 ## TDD (Test-Driven Development)
 
 **MANDATORY for new features and bug fixes.** Follow RED-GREEN-REFACTOR:
 
-```
-1. RED    - Write failing test first (test MUST fail)
-2. GREEN  - Write MINIMAL code to pass (nothing more)
-3. REFACTOR - Clean up while tests stay GREEN
-4. REPEAT - Next test case
-```
-
 | Phase | Action | Verification |
 |-------|--------|--------------|
-| **RED** | Write test describing expected behavior | `bun test` -> FAIL (expected) |
-| **GREEN** | Implement minimum code to pass | `bun test` -> PASS |
-| **REFACTOR** | Improve code quality, remove duplication | `bun test` -> PASS (must stay green) |
+| **RED** | Write test describing expected behavior | `bun test` → FAIL (expected) |
+| **GREEN** | Implement minimum code to pass | `bun test` → PASS |
+| **REFACTOR** | Improve code quality, remove duplication | `bun test` → PASS (must stay green) |
 
 **Rules:**
 - NEVER write implementation before test
 - NEVER delete failing tests to "pass" - fix the code
-- One test at a time - don't batch
 - Test file naming: `*.test.ts` alongside source
 - BDD comments: `#given`, `#when`, `#then` (same as AAA)

-- **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
-- **High temperature**: Don't use >0.3 for code-related agents
-- **Broad tool access**: Prefer explicit `include` over unrestricted access
-- **Sequential agent calls**: Use `sisyphus_task` for parallel execution
-- **Heavy PreToolUse logic**: Slows every tool call
-- **Self-planning for complex tasks**: Spawn planning agent (Prometheus) instead
-- **Trust agent self-reports**: ALWAYS verify results independently
-- **Skip TODO creation**: Multi-step tasks MUST have todos first
-- **Batch completions**: Mark TODOs complete immediately, don't group
-- **Giant commits**: 3+ files = 2+ commits minimum
-- **Separate test from impl**: Same commit always
+| Category | Forbidden |
+|----------|-----------|
+| **Package Manager** | npm, yarn - use Bun exclusively |
+| **Types** | @types/node - use bun-types |
+| **File Ops** | mkdir/touch/rm/cp/mv in code - agents use bash tool |
+| **Publishing** | Direct `bun publish` - use GitHub Actions workflow_dispatch |
+| **Versioning** | Local version bump - managed by CI |
+| **Date References** | Year 2024 - use current year |
+| **Type Safety** | `as any`, `@ts-ignore`, `@ts-expect-error` |
+| **Error Handling** | Empty catch blocks `catch(e) {}` |
+| **Testing** | Deleting failing tests to "pass" |
+| **Agent Calls** | Sequential agent calls - use `delegate_task` for parallel |
+| **Tool Access** | Broad tool access - prefer explicit `include` |
+| **Hook Logic** | Heavy PreToolUse computation - slows every tool call |
+| **Commits** | Giant commits (3+ files = 2+ commits), separate test from impl |
+| **Temperature** | >0.3 for code agents |
+| **Trust** | Trust agent self-reports - ALWAYS verify independently |
 
 ## 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
 - **Factory pattern**: Components created via `createXXX()` functions

+2. **Claude Code compatible**: `.mcp.json` files with `${VAR}` expansion
+3. **Skill-embedded**: YAML frontmatter in skills (e.g., playwright)
+
+## CONFIG SYSTEM
+
+- **Zod validation**: `src/config/schema.ts`
+- **JSONC support**: Comments and trailing commas
+- **Multi-level**: Project (`.opencode/`) → User (`~/.config/opencode/`)
+- **CLI doctor**: Validates config and reports errors
 
 ## NOTES
 
-- **Testing**: Bun native test (`bun test`), BDD-style `#given/#when/#then`, 76 test files
+- **Testing**: Bun native test (`bun test`), BDD-style, 84 test files
 - **OpenCode**: Requires >= 1.0.150
 - **Multi-lang docs**: README.md (EN), README.ko.md (KO), README.ja.md (JA), README.zh-cn.md (ZH-CN)
 - **Config**: `~/.config/opencode/oh-my-opencode.json` (user) or `.opencode/oh-my-opencode.json` (project)
 - **Trusted deps**: @ast-grep/cli, @ast-grep/napi, @code-yeongyu/comment-checker
-- **JSONC support**: Config files support comments (`// comment`, `/* block */`) and trailing commas
 - **Claude Code Compat**: Full compatibility layer for settings.json hooks, commands, skills, agents, MCPs
-- **Skill MCP**: Skills can embed MCP server configs in YAML frontmatter
+- **Flaky tests**: 2 known flaky tests (ralph-loop CI timeout, session-state parallel pollution)

+# Claude OAuth アクセスに関するお知らせ
+
+## TL;DR
+
+> Q. oh-my-opencodeを使用できますか？
+
+はい。
+
+> Q. Claude Codeのサブスクリプションで使用できますか？
+
+はい、技術的には可能です。ただし、使用を推奨することはできません。
+
+## 詳細
+
+> 2026年1月より、AnthropicはToS違反を理由にサードパーティのOAuthアクセスを制限しました。
+>
+> [**Anthropicはこのプロジェクト oh-my-opencode を、opencodeをブロックする正当化の根拠として挙げています。**](https://x.com/thdxr/status/2010149530486911014)
+>
+> 実際、Claude CodeのOAuthリクエストシグネチャを偽装するプラグインがコミュニティに存在します。
+>
+> これらのツールは技術的な検出可能性に関わらず動作する可能性がありますが、ユーザーはToSへの影響を認識すべきであり、私個人としてはそれらの使用を推奨できません。
+>
+> このプロジェクトは非公式ツールの使用に起因するいかなる問題についても責任を負いません。また、**私たちはそれらのOAuthシステムのカスタム実装を一切持っていません。**

+## TL;DR
 
-**Certified, Verified, Tested, Actually Useful Harness in Production, after $24,000 worth of tokens spent.**
-**START WITH YOUR ChatGPT, Claude, Gemini SUBSCRIPTIONS. WE ALL COVER THEM.**
+> Q. Can I use oh-my-opencode?
+
+Yes.
+
+> Q. Can I use it with my Claude Code subscription?
+
+Yes, technically possible. But I cannot recommend using it.
+
+## FULL
+
+> As of January 2026, Anthropic has restricted third-party OAuth access citing ToS violations.
+> 
+> [**Anthropic has cited this project, oh-my-opencode as justification for blocking opencode.**](https://x.com/thdxr/status/2010149530486911014)
+>
+> Indeed, some plugins that spoof Claude Code's oauth request signatures exist in the community.
+>
+> These tools may work regardless of technical detectability, but users should be aware of ToS implications, and I personally cannot recommend to use those.
+>
+> This project is not responsible for any issues arising from the use of unofficial tools, and **we do not have any custom implementations of those oauth systems.**

 **Note on `auto-update-checker` and `startup-toast`**: The `startup-toast` hook is a sub-feature of `auto-update-checker`. To disable only the startup toast notification while keeping update checking enabled, add `"startup-toast"` to `disabled_hooks`. To disable all update checking features (including the toast), add `"auto-update-checker"` to `disabled_hooks`.

-## HOW TO ADD AN AGENT
+## HOW TO ADD
 
-1. Create `src/agents/my-agent.ts`:
-   ```typescript
-   import type { AgentConfig } from "@opencode-ai/sdk"
-   
-   export const myAgent: AgentConfig = {
-     model: "provider/model-name",
-     temperature: 0.1,
-     system: "Agent system prompt...",
-     tools: { include: ["tool1", "tool2"] },  // or exclude: [...]
-   }
-   ```
+1. Create `src/agents/my-agent.ts` exporting `AgentConfig`
 2. Add to `builtinAgents` in `src/agents/index.ts`
-3. Update `types.ts` if adding new config options
+3. Update `AgentNameSchema` in `src/config/schema.ts`
+4. Register in `src/index.ts` initialization
 
-## AGENT CONFIG OPTIONS
+## TOOL RESTRICTIONS
 
-| Option | Type | Description |
-|--------|------|-------------|
-| model | string | Model identifier (provider/model-name) |
-| temperature | number | 0.0-1.0, most use 0.1 for consistency |
-| system | string | System prompt (can be multiline template literal) |
-| tools | object | `{ include: [...] }` or `{ exclude: [...] }` |
-| top_p | number | Optional nucleus sampling |
-| maxTokens | number | Optional max output tokens |
+| Agent | Denied Tools |
+|-------|-------------|
+| oracle | write, edit, task, delegate_task |
+| librarian | write, edit, task, delegate_task, call_omo_agent |
+| explore | write, edit, task, delegate_task, call_omo_agent |
+| multimodal-looker | Allowlist: read, glob, grep |
 
-## MODEL FALLBACK LOGIC
+## KEY PATTERNS
 
-`createBuiltinAgents()` in utils.ts handles model fallback:
+- **Factory**: `createXXXAgent(model?: string): AgentConfig`
+- **Metadata**: `XXX_PROMPT_METADATA: AgentPromptMetadata`
+- **Tool restrictions**: `permission: { edit: "deny", bash: "ask" }`
+- **Thinking**: 32k budget tokens for Sisyphus, Oracle, Prometheus
 
-1. Check user config override (`agents.{name}.model`)
-2. Check installer settings (claude max20, gemini antigravity)
-3. Use default model
+## ANTI-PATTERNS
 
-**Fallback order for explore**:
-- If gemini antigravity enabled → `google/gemini-3-flash`
-- If claude max20 enabled → `anthropic/claude-haiku-4-5`
-- Default → `opencode/grok-code` (free)
-
-## ANTI-PATTERNS (AGENTS)
-
-- **High temperature**: Don't use >0.3 for code-related agents
-- **Broad tool access**: Prefer explicit `include` over unrestricted access
-- **Monolithic prompts**: Keep prompts focused; delegate to specialized agents
-- **Missing fallbacks**: Consider free/cheap fallbacks for rate-limited models
-
-## SHARED PROMPTS
-
-- **build-prompt.ts**: Base prompt for build agents (OpenCode default + Sisyphus variants)
-- **plan-prompt.ts**: Base prompt for plan agents (legacy)
-- **prometheus-prompt.ts**: System prompt for Prometheus (Planner) agent
-- **metis.ts**: Metis (Plan Consultant) agent for pre-planning analysis
-
-Used by `src/index.ts` when creating Builder-Sisyphus and Prometheus (Planner) variants.
+- **Trust reports**: NEVER trust subagent "I'm done" - verify outputs
+- **High temp**: Don't use >0.3 for code agents
+- **Sequential calls**: Use `delegate_task` with `run_in_background`

-## ABSOLUTE CONSTRAINTS (NON-NEGOTIABLE)
-
-### 1. NO IMPLEMENTATION - PLANNING ONLY
-You are a PLANNER, NOT an executor. You must NEVER:
-- Start implementing ANY task
-- Write production code
-- Execute the work yourself
-- "Get started" on any implementation
-- Begin coding even if user asks
-
-Your ONLY job is to CREATE THE PLAN. Implementation is done by OTHER agents AFTER you deliver the plan.
-If user says "implement this" or "start working", you respond: "I am the plan agent. I will create a detailed work plan for execution by other agents."
-
-### 2. READ-ONLY FILE ACCESS
-You may NOT create or edit any files. You can only READ files for context gathering.
-- Reading files for analysis: ALLOWED
-- ANY file creation or edits: STRICTLY FORBIDDEN
-
-### 3. PLAN OUTPUT
-Your deliverable is a structured work plan delivered directly in your response.
-You do NOT deliver code. You do NOT deliver implementations. You deliver PLANS.
-
-ZERO EXCEPTIONS to these constraints.
-</system-reminder>
-
-You are a strategic planner. You bring foresight and structure to complex work.
-
-## Your Mission
-
-Create structured work plans that enable efficient execution by AI agents.
-
-## Workflow (Execute Phases Sequentially)
-
-### Phase 1: Context Gathering (Parallel)
-
-Launch **in parallel**:
-
-**Explore agents** (3-5 parallel):
-\`\`\`
-Task(subagent_type="explore", prompt="Find [specific aspect] in codebase...")
-\`\`\`
-- Similar implementations
-- Project patterns and conventions
-- Related test files
-- Architecture/structure
-
-**Librarian agents** (2-3 parallel):
-\`\`\`
-Task(subagent_type="librarian", prompt="Find documentation for [library/pattern]...")
-\`\`\`
-- Framework docs for relevant features
-- Best practices for the task type
-
-### Phase 2: AI Slop Guardrails
-
-Call \`Metis (Plan Consultant)\` with gathered context to identify guardrails:
-
-\`\`\`
-Task(
-  subagent_type="Metis (Plan Consultant)",
-  prompt="Based on this context, identify AI slop guardrails:
-
-  User Request: {user's original request}
-  Codebase Context: {findings from Phase 1}
-
-  Generate:
-  1. AI slop patterns to avoid (over-engineering, unnecessary abstractions, verbose comments)
-  2. Common AI mistakes for this type of task
-  3. Project-specific conventions that must be followed
-  4. Explicit 'MUST NOT DO' guardrails"
-)
-\`\`\`
-
-### Phase 3: Plan Generation
-
-Generate a structured plan with:
-
-1. **Core Objective** - What we're achieving (1-2 sentences)
-2. **Concrete Deliverables** - Exact files/endpoints/features
-3. **Definition of Done** - Acceptance criteria
-4. **Must Have** - Required elements
-5. **Must NOT Have** - Forbidden patterns (from Metis guardrails)
-6. **Task Breakdown** - Sequential/parallel task flow
-7. **References** - Existing code to follow
-
-## Key Principles
-
-1. **Infer intent from context** - Use codebase patterns and common practices
-2. **Define concrete deliverables** - Exact outputs, not vague goals
-3. **Clarify what NOT to do** - Most important for preventing AI mistakes
-4. **References over instructions** - Point to existing code
-5. **Verifiable acceptance criteria** - Commands with expected outputs
-6. **Implementation + Test = ONE task** - NEVER separate
-7. **Parallelizability is MANDATORY** - Enable multi-agent execution

+|----------|--------|---------|
+| **CRITICAL: Requires User Input** | ASK immediately | Business logic choice, tech stack preference, unclear requirement |
+| **MINOR: Can Self-Resolve** | FIX silently, note in summary | Missing file reference found via search, obvious acceptance criteria |

-"Before I generate the final plan:
-
-**Do you need high accuracy?**
-
-If yes, I'll have Momus (our rigorous plan reviewer) meticulously verify every detail of the plan.
-Momus applies strict validation criteria and won't approve until the plan is airtight—no ambiguity, no gaps, no room for misinterpretation.
-This adds a review loop, but guarantees a highly precise work plan that leaves nothing to chance.
-
-If no, I'll generate the plan directly based on our discussion."
+□ All TODO items have concrete acceptance criteria?
+□ All file references exist in codebase?
+□ No assumptions about business logic without evidence?
+□ Guardrails from Metis review incorporated?
+□ Scope boundaries clearly defined?

+### Gap Handling Protocol
+
+<gap_handling>
+**IF gap is CRITICAL (requires user decision):**
+1. Generate plan with placeholder: \`[DECISION NEEDED: {description}]\`
+2. In summary, list under "⚠️ Decisions Needed"
+3. Ask specific question with options
+4. After user answers → Update plan silently → Continue

-3. **User Controls Transition** - NEVER generate plan until explicitly requested
-4. **Metis Before Plan** - Always catch gaps before committing to plan

-Frontend files (.tsx, .jsx, .vue, .svelte, .css, etc.) require **classification before action**.
+**DEFAULT ASSUMPTION**: Any frontend file change is VISUAL until proven otherwise.
 
-#### Step 1: Classify the Change Type
+#### HARD BLOCK: Visual Changes (NEVER touch directly)
 
-| Change Type | Examples | Action |
-|-------------|----------|--------|
-| **Visual/UI/UX** | Color, spacing, layout, typography, animation, responsive breakpoints, hover states, shadows, borders, icons, images | **DELEGATE** to \`frontend-ui-ux-engineer\` |
-| **Pure Logic** | API calls, data fetching, state management, event handlers (non-visual), type definitions, utility functions, business logic | **CAN handle directly** |
-| **Mixed** | Component changes both visual AND logic | **Split**: handle logic yourself, delegate visual to \`frontend-ui-ux-engineer\` |
+| Pattern | Action | No Exceptions |
+|---------|--------|---------------|
+| \`.tsx\`, \`.jsx\` with styling | DELEGATE | Even "just add className" |
+| \`.vue\`, \`.svelte\` | DELEGATE | Even single prop change |
+| \`.css\`, \`.scss\`, \`.sass\`, \`.less\` | DELEGATE | Even color/margin tweak |
+| Any file with visual keywords | DELEGATE | See keyword list below |
 
-#### Step 2: Ask Yourself
+#### Keyword Detection (INSTANT DELEGATE)
 
-Before touching any frontend file, think:
-> "Is this change about **how it LOOKS** or **how it WORKS**?"
+If your change involves **ANY** of these keywords → **STOP. DELEGATE.**
 
-- **LOOKS** (colors, sizes, positions, animations) → DELEGATE
-- **WORKS** (data flow, API integration, state) → Handle directly

+hover, responsive, font-size, font-weight, icon, svg, image, layout,
+position, display, opacity, z-index, transform, gradient, theme
+\`\`\`
 
-#### When in Doubt → DELEGATE if ANY of these keywords involved:
-style, className, tailwind, color, background, border, shadow, margin, padding, width, height, flex, grid, animation, transition, hover, responsive, font-size, icon, svg`
+**YOU CANNOT**:
+- "Just quickly fix this style"
+- "It's only one className"
+- "Too simple to delegate"
+
+#### EXCEPTION: Pure Logic Only
+
+You MAY handle directly **ONLY IF ALL** conditions are met:
+1. Change is **100% logic** (API, state, event handlers, types, utils)
+2. **Zero** visual keywords in your diff
+3. No styling, layout, or appearance changes whatsoever
+
+| Pure Logic Examples | Visual Examples (DELEGATE) |
+|---------------------|---------------------------|
+| Add onClick API call | Change button color |
+| Fix pagination logic | Add loading spinner animation |
+| Add form validation | Make modal responsive |
+| Update state management | Adjust spacing/margins |
+
+#### Mixed Changes → SPLIT
+
+If change has BOTH logic AND visual:
+1. Handle logic yourself
+2. DELEGATE visual part to \`frontend-ui-ux-engineer\`

-
-## 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)

- * - **Debug logs**: Guard with `if (process.env.ANTIGRAVITY_DEBUG === "1")`
- *   - Includes: info messages, warnings, non-fatal errors
- *   - Enable debugging: `ANTIGRAVITY_DEBUG=1 opencode`

-You are Antigravity, a powerful agentic AI coding assistant designed by the Google Deepmind team working on Advanced Agentic Coding.
-You are pair programming with a USER to solve their coding task. The task may require creating a new codebase, modifying or debugging an existing codebase, or simply answering a question.
-The USER will send you requests, which you must always prioritize addressing. Along with each USER request, we will attach additional metadata about their current state, such as what files they have open and where their cursor is.
-This information may or may not be relevant to the coding task, it is up for you to decide.

-<tool_calling>
-Call tools as you normally would. The following list provides additional guidance to help you avoid errors:
-  - **Absolute paths only**. When using tools that accept file path arguments, ALWAYS use the absolute file path.
-</tool_calling>
-
-<web_application_development>
-## Technology Stack
-Your web applications should be built using the following technologies:
-1. **Core**: Use HTML for structure and Javascript for logic.
-2. **Styling (CSS)**: Use Vanilla CSS for maximum flexibility and control. Avoid using TailwindCSS unless the USER explicitly requests it; in this case, first confirm which TailwindCSS version to use.
-3. **Web App**: If the USER specifies that they want a more complex web app, use a framework like Next.js or Vite. Only do this if the USER explicitly requests a web app.
-4. **New Project Creation**: If you need to use a framework for a new app, use \`npx\` with the appropriate script, but there are some rules to follow:
-   - Use \`npx -y\` to automatically install the script and its dependencies
-   - You MUST run the command with \`--help\` flag to see all available options first
-   - Initialize the app in the current directory with \`./\` (example: \`npx -y create-vite-app@latest ./\`)

-/**
- * Antigravity Fetch Interceptor
- *
- * Creates a custom fetch function that:
- * - Checks token expiration and auto-refreshes
- * - Rewrites URLs to Antigravity endpoints
- * - Applies request transformation (including tool normalization)
- * - Applies response transformation (including thinking extraction)
- * - Implements endpoint fallback (daily → autopush → prod)
- *
- * **Body Type Assumption:**
- * This interceptor assumes `init.body` is a JSON string (OpenAI format).
- * Non-string bodies (ReadableStream, Blob, FormData, URLSearchParams, etc.)
- * are passed through unchanged to the original fetch to avoid breaking
- * other requests that may not be OpenAI-format API calls.
- *
- * Debug logging available via ANTIGRAVITY_DEBUG=1 environment variable.

 ## CLI COMMANDS
 
 | Command | Purpose |
 |---------|---------|
-| `install` | Interactive setup wizard |
-| `doctor` | Environment health checks |
-| `run` | Launch OpenCode session |
+| `install` | Interactive setup, subscription detection |
+| `doctor` | 14 health checks, `--verbose`, `--json`, `--category` |
+| `run` | Launch OpenCode session with completion enforcement |
+| `get-local-version` | Version detection, update checking |
 
-## DOCTOR CHECKS
+## DOCTOR CHECK CATEGORIES
 
-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
+| Category | Checks |
+|----------|--------|
+| installation | opencode, plugin registration |
+| configuration | config validity, Zod validation |
+| authentication | anthropic, openai, google |
+| dependencies | ast-grep CLI/NAPI, comment-checker |
+| tools | LSP, MCP connectivity |
+| updates | version comparison |
 
 ## 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: "..." }
+   export function getMyCheckDefinition(): CheckDefinition {
+     return {
+       id: "my-check",
+       name: "My Check",
+       category: "configuration",
+       check: async () => ({ status: "pass", message: "OK" })
      }
    }
    ```
-2. Add to `src/cli/doctor/checks/index.ts`
+2. Export from `checks/index.ts`
+3. Add to `getAllCheckDefinitions()`
+
+## TUI FRAMEWORK
+
+- **@clack/prompts**: `select()`, `spinner()`, `intro()`, `outro()`, `note()`
+- **picocolors**: Colored terminal output
+- **Symbols**: ✓ (pass), ✗ (fail), ⚠ (warn), ○ (skip)
+
+## CONFIG-MANAGER
+
+- **JSONC**: Comments (`// ...`), block comments, trailing commas
+- **Multi-source**: User (`~/.config/opencode/`) + Project (`.opencode/`)
+- **Env override**: `OPENCODE_CONFIG_DIR` for profile isolation
+- **Validation**: Zod schema with error aggregation
 
 ## 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
+- **Blocking in non-TTY**: Check `process.stdout.isTTY`
+- **Direct JSON.parse**: Use `parseJsonc()` for config
+- **Silent failures**: Always return warn/fail in doctor
+- **Hardcoded paths**: Use `ConfigManager`
