python-matrix SKILL.md skillB
python-matrix from gems-uff/noworkflow is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Runs the suite on every Python version of the CI matrix — locally with uv, on Linux x86_64 in the reference container, on the CI legs and on the macOS and Windows legs of the pre-release matrix — checks that the collector still handles a construct on each version, triages a failure that shows on one leg only, and keeps the matrix in step with python.org (the experimental leg of the next version, its promotion with the move of the reference leg and its goldens, the removal of the version that…
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
# The suite on every supported Python `.venv` runs one Python, the reference leg's. Users run noWorkflow inside their own interpreter, anywhere in the supported range, and between two versions more changes than the version string: - **The AST.** Each version adds nodes, and the collector rewrites the AST of the traced script (`prov_definition/`, `prov_execution/`) through `pyposast`. A construct that neither the syntax corpus of the e2e tests nor the examples use is covered on no version (`AGENTS.md`, "Blind spots of the suite"). - **The standard library.** On Windows, `ntpath.isabs` stopped taking a rooted path without a drive as absolute; from 3.15, UTF-8 mode is on by default (PEP 686), so an `open()` without `encoding=` reads differently at the two ends of the range. - **The dependencies.** `uv.lock` resolves separately per Python fork (the `resolution-markers` at its top), so a package may be locked at two versions on two legs (`dependencies`), and a new interpreter may find no wheel for a package and build it from source. - **The interpreter build.** Two builds of the same version can differ in …

How to install
mdr add gems-uff/noworkflow/python-matrix@sha256:dbb6ead503845187The line at the top of this page pins the label git:20261021.ab3d214, 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.
