 ## CONVENTIONS
 
-- **Package manager**: Bun only (`bun run`, `bun build`, `bunx`)
+- **Bun only**: `bun run`, `bun test`, `bunx` (NEVER npm/npx)
 - **Types**: bun-types (not @types/node)
-- **Build**: Dual output - `bun build` (ESM) + `tsc --emitDeclarationOnly`
-- **Exports**: Barrel pattern - `export * from "./module"` in index.ts
-- **Directory naming**: kebab-case (`ast-grep/`, `claude-code-hooks/`)
-- **Tool structure**: index.ts, types.ts, constants.ts, tools.ts, utils.ts
-- **Hook pattern**: `createXXXHook(input: PluginInput)` returning event handlers
-- **Test style**: BDD comments `#given`, `#when`, `#then` (same as AAA)
+- **Build**: `bun build` (ESM) + `tsc --emitDeclarationOnly`
+- **Exports**: Barrel pattern in index.ts; explicit named exports for tools/hooks
+- **Naming**: kebab-case directories, createXXXHook/createXXXTool factories
+- **Testing**: BDD comments `#given`, `#when`, `#then` (same as AAA)
+- **Temperature**: 0.1 for code agents, max 0.3
 
-## ANTI-PATTERNS (THIS PROJECT)
+## ANTI-PATTERNS
 
-- **npm/yarn**: Use bun exclusively
-- **@types/node**: Use bun-types
-- **Bash file ops**: Never mkdir/touch/rm/cp/mv for file creation in code
-- **Direct bun publish**: GitHub Actions workflow_dispatch only (OIDC provenance)
-- **Local version bump**: Version managed by CI workflow
-- **Year 2024**: NEVER use 2024 in code/prompts (use current year)
-- **Rush completion**: Never mark tasks complete without verification
-- **Over-exploration**: Stop searching when sufficient context found
-
-## UNIQUE STYLES
-
-- **Platform**: Union type `"darwin" | "linux" | "win32" | "unsupported"`
-- **Optional props**: Extensive `?` for optional interface properties
-- **Flexible objects**: `Record<string, unknown>` for dynamic configs
-- **Error handling**: Consistent try/catch with async/await
-- **Agent tools**: `tools: { include: [...] }` or `tools: { exclude: [...] }`
-- **Temperature**: Most agents use `0.1` for consistency
-- **Hook naming**: `createXXXHook` function convention
+| Category | Forbidden |
+|----------|-----------|
+| Type Safety | `as any`, `@ts-ignore`, `@ts-expect-error` |
+| Package Manager | npm, yarn, npx |
+| File Ops | Bash mkdir/touch/rm for code file creation |
+| Publishing | Direct `bun publish`, local version bump |
+| Agent Behavior | High temp (>0.3), broad tool access, sequential agent calls |
+| Hooks | Heavy PreToolUse logic, blocking without reason |
+| Year | 2024 in code/prompts (use current year) |

-| `aggressive_truncation`     | `false` | 超出 token 限制时，激进地截断工具输出以适应限制。比默认截断更激进。不够的话会回退到摘要/恢复。                                                     |
-| `auto_resume`               | `false` | 从 thinking block 错误或 thinking disabled violation 成功恢复后，自动恢复会话。提取最后一条用户消息继续执行。                                     |
-| `truncate_all_tool_outputs` | `true`  | 为防止提示过长，根据上下文窗口使用情况动态截断所有工具输出。如需完整工具输出，设置为 `false` 禁用此功能。                                           |
-| `dcp_on_compaction_failure` | `false` | 启用后，DCP（动态上下文剪枝）仅在压缩（摘要）失败后运行，然后重试压缩。平时 DCP 不会运行。当达到 token 限制时需要更智能的恢复请启用此选项。                   |

+| `preemptive_compaction_threshold` | `0.85`  | 触发预防性压缩的阈值比例（0.5-0.95）。`preemptive-compaction` 钩子默认启用；此选项用于自定义阈值。                                                     |
+| `truncate_all_tool_outputs`       | `false` | 截断所有工具输出，而不仅仅是白名单工具（Grep、Glob、LSP、AST-grep）。Tool output truncator 默认启用 - 使用 `disabled_hooks` 禁用。                    |
+| `aggressive_truncation`           | `false` | 超出 token 限制时，激进地截断工具输出以适应限制。比默认截断更激进。不够的话会回退到摘要/恢复。                                                     |

+## AGENT MODELS
+
+| Agent | Model | Fallback | Purpose |
+|-------|-------|----------|---------|
+| Sisyphus | anthropic/claude-opus-4-5 | - | Orchestrator with extended thinking |
+| oracle | openai/gpt-5.2 | - | Architecture, debugging, review |
+| librarian | anthropic/claude-sonnet-4-5 | google/gemini-3-flash | Docs, GitHub research |
+| explore | opencode/grok-code | gemini-3-flash, haiku-4-5 | Contextual grep |
+| frontend-ui-ux-engineer | google/gemini-3-pro-preview | - | Beautiful UI code |
+| document-writer | google/gemini-3-pro-preview | - | Technical writing |
+| multimodal-looker | google/gemini-3-flash | - | Visual analysis |
+
+## HOW TO ADD
+
+1. Create `src/agents/my-agent.ts`:
+   ```typescript
+   export const myAgent: AgentConfig = {
+     model: "provider/model-name",
+     temperature: 0.1,
+     system: "...",
+     tools: { include: ["tool1"] },
+   }
+   ```
+2. Add to `builtinAgents` in index.ts
+3. Update types.ts if new config options
+
+## MODEL FALLBACK
+
+`createBuiltinAgents()` handles fallback:
+1. User config override
+2. Installer settings (claude max20, gemini antigravity)
+3. Default model
+
+## ANTI-PATTERNS
+
+- High temperature (>0.3) for code agents
+- Broad tool access (prefer explicit `include`)
+- Monolithic prompts (delegate to specialists)
+- Missing fallbacks for rate-limited models

+
+## KEY COMPONENTS
+
+| File | Purpose |
+|------|---------|
+| fetch.ts | URL rewriting, token injection, retries |
+| thinking.ts | Extract `<antThinking>` blocks |
+| response.ts | Streaming SSE parsing |
+| oauth.ts | Browser-based OAuth flow |
+| token.ts | Token persistence, expiry |
+
+## HOW IT WORKS
+
+1. **Intercept**: fetch.ts intercepts Anthropic/Google requests
+2. **Rewrite**: URLs → Antigravity proxy endpoints
+3. **Auth**: Bearer token from stored OAuth credentials
+4. **Response**: Streaming parsed, thinking blocks extracted
+5. **Transform**: Normalized for OpenCode
+
+## FEATURES
+
+- Multi-account (up to 10 Google accounts)
+- Auto-fallback on rate limit
+- Thinking blocks preserved
+- Antigravity proxy for AI Studio access
+
+## ANTI-PATTERNS
+
+- Direct API calls (use fetch interceptor)
+- Tokens in code (use token.ts storage)
+- Ignoring refresh (check expiry first)
+- Blocking on OAuth (always async)

+
+## CLI COMMANDS
+
+| Command | Purpose |
+|---------|---------|
+| `install` | Interactive setup wizard |
+| `doctor` | Environment health checks |
+| `run` | Launch OpenCode session |
+
+## DOCTOR CHECKS
+
+17+ checks in `doctor/checks/`:
+- version.ts (OpenCode >= 1.0.150)
+- config.ts (plugin registered)
+- bun.ts, node.ts, git.ts
+- anthropic-auth.ts, openai-auth.ts, google-auth.ts
+- lsp-*.ts, mcp-*.ts
+
+## CONFIG-MANAGER (669 lines)
+
+- JSONC support (comments, trailing commas)
+- Multi-source: User (~/.config/opencode/) + Project (.opencode/)
+- Zod validation
+- Legacy format migration
+- Error aggregation for doctor
+
+## HOW TO ADD CHECK
+
+1. Create `src/cli/doctor/checks/my-check.ts`:
+   ```typescript
+   export const myCheck: DoctorCheck = {
+     name: "my-check",
+     category: "environment",
+     check: async () => {
+       return { status: "pass" | "warn" | "fail", message: "..." }
+     }
+   }
+   ```
+2. Add to `src/cli/doctor/checks/index.ts`
+
+## ANTI-PATTERNS
+
+- Blocking prompts in non-TTY (check `process.stdout.isTTY`)
+- Hardcoded paths (use shared utilities)
+- JSON.parse for user files (use parseJsonc)
+- Silent failures in doctor checks

 ## LOADER PRIORITY
 
-Each loader reads from multiple directories (highest priority first):
-
-| Loader | Priority Order |
-|--------|---------------|
+| Loader | Priority (highest first) |
+|--------|--------------------------|
 | Commands | `.opencode/command/` > `~/.config/opencode/command/` > `.claude/commands/` > `~/.claude/commands/` |
-| Skills | `.claude/skills/` > `~/.claude/skills/` |
+| Skills | `.opencode/skill/` > `~/.config/opencode/skill/` > `.claude/skills/` > `~/.claude/skills/` |
 | Agents | `.claude/agents/` > `~/.claude/agents/` |
 | MCPs | `.claude/.mcp.json` > `.mcp.json` > `~/.claude/.mcp.json` |
 
-## HOW TO ADD A LOADER
-
-1. Create directory: `src/features/claude-code-my-loader/`
-2. Create files:
-   - `loader.ts`: Main loader logic with `load()` function
-   - `types.ts`: TypeScript interfaces
-   - `index.ts`: Barrel export
-3. Pattern: Read from multiple dirs, merge with priority, return normalized config
-
-## BACKGROUND AGENT SPECIFICS
-
-- **Task lifecycle**: pending → running → completed/failed
-- **Notifications**: OS notification on task complete (configurable)
-- **Result retrieval**: `background_output` tool with task_id
-- **Cancellation**: `background_cancel` with task_id or all=true
-
 ## CONFIG TOGGLES
 
-Disable features in `oh-my-opencode.json`:
-
 ```json
 {
   "claude_code": {
-    "mcp": false,      // Skip .mcp.json loading
-    "commands": false, // Skip commands/*.md loading
-    "skills": false,   // Skip skills/*/SKILL.md loading
-    "agents": false,   // Skip agents/*.md loading
+    "mcp": false,      // Skip .mcp.json
+    "commands": false, // Skip commands/*.md
+    "skills": false,   // Skip skills/*/SKILL.md
+    "agents": false,   // Skip agents/*.md
     "hooks": false     // Skip settings.json hooks
   }
 }
 ```
 
-## HOOK MESSAGE INJECTOR
+## BACKGROUND AGENT
 
-- **Purpose**: Inject system messages into conversation at specific points
-- **Timing**: PreToolUse, PostToolUse, UserPromptSubmit, Stop
-- **Format**: Returns `{ messages: [{ role: "user", content: "..." }] }`
+- Lifecycle: pending → running → completed/failed
+- OS notification on complete
+- `background_output` to retrieve results
+- `background_cancel` with task_id or all=true
 
-## ANTI-PATTERNS (FEATURES)
+## SKILL MCP
 
-- **Blocking on load**: Loaders run at startup, keep them fast
-- **No error handling**: Always try/catch, log failures, return empty on error
-- **Ignoring priority**: Higher priority dirs must override lower
-- **Modifying user files**: Loaders read-only, never write to ~/.claude/
+- MCP servers embedded in skill YAML frontmatter
+- Lazy client loading, session-scoped cleanup
+- `skill_mcp` tool exposes capabilities
+
+## ANTI-PATTERNS
+
+- Blocking on load (loaders run at startup)
+- No error handling (always try/catch)
+- Ignoring priority order
+- Writing to ~/.claude/ (read-only)

+**While background agents run**, main session does:
+
+#### 1. Bash Structural Analysis
+\`\`\`bash
+# Directory depth + file counts
+find . -type d -not -path '*/\\.*' -not -path '*/node_modules/*' -not -path '*/venv/*' -not -path '*/dist/*' -not -path '*/build/*' | awk -F/ '{print NF-1}' | sort -n | uniq -c
+
+# Files per directory (top 30)
+find . -type f -not -path '*/\\.*' -not -path '*/node_modules/*' | sed 's|/[^/]*$||' | sort | uniq -c | sort -rn | head -30
+
+# Code concentration by extension
+find . -type f \\( -name "*.py" -o -name "*.ts" -o -name "*.tsx" -o -name "*.js" -o -name "*.go" -o -name "*.rs" \\) -not -path '*/node_modules/*' | sed 's|/[^/]*$||' | sort | uniq -c | sort -rn | head -20
+
+# Existing AGENTS.md / CLAUDE.md
+find . -type f \\( -name "AGENTS.md" -o -name "CLAUDE.md" \\) -not -path '*/node_modules/*' 2>/dev/null
+\`\`\`
+
+#### 2. Read Existing AGENTS.md
+\`\`\`
+For each existing file found:
+  Read(filePath=file)
+  Extract: key insights, conventions, anti-patterns
+  Store in EXISTING_AGENTS map
+\`\`\`
+
+If \`--create-new\`: Read all existing first (preserve context) → then delete all → regenerate.
+
+#### 3. LSP Codemap (if available)
+\`\`\`
+lsp_servers()  # Check availability
+
+# Entry points (parallel)
+lsp_document_symbols(filePath="src/index.ts")
+lsp_document_symbols(filePath="main.py")
+
+# Key symbols (parallel)
+lsp_workspace_symbols(filePath=".", query="class")
+lsp_workspace_symbols(filePath=".", query="interface")
+lsp_workspace_symbols(filePath=".", query="function")
+
+# Centrality for top exports
+lsp_find_references(filePath="...", line=X, character=Y)
+\`\`\`
+
+**LSP Fallback**: If unavailable, rely on explore agents + AST-grep.
+
+### Collect Background Results
+
+\`\`\`
+// After main session analysis done, collect all task results
+for each task_id: background_output(task_id="...")
+\`\`\`
+
+**Merge: bash + LSP + existing + explore findings. Mark "discovery" as completed.**
+
+---
+
+## Phase 2: Scoring & Location Decision
+
+**Mark "scoring" as in_progress.**
+
+### Scoring Matrix
+
+| Factor | Weight | High Threshold | Source |
+|--------|--------|----------------|--------|
+| File count | 3x | >20 | bash |
+| Subdir count | 2x | >5 | bash |
+| Code ratio | 2x | >70% | bash |
+| Unique patterns | 1x | Has own config | explore |
+| Module boundary | 2x | Has index.ts/__init__.py | bash |
+| Symbol density | 2x | >30 symbols | LSP |
+| Export count | 2x | >10 exports | LSP |
+| Reference centrality | 3x | >20 refs | LSP |
+
+### Decision Rules
+
+| Score | Action |
+|-------|--------|
+| **Root (.)** | ALWAYS create |
+| **>15** | Create AGENTS.md |
+| **8-15** | Create if distinct domain |
+| **<8** | Skip (parent covers) |
+
+### Output
+\`\`\`
+AGENTS_LOCATIONS = [
+  { path: ".", type: "root" },
+  { path: "src/hooks", score: 18, reason: "high complexity" },
+  { path: "src/api", score: 12, reason: "distinct domain" }
+]
+\`\`\`
+
+**Mark "scoring" as completed.**
+
+---
+
+## Phase 3: Generate AGENTS.md
+
+**Mark "generate" as in_progress.**
+
+### Root AGENTS.md (Full Treatment)
+
+\`\`\`markdown
+# PROJECT KNOWLEDGE BASE
+
+**Generated:** {TIMESTAMP}
+**Commit:** {SHORT_SHA}
+**Branch:** {BRANCH}
+
+## OVERVIEW
+{1-2 sentences: what + core stack}

+
+## CODE MAP
+{From LSP - skip if unavailable or project <10 files}
+
+| Symbol | Type | Location | Refs | Role |
+|--------|------|----------|------|------|
+
+## CONVENTIONS
+{ONLY deviations from standard}
+
+## ANTI-PATTERNS (THIS PROJECT)
+{Explicitly forbidden here}
+
+## UNIQUE STYLES

+
+## COMMANDS
+\\\`\\\`\\\`bash
+{dev/test/build}
+\\\`\\\`\\\`
+
+## NOTES
+{Gotchas}
+\`\`\`
+
+**Quality gates**: 50-150 lines, no generic advice, no obvious info.
+
+### Subdirectory AGENTS.md (Parallel)
+
+Launch document-writer agents for each location:
+
+\`\`\`
+for loc in AGENTS_LOCATIONS (except root):
+  background_task(agent="document-writer", prompt=\\\`
+    Generate AGENTS.md for: \${loc.path}
+    - Reason: \${loc.reason}
+    - 30-80 lines max
+    - NEVER repeat parent content
+    - Sections: OVERVIEW (1 line), STRUCTURE (if >5 subdirs), WHERE TO LOOK, CONVENTIONS (if different), ANTI-PATTERNS
+  \\\`)
+\`\`\`
+
+**Wait for all. Mark "generate" as completed.**
+
+---
+
+## Phase 4: Review & Deduplicate
+
+**Mark "review" as in_progress.**
+
+For each generated file:
+- Remove generic advice
+- Remove parent duplicates
+- Trim to size limits
+- Verify telegraphic style
+
+**Mark "review" as completed.**
+
+---
+
+## Final Report
+
+\`\`\`
+=== init-deep Complete ===
+
+Mode: {update | create-new}
+
+Files:
+  ✓ ./AGENTS.md (root, {N} lines)
+  ✓ ./src/hooks/AGENTS.md ({N} lines)
+
+Dirs Analyzed: {N}
+AGENTS.md Created: {N}
+AGENTS.md Updated: {N}
+
+Hierarchy:
+  ./AGENTS.md
+  └── src/hooks/AGENTS.md
+\`\`\`
+
+---
+
+## Anti-Patterns
+
+- **Static agent count**: MUST vary agents based on project size/depth
+- **Sequential execution**: MUST parallel (explore + LSP concurrent)
+- **Ignoring existing**: ALWAYS read existing first, even with --create-new
+- **Over-documenting**: Not every dir needs AGENTS.md
+- **Redundancy**: Child never repeats parent
+- **Generic content**: Remove anything that applies to ALL projects
+- **Verbose style**: Telegraphic or die`

+export const RALPH_LOOP_TEMPLATE = `You are starting a Ralph Loop - a self-referential development loop that runs until task completion.
+
+## How Ralph Loop Works
+
+1. You will work on the task continuously
+2. When you believe the task is FULLY complete, output: \`<promise>{{COMPLETION_PROMISE}}</promise>\`
+3. If you don't output the promise, the loop will automatically inject another prompt to continue
+4. Maximum iterations: Configurable (default 100)
+
+## Rules
+
+- Focus on completing the task fully, not partially
+- Don't output the completion promise until the task is truly done
+- Each iteration should make meaningful progress toward the goal
+- If stuck, try different approaches
+- Use todos to track your progress
+
+## Exit Conditions
+
+1. **Completion**: Output \`<promise>DONE</promise>\` (or custom promise text) when fully complete
+2. **Max Iterations**: Loop stops automatically at limit
+3. **Cancel**: User runs \`/cancel-ralph\` command
+
+## Your Task
+
+Parse the arguments below and begin working on the task. The format is:
+\`"task description" [--completion-promise=TEXT] [--max-iterations=N]\`
+
+Default completion promise is "DONE" and default max iterations is 100.`
+
+export const CANCEL_RALPH_TEMPLATE = `Cancel the currently active Ralph Loop.
+
+This will:
+1. Stop the loop from continuing
+2. Clear the loop state file
+3. Allow the session to end normally
+
+Check if a loop is active and cancel it. Inform the user of the result.`

-## HOOK CATEGORIES
-
-| Category | Hooks | Purpose |
-|----------|-------|---------|
-| Context Injection | directory-agents-injector, directory-readme-injector, rules-injector, compaction-context-injector | Auto-inject relevant context |

-
-## HOW TO ADD A HOOK
-
-1. Create directory: `src/hooks/my-hook/`
-2. Create files:
-   - `index.ts`: Export `createMyHook(input: PluginInput)`
-   - `constants.ts`: Hook name constant
-   - `types.ts`: TypeScript interfaces (optional)
-   - `storage.ts`: Persistent state (optional)
-3. Return event handlers: `{ PreToolUse?, PostToolUse?, UserPromptSubmit?, Stop?, onSummarize? }`
-4. Export from `src/hooks/index.ts`
-5. Register in main plugin
-
 ## HOOK EVENTS
 
 | Event | Timing | Can Block | Use Case |
 |-------|--------|-----------|----------|
-| PreToolUse | Before tool exec | Yes | Validate, modify input |
-| PostToolUse | After tool exec | No | Add context, warnings |
-| UserPromptSubmit | On user prompt | Yes | Inject messages, block |
+| PreToolUse | Before tool | Yes | Validate, modify input |
+| PostToolUse | After tool | No | Add context, warnings |
+| UserPromptSubmit | On prompt | Yes | Inject messages, block |
 | Stop | Session idle | No | Inject follow-ups |
-| onSummarize | During compaction | No | Preserve critical context |
+| onSummarize | Compaction | No | Preserve context |
 
-## COMMON PATTERNS
+## HOW TO ADD
 
-- **Storage**: Use `storage.ts` with JSON file for persistent state across sessions
-- **Once-per-session**: Track injected paths in Set to avoid duplicate injection
-- **Message injection**: Return `{ messages: [...] }` from event handlers
-- **Blocking**: Return `{ blocked: true, message: "reason" }` from PreToolUse
+1. Create `src/hooks/my-hook/`
+2. Files: `index.ts` (createMyHook), `constants.ts`, `types.ts` (optional)
+3. Return: `{ PreToolUse?, PostToolUse?, UserPromptSubmit?, Stop?, onSummarize? }`
+4. Export from `src/hooks/index.ts`
 
-## ANTI-PATTERNS (HOOKS)
+## PATTERNS
 
-- **Heavy computation** in PreToolUse: Slows every tool call
-- **Blocking without clear reason**: Always provide actionable message
-- **Duplicate injection**: Track what's already injected per session
-- **Ignoring errors**: Always try/catch, log failures, don't crash session
+- **Storage**: JSON file for persistent state across sessions
+- **Once-per-session**: Track injected paths in Set
+- **Message injection**: Return `{ messages: [...] }`
+- **Blocking**: Return `{ blocked: true, message: "..." }` from PreToolUse
+
+## ANTI-PATTERNS
+
+- Heavy computation in PreToolUse (slows every tool call)
+- Blocking without actionable message
+- Duplicate injection (track what's injected)
+- Missing try/catch (don't crash session)
