# SysAdmin Agent Roadmap

This document tracks Agent-specific work for the AI SysAdmin system.

## Completed Work

### Core Infrastructure
- [x] Secure startup
- [x] Automatic registration with orchestrator
- [x] Polling loop (configurable interval)
- [x] Heartbeat loop
- [x] Executor registry system
- [x] BaseExecutor + ExecutionResult model
- [x] Logging with structlog
- [x] Sandboxing and path validation
- [x] Task timing, error propagation
- [x] Circuit breaker for resilience
- [x] Full test suite (140+ tests)

### Executors

| Executor | Purpose | Tests | Status |
|----------|---------|-------|--------|
| ECHO | Test connectivity | ✅ | Done |
| SHELL | Run allowed shell commands | ✅ | Done |
| ENV_UPDATE | Atomic env file edits | ✅ | Done |
| ENV_INSPECT | Read and parse env files | ✅ | Done |
| FILE_WRITE | Write files safely | ✅ | Done |
| FILE_INSPECT | Read files with size limits | 24 | Done |
| DOCKER_RELOAD | Pull + up -d compose stacks | 26 | Done |
| COMPOSITE | Chain multiple executors | ✅ | Done |
| NEXTCLOUD | Nextcloud-specific tasks | ✅ | Done |
| PLAYWRIGHT | Browser automation (stub) | - | Stub |

### Security
- [x] Path sandboxing to `/opt/letsbe/`
- [x] Allowed file root validation
- [x] Max file size limits
- [x] Shell command timeout
- [x] Non-root execution (configurable)

## Remaining Work

### Phase 1: Support for New Playbooks

No new executors needed - existing executors support all Phase 1 tool playbooks via COMPOSITE tasks.

---

### Phase 2: Introspection Executors

| Executor | Purpose | Status |
|----------|---------|--------|
| SERVICE_DISCOVER | List all running services/containers | ⬚ Todo |
| CONFIG_SCAN | Find misconfigurations across services | ⬚ Todo |
| NGINX_INSPECT | Parse nginx configs for domain info | ⬚ Todo |

---

### Phase 3: Server-Level Executors

| Executor | Purpose | Status |
|----------|---------|--------|
| NGINX_RELOAD | Validate and reload nginx | ⬚ Todo |
| HEALTHCHECK | Check docker status, ports, logs | ⬚ Todo |
| STACK_HEALTH | Verify docker compose stack integrity | ⬚ Todo |
| PACKAGE_UPGRADE | System package updates | ⬚ Todo |

**NGINX_RELOAD requirements:**
- Validate config with `nginx -t`
- Reload with `nginx -s reload`
- Rollback on failure
- Path sandboxing for config files

**HEALTHCHECK requirements:**
- Check container status via Docker API
- Verify expected ports are listening
- Scan logs for error patterns
- Return structured health report

---

### Phase 4: Advanced Executors

| Executor | Purpose | Status |
|----------|---------|--------|
| BACKUP | Create and upload backups | ⬚ Todo |
| RESTORE | Restore from backup | ⬚ Todo |
| LOG_TAIL | Stream logs from containers | ⬚ Todo |
| CERT_CHECK | Verify SSL certificate status | ⬚ Todo |

---

### Phase 5: Playwright Automation

Currently stubbed. Full implementation needs:

- [ ] Playwright installation in container
- [ ] Browser automation for initial tool setup
- [ ] Screenshot capture for verification
- [ ] Form filling for admin account creation

---

## Executor Implementation Pattern

All executors follow the same pattern:

```python
from app.executors.base import BaseExecutor, ExecutionResult

class NewExecutor(BaseExecutor):
    """Description of what this executor does."""

    async def execute(self, payload: dict) -> ExecutionResult:
        # 1. Validate payload
        # 2. Validate paths (if file operations)
        # 3. Perform operation
        # 4. Return ExecutionResult(success=True/False, data={...}, error=...)
```

Register in `app/executors/__init__.py`:
```python
from .new_executor import NewExecutor
EXECUTOR_REGISTRY["NEW_TYPE"] = NewExecutor
```

---

## Testing

All executors must have comprehensive tests:

```bash
# Run all tests
pytest

# Run specific executor tests
pytest tests/test_executors/test_new_executor.py -v

# Run with coverage
pytest --cov=app/executors
```

---

## Next Steps

1. Existing executors support Phase 1 - no changes needed
2. When Phase 2 starts, implement SERVICE_DISCOVER executor
3. When Phase 3 starts, implement NGINX_RELOAD and HEALTHCHECK
