chen-python-skills

chen-python-skills is a skill for Claude Code, Codex from cyj4578/chen-skillshub. It costs 169 tokens per session (925 once invoked), scanned A, original, MIT.

A Chinese-language reference library for core Python programming topics. It covers syntax, data types, functions, classes, files, errors, type hints, and common standard-library modules.

In plain words
What is it for?
Use it to check Python syntax, write functions and classes, work with collections and files, handle exceptions, and use modules such as JSON and datetime.
Why use it?
It gives developers a single index for looking up everyday Python concepts without searching through many separate references.

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

chen-python-skills 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 5d 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.

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
