fastapi-database-interaction

fastapi-database-interaction is a cursor rule for Cursor from holtwood/awesome-cursorrules-zh. It costs 0 tokens per session (71 once invoked), scanned A, original, MIT.

A set of rules for connecting FastAPI, a Python framework for building web APIs, to databases using asynchronous libraries such as asyncpg or aiomysql and SQLAlchemy 2.0.

In plain words
What is it for?
Use it when building FastAPI endpoints that read from or write to PostgreSQL or MySQL databases.
Why use it?
It helps prevent database calls from blocking other API requests and keeps database access consistent.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

fastapi-database-interaction scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

  • 推荐使用异步数据库库如 asyncpg 或 aiomysql
  • 如需 ORM 功能建议使用 SQLAlchemy 2.0
  • 最小化阻塞I/O操作,所有数据库调用都应使用异步方式

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
