## COMMANDS

| Command | Purpose | Key Logic |
|---------|---------|-----------|
| `install` | Interactive setup | Provider selection → config generation → plugin registration |
| `run` | Session launcher | Agent: flag → env → config → Sisyphus. Enforces todo completion. |
| `doctor` | 4-category health checks | system, config, tools, models (6 sub-checks) |
| `get-local-version` | Version check | Detects installed, compares with npm latest |
| `mcp-oauth` | OAuth tokens | login (PKCE flow), logout, status |

## RUN SESSION LIFECYCLE

1. Load config, resolve agent (CLI > env > config > Sisyphus)
2. Create server connection (port/attach), setup cleanup/signal handlers
3. Resolve session (create new or resume with retries)
4. Send prompt, start event processing, poll for completion
5. Execute on-complete hook, output JSON if requested, cleanup

## HOW TO ADD CHECK

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

## ANTI-PATTERNS

- **Blocking in non-TTY**: Check `process.stdout.isTTY`
- **Direct JSON.parse**: Use `parseJsonc()` from shared
- **Silent failures**: Return `warn` or `fail` in doctor, don't throw
- **Hardcoded paths**: Use `getOpenCodeConfigPaths()` from config-manager
