## COMMANDS

| Command | Purpose |
|---------|---------|
| `install` | Interactive setup with provider selection |
| `doctor` | 14 health checks for diagnostics |
| `run` | Launch session with todo enforcement |
| `get-local-version` | Version detection and update check |

## DOCTOR CATEGORIES (14 Checks)

| Category | Checks |
|----------|--------|
| installation | opencode, plugin |
| configuration | config validity, Zod, model-resolution |
| authentication | anthropic, openai, google |
| dependencies | ast-grep, comment-checker, gh-cli |
| tools | LSP, MCP |
| updates | version comparison |

## HOW TO ADD CHECK

1. Create `src/cli/doctor/checks/my-check.ts`
2. Export `getXXXCheckDefinition()` factory returning `CheckDefinition`
3. Add to `getAllCheckDefinitions()` in `checks/index.ts`

## TUI FRAMEWORK

- **@clack/prompts**: `select()`, `spinner()`, `intro()`, `outro()`
- **picocolors**: Terminal colors for status and headers
- **Symbols**: ✓ (pass), ✗ (fail), ⚠ (warn), ℹ (info)

## 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`
