## CLI COMMANDS
| Command | Purpose |
|---------|---------|
| `install` | Interactive setup wizard with subscription detection |
| `doctor` | Environment health checks (LSP, Auth, Config, Deps) |
| `run` | Launch OpenCode session with event handling |
| `auth` | Manage authentication providers |

## DOCTOR CHECKS
17+ checks in `doctor/checks/`:
- `version.ts`: OpenCode >= 1.0.150
- `config.ts`: Plugin registration & JSONC validity
- `dependencies.ts`: bun, node, git, gh-cli
- `auth.ts`: Anthropic, OpenAI, Google (Antigravity)
- `lsp.ts`, `mcp.ts`: Tool connectivity checks

## CONFIG-MANAGER
- **JSONC**: Supports comments and trailing commas via `parseJsonc`
- **Multi-source**: Merges User (`~/.config/opencode/`) + Project (`.opencode/`)
- **Validation**: Strict Zod schema with error aggregation for `doctor`
- **Env**: Detects `OPENCODE_CONFIG_DIR` for profile isolation

## HOW TO ADD CHECK
1. Create `src/cli/doctor/checks/my-check.ts` returning `DoctorCheck`
2. Export from `checks/index.ts` and add to `getAllCheckDefinitions()`
3. Use `CheckContext` for shared utilities (LSP, Auth)

## ANTI-PATTERNS
- Blocking prompts in non-TTY (check `process.stdout.isTTY`)
- Direct `JSON.parse` (breaks JSONC compatibility)
- Silent failures (always return `warn` or `fail` in `doctor`)
- Environment-specific hardcoding (use `ConfigManager`)
