Sai Karthik 7f366eab84 cmd: add --no-skills, --skill, and --skills-dir CLI flags & config (#55)
* cmd: add --no-skills, --skill, and --skills-dir CLI flags

The pkg/kit Options struct already had full backend support for skills
control (NoSkills, Skills []string, SkillsDir) wired into loadSkills()
in pkg/kit/kit.go, but there were no corresponding CLI flags to drive
them. This commit closes that gap.

Changes in cmd/root.go:

- Add three package-level flag variables alongside the existing
  noExtensionsFlag/extensionPaths group:
    noSkillsFlag bool
    skillsPaths  []string
    skillsDir    string

- Register three persistent cobra flags in init():
    --no-skills        disable skill loading (auto-discovery and explicit)
    --skill <path>     load a skill file or directory (repeatable)
    --skills-dir <dir> override the project-local skills directory
                       used for auto-discovery

- Wire all three into the kitOpts struct literal in runNormalMode()
  so they flow directly into kit.New() -> loadSkills().

No changes to pkg/kit or internal/skills -- the backend was already
complete. No viper binding is needed because kit.go reads these fields
directly from opts rather than from viper (unlike NoExtensions which
uses the viper fallback path).

Example usage:
  kit --no-skills "prompt"
  kit --skill ./my-skill.md --skill ./other-skill.md "prompt"
  kit --skills-dir /path/to/skills "prompt"

* docs: document --no-skills, --skill, and --skills-dir CLI flags

Add the three new skills CLI flags to all relevant documentation:

- README.md: add Skills section under Global Flags CLI reference
- www/pages/cli/flags.md: add Skills table (mirrors Extensions section pattern)
- www/pages/cli/commands.md: expand the Skills section with usage examples
  and a description of auto-discovery vs explicit loading vs --no-skills

* feat: add config file support for skills options

Skills could previously only be controlled via CLI flags or SDK Options
fields. This commit wires all three skills settings into viper so they
can also be set in .kit.yml / .kit.yaml / .kit.json and via KIT_*
environment variables — matching the pattern used by no-extensions,
no-core-tools, and prompt-template.

cmd/root.go:
- Bind --no-skills, --skill, and --skills-dir flags to viper keys
  (no-skills, skill, skills-dir) so config file values flow through.

pkg/kit/kit.go:
- At skill-load time, merge opts fields with viper values:
  - noSkills = opts.NoSkills || v.GetBool("no-skills")
  - skillPaths: opts.Skills if non-empty, else v.GetStringSlice("skill")
  - skillsDir: opts.SkillsDir if non-empty, else v.GetString("skills-dir")
- Build a shallow-copied mergedOpts so loadSkills() picks up the
  resolved values without mutating the original Options struct.

docs:
- README.md: add skills keys to the Basic Configuration YAML example
- www/pages/configuration.md: add no-skills, skill, skills-dir rows to
  the All configuration keys table

Config file example (.kit.yml):
  no-skills: false
  skill:
    - /path/to/skill.md
  skills-dir: /path/to/skills/

* config: add skills keys to default .kit.yml template

Add no-skills, skill, and skills-dir as commented-out examples in the
default config file generated by EnsureConfigExists(), alongside the
existing application settings block.

Co-authored-by: Claude <claude@anthropic.com>

* test: add test coverage for skills CLI flags and config keys

Four test locations updated:

pkg/kit/export_test.go:
- Add ConfigStringSliceForTest() helper to expose v.GetStringSlice()
  from the Kit's isolated viper store, needed to assert skill list values.

pkg/kit/kit_test.go (TestNewWithSkillsOptions):
- NoSkills=true: GetSkills() returns empty slice
- SkillsDir=<empty dir>: kit.New() succeeds with zero skills
- Skills=[file]: single explicit skill file is loaded and name parsed correctly

pkg/kit/viper_isolation_test.go:
- TestSkillsViperKeys: no-API-key struct-level checks for NoSkills, Skills,
  and SkillsDir fields on Options
- TestSkillsConfigFileKeys: full kit.New() round-trips via a written .kit.yml
  for each of the three config keys:
    no-skills: true  → GetSkills() returns empty
    skill: [path]    → named skill loaded from config file path
    skills-dir: dir  → custom discovery root accepted without error

internal/config/config_test.go (TestEnsureConfigExists):
- Assert generated ~/.kit.yml template contains '# Skills configuration',
  'no-skills:', and 'skills-dir:' comment blocks.

Ed Zynda 49f8b485be feat(extensions): add OnLLMUsage, SetState, enriched AgentEndEvent (#53) (#54)
* feat(extensions): add OnLLMUsage, SetState, enriched AgentEndEvent (#53)

Three additive primitives to the extension API:

- OnLLMUsage event: per-LLM-call token + cost deltas attributed to the
  specific model/provider used for each round-trip. Derived from the SDK
  StepFinishEvent in the extension bridge. Enables accurate budget
  enforcement between calls instead of only at turn boundaries.

- ctx.SetState / GetState / DeleteState / ListState: session-scoped,
  last-write-wins key-value store backed by a sidecar file
  (<session>.ext-state.json) outside the conversation tree. Reads are
  O(1), writes don't grow the JSONL, and the store is not duplicated on
  fork. State is preserved across hot-reloads.

- Enriched AgentEndEvent: ToolCallCount, ToolNames, LLMCallCount, token
  deltas (input/output/cache-read/cache-write), CostDelta, and
  DurationMs populated by a per-turn aggregator. Existing handlers
  reading only Response/StopReason are unaffected.

Includes unit tests for the state store, LLMUsage registration,
enriched AgentEndEvent, turn aggregator, llmUsageMeta, and sidecar path
derivation. Adds examples/extensions/usage-budget.go demoing all three
primitives together. Documents the additions in README, the docs site
(extensions overview, capabilities, examples), and the kit-extensions
and kit-sdk skill guides.

Fixes #53

* fix(extensions): address review feedback on state store and llmUsageMeta

- Serialize SetState/DeleteState saver invocations through a new saverMu
  so overlapping atomic-rename writes can no longer race on the shared
  .tmp file and persist an older snapshot after a newer one.
- LoadStateFromFile now clears the in-memory store when the sidecar is
  missing or empty, matching the documented "replace … with its
  contents" contract. This makes session-switching safe by preventing
  keys from a prior session leaking into a new one. Tests updated to
  cover both the missing-file and empty-file cases.
- llmUsageMeta now detects Anthropic OAuth credentials and returns
  Cost=0, matching the comment and the existing usage_tracker behavior
  for OAuth users. Mirrors the OAuth detection already used in
  cmd/extension_context.go.
- Document the single-in-flight-turn assumption baked into the
  per-turn aggregator with a clear migration path (per-turn ID) for if
  concurrent turns ever become a supported use case.

* fix(extensions): release saverMu on panic in state store

Extract a runSaver helper that locks saverMu and defers Unlock before
invoking the persistence callback. Without the deferred Unlock, a panic
inside the saver (e.g. disk full mid-write) would leave saverMu held
forever and deadlock the next SetState/DeleteState. Both SetState and
DeleteState now route through the helper. New TestRunner_State_Saver
PanicReleasesSaverMu reproduces the deadlock window with a 2s deadline
and proves the mutex is released after a panic.

Ed Zynda d27022bcfb feat(ui): render half-block thumbnails for attached images (#47)
* feat(ui): render half-block thumbnails for attached images (#46)

- Add internal/ui/imagepreview package: Render() draws low-res
  thumbnails using Unicode half-blocks (▀) + truecolor/256-color SGR,
  which survives tmux/zellij (no graphics protocol)
- Cache a rendered thumbnail per pending clipboard image in the input
  component; render once at attach time, never per frame
- Fall back to the existing [N image(s) attached] text pill when the
  terminal lacks truecolor/256-color support
- Document Ctrl+V paste, Ctrl+U clear, and the preview in the docs
  site and README keyboard shortcuts

Fixes #46

* fix(ui): render image thumbnails off the event loop and cap size

- Render thumbnails asynchronously via a tea.Cmd instead of calling
  the decode + resample path synchronously inside Update(), which
  blocked the Bubble Tea event loop
- Add thumbnailReadyMsg + an imageGen generation counter so async
  results land on the correct pendingImages slot and stale renders
  after a clear/re-attach are discarded
- Guard imagepreview.Render against decompression bombs by checking
  DecodeConfig dimensions against a max before full decode

* fix(ui): skip image preview when input width is too small

- Return 0 from thumbCols when width <= 6 so a full-size thumbnail is
  no longer rendered for tiny or uninitialized (width 0) terminals;
  the caller falls back to the text pill

Ed Zynda ae722d520f fix(models): route auto-discovered providers by wire protocol (#41) (#43)
- replace npmToLLMProvider map with npmToWireProtocol (openai/anthropic/google)
- add createAutoRoutedGoogleProvider so @ai-sdk/google proxies work
  (fixes opencode/gemini-* failing with "no LLM provider mapping")
- strip the genai-injected v1beta segment for proxies whose base URL
  already carries a version (e.g. opencode's /zen/v1)
- preserve openai-compat fallback and clearer error for unroutable providers
- document auto-routing in README and providers docs; update CreateProvider godoc
- add regression tests for wire routing and version-path rewriting

Ed Zynda 7a04bdfeba feat(kit): isolate viper config per Kit instance + add NewAgent (#42)
* feat(kit): isolate viper config per Kit instance + add NewAgent (#40)

- Give each kit.New()/NewAgent() call an isolated *viper.Viper store so
  multiple Kit instances in one process no longer clobber each other's
  config; runtime mutators (SetModel, SetThinkingLevel) touch only the
  owning instance, making subagent spawning and multi-Kit embedding
  race-free
- Thread the per-instance store through internal/config, internal/models
  (ProviderConfig.ConfigStore), internal/kitsetup, and the extension
  runner, with a nil -> process-global fallback so the CLI is unaffected
- Share the global store when Options.CLI != nil to preserve cobra flag
  bindings (also opted in for internal/acpserver)
- Remove viperInitMu; preserve the tri-state IsSet precedence contract
  and sdkDefaultMaxTokens floor
- Add ergonomic NewAgent + functional options (WithModel, WithStreaming,
  Ephemeral, etc.); NewAgent defaults streaming on, opt out via
  WithStreaming(false). New(ctx, *Options) behavior is unchanged
- Add config-isolation regression test and NewAgent/option coverage;
  document NewAgent and per-instance isolation in README

Fixes #40

* docs(sdk): document NewAgent options and per-instance config isolation

- Add "Functional options (NewAgent)" and "Per-instance config isolation"
  sections to the docs site SDK overview, with an options table and a
  "when to use which" constructor comparison
- Cross-reference NewAgent from the SDK options page and correct the now
  per-instance ProviderAPIKey precedence wording
- Document NewAgent + With* helpers and config isolation in pkg/kit/README
  and list NewAgent/Option in the API reference
- Show the NewAgent constructor in the SDK examples getting-started snippet

* fix(kit): correct config loading and isolate ACP sessions

- Isolate each ACP session's config store instead of sharing the global
  viper, preventing per-session SetModel/SetThinkingLevel races; seed the
  root-command flag values (model, thinking-level, provider URL/key) so
  `kit acp -m <model>` is still honored
- Run initConfig for isolated SDK stores by gating on opts.CLI instead of
  v.GetString("model"), which setSDKDefaults always populates and thus
  skipped .kit.yml / KIT_* loading for SDK callers
- Configure KIT_* env overrides unconditionally in initConfig so passing an
  explicit config file no longer disables environment variable support
- Wrap config unmarshal/validate errors with %w to preserve the error chain

* fix(kit): make Options.Streaming a *bool to honor unset

- Change Options.Streaming from bool to *bool so a zero-valued Options no
  longer forces stream=false; New only sets the key when non-nil, letting
  streaming resolve through the precedence chain (env -> config -> default
  true). This also fixes the CLI path, which never set the field
- Mirror the existing sampling-parameter pointer pattern instead of adding
  a separate StreamingSet sentinel, keeping Options internally consistent
- Update WithStreaming/NewAgent, subagent, and ACP callers to the pointer
  form; add regression tests for the nil-default and explicit opt-out paths
- Update SDK docs (README, pkg/kit/README, options page) with the ptrBool
  helper and *bool semantics

* fix(kit): inherit parent provider config in subagents

- Copy the parent's effective provider/runtime config (API key, URL,
  TLS, thinking level, max-tokens, samplers) onto child Options in
  Kit.Subagent. After the per-instance viper isolation, the child's
  isolated store only re-loaded .kit.yml / KIT_*, silently dropping
  config the parent set via programmatic Options or runtime setters
  like SetThinkingLevel
- Preserve the IsSet tri-state for max-tokens and samplers so per-model
  defaults still apply on the child when the parent left them unset
- Add TestInheritProviderConfig covering propagation, unset keys, and
  nil-safety

Sai Karthik 1e12102b92 CLI & Config changes to support disabling core tools (#35)
* feat(core): expose no-core-tools via CLI flag and config file

Allow users to disable all built-in core tools (bash, read, write,
edit, grep, find, ls, subagent) without recompiling, using a CLI flag,
environment variable, or .kit.yml config key.

Changes
-------
cmd/root.go
  - Declare noCoreToolsFlag bool alongside noExtensionsFlag.
  - Register --no-core-tools persistent flag with a descriptive help string
    listing the affected tools.
  - Bind the flag to viper key "no-core-tools" so the config file and
    KIT_NO_CORE_TOOLS env var also work (viper's standard precedence:
    CLI flag > env var > config file > default).
  - Set kitOpts.DisableCoreTools = viper.GetBool("no-core-tools") when
    assembling the Options struct in runNormalMode.

pkg/kit/kit.go
  - Add disableCoreTools local variable inside the viperInitMu-protected
    snapshot block, mirroring the noExtensions pattern exactly.
  - Resolve it as opts.DisableCoreTools || viper.GetBool("no-core-tools")
    so the SDK option and the viper key are both respected (OR semantics:
    either source can enable the flag).
  - Pass the resolved disableCoreTools into kitsetup.AgentSetupOptions
    instead of the raw opts.DisableCoreTools, completing the chain.

Usage
-----
  # CLI flag
  kit --no-core-tools

  # Environment variable
  KIT_NO_CORE_TOOLS=true kit

  # .kit.yml config file
  no-core-tools: true

  # SDK (unchanged, was already supported)
  kit.New(ctx, &kit.Options{DisableCoreTools: true})

The downstream path (kitsetup → agent.AgentConfig.DisableCoreTools →
agent.NewAgent nil-tool branch) was already in place and required no
changes.

* docs(readme): document no-core-tools flag, config key, and env var

Update three locations in README.md to reflect the new no-core-tools
control surface introduced in the previous commit:

CLI Reference → Global Flags
  Add --no-core-tools under the Extensions and tools section alongside
  --no-extensions, with a description listing the affected tools.

Configuration → Basic Configuration
  Add no-core-tools: false to the example .kit.yml block so users know
  it is a valid config file key (equivalent to the CLI flag and env var).

Go SDK → With Options
  Expand the DisableCoreTools comment to note that the same behaviour is
  also available via --no-core-tools, KIT_NO_CORE_TOOLS, and
  no-core-tools: true in .kit.yml, making the cross-surface relationship
  explicit for SDK consumers.

Ed Zynda ab2a77c95e feat(sdk): runtime skills and context-file management (#36) (#37)
* feat(sdk): runtime skills and context-file management (#36)

Let SDK consumers add, remove, and replace skills and AGENTS.md-style
context files after Kit construction. Every mutation recomposes the
system prompt and applies it to the agent so the next turn picks up
the new instructions without restarting Kit.

- AddSkill / LoadAndAddSkill / RemoveSkill / SetSkills on *kit.Kit
- AddContextFile / AddContextFileContent / LoadAndAddContextFile /
  RemoveContextFile / SetContextFiles on *kit.Kit
- RefreshSystemPrompt to force a manual recomposition
- agent.SetSystemPrompt / GetSystemPrompt on the internal agent so
  the composed prompt rebuilds the fantasy agent on the next call
- Per-instance runtimeMu guards skills/contextFiles; GetSkills and
  GetContextFiles return defensive snapshots safe for concurrent use
- Capture the resolved basePrompt during New so recomposition keeps
  per-model overrides and --system-prompt file resolution intact
- Skills dedupe by Name; context files dedupe by Path (opaque ID,
  not required to be a real filesystem path)

Tests cover add/remove/set/replace semantics, validation errors,
disk loading round-trips, prompt composition, and an 8-goroutine
race-stress sweep (go test -race clean).

Docs: pkg/kit/README, root README Go SDK section, www sdk/overview
"Runtime skills and context files" section, www sdk/options callout
cross-referencing the new API.

Fixes #36

* fix(agent): synchronize SetSystemPrompt against concurrent rebuilds

- add promptMu to Agent guarding systemPrompt writes and the fantasy
  agent rebuild, fixing a data race when Kit.applyComposedSystemPrompt
  is invoked concurrently
- read systemPrompt under the same lock in GetSystemPrompt
- update the thread-safety stress test to use a non-nil agent so the
  SetSystemPrompt path is actually exercised under -race

  custom) and linking to the full options docs.
- pkg/kit/README.md: type cheat-sheet now lists MCPAuthHandler,
  DefaultMCPAuthHandler, and CLIMCPAuthHandler alongside the existing
  MCPTokenStore entries.
- skills/kit-sdk/SKILL.md: Options example annotated with nil-disables-
  OAuth semantics; new 'MCP OAuth Authorization' section precedes the
  existing token-storage section; re-exported types list expanded.
- www/pages/sdk/options.md: Options fields table gains MCPAuthHandler
  row; new top-level 'MCP OAuth Authorization' section with consumer
  matrix, CLI/custom/fully-custom code samples, and a warning callout
  about the OnAuthURL nil-hang footgun.

Ed Zynda e1c94cb362 fix(sdk): align SDK max-tokens floor with CLI default (4096 → 8192)
The SDK last-resort MaxTokens floor is applied in kit.New() when
Options.MaxTokens, KIT_MAX_TOKENS, .kit.yml, and per-model defaults
are all unset. It was 4096 (inherited from the old setSDKDefaults
viper default) while the CLI --max-tokens cobra default is 8192.

Bump the floor to 8192 so SDK and CLI callers start from the same
base value before rightSizeMaxTokens runs, then update README,
skills/kit-sdk/SKILL.md, and www/pages/{configuration,sdk/options}.md
to match.
2026-04-17 11:59:49 +03:00
Ed Zynda ecf95b52e1 fix(sdk): preserve IsSet semantics for generation param overrides
Previously setSDKDefaults() registered viper.SetDefault for max-tokens,
temperature, top-p, top-k, frequency/presence-penalty, and thinking-level.
viper.SetDefault makes IsSet() return true, which silently suppressed
per-model defaults (ApplyModelSettings) and automatic right-sizing
(rightSizeMaxTokens) for every SDK-created Kit — and for CLI runs too,
since cmd/root.go routes through kit.New. Effective max-tokens for
claude-sonnet-4-5 was pinned at 4096 instead of 32768.

- Drop SetDefault for all IsSet-sensitive keys; keep only model,
  system-prompt, stream, num-gpu-layers, main-gpu.
- Apply a 4096 max-tokens floor directly on the *models.ProviderConfig
  struct in kit.New() when nothing else resolved a value. Keeps
  viper.IsSet("max-tokens") == false so rightSizeMaxTokens and
  per-model maxTokens overrides still fire.
- Update Options.MaxTokens / ThinkingLevel godoc to describe the real
  precedence chain.
- Strengthen tests: add Temperature subtest; add
  TestNewPreservesIsSetSemantics regression covering all seven keys;
  split TestNewWithProviderOptions into three subtests including
  Options-beats-viper-state and ProviderURL propagation; add
  resetViper helper so subtests don't bleed state.
- Document the new SDK fields (MaxTokens, ThinkingLevel, Temperature,
  TopP, TopK, FrequencyPenalty, PresencePenalty, ProviderAPIKey,
  ProviderURL, TLSSkipVerify) in README, skills/kit-sdk, and the www
  configuration / sdk/options / sdk/overview pages, including a
  dedicated precedence table.

Ed Zynda 3ffc995f27 feat(sdk): add NewTool/NewParallelTool for dependency-free custom tools
- Add ToolOutput struct, TextResult/ErrorResult helpers, and
  ToolCallIDFromContext so SDK consumers can create custom tools
  without importing charm.land/fantasy

  constructors with automatic JSON schema generation from struct tags
- Remove dead UpdateUsageFromResponse method and fantasy import from
  internal/ui/cli.go

  and corrected hook signatures
2026-04-07 22:05:42 +03:00
Ed Zynda f65b6737f2 feat(sdk): add SkipConfig and DisableCoreTools options
Add two new Options fields for programmatic SDK usage:

- SkipConfig: Skip .kit.yml file loading while still using viper defaults
  and environment variables. Useful for fully programmatic configuration.

- DisableCoreTools: Allow creating agents with 0 tools (chat-only mode) or
  with only custom tools. When true and Tools is empty, no tools are loaded.
  When combined with custom Tools, only those tools are loaded.

Updates documentation in README, pkg/kit/README, skills/kit-sdk/SKILL,
and www/pages/sdk/options.

Ed Zynda 4e7d823ee4 feat(ui): make /fork create new session file matching Pi behavior
- Add ForkToNewSession method to create new session with history up to target
- Add NewTreeSelectorForFork showing only user messages (flat list)
- Update performFork to create and switch to new session file
- Update /fork command description in docs and help text

Previously /fork just branched within the same session file like /tree.
Now /fork creates a completely new session file with parent_session reference,
matching Pi's behavior exactly.

Ed Zynda f0e4e2f757 refactor: remove Fantasy dependency name leakage from public SDK and docs
Rename public SDK symbols to use generic LLM terminology instead of
exposing the internal dependency name (charm.land/fantasy):

Public API renames (with deprecated wrappers for backward compat):
- ConvertToFantasyMessages() → ConvertToLLMMessages()
- ConvertFromFantasyMessage() → ConvertFromLLMMessage()
- GetFantasyProviders() → GetLLMProviders()

New type alias:
- LLMFilePart = fantasy.FilePart (eliminates need for direct fantasy import)
- PromptResultWithFiles() signature now uses LLMFilePart

Internal renames (with deprecated wrappers):
- ModelsRegistry.GetFantasyProviders() → GetLLMProviders()
- TreeManager.GetFantasyMessages() → GetLLMMessages()
- TreeManager.AppendFantasyMessage() → AppendLLMMessage()
- TreeManager.AddFantasyMessages() → AddLLMMessages()
- Message.ToFantasyMessages() → ToLLMMessages()
- FromFantasyMessage() → FromLLMMessage()
- npmToFantasyProvider → npmToLLMProvider
- isProviderFantasySupported() → isProviderLLMSupported()

All internal callers migrated to new names. ~30 comments updated
to remove Fantasy references across pkg/kit/, internal/agent/,
internal/models/, internal/message/, internal/session/.

Documentation updates:
- AGENTS.md: added Public SDK rules section (no dependency leakage,
  naming conventions, deprecation pattern)
- README.md: removed Fantasy references
- pkg/kit/README.md: full rewrite with current API surface
- skills/kit-sdk/SKILL.md: updated examples and type references
- www/pages/providers.md, www/pages/cli/commands.md: updated

Ed Zynda f36166bee5 rename spawn_subagent tool to subagent; remove redundant toolDisplayNames map
Tool rename (breaking change for ToolName string comparisons in event handlers):
- internal/core/subagent.go: Name field 'spawn_subagent' → 'subagent'
- internal/extensions/wrapper.go: update coreToolKinds map key
- pkg/kit/events.go: update coreToolKinds map key and ToolKindSubagent comment
- pkg/kit/extensions_bridge.go: update three ToolName == ... guards
- internal/ui/tool_renderers.go: update two toolName == ... case guards
- internal/ui/stream.go: remove special-case branch (toolName is now already
  'subagent', so the title-case fallback produces 'Subagent' naturally)

Comments/docs updated everywhere (no logic changes):
- internal/core/tools.go, internal/extensions/api.go, events.go
- pkg/kit/kit.go, tools.go
- examples/extensions/subagent-test.go, kit-telegram/main.go
- README.md, skills/kit-sdk/SKILL.md
- www/pages/advanced/subagents.md, extensions/capabilities.md
- www/pages/index.md, sdk/callbacks.md
- www/public/session/index.html (tracked UI asset)

Redundant toolDisplayNames map removed (item #14):
- internal/ui/messages.go: delete the 7-entry map whose every value was
  identical to what the title-case fallback already produced; simplify
  toolDisplayName() to just the fallback
2026-03-29 00:24:18 +03:00
Ed Zynda 879e81f9b5 remove deprecated API methods: GetExtRunner, GetBufferedLogger, GetAgent, PromptWithCallbacks
These methods have been deprecated since the narrow-accessor and event-
subscriber APIs were introduced. No callers exist in this repository.

- pkg/kit/kit.go: remove GetExtRunner(), GetBufferedLogger(), GetAgent(),
  and PromptWithCallbacks(); update Subscribe() doc comment which still
  mentioned PromptWithCallbacks; tighten section header comment
- pkg/kit/README.md: replace PromptWithCallbacks example with the
  OnToolCall/OnToolResult/OnStreaming subscriber pattern; remove method
  from the quick-reference list
- README.md: same example migration in the SDK section
- www/pages/sdk/callbacks.md: remove the PromptWithCallbacks section
  entirely; the event-based monitoring section that followed it is now
  the lead content
- www/pages/sdk/overview.md: remove PromptWithCallbacks row from the
  prompt-variant table
- skills/kit-sdk/SKILL.md: remove the deprecated legacy callback snippet

Ed Zynda 4ae03aab7c refactor: move extension testing package to pkg/
Move the extension testing package from internal/extensions/test to
pkg/extensions/test to make it publicly importable by external extension
authors.

Changes:
- Moved test package files to pkg/extensions/test/
- Updated all imports from internal/ to pkg/ path:
  - README.md
  - examples/extensions/tool-logger_test.go
  - examples/extensions/extension_test_template.go

Ed Zynda e613a07773 feat: add ACP server mode (kit acp)
Implement Agent Client Protocol server allowing ACP-compatible clients
(e.g. OpenCode) to drive Kit as a remote coding agent over stdio.

- internal/acpserver/agent.go: acp.Agent implementation bridging Kit's
  LLM execution, tool system, and event bus to ACP session updates
- internal/acpserver/session.go: session registry mapping ACP sessions
  to persisted Kit JSONL tree sessions
- cmd/acp.go: cobra subcommand wiring stdio JSON-RPC connection

Ed Zynda 57250a3a3d refactor: remove --prompt flag, positional args are the only way
Drop the --prompt/-p flag entirely. Non-interactive mode is now
triggered by passing positional arguments:

  kit "Explain this"
  kit @file.go "Review this" --json
  kit @a.go @b.go --quiet

Updated extension examples (kit-kit.go, subagent-widget.go) to pass
the prompt as a positional arg. Updated AGENTS.md and README.md.

Ed Zynda 626f1105c9 move SDK to pkg/kit, extract shared logic from cmd, relocate main to cmd/kit
Restructure the codebase so the CLI app consumes the SDK rather than
the SDK wrapping CLI internals. This eliminates the circular dependency
(sdk -> cmd -> sdk) and establishes pkg/kit as the canonical API.

Key changes:
- Create pkg/kit/ with InitConfig, SetupAgent, BuildProviderConfig
  extracted from cmd/root.go and cmd/setup.go as parameterized functions
- Move sdk/kit.go -> pkg/kit/kit.go (remove cmd import, use local calls)
- Move sdk/types.go -> pkg/kit/types.go
- Move main.go -> cmd/kit/main.go (standard Go project layout)
- cmd/root.go and cmd/setup.go now delegate to pkg/kit, injecting
  CLI-specific state (quietFlag) via the Quiet field on AgentSetupOptions
- Add setSDKDefaults() for cobra-free SDK usage (viper defaults)
- Fix .gitignore: kit -> /kit (was blocking cmd/kit/ and pkg/kit/)
- Update .goreleaser.yaml, Taskfile.yml, AGENTS.md, contribute/build.sh,
  README.md for new cmd/kit entrypoint and pkg/kit import paths
- Add plans/ with 10 detailed SDK revamp plans and Taskfile.yml
- Delete sdk/ directory entirely
