release: v3.5.5

OpenCode 1.2.0+ changed reasoning-delta and text-delta to emit
'message.part.delta' instead of 'message.part.updated'. Without
handling this event, lastUpdate was only refreshed at reasoning-start
and reasoning-end, leaving a gap where extended thinking (>3min)
could trigger stale timeout.

Accept both event types as heartbeat sources for forward compatibility.

-## STEP 5: VERIFY GITHUB RELEASE
+## STEP 5: VERIFY RELEASE & PREVIEW AUTO-GENERATED CONTENT
+
+Two goals: confirm the release exists, then show the user what the workflow already generated.
 
-Get the new version and verify release exists:
 ```bash
-# Get new version from package.json (workflow updates it)
+# Pull latest (workflow committed version bump)
 git pull --rebase
 NEW_VERSION=$(node -p "require('./package.json').version")

-## STEP 6: DRAFT ENHANCED RELEASE NOTES
-
-Analyze commits since the previous version and draft release notes following project conventions:
-
-### For PATCH releases:
-Keep simple format - just list commits:
-```markdown
-- {hash} {conventional commit message}
-- ...
-```
-
-### For MINOR releases:
-Use feature-focused format:
-```markdown
-## New Features
-
-### Feature Name
-- Description of what it does
-- Why it matters
-
-## Bug Fixes
-- fix(scope): description
-
-## Improvements
-- refactor(scope): description
-```
-
-### For MAJOR releases:
-Full changelog format:
-```markdown
-# v{version}
-
-Brief description of the release.
-
-## What's New Since v{previous}
-
-### Breaking Changes
-- Description of breaking change
-
-### Features
-- **Feature Name**: Description
-
-### Bug Fixes
-- Description
-
-### Documentation
-- Description
-
-## Migration Guide (if applicable)
-...
-```
-
-**CRITICAL: The enhanced notes must ADD to existing workflow-generated notes, not replace them.**
-
----
-
-## STEP 7: UPDATE GITHUB RELEASE
-
-**ZERO CONTENT LOSS POLICY:**
-- First, fetch the existing release body with `gh release view`
-- Your enhanced notes must be PREPENDED to the existing content
-- **NOT A SINGLE CHARACTER of existing content may be removed or modified**
-- The final release body = `{your_enhanced_notes}\n\n---\n\n{existing_body_exactly_as_is}`
+**After verifying, generate a local preview of the auto-generated content:**
 
 ```bash
-# Get existing body
-EXISTING_BODY=$(gh release view "v${NEW_VERSION}" --json body --jq '.body')
+bun run script/generate-changelog.ts
+```
 
-# Write enhanced notes to temp file (prepend to existing)
-cat > /tmp/release-notes-v${NEW_VERSION}.md << 'EOF'
-{your_enhanced_notes}
+<agent-instruction>
+After running the preview, present the output to the user and say:
+
+> **The following content is ALREADY included in the release automatically:**
+> - Commit changelog (grouped by feat/fix/refactor)
+> - Contributor thank-you messages (for non-team contributors)
+>
+> You do NOT need to write any of this. It's handled.
+>
+> **For a patch release**, this is usually sufficient on its own. However, if there are notable bug fixes or changes worth highlighting, an enhanced summary can be added.
+> **For a minor/major release**, an enhanced summary is **required** — I'll draft one in the next step.
+
+Wait for the user to acknowledge before proceeding.
+</agent-instruction>
 
 ---
 
-EOF
+## STEP 6: DRAFT ENHANCED RELEASE SUMMARY
 
-# Append existing body EXACTLY as-is (zero modifications)
-echo "$EXISTING_BODY" >> /tmp/release-notes-v${NEW_VERSION}.md
+<decision-gate>
 
-# Update release
-gh release edit "v${NEW_VERSION}" --notes-file /tmp/release-notes-v${NEW_VERSION}.md
+| Release Type | Action |
+|-------------|--------|
+| **patch** | ASK the user: "Would you like me to draft an enhanced summary highlighting the key bug fixes / changes? Or is the auto-generated changelog sufficient?" If user declines → skip to Step 8. If user accepts → draft a concise bug-fix / change summary below. |
+| **minor** | MANDATORY. Draft a concise feature summary. Do NOT proceed without one. |
+| **major** | MANDATORY. Draft a full release narrative with migration notes if applicable. Do NOT proceed without one. |
+
+</decision-gate>
+
+### What You're Writing (and What You're NOT)
+
+You are writing the **headline layer** — a product announcement that sits ABOVE the auto-generated commit log. Think "release blog post", not "git log".
+
+<rules>
+- NEVER duplicate commit messages. The auto-generated section already lists every commit.
+- NEVER write generic filler like "Various bug fixes and improvements" or "Several enhancements".
+- ALWAYS focus on USER IMPACT: what can users DO now that they couldn't before?
+- ALWAYS group by THEME or CAPABILITY, not by commit type (feat/fix/refactor).
+- ALWAYS use concrete language: "You can now do X" not "Added X feature".
+</rules>
+
+<examples>
+<bad title="Commit regurgitation — DO NOT do this">
+## What's New
+- feat(auth): add JWT refresh token rotation
+- fix(auth): handle expired token edge case
+- refactor(auth): extract middleware
+</bad>
+
+<good title="User-impact narrative — DO this">
+## 🔐 Smarter Authentication
+
+Token refresh is now automatic and seamless. Sessions no longer expire mid-task — the system silently rotates credentials in the background. If you've been frustrated by random logouts, this release fixes that.
+</good>
+
+<bad title="Vague filler — DO NOT do this">
+## Improvements
+- Various performance improvements
+- Bug fixes and stability enhancements
+</bad>
+
+<good title="Specific and measurable — DO this">
+## ⚡ 3x Faster Rule Parsing
+
+Rules are now cached by file modification time. If your project has 50+ rule files, you'll notice startup is noticeably faster — we measured a 3x improvement in our test suite.
+</good>
+</examples>
+
+### Drafting Process
+
+1. **Analyze** the commit list from Step 5's preview. Identify 2-5 themes that matter to users.

+
+## PLUGIN INITIALIZATION (10 steps)
+
+1. `injectServerAuthIntoClient(ctx.client)` — Auth injection
+2. `startTmuxCheck()` — Tmux availability
+3. `loadPluginConfig(ctx.directory, ctx)` — User + project config merge → Zod validation
+4. `createFirstMessageVariantGate()` — First message variant override gate
+5. `createModelCacheState()` — Model context limits cache
+6. `createManagers(...)` → 4 managers:
+   - `TmuxSessionManager` — Multi-pane tmux sessions
+   - `BackgroundManager` — Parallel subagent execution
+   - `SkillMcpManager` — MCP server lifecycle
+   - `ConfigHandler` — Plugin config API to OpenCode
+7. `createTools(...)` → `createSkillContext()` + `createAvailableCategories()` + `createToolRegistry()`
+8. `createHooks(...)` → `createCoreHooks()` + `createContinuationHooks()` + `createSkillHooks()`
+9. `createPluginInterface(...)` → 7 OpenCode hook handlers
+10. Return plugin with `experimental.session.compacting`
+
+## HOOK REGISTRATION (3 tiers)
+
+**Core Hooks** (`create-core-hooks.ts`):
+- Session (20): context-window-monitor, session-recovery, think-mode, ralph-loop, anthropic-effort, ...
+- Tool Guard (8): comment-checker, tool-output-truncator, rules-injector, write-existing-file-guard, ...
+- Transform (4): claude-code-hooks, keyword-detector, context-injector, thinking-block-validator
+
+**Continuation Hooks** (`create-continuation-hooks.ts`):
+- 7 hooks: stop-continuation-guard, compaction-context-injector, todo-continuation-enforcer, atlas, ...
+
+**Skill Hooks** (`create-skill-hooks.ts`):
+- 2 hooks: category-skill-reminder, auto-slash-command
+
+## PLUGIN INTERFACE (7 OpenCode handlers)
+
+| Handler | Source | Purpose |
+|---------|--------|---------|
+| `tool` | filteredTools | All registered tools |
+| `chat.params` | createChatParamsHandler | Anthropic effort level |
+| `chat.message` | createChatMessageHandler | First message variant, session setup |
+| `experimental.chat.messages.transform` | createMessagesTransformHandler | Context injection, keyword detection |
+| `config` | configHandler | Agent/MCP/command registration |
+| `event` | createEventHandler | Session lifecycle |
+| `tool.execute.before` | createToolExecuteBeforeHandler | Pre-tool hooks |
+| `tool.execute.after` | createToolExecuteAfterHandler | Post-tool hooks |
+
+## SAFE HOOK CREATION PATTERN
+
+```typescript
+const hook = isHookEnabled("hook-name")
+  ? safeCreateHook("hook-name", () => createHookFactory(ctx), { enabled: safeHookEnabled })
+  : null;
+```
+
+All hooks use this pattern for graceful degradation on failure.

 ## OVERVIEW
 
-11 AI agents for multi-model orchestration. Each agent has factory function + metadata + fallback chains.
-
-**Primary Agents** (respect UI model selection):
-- Sisyphus, Atlas, Prometheus
-
-**Subagents** (use own fallback chains):
-- Hephaestus, Oracle, Librarian, Explore, Multimodal-Looker, Metis, Momus, Sisyphus-Junior
+11 AI agents with factory functions, fallback chains, and model-specific prompt variants. Each agent has metadata (category, cost, triggers) and configurable tool restrictions.

+## HOW TO ADD
+
+1. Create `src/agents/my-agent.ts` exporting factory + metadata
+2. Add to `agentSources` in `src/agents/builtin-agents/`
+3. Update `AgentNameSchema` in `src/config/schema/agent-names.ts`
+4. Register in `src/plugin-handlers/agent-config-handler.ts`
+
+## KEY PATTERNS
+
+- **Factory**: `createXXXAgent(model): AgentConfig`
 - **Metadata**: `XXX_PROMPT_METADATA` with category, cost, triggers
-- **Tool restrictions**: `createAgentToolRestrictions(tools)` or `createAgentToolAllowlist(tools)`
-- **Thinking**: 32k budget tokens for Sisyphus, Oracle, Prometheus, Atlas
-- **Model-specific routing**: Atlas, Sisyphus-Junior have GPT vs Claude prompt variants
+- **Model-specific prompts**: Atlas, Sisyphus-Junior have GPT vs Claude variants
+- **Dynamic prompts**: Sisyphus, Hephaestus use `dynamic-agent-prompt-builder.ts` to inject available tools/skills/categories
 
 ## ANTI-PATTERNS
-- **Trust reports**: NEVER trust "I'm done" - verify outputs
-- **High temp**: Don't use >0.3 for code agents
+
+- **Trust agent self-reports**: NEVER — always verify outputs
+- **High temperature**: Don't use >0.3 for code agents
 - **Sequential calls**: Use `task` with `run_in_background` for exploration
-- **Prometheus writing code**: Planner only - never implements
+- **Prometheus writing code**: Planner only — never implements

 ## HOW TO ADD CHECK
 
 1. Create `src/cli/doctor/checks/my-check.ts`
-2. Export `getXXXCheckDefinition()` factory returning `CheckDefinition`
+2. Export `getXXXCheckDefinition()` returning `CheckDefinition`
 3. Add to `getAllCheckDefinitions()` in `checks/index.ts`
 
-## TUI FRAMEWORK
-

 ## ANTI-PATTERNS
 
-- **Blocking in non-TTY**: Always check `process.stdout.isTTY`
-- **Direct JSON.parse**: Use `parseJsonc()` from shared utils
-- **Silent failures**: Return `warn` or `fail` in doctor instead of throwing
-- **Hardcoded paths**: Use `getOpenCodeConfigPaths()` from `config-manager.ts`

- * - `antigravity-gemini-3-pro` with variants: low, high
- * - `antigravity-gemini-3-flash` with variants: minimal, low, medium, high
- *
- * Legacy tier-suffixed names (e.g., `antigravity-gemini-3-pro-high`) still work
