python-guidelines SKILL.md skillA
python-guidelines from fcakyon/claude-codex-settings is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add fcakyon/claude-codex-settings/python-guidelines@git:20260724.ef71714Pins git:20260724.ef71714 in mdr.lock. Pin the fingerprint instead.

This skill should be used when writing, reviewing, or refactoring Python code. Covers code integration, idiomatic patterns, docstring formatting, anti-abstraction rules, and software engineering basics.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Python Guidelines
**Integrate into existing code. Don't append to it.**
> Simple is better than complex. Flat is better than nested.
> Errors should never pass silently. Unless explicitly silenced.
> If the implementation is hard to explain, it's a bad idea.
>
> -- The Zen of Python (PEP 20)
## Code Philosophy
- Match existing naming, importing, and signature patterns. Use existing utilities and data structures.
- Functions have a single purpose. Don't hardcode behavior that makes them less general.
- No trivial wrappers for 2 lines or less. Inline it.
- Inline single-use variables at the usage site.
- No try/except unless critical. Let errors surface.
- No duplicate code.
- Functions handle their own input validation. No if-else checks in main.
- Use pathlib, not os.path.
- Consider API and time costs for MongoDB/Gemini/OpenAI/Claude/Voyage.
Don't do this:
```python
# Generate comment report only if requested
if include_comments:
comment_report = generate_comments_report(start_date, end_date, team, verbose)
else:
comment_report = ""
print(" Skipping comment analysis (disabled)")
```
Do this:
```python
…Read the whole file at its exact version.
How to install
mdr add fcakyon/claude-codex-settings/python-guidelines@sha256:85b836dd2e8e6613The line at the top of this page pins the label git:20260724.ef71714, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
