python SKILL.md skillA

python from dayfinggg/openai-codex-agent-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add dayfinggg/openai-codex-agent-skills/python@git:20261105.e0d5bb2

Implements and tests Python changes with interpreter, typing, packaging, and asyncio checks. Use when editing or creating .py files, Python scripts or packages, pytest or unittest tests, pyproject.toml, or when the user mentions Python, Django, FastAPI, mypy, or a Python environment mismatch.

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

1. Before editing, run `python --version` through the project's environment runner and `python -c "import sys; print(sys.executable); print(sys.prefix)"`. Read `pyproject.toml`, existing requirements or lockfiles, `.python-version`, test settings, and CI. Establish the minimum supported Python, build backend, dependency groups, and installed framework versions. `requires-python` constrains installation, classifiers do not. Read version-matched documentation for changed Django, FastAPI, SQLAlchemy, or stdlib APIs.

2. For implementation or dependency work, read [the shared procedure](references/common.md). For a version-only question, inspect the environment without installing or updating packages. Use `python -m pip show PACKAGE` in pip environments, or the existing manager's installed-package inspection. A lockfile records resolution, not proof of what the active interpreter imports.

How to install

The exact contents, by fingerprint

mdr add dayfinggg/openai-codex-agent-skills/python@sha256:84a5608f8a2fe203

The line at the top of this page pins the label git:20261105.e0d5bb2, 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.
