python is a cursor rule for Cursor from flyeric0212/cursor-history-links. It costs 249 tokens per session, scanned A, original, MIT.

A set of rules for writing Python code, including current Python syntax, PEP 8 style, type hints, documentation, error handling, logging, and tests. PEP 8 is the commonly used style guide for Python.

In plain words
What is it for?
Use it when developing, debugging, documenting, or testing Python projects.
Why use it?
It gives an agent consistent expectations for readable, maintainable Python code. It also encourages checking the relevant code and investigating the cause of problems before making changes.

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 1mo 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.

Changes

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.
