside modal **content**
Base-ui `createModal` renders through a **separate** host from the root package. The app must mount **`ModalHost`** from `@lobehub/ui/base-ui` once near the root (e.g. next to other global hosts). Without it, `createModal` calls will not appear.
If the project only mounts `ModalHost` from `@lobehub/ui`, add a second lazy `ModalHost` from `@lobehub/ui/base-ui` until all imperative modals are migrated.
| `content` | Main body (preferred name vs `children`) |
| `maskClosable` | Click outside to dismiss |
| `styles.*` | Semantic regions, not antd `styles.body` |
### Confirm
```tsx
import{confirmModal}from'@lobehub/ui/base-ui';
confirmModal({
title:'…',
content:'…',
okText:'…',
cancelText:'…',
onOk: async()=>{},
});
```
---
## Legacy: `@lobehub/ui` (root)
Older call sites use **`createModal` from `@lobehub/ui`**, which is typed as **antd `Modal` props** (`children`, `allowFullscreen`, `getContainer`, `destroyOnHidden`, `styles.body`, etc.). Prefer migrating new work to **`@lobehub/ui/base-ui`**.

# React Component Writing Guide
- Use antd-style for complex styles; for simple cases, use inline `style` attribute
- **Prefer `createStaticStyles` with `cssVar.*`** (zero-runtime) — module-level, no hook call required
- Only fall back to `createStyles` + `token` when styles genuinely need runtime computation (dynamic props, JS color fns like `readableColor`/`chroma`)
- See `.cursor/docs/createStaticStyles_migration_guide.md` for full pattern
- Use `Flexbox` and `Center` from `@lobehub/ui` for layouts (see `references/layout-kit.md`)
- Desktop router (pair — **always edit both** when changing routes): `src/spa/router/desktopRouter.config.tsx` (dynamic imports) and `src/spa/router/desktopRouter.config.desktop.tsx` (sync imports). Drift can cause unregistered routes / blank screen.
- Mobile router: `src/spa/router/mobileRouter.config.tsx`
- Router utilities: `src/utils/router.tsx`
### `.desktop.{ts,tsx}` File Sync Rule
**CRITICAL**: Some files have a `.desktop.ts(x)` variant that Electron uses instead of the base file. When editing a base file, **always check** if a `.desktop` counterpart exists and update it in sync. Drift causes blank pages or missing features in Electron.
**How to check**: After editing any `.ts` / `.tsx` file, run `Glob` for `<filename>.desktop.{ts,tsx}` in the same directory. If a match exists, update it with the equivalent sync-import change.

---
# OpenResponses Compliance Test
Run the official OpenResponses compliance test suite against the local (or remote) Response API endpoint.
## Quick Start
```bash
# From the openapi package directory
cd lobehub/packages/openapi
# Run all tests (dev mode, localhost:3010)
APP_URL=http://localhost:3010 bun run test:response-compliance -- \
| `APP_URL` | `http://localhost:3010` | Server base URL (auto-appends `/api/v1`) |
| `API_KEY` | — | API key (alternative to `--api-key` flag) |
## How It Works
The script (`lobehub/packages/openapi/scripts/compliance-test.sh`) clones the official [openresponses/openresponses](https://github.com/openresponses/openresponses) repo into `scripts/openresponses-compliance/` (gitignored) and runs its CLI test runner. First run clones; subsequent runs update from upstream.
## Debugging Failures
1. Run with `-v` to see full request/response payloads
2. Common failure patterns:
- **"Failed to parse JSON"**: Auth failed, server returned HTML redirect
- **"Response has no output items"**: LLM execution not yet implemented
- **"Expected number, received null"**: Missing required field in response schema
- **"Invalid input"**: Zod validation on response schema — check field format
description: 'Common recurring mistakes in LobeHub code review — console leftovers, missing return await, hardcoded secrets, hardcoded i18n strings, desktop router pair drift, antd vs @lobehub/ui, non-idempotent migrations, cloud impact red flags. Use as a quick checklist when reviewing PRs, diffs, or branch changes.'
---
# Review Checklist
## Correctness
- Leftover `console.log` / `console.debug` — should use `debug` package or remove
- Missing `return await` in try/catch — see <https://typescript-eslint.io/rules/return-await/> (not in our ESLint config yet, requires type info)
- Can the fix/implementation be more concise, efficient, or have better compatibility?
## Security
- No sensitive data (API keys, tokens, credentials) in `console.*` or `debug()` output
- No base64 output to terminal — extremely long, freezes output
- No hardcoded secrets — use environment variables
## Testing
- Bug fixes must include tests covering the fixed scenario
- New logic (services, store actions, utilities) should have test coverage
- Existing tests still cover the changed behavior?
- Prefer `vi.spyOn` over `vi.mock` (see `/testing` skill)
## i18n
- New user-facing strings use i18n keys, not hardcoded text
- Keys added to `src/locales/default/{namespace}.ts` with `{feature}.{context}.{action|status}` naming
- For PRs: `locales/` translations for all languages updated (`pnpm i18n`)
## SPA / routing
- **`desktopRouter` pair:** If the diff touches `src/spa/router/desktopRouter.config.tsx`, does it also update `src/spa/router/desktopRouter.config.desktop.tsx` with the same route paths and nesting? Single-file edits often cause drift and blank screens.
## Reuse
- Newly written code duplicates existing utilities in `packages/utils` or shared modules?
- Copy-pasted blocks with slight variation — extract into shared function
Use this skill when the user asks to run the migrated source command `dedupe`.
## Command Template
Find up to 3 likely duplicate issues for a given GitHub issue.
To do this, follow these steps precisely:
1. Use an agent to check if the Github issue (a) is closed, (b) does not need to be deduped (eg. because it is broad product feedback without a specific solution, or positive feedback), or (c) already has a duplicates comment that you made earlier. If so, do not proceed.
2. Use an agent to view a Github issue, and ask the agent to return a summary of the issue
3. Then, launch 5 parallel agents to search Github for duplicates of this issue, using diverse keywords and search approaches, using the summary from #1
4. Next, feed the results from #1 and #2 into another agent, so that it can filter out false positives, that are likely not actually duplicates of the original issue. If there are no duplicates remaining, do not proceed.
5. Finally, comment back on the issue with a list of up to three duplicate issues (or zero, if there are no likely duplicates)
Notes (be sure to tell this to your agents, too):
- Use `gh` to interact with Github, rather than web fetch
- Do not use other tools, beyond `gh` (eg. don't use other MCP servers, file edit, etc.)
- Make a todo list first
- For your comment, follow the following format precisely (assuming for this example that you found 3 suspected duplicates):
---
Found 3 possible duplicate issues:
1. <link to issue>
2. <link to issue>
3. <link to issue>
This issue will be automatically closed as a duplicate in 3 days.
- If your issue is a duplicate, please close it and 👍 the existing issue instead
- To prevent auto-closure, add a comment or 👎 this comment

# SPA Routes and Features Guide
SPA structure:
- **`src/spa/`** – Entry points (`entry.web.tsx`, `entry.mobile.tsx`, `entry.desktop.tsx`) and router config (`router/`). Router lives here to avoid confusion with `src/routes/`.
- **`src/routes/`** – Page segments only (roots).
- **`src/features/`** – Business logic and UI by domain.
This project uses a **roots vs features** split: `src/routes/` only holds page segments; business logic and UI live in `src/features/` by domain.
**Agent constraint — desktop router parity:** Edits to the desktop route tree must update **both**`src/spa/router/desktopRouter.config.tsx` and `src/spa/router/desktopRouter.config.desktop.tsx` in the same change (same paths, nesting, index routes, and segment registration). Updating only one causes drift; the missing tree can fail to register routes and surface as a **blank screen** or broken navigation on the affected build.
## When to Use This Skill
- Adding a new SPA route or route segment
- Defining or refactoring layout/page files under `src/routes/`
- Moving route-specific components or logic into `src/features/`
- Deciding where to put a new component (route folder vs feature folder)
| `_layout/index.tsx` or `layout.tsx` | Layout for this segment: wrap with `<Outlet />`, optional shell (e.g. sidebar + main). Should be thin: prefer re-exporting or composing from `@/features/*`. |
| `index.tsx` or `page.tsx` | Page entry for this segment. Only import from features and render; no business logic. |
| `[param]/index.tsx` (e.g. `[id]`, `[cronId]`) | Dynamic segment page. Same rule: thin, delegate to features. |
**Rule:** Route files should only **import and compose**. No new `features/` folders or heavy components inside `src/routes/`.
---
## 2. What Belongs in `src/features/`
Put **domain-oriented** UI and logic here:
- Layout building blocks: sidebars, headers, body panels, drawers
- Hooks and store usage for that domain
- Domain-specific forms, lists, modals, etc.
Organize by **domain** (e.g. `Pages`, `Home`, `Agent`, `PageEditor`), not by route path. One route can use several features; one feature can be used by several routes.
Each feature should:
- Live under `src/features/<FeatureName>/`
- Export a clear public API via `index.ts` or `index.tsx`
- Use `@/features/<FeatureName>/...` for internal imports when needed
---
## 3. How to Add a New SPA Route
1.**Choose the route group**
-`(main)/`– desktop main app
-`(mobile)/`– mobile
-`(desktop)/`– Electron-specific
-`onboarding/`, `share/`– special flows
2.**Create only segment files under `src/routes/`**
- e.g. `src/routes/(main)/my-feature/_layout/index.tsx` and `src/routes/(main)/my-feature/index.tsx` (and optional `[id]/index.tsx`).
3.**Implement layout and page content in `src/features/`**
- Create or reuse a domain (e.g. `src/features/MyFeature/`).
- Put layout (sidebar, header, body) and page UI there; export from the feature’s `index`.
4.**Keep route files thin**
- Layout: `export { default } from '@/features/MyFeature/MyLayout'` or compose a few feature components + `<Outlet />`.
- Page: import from `@/features/MyFeature` (or a specific subpath) and render; no business logic in the route file.
5.**Register the route (desktop — two files, always)**
- **`desktopRouter.config.tsx`:** Add the segment with `dynamicElement` / `dynamicLayout` pointing at route modules (e.g. `@/routes/(main)/my-feature`).
- **`desktopRouter.config.desktop.tsx`:** Mirror the **same**`RouteObject` shape: identical `path` / `index` / parent-child structure. Use the static imports and elements already used in that file (see neighboring routes). Do **not** register in only one of these files.
- **Mobile-only flows:** use `mobileRouter.config.tsx` instead (no need to duplicate into the desktop pair unless the route truly exists on both).
| `desktopRouter.config.tsx` | Dynamic imports via `dynamicElement` / `dynamicLayout` — code-splitting; used by `entry.web.tsx` and `entry.desktop.tsx`. |
| `desktopRouter.config.desktop.tsx` | Same route tree with **synchronous** imports — kept for Electron / local parity and predictable bundling. |
Anything that changes the tree (new segment, renamed `path`, moved layout, new child route) must be reflected in **both** files in one PR or commit. Remove routes from both when deleting.
---
## 4. How to Divide Files (route vs feature)
| Question | Put in `src/routes/` | Put in `src/features/` |
| Is it the route’s layout wrapper or page entry? | Yes –`_layout/index.tsx`, `index.tsx`, `[id]/index.tsx` | No |
| Does it contain business logic or non-trivial UI? | No | Yes – under the right domain |
| Is it a reusable layout piece (sidebar, header, body)? | No | Yes |
| Is it a hook, store usage, or domain logic? | No | Yes |
| Is it only re-exporting or composing feature components? | Yes | No |
**Examples**
- **Route (thin):**\
`src/routes/(main)/page/_layout/index.tsx` → `export { default } from '@/features/Pages/PageLayout'`
- **Feature (real implementation):**\
`src/features/Pages/PageLayout/` → Sidebar, DataSync, Body, Header, styles, etc.
- **Route (thin):**\
`src/routes/(main)/page/index.tsx` → Import `PageTitle`, `PageExplorerPlaceholder` from `@/features/Pages` and `@/features/PageExplorer`; render with `<PageTitle />` and placeholder.
- **Feature:**\
Page list, actions, drawers, and hooks live under `src/features/Pages/`.
---
## 5. Progressive Migration (existing code)
We are migrating existing routes to this structure step by step:
- **Phase 1 (done):** `/page` route – segment files in `src/routes/(main)/page/`, implementation in `src/features/Pages/`.
When touching an old route that still has logic or `features/` inside `src/routes/`:
1. Prefer adding **new** code in `src/features/<Domain>/` and importing from routes.
2. For larger refactors, move existing route-only logic into the right feature and then thin out the route files (re-export or compose from features).
3. Use `git mv` when moving files so history is preserved.
---
## 6. Reference Structure (after Phase 1)
**Route (thin):**
```
src/routes/(main)/page/
├── _layout/index.tsx → re-export or compose from @/features/Pages/PageLayout
├── index.tsx → import from @/features/Pages, @/features/PageExplorer
└── [id]/index.tsx → import from @/features/Pages, @/features/PageExplorer
```
**Feature (implementation):**
```
src/features/Pages/
├── index.ts → export PageLayout, PageTitle
├── PageTitle.tsx
└── PageLayout/
├── index.tsx → Sidebar + Outlet + DataSync
├── DataSync.tsx
├── Sidebar.tsx
├── style.ts
├── Body/ → list, actions, drawer, etc.
└── Header/ → breadcrumb, add button, etc.
```
Router config continues to point at **route** paths (e.g. `@/routes/(main)/page`, `@/routes/(main)/page/_layout`); route files then delegate to features.

---
# LobeHub Store Data Structures
This guide covers how to structure data in Zustand stores for optimal performance and user experience.
## Core Principles
### ✅ DO
1.**Separate List and Detail** - Use different structures for list pages and detail pages
2.**Use Map for Details** - Cache multiple detail pages with `Record<string, Detail>`
3.**Use Array for Lists** - Simple arrays for list display
4.**Types from @lobechat/types** - Never use `@lobechat/database` types in stores
5.**Distinguish List and Detail types** - List types may have computed UI fields
### ❌ DON'T
1.**Don't use single detail object** - Can't cache multiple pages
2.**Don't mix List and Detail types** - They have different purposes
3.**Don't use database types** - Use types from `@lobechat/types`
4.**Don't use Map for lists** - Simple arrays are sufficient
---
## Type Definitions
Types should be organized by entity in separate files:
```
@lobechat/types/src/eval/
├── benchmark.ts # Benchmark types
├── agentEvalDataset.ts # Dataset types
├── agentEvalRun.ts # Run types
└── index.ts # Re-exports
```
### Example: Benchmark Types
```typescript
// packages/types/src/eval/benchmark.ts
importtype{EvalBenchmarkRubric}from'./rubric';
// ============================================
// Detail Type - Full entity (for detail pages)
// ============================================
/**
* Full benchmark entity with all fields including heavy data
*/
exportinterfaceAgentEvalBenchmark{
createdAt: Date;
description?: string|null;
id: string;
identifier: string;
isSystem: boolean;
metadata?: Record<string,unknown>|null;
name: string;
referenceUrl?: string|null;
rubrics: EvalBenchmarkRubric[];// Heavy field
updatedAt: Date;
}
// ============================================
// List Type - Lightweight (for list display)
// ============================================
/**
* Lightweight benchmark item - excludes heavy fields
* May include computed statistics for UI
*/
exportinterfaceAgentEvalBenchmarkListItem{
createdAt: Date;
description?: string|null;
id: string;
identifier: string;
isSystem: boolean;
name: string;
// Note: rubrics NOT included (heavy field)
// Computed statistics for UI display
datasetCount?: number;
runCount?: number;
testCaseCount?: number;
}
```
### Example: Document Types (with heavy content)
```typescript
// packages/types/src/document.ts
/**
* Full document entity - includes heavy content fields
*/
exportinterfaceDocument{
id: string;
title: string;
description?: string;
content: string;// Heavy field - full markdown content
editorData: any;// Heavy field - editor state
metadata?: Record<string,unknown>;
createdAt: Date;
updatedAt: Date;
}
/**
* Lightweight document item - excludes heavy content
*/
exportinterfaceDocumentListItem{
id: string;
title: string;
description?: string;
// Note: content and editorData NOT included
createdAt: Date;
updatedAt: Date;
// Computed statistics
wordCount?: number;
lastEditedBy?: string;
}
```
**Key Points:**
- **Detail types** include ALL fields from database (full entity)
- **List types** are **subsets** that exclude heavy/large fields
- List types may add computed statistics for UI (e.g., `testCaseCount`)
- **Each entity gets its own file** (not mixed together)
- **All types** exported from `@lobechat/types`, NOT `@lobechat/database`
**Heavy fields to exclude from List:**
- Large text content (`content`, `editorData`, `fullDescription`)

---
# LobeHub Testing Guide
## Quick Reference
**Commands:**
```bash
# Run specific test file
bunx vitest run --silent='passed-only''[file-path]'
# Database package (client)
cd packages/database && bunx vitest run --silent='passed-only''[file]'
# Database package (server)
cd packages/database &&TEST_SERVER_DB=1 bunx vitest run --silent='passed-only''[file]'
```
**Never run**`bun run test` - it runs all 3000+ tests (\~10 minutes).
When tests fail due to implementation changes (not bugs), evaluate before blindly fixing:
### Keep & Fix (update test data/assertions)
- **Behavior tests**: Tests that verify _what_ the code does (output, side effects, user-visible behavior). Just update mock data formats or expected values.
- Example: Tool data structure changed from `{ name }` to `{ function: { name } }` → update mock data
- Example: Output format changed from `Current date: YYYY-MM-DD` to `Current date: YYYY-MM-DD (TZ)` → update expected string
### Delete (over-specified, low value)
- **Param-forwarding tests**: Tests that assert exact internal function call arguments (e.g., `expect(internalFn).toHaveBeenCalledWith(expect.objectContaining({ exact params }))`) — these break on every refactor and duplicate what behavior tests already cover.
- **Implementation-coupled tests**: Tests that verify _how_ the code works internally rather than _what_ it produces. If a higher-level test already covers the same behavior, the low-level test adds maintenance cost without coverage gain.
### Decision Checklist
1. Does the test verify **externally observable behavior** (API response, DB write, rendered output)? → **Keep**
2. Does the test only verify **internal wiring** (which function receives which params)? → Check if a behavior test already covers it. If yes → **Delete**
3. Is the same behavior already tested at a **higher integration level**? → Delete the lower-level duplicate
4. Would the test break again on the **next routine refactor**? → Consider raising to integration level or deleting
### When Writing New Tests
- Prefer **integration-level assertions** (verify final output) over **white-box assertions** (verify internal calls)
- Use `expect.objectContaining` only for stable, public-facing contracts — not for internal param shapes that change with refactors
- Mock at boundaries (DB, network, external services), not between internal modules
## Common Issues
1.**Module pollution**: Use `vi.resetModules()` when tests fail mysteriously
2.**Mock not working**: Check setup position and use `vi.clearAllMocks()` in beforeEach
3.**Test data pollution**: Clean database state in beforeEach/afterEach
4.**Async issues**: Wrap state changes in `act()` for React hooks
LobeHub Desktop uses Vitest as the test framework. Controller unit tests should be placed in the `__tests__` directory adjacent to the controller file, named with the original controller filename plus `.test.ts`.

# TypeScript Code Style Guide
## Types and Type Safety
- Avoid explicit type annotations when TypeScript can infer
- Avoid implicitly `any`; explicitly type when necessary
- Use accurate types: prefer `Record<PropertyKey, unknown>` over `object` or `any`
- Prefer `interface` for object shapes (e.g., React props); use `type` for unions/intersections
- Prefer `as const satisfies XyzInterface` over plain `as const`
- Prefer `@ts-expect-error` over `@ts-ignore` over `as any`
- Avoid meaningless null/undefined parameters; design strict function contracts
- Prefer ES module augmentation (`declare module '...'`) over `namespace`; do not introduce `namespace`-based extension patterns
- When a type needs extensibility, expose a small mergeable interface at the source type and let each feature/plugin augment it locally instead of centralizing all extension fields in one registry file
- For package-local extensibility patterns like `PipelineContext.metadata`, define the metadata fields next to the processor/provider/plugin that reads or writes them
## Async Patterns
- Prefer `async`/`await` over callbacks or `.then()` chains
- Prefer async APIs over sync ones (avoid `*Sync`)
- Use promise-based variants: `import { readFile } from 'fs/promises'`
- Use `Promise.all`, `Promise.race` for concurrent operations where safe
## Imports
- This project uses `simple-import-sort/imports` and `consistent-type-imports` (`fixStyle: 'separate-type-imports'`)
- **Separate type imports**: always use `import type { ... }` for type-only imports, NOT `import { type ... }` inline syntax
- When a file already has `import type { ... }` from a package and you need to add a value import, keep them as **two separate statements**:
```ts
import type { ChatTopicBotContext } from '@lobechat/types';
import { RequestTrigger } from '@lobechat/types';
```
- Within each import statement, specifiers are sorted **alphabetically by name**
## Code Structure
- Prefer object destructuring
- Use consistent, descriptive naming; avoid obscure abbreviations
- Replace magic numbers/strings with well-named constants
- Defer formatting to tooling
## UI and Theming
- Use `@lobehub/ui`, Ant Design components instead of raw HTML tags
- Design for dark mode and mobile responsiveness
- Use `antd-style` token system instead of hard-coded colors
## Performance
- Prefer `for…of` loops over index-based `for` loops
- Reuse existing utils in `packages/utils` or installed npm packages
- Query only required columns from database
## Time Consistency
- Assign `Date.now()` to a constant once and reuse for consistency
## Logging
- Never log user private information (API keys, etc.)
- Don't use `import { log } from 'debug'` directly (logs to console)
- Use `console.error` in catch blocks instead of debug package
- Always log the error in `.catch()` callbacks — silent `.catch(() => fallback)` swallows failures and makes debugging impossible
echo"export { POST } from 'lobehub/src/app/(backend)/api/workflows/feature-name/layer/route';" > lobehub-cloud/src/app/\(backend\)/api/workflows/feature-name/layer/route.ts
```
### Type Errors After Moving to Lobehub
**Cause**: Cloud-specific types or services used in lobehub code
**Solution**:
1. Extract cloud-specific logic to cloud-only wrapper
2. Use dependency injection for services
3. Define generic interfaces in lobehub

# Version Release Workflow
This skill is a router. The detailed steps live in `reference/`.
## Scope Boundary (Important)
This skill is only for:
1. Release branch / PR workflow
2. CI trigger constraints (`auto-tag-release.yml`)
3. GitHub Release note writing
This skill is **not** for writing `docs/changelog/*.mdx`.\
If the user asks for website changelog pages, load `../docs-changelog/SKILL.md`.
## Mandatory Companion Skill
For every `/version-release` execution, you MUST load and apply:
-`../microcopy/SKILL.md`
## Overview
The primary development branch is **canary**. All day-to-day development happens on canary. When releasing, canary is merged into main. After merge, `auto-tag-release.yml` automatically handles tagging, version bumping, creating a GitHub Release, and syncing back to the canary branch.
Only two release types are used in practice (major releases are extremely rare and can be ignored):
| Type | Use Case | Frequency | Source Branch | PR Title Format | Version | Reference |
| Patch | Weekly release / hotfix / model / DB migration | \~Weekly or as needed | canary or main | Custom (e.g. `🚀 release: 20260222`) | Auto patch +1 | `reference/patch-release-scenarios.md` |
For writing the release-note body (any release type), see `reference/release-notes-style.md`.
- **Patch release** (weekly / hotfix / model launch / DB migration) → `reference/patch-release-scenarios.md`
- **Writing the PR body / release notes** (any release type) → `reference/release-notes-style.md`
### Hard Rules (apply to every release type)
- **Do NOT** manually modify `package.json` version — CI handles it.
- **Do NOT** manually create tags — CI handles them.
- Minor PR title format is strict (`🚀 release: v{x.y.z}`).
- Patch PRs do not need an explicit version number.
- Keep release facts accurate; do not invent metrics or availability statements. Release-note inputs (compare base, PR refs, contributor list) **must be derived from `git`** per `reference/release-notes-style.md` § Computing Inputs — never from memory or descriptions.
**Migration Scope:** Agent benchmark data model bootstrap (5 new tables, 2 new indexes)
> This release introduces a schema foundation for benchmark execution and reporting, so agent evaluation data is stored as a complete lifecycle instead of fragmented records.
---
## 🗄️ Migration Overview
Added tables:
-`agent_eval_benchmarks`
-`agent_eval_datasets`
-`agent_eval_runs`
-`agent_eval_run_topics`
-`agent_eval_records`
Added indexes:
-`idx_agent_eval_runs_status_created_at`
-`idx_agent_eval_run_topics_run_id_topic_id`
These additions close a previous gap where benchmark data existed in partial forms but lacked a stable relational backbone for auditing and historical analysis.
---
## ⚙️ Operator Notes
- Migration runs automatically on application startup.
- No manual SQL is required in standard deployment paths.
- Schedule rollout in a low-traffic window and take a backup snapshot before deployment.
- If migration fails, do not retry repeatedly; inspect migration logs and lock state first.
---
## 🔒 Reliability & Risk
- Existing chat/session paths are unaffected unless benchmark features are enabled.
- Migration is additive (new tables/indexes only), minimizing downgrade risk to existing entities.
- Rollback should follow your standard DB restore or migration rollback policy if your environment requires strict reversibility.

**Hotfix Scope:** Agent topic-switching regression — stale chat state on agent change
> Clears residual topic state when navigating between agents and restores blank-canvas behavior on agent switch.
## 🐛 What's Fixed
- **Stale topic on agent switch** — Switching from `/agent/agt_A/tpc_X` to `/agent/agt_B` no longer leaves the previous topic's messages on screen, and _Start new topic_ responds again. (#14231)
- **Header & sidebar consistency** — Conversation header now shows the active subtopic's title, and the sidebar keeps the parent topic's thread list expanded while a thread is open.

## ✨ Highlights
- **Gateway Session Recovery** — Agent sessions now recover more reliably after short network interruptions, so long-running tasks continue with less manual retry. (#10121, #10133)
- **Fast Model Routing** — Expanded low-latency routing for priority model tiers, reducing wait time in high-frequency generation workflows. (#10102, #10117)

Used to publish a new minor version (e.g. `v2.2.0`), roughly every 4 weeks. The PR title carries the exact version number; CI parses it to drive the rest of the release.
## Steps
1.**Create a release branch from canary**
```bash
git checkout canary
git pull origin canary
git checkout -b release/v{version}
git push -u origin release/v{version}
```
2. **Determine the version number** — Read the current version from `package.json` and compute the next minor version (e.g. `2.1.x` → `2.2.0`).
3. **Create a PR to main**
```bash
gh pr create \
--title "🚀 release: v{version}" \
--base main \
--head release/v{version} \
--body-file release_body.md
```
> \[!IMPORTANT]
> The PR title must strictly match the `🚀 release: v{x.y.z}` format. CI uses a regex on this title to determine the exact version number.
4. **Write the PR body as release notes** — Follow `release-notes-style.md`. Compare base is the latest semver tag on main (`git describe --tags --abbrev=0 origin/main`).
5. **Automatic trigger after merge** — `auto-tag-release` detects the title format, uses the version number from the title, bumps `package.json`, tags `v{x.y.z}`, creates the GitHub Release, and dispatches `sync-main-to-canary`.
## Scripts
```bash
bun run release:branch # Interactive
bun run release:branch --minor # Directly specify minor
```
## Hard Rules (specific to Minor)
- PR title format is **strict**: `🚀 release: v{x.y.z}`. Any deviation falls through to patch detection.
- Do **NOT** manually modify `package.json` version — CI will bump it.
- Do **NOT** manually create the tag — CI will tag.
- Highlights bullet count is usually 8–12 (see `release-notes-style.md` size heuristics).
Then follow `./release-notes-style.md` § **Computing Inputs (Hard Rules)** to derive PR refs, metrics, and contributors. Every `(#XXXX)` in the body must come from actual commit subjects in this range — never inferred from descriptions.
3.**Create PR to main** with the changelog as the PR body
```bash
gh pr create \
--title "🚀 release: {YYYYMMDD}"\
--base main \
--head release/weekly-{YYYYMMDD}\
--body-file changelog.md
```
4.**After merge**: auto-tag-release detects `release/*` branch → auto patch +1.
---
## 2. Bug Hotfix
Emergency bug fix shipped directly from main.
### Steps
1.**Create hotfix branch from main**
```bash
git checkout main
git pull --rebase origin main
git checkout -b hotfix/v{version}-{short-hash}
git push -u origin hotfix/v{version}-{short-hash}
```
2.**Create PR to main** with a gitmoji prefix title (e.g. `🐛 fix: description`)
3.**Write a short hotfix changelog** — See `changelog-example/hotfix.md`. Keep it minimal: scope line, 1-3 fix bullets (symptom + fix in one sentence), upgrade note, owner. No long root-cause section — that lives in the commit message.
- **Hotfix owner**: Use the actual PR author (retrieve via `gh pr view <number> --json author --jq '.author.login'`), never hardcode a username.
4.**After merge**: auto-tag-release detects `hotfix/*` branch → auto patch +1.
### Script
```bash
bun run hotfix:branch
```
---
## 3. New Model Launch
New AI model or provider support, typically contributed via community PRs.
### How it works
- Community contributors submit PRs with titles like `✨ feat: add xxx model` or `💄 style: support xxx models`
- These PR title prefixes (`feat` / `style`) are in the auto-tag trigger list
- No special branch naming or manual release steps required — merging the PR triggers auto patch +1
### When Claude is involved
If asked to add model support, just create a normal feature PR. The title prefix will trigger the release automatically.
---
## 4. DB Schema Migration
Database schema changes that need to be released independently. These require a dedicated changelog explaining the migration for self-hosted users.
### Steps
1.**Create release branch from main and cherry-pick migration commits**
```bash
git checkout main
git pull --rebase origin main
git checkout -b release/db-migration-{name}
git cherry-pick <migration-commit-hash>
git push -u origin release/db-migration-{name}
```
2.**Write a migration-specific changelog** — See `db-migration-changelog-example.md` for the format. This should explain:
- What tables/columns are added, modified, or removed
- Whether the migration is backwards-compatible
- Any action required by self-hosted users
- **Migration owner**: Use the actual PR author (retrieve via `gh pr view <number> --json author --jq '.author.login'` or `git log` commit author), never hardcode a username
3.**Create PR to main** with the migration changelog as the PR body
```bash
gh pr create \
--title "👷 build: {migration description}"\
--base main \
--head release/db-migration-{name}\
--body-file changelog.md
```
4.**After merge**: auto-tag-release detects `release/*` branch → auto patch +1.
# GitHub Release Changelog Standard (Long-Form Style)
Use this guide for **GitHub Release notes** — the body of a release PR that becomes the GitHub Release after merge. Do **not** use it for `docs/changelog/*.mdx` website pages (load `../../docs-changelog/SKILL.md` instead).
## Positioning
This release-note style is:
1.**Data-backed at the top** (date, range, key metrics)
2.**Narrative first, then structured detail**
3.**Deep but scannable** (clear sectioning + compact bullets)
4.**Contributor-forward** (credits are part of the release story)
4. Contributor list (with standout contributions if known)
5. Known risks / migrations / rollout notes (if any)
If metrics cannot be reliably computed, omit unknown numbers instead of guessing.
## Computing Inputs (Hard Rules — Verify, Never Guess)
> Hallucinated PR numbers and wrong "Since v..." bases are the #1 failure mode of this skill. Every number and every `(#XXXX)` must come from `git`, never from memory or inference.
### 1. Compare base = latest semver tag on `main`
Do **not** eyeball the tag list or pick the "last weekly" PR. Compute it:
Sanity check that the tag is reachable from the release branch:
```bash
git merge-base --is-ancestor "$PREV_TAG" origin/release/weekly-{YYYYMMDD}&&echo OK
```
If the check fails, stop and ask the user — the release branch is based on the wrong source.
> **Why not "the last weekly release PR"?** Hotfixes (`v2.1.54`, `v2.1.55`, …) merge directly into main between weeklies. They get back-merged via `sync-main-to-canary`, so the latest semver tag on main _is_ the correct previous release for both weekly and minor flows. Picking the previous weekly's tag will silently undercount and put a stale version in "Since v…".
### 2. PR refs must come from commit subjects — never from descriptions
- Every `(#XXXX)` you write in the body **must** appear in `/tmp/release_prs.txt`. No exceptions.
- Never infer a PR number from a feature description. If you remember "the KB BM25 PR was around #14501", that memory is wrong about half the time. Look up the commit hash by feature keyword and read its actual subject.
- If your terminal truncates long subjects (any wrapper that compresses output, e.g. `rtk`), bypass it. With `rtk` use `rtk proxy git log …`. Verify with `wc -l /tmp/release_prs.txt` — the count must match `git log $PREV_TAG..HEAD --no-merges --pretty=format:'%h' | wc -l` minus the few commits without a PR ref. A mismatch of >5% means subjects are being silently truncated.
sed 's/[()]//g' /tmp/release_prs.txt > /tmp/release_prs_clean.txt
echo"=== In body but NOT in actual range (must be EMPTY) ==="
comm -23 /tmp/body_prs.txt /tmp/release_prs_clean.txt
```
Empty diff = OK. Any output = the body cites a PR that wasn't merged in this range. Stop and fix before publishing.
Also verify the metrics line in the body matches the computed values (`PR_COUNT`, `CONTRIBUTOR_COUNT`) and that `**Full Changelog**` uses `$PREV_TAG`, not some older tag.
## Canonical Structure (Long-Form: Minor / Weekly)
Follow this section order for **Minor** and **Weekly** releases unless the user asks otherwise. For **Hotfix** and **DB Migration**, see § Variants for Shorter Releases below — the canonical structure does not apply.
1.`# 🚀 LobeHub Release (<YYYYMMDD>)`
2. Metadata lines:
-`Release Date`
-`Since <Previous Version>` metrics
3. One quoted release thesis (single paragraph, 1-2 lines)
4.`## ✨ Highlights` (6-12 bullets for major releases; 3-8 for weekly)
Use `---` separators between major blocks for long releases.
## Variants for Shorter Releases
The Canonical Structure above is for **long-form** (Minor / Weekly). Two short-form variants override it.
### Hotfix Variant
A hotfix targets one regression and ships fast. The body is short and operator-focused — no Highlights, no domain blocks, no Contributors line.
Required sections, in order:
1.`# 🚀 LobeHub Release (<YYYYMMDD>)`
2.`**Hotfix Scope:**` — one line summarizing the regression scope (e.g. `Agent topic-switching regression — stale chat state on agent change`). Replaces the long-form `Release Date` / `Since vX.Y.Z` metrics.
3. One quoted thesis (single paragraph, 1-2 lines) describing what is now restored.
4.`## 🐛 What's Fixed` — 1-3 bullets, each `**<symptom>** — <fix in one sentence>. (#PR)`. No root-cause prose; that lives in the commit message.
5.`## ⚙️ Upgrade` — short notes for self-hosted (pull image / restart, schema or env changes) and cloud (usually "applied automatically").
6.`## 👥 Owner` — single `@handle` for the PR author, resolved via `gh pr view "$PR" --json author --jq '.author.login'`. Never hardcoded.
Hard rules specific to hotfix:
- **No Highlights / domain blocks / Contributors / Full Changelog** — these add noise to a one-shot fix.
- **No metric line** — `Since vX.Y.Z` doesn't apply; the body cites the single PR (or 1-3 PRs) directly.
- **Owner ≠ Contributors** — one author, listed under § Owner. Not a flat handle list.
- See `changelog-example/hotfix.md` for the canonical template.
### DB Migration Variant
Database schema changes that need to be released independently. Operator impact is the headline.
Required sections, in order:
1.`# 🚀 LobeHub Release (<YYYYMMDD>)` + scope line
2.**Migration overview** — what tables / columns are added, modified, or removed
3.**Operator impact** — backwards-compatible? required actions for self-hosted?
4.**Rollback / backup note** — how to recover
5.`## 👥 Owner` — single PR author, resolved via `gh pr view`
See `changelog-example/db-migration.md` for the canonical template.
## Writing Rules (Hard)
1.**No fabricated metrics**: all numbers must be traceable.
2.**No vague headline bullets**: each bullet must include capability + impact.
3.**No internal-only framing**: phrase from user/operator perspective.
4.**Security must be explicit** when security-sensitive fixes are present.
5.**PR/issue linkage**: use `(#1234)` when IDs are available.
6.**Terminology consistency**: same feature/provider name across sections.
7.**Do not bury migration or breaking changes**: elevate to dedicated section or callout.
## Style Rules (Long-Form)
1. Start with an "everyday use" framing, not implementation internals.
2. Mix narrative sentence + evidence bullets.
3. Keep bullets compact but informative:
- Good: `**Fast Mode (`/fast`)** — Priority routing for OpenAI and Anthropic, reducing latency on supported models. (#6875, #6960)`
4. Use bold only for capability names, not for whole sentences.
5. Keep heading depth ≤ 3 levels.
## Release Size Heuristics
- **Minor / major milestone release**
- Long-form structure with multiple domain blocks.
-`Highlights` usually 8-12 bullets.
- **Weekly patch release**
- Long-form skeleton with reduced subsection count.
-`Highlights` usually 4-8 bullets.
- **Hotfix release**
- Short-form (see § Variants → Hotfix). No Highlights, no domain blocks, no Contributors.
- 1-3 fix bullets. Body should fit on one screen.
- **DB migration release**
- Short-form (see § Variants → DB Migration).
- Must include `Migration overview`, operator impact, and rollback/backup note.
## Contributor Ordering
Render contributors as a **single flat list** (no separate "Community" / "Core Team" subsections). Order: **community contributors first, team members after**. Within each group, sort by PR count desc. Bots (`@lobehubbot`, `renovate[bot]`) go on a separate "maintenance" line.
**LobeHub team roster** — anyone in this list is a team member; anyone not in this list is a community contributor:
-@arvinxx
-@Innei
-@tjx666 (commit author name: YuTengjing)
-@LiJian
-@Neko
-@Rdmclin2
-@AmAzing129
-@sudongyuer (commit author name: Tsuki)
-@rivertwilight (commit author name: René Wang)
-@CanisMinor
-@cy948 (commit author name: Rylan Cai)
> **Resolving handles** — git author names (e.g. `YuTengjing`) are not always the GitHub handle. Verify via `gh pr view "$PR" --json author` or `gh api search/users -f q='<email>'` before listing.
If a new contributor appears who is not on this list, treat them as community by default and ask the user whether to add them to the roster.

1.**List in-flight PRs**:
```bash
gh pr list --search "automatic/add-tests-" --state open --json number,title,headRefName,mergeable
```
2. **Close conflicting PRs**: For any PR where `mergeable` is `"CONFLICTING"`, close it with a comment:
```bash
gh pr close <number> --comment "Closing: this PR has merge conflicts with main and is outdated. A new test PR may be created for this module."

You are a support assistant for LobeChat authentication migration issues. Your job is to help users who are migrating from NextAuth or Clerk to Better Auth.
**IMPORTANT**: The official documentation website is `https://lobehub.com`. When providing documentation links, always use `https://lobehub.com/docs/...` format. Never use `lobechat.com` - that domain is incorrect.
If you detect any leaked secrets, respond IMMEDIATELY with:
```markdown
@username
⚠️ **Security Warning**: Your comment appears to contain sensitive information (API keys, secrets, or credentials).
**Please delete your comment immediately** to protect your account security, then:
1. Rotate/regenerate any exposed credentials
2. Re-post your question with secrets redacted (e.g., `AUTH_SECRET=***`)
I will not process this request until the sensitive information is removed.
```
Do NOT process the rest of the comment if secrets are detected.
## Step 2: Handle Success Feedback
If the user's comment indicates their issue is resolved or deployment succeeded (e.g., "solved", "fixed", "working now", "thanks", "problem resolved", "successfully deployed"):
1. Create a marker file to trigger auto-hide:
```bash
echo"HIDE_COMMENT=true" >> /tmp/claude-output
```
2. Do NOT post any reply - just create the marker file and stop processing.
## Step 3: Check Required Information
Read the issue description to see what information users should provide:
```bash
gh issue view [ISSUE_NUMBER] --json body -q '.body'
```
Check the "How to Reporting Issues" section in the issue description for required information. If the user's comment is missing any required items, politely ask them to provide it.
## Step 4: Common Issues and Solutions
Look for the "Troubleshooting" or "FAQ" section in the migration docs and match the user's issue against documented solutions. If a solution exists, provide it with a link to the documentation.
## Response Guidelines
1.**Be helpful and friendly** - Users are often frustrated when migration doesn't work
2.**Be specific** - Provide exact commands or configuration examples
3.**Reference documentation** - Point users to relevant docs sections
4.**Ask for logs** - If the issue is unclear, ask for Docker logs:
```bash
docker logs <container_name> 2>&1 | tail -100
```
5. **One issue at a time** - Focus on solving one problem before moving to the next
