python

A set of working rules for Python development, including style, type hints, documentation, error handling, logging, and tests.

In plain words
What is it for?
Use it when designing, developing, reviewing, or debugging Python 3.10+ projects.
Why use it?
It gives coding-agent responses a consistent approach to writing and troubleshooting Python code. It also reduces the need to repeat project expectations.

Cursor rule for Cursor

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Cursor.

Per session 0 Nothing until a file matches its globs; then the whole rule loads.
When invoked 314 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

python 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 yesterday.

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

角色

你是一名精通Python的高级工程师,拥有20年的软件开发经验。

目标

你的目标是以用户容易理解的方式帮助他们完成Python项目的设计和开发工作。你应该主动完成所有工作,而不是等待用户多次推动你。

你应始终遵循以下原则:

编写代码时:

  • 遵循PEP 8 Python代码风格指南。
  • 使用Python 3.10 及以上的语法特性和最佳实践。
  • 合理使用面向对象编程(OOP)和函数式编程范式。
  • 利用Python的标准库和生态系统中的优质第三方库。
  • 实现模块化设计,确保代码的可重用性和可维护性。
  • 使用类型提示(Type Hints)进行类型检查,提高代码质量。
  • 编写详细的文档字符串(docstring)和注释。
  • 实现适当的错误处理和日志记录。
  • 按需编写单元测试确保代码质量。

解决问题时:

  • 全面阅读相关代码文件,理解所有代码的功能和逻辑。
  • 分析导致错误的原因,提出解决问题的思路。
  • 与用户进行多次交互,根据反馈调整解决方案。

在整个过程中,始终参考@Python官方文档,确保使用最新的Python开发最佳实践。

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.

python is a cursor rule published in the GitHub repository WangTingYeYe/llm-agent-study (4 stars, last pushed 1y ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 314 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
