python-stdlib SKILL.md skillA
python-stdlib 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-stdlib@git:20261103.8277e03Pins git:20261103.8277e03 in mdr.lock. Pin the fingerprint instead.

Use when choosing or debugging Python standard-library APIs for iteration, caching, files, timestamps, JSON/CSV/TOML, regex, logging, dataclasses, resource cleanup, subprocesses, or AST-based source analysis, especially versioned parser, boundary and data-loss bugs.
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 Standard Library ## Quick reference: routing | Task / symptom | Read | |---|---| | Counting, grouping, lazy pipelines, memoization, copying, numeric utilities | [Collections and iteration](references/collections-iteration.md) | | Paths, text encoding, copying/deleting files, archives, UTC and durations | [Files and time](references/files-time.md) | | JSON/CSV/TOML, Unicode regex, text transformations and diffs | [Serialization and text](references/serialization-text.md) | | Dataclasses/enums, resource lifetimes, logging, environment and child processes | [Records and processes](references/records-processes.md) | | Python AST parsing/transformations, 3.15 constructor changes, source scanners | [AST and source analysis](references/ast-source-analysis.md) | | Runtime migration, removed APIs or missing stdlib modules | [Runtime compatibility](references/runtime-compatibility.md) | Load only the relevant reference. Each is bundled locally; sibling skills are optional. Target **CPython 3.15.2** (stable baseline checked 2026-11-03); recheck Python.org on a future refresh. Older project support is a separate constraint. ## Workflow …

How to install
mdr add lu1sdv/skillsmd/python-stdlib@sha256:c1c43ec408acca07The 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.
