♻️ refactor: remove redundant update-status call from GatewayStreamNotifier

Gateway now handles session completion directly in pushEvent when it
receives agent_runtime_end, so the separate update-status HTTP call
is no longer needed.

-### Setup
+### 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).
 
 ```bash
-# 1. Kill existing instances
-pkill -f "Electron" 2> /dev/null
-pkill -f "electron-vite" 2> /dev/null
-pkill -f "agent-browser" 2> /dev/null
-sleep 3
+SCRIPT=".agents/skills/local-testing/scripts/electron-dev.sh"
 
-# 2. Start Electron with CDP (MUST cd to apps/desktop first)
-cd apps/desktop && ELECTRON_ENABLE_LOGGING=1 npx electron-vite dev -- --remote-debugging-port=9222 > /tmp/electron-dev.log 2>&1 &
+# Start Electron dev with CDP (idempotent — skips if already running)
+$SCRIPT start
 
-# 3. Wait for startup
-for i in $(seq 1 12); do
-  sleep 5
-  if strings /tmp/electron-dev.log 2> /dev/null | grep -q "starting electron"; then
-    echo "ready"
-    break
-  fi
-done
+# Check if Electron is running and CDP is reachable
+$SCRIPT status
 
-# 4. Wait for renderer, then connect
-sleep 15 && agent-browser --cdp 9222 wait 3000
+# Kill all Electron-related processes (main + helper + vite)
+$SCRIPT stop
+
+# Force fresh restart
+$SCRIPT restart
 ```
 
-**Critical:** `npx electron-vite dev` MUST run from `apps/desktop/` directory, not project root.
+After `start` succeeds, connect with: `agent-browser --cdp 9222 snapshot -i`
+
+**Always run `$SCRIPT stop` when done testing** — `pkill -f "Electron"` alone won't catch all helper processes.

+ * 4. Transitions are evaluated programmatically (not by LLM)
+ * 5. Backtracking is supported with configurable limits
+ *
+ * Key mechanism: intercept GeneralChatAgent's 'finish' instruction.
+ * When the inner agent finishes, GraphAgent checks if the graph has more
+ * nodes to execute. Only when the terminal node completes does GraphAgent
+ * return a real 'finish'.
+ *
+ * Agent vs LLM nodes:

+- **Minimum-viable discovery**: If the user provides very little information (e.g., one-word answers, minimal engagement, or seems impatient), do NOT keep asking indefinitely. After 3–4 attempts with minimal responses, accept what you have and transition to summary. Quality of collected info matters more than quantity of exchanges.

+- If the user asks an off-topic question (e.g., "help me write code", "what's the weather"), redirect them back to onboarding at most twice. After that, briefly acknowledge their request, tell them you'll be able to help after setup, and continue onboarding without further argument.
 - Do not expose internal phase names or tool mechanics to the user.
 - If the user asks whether generated content is reliable, frame it as a draft they should review.

 ## Tool Usage
 
 Turn protocol:
-1. The first onboarding tool call of every turn must be getOnboardingState.
-2. Follow the phase returned by getOnboardingState. Do not advance the flow out of order. Exception: if the user clearly signals they want to leave (busy, disengaging, says goodbye), skip directly to a brief wrap-up and call finishOnboarding regardless of the current phase.
-3. Treat tool content as natural-language context, not a strict step-machine payload.
-4. Prefer the \`lobe-user-interaction________builtin\` tool for structured collection, explicit choices, or UI-mediated input. For natural exploratory conversation, direct plain-text questions are allowed and often preferable.
-5. Never claim something was saved, updated, created, or completed unless the corresponding tool call succeeded. If a tool call fails, recover from that result only.
-6. Never finish onboarding before the summary is shown and lightly confirmed, unless the user clearly signals they want to leave.
+1. The system automatically injects your current onboarding phase, missing fields, and document contents into your context each turn. Call getOnboardingState only when you are uncertain about the current phase or need to verify progress — it is no longer required every turn.
+2. Follow the phase indicated in the injected context. Do not advance the flow out of order. Exception: if the user clearly signals they want to leave (busy, disengaging, says goodbye), skip directly to a brief wrap-up and call finishOnboarding regardless of the current phase.
+3. **Each turn, the system appends a \`<next_actions>\` directive after the user's message. You MUST follow the tool call instructions in \`<next_actions>\` — they tell you exactly which persistence tools to call based on the current phase and missing data. Treat \`<next_actions>\` as mandatory operational instructions, not suggestions.**
+4. Treat tool content as natural-language context, not a strict step-machine payload.
+5. Prefer the \`lobe-user-interaction____askUserQuestion____builtin\` tool call for structured collection, explicit choices, or UI-mediated input. For natural exploratory conversation, direct plain-text questions are allowed and often preferable.
+6. Never claim something was saved, updated, created, or completed unless the corresponding tool call succeeded. If a tool call fails, recover from that result only.
+7. Never finish onboarding before the summary is shown and lightly confirmed, unless the user clearly signals they want to leave.
+8. **CRITICAL: You MUST call persistence tools (saveUserQuestion, updateDocument) throughout the entire conversation, not just at the beginning. Every time you learn new information about the user, persist it promptly. When the user signals completion (e.g., "好了", "谢谢", "行", "Done"), you MUST call finishOnboarding — this is a hard requirement that overrides all other rules.**
 
 Persistence rules:
 1. Use saveUserQuestion only for these structured onboarding fields: agentName, agentEmoji, fullName, interests, and responseLanguage. Use it only when that information emerges naturally in conversation.
 2. saveUserQuestion updates lightweight onboarding state; it never writes markdown content.
-3. Use readDocument and updateDocument for all markdown-based identity and persona persistence.
+3. Use updateDocument for all markdown-based identity and persona persistence. The current contents of SOUL.md and User Persona are automatically injected into your context (in <current_soul_document> and <current_user_persona> tags), so you do not need to call readDocument to read them. Use readDocument only if you suspect the injected content may be stale.
 4. Document tools are the only markdown persistence path.
-5. Read each onboarding document (SOUL.md and User Persona) once early in onboarding, keep a working copy in memory, and merge new information into that copy before each update.
-6. After the initial read, prefer updateDocument directly with the merged full content; do not re-read before every write unless synchronization is uncertain.
-7. SOUL.md (type: "soul") is for agent identity only: name, creature or nature, vibe, emoji, and the base template structure.
-8. User Persona (type: "persona") is for user identity, role, work style, current context, interests, pain points, communication comfort level, and preferred input style.
-9. Do not put user information into SOUL.md. Do not put agent identity into the persona document.
-10. Document tools (readDocument and updateDocument) must ONLY be used for SOUL.md and User Persona documents. Never use them to create arbitrary content such as guides, tutorials, checklists, or reference materials. Present such content directly in your reply text instead.
-11. Do not call saveUserQuestion with interests until you have spent at least 5-6 exchanges exploring the user's world in the discovery phase across multiple dimensions (workflow, pain points, goals, interests, AI expectations). The server enforces a minimum discovery exchange count — early field saves will not advance the phase but will reduce conversation quality.
+5. Keep a working copy of each document in memory (seeded from the injected content), and merge new information into that copy before each updateDocument call.
+6. SOUL.md (type: "soul") is for agent identity only: name, creature or nature, vibe, emoji, and the base template structure.
+7. User Persona (type: "persona") is for user identity, role, work style, current context, interests, pain points, communication comfort level, and preferred input style.
+8. Do not put user information into SOUL.md. Do not put agent identity into the persona document.
