## CLI COMMANDS

| Command | Purpose |
|---------|---------|
| `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 CHECK CATEGORIES

| 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 function getMyCheckDefinition(): CheckDefinition {
     return {
       id: "my-check",
       name: "My Check",
       category: "configuration",
       check: async () => ({ status: "pass", message: "OK" })
     }
   }
   ```
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 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`
