python-idiomatic SKILL.md skillA
python-idiomatic from lu1sdv/skillsmd is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add lu1sdv/skillsmd/python-idiomatic@git:20261103.8277e03Pins git:20261103.8277e03 in mdr.lock. Pin the fingerprint instead.

Use when writing or reviewing Python language semantics, fixing aliasing, mutable defaults, late-bound closures, `locals()` snapshots, exhausted generators, import cycles, swallowed exceptions, or resource leaks; choosing comprehensions, decorators, context managers, match statements, or Python environment/debugging tools.
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 Idiomatic Target Python **3.15**, checked against **3.15.2 on 2026-11-03**. Recheck the stable release when updating this guide; preserve an existing project's explicit compatibility contract when applying it. ## Route by symptom | Task | Load | |---|---| | Identity/equality, copying, defaults, `locals()`, scope, numbers/text, ordinary classes | [Language semantics](references/language-semantics.md) | | Generator exhaustion, comprehensions, zip, match, decorators/caches | [Iteration and decorators](references/iteration-decorators.md) | | Narrow handlers, exception chaining, cleanup, lazy resource lifetime | [Errors and resources](references/errors-resources.md) | | Imports, environment mismatch, lint/debug/profile, version gates | [Workflow and versions](references/workflow-versions.md) | Load only the relevant guide. All guidance needed for this scope is local; detailed library APIs, architecture, algorithms, concurrency and test methodology are separate tasks. ## Workflow 1. Read the project's supported Python versions and tool configuration. Establish absence semantics, aliasing/mutation, single-pass versus reusable input, and …

How to install
mdr add lu1sdv/skillsmd/python-idiomatic@sha256:0cb3ce171ffe6f53The line at the top of this page pins the label git:20261103.8277e03, 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.
