Skills

A skill is a package of structured files that teaches an AI coding agent how to work with a specific tool or framework. Install it in your agent and it will be able to run commands, edit configuration, write content, and troubleshoot problems without step-by-step guidance from you.

Any agent — install with npx:

npx skills add https://example.com/gdtest-skill-combo/

Codex / OpenCode

Tell the agent:
Fetch the skill file at https://example.com/gdtest-skill-combo/skill.md and follow the instructions.

Manual — download the skill file:

curl -O https://example.com/gdtest-skill-combo/skill.md

Or browse the SKILL.md file.

# gdtest-skill-combo

A lightweight, composable API router toolkit.

## Quick start

```python
from gdtest_skill_combo import Router, route

app = Router(prefix="/api/v1")

@route("GET", "/users")
def list_users(req):
    return Response(body='[{"name": "Alice"}]')

app.get("/users", list_users)
```

## When to use what

| Need | Use |
|------|-----|
| Simple sync API | `Router()` |
| Async handlers | `AsyncRouter()` |
| Add middleware | `router.use(fn)` |
| Serve static files | `router.static(url, dir)` |
| Decorate handlers | `@route("GET", "/path")` |
| Inject dependencies | `Router(deps={"db": db})` |

## Middleware

Middleware functions wrap request processing. They run in
**LIFO order** (last added runs first):

```python
def logging_middleware(req, next_handler):
    print(f"{req.method} {req.path}")
    return next_handler(req)

router.use(logging_middleware)
```

## Capabilities and boundaries

**What agents can configure:**

- Create routers with route registration
- Add middleware and dependency injection
- Serve static files
- Use async handlers for concurrent processing

**Requires human setup:**

- Deploying behind a production ASGI/WSGI server
- TLS certificate configuration
- Database connection setup
