Build fast, production-ready Python APIs with type hints, validation, and async support.
# FastAPI Patterns
## 异步 Traps - Mixing sync 数据库 drivers (psycopg2, PyMySQL) in 异步 endpoints blocks the 事件循环 — use 异步 drivers (asyncpg, aiomysql) or 运行 sync code in `run_in_executor` - `time.sleep()` in 异步 endpoints blocks everything — use `等待 asyncio.sleep()` instead - CPU-bound work in 异步 endpoi
Stop waiting for prompts. Keep working.
Build high-performing OpenClaw agents end-to-end. Use when you want to design a new agent (persona + operating rules) and generate the required OpenClaw workspace files (SOUL.md, IDENTITY.md, AGENTS.md, USER.md, HEARTBEAT.md, optional MEMORY.md + memory/YYYY-MM-DD.md). Also use to iterate on an existing agent’s behavior, guardrails, autonomy model, heartbeat plan, and skill roster.
Safe content workflow (drafts/reviewed/revised/approved/posted) with human-in-the-loop approval, plus CLI to list/move/review and post to LinkedIn/X. Use when setting up a content pipeline, drafting content, managing review threads, or posting approved content.
