## User Skills

| Skill | Trigger | Compact Rules |
|-------|---------|---------------|
| frontend-design | React components, HTML/CSS layouts, styling/beautifying web UI | Create production-grade frontend with high design quality. Choose a bold aesthetic direction. Implement real working code with typography, color, layout, spacing, and motion. Avoid generic AI aesthetics. |
| claude-api | Code imports `anthropic`/`@anthropic-ai/sdk`, Anthropic SDK, Claude API | Use official Anthropic SDK. Default to claude-opus-4-7. Use adaptive thinking. Stream long requests. Never mix OpenAI-compatible shims with Anthropic SDK. |
| webapp-testing | Testing local web apps, verifying frontend functionality, Playwright | Use native Python Playwright scripts. Run `scripts/with_server.py --help` for server lifecycle. Reconnaissance-then-action pattern. |

## Compact Rules

### frontend-design
- Use distinctive, characterful fonts (avoid Arial, Inter). Pair display + body fonts.
- Bold aesthetic direction: brutalist, editorial, organic, luxury, retro-futuristic, etc.
- Production-grade code: real components, real interactions, responsive.
- Meticulous details: border-radius, shadows, spacing, hover states, transitions.
- Never use placeholder lorem ipsum — use real content.

### claude-api
- Anthropic SDK: `import Anthropic from '@anthropic-ai/sdk'` (Node) or `from anthropic import Anthropic` (Python).
- Always use `anthropic.messages.create()` with `model`, `max_tokens`, `messages`, `system`.
- Streaming: set `stream: true`, iterate `stream` events.
- Prompt caching: add `cache_control: { type: "ephemeral" }` to system and last turn.
- Never use OpenAI-compatible endpoints for Anthropic models.

### webapp-testing
- Playwright scripts in Python. Install: `pip install playwright`.
- Use `with_server.py` helper for server lifecycle.
- Screenshot on failure for debugging.
- Wait for networkidle after navigation.
