python plugins

pytest — Python testing framework and idioms beyond unittest. Use when writing, running, or configuring pytest tests — plain `assert` (rewritten), DI `@pytest.fixture` (scopes/autouse/yield/conftest), `@pytest.mark.parametrize`, `skip`/`skipif`/`xfail` + markers, `raises`/`warns`/`approx`, fixtures (`tmp_path`/`monkeypatch`/`capsys`/`caplog`), the CLI (`-k`/`-m`/`-x`/`--lf`/`--pdb`), config (`pyproject.toml`/`pytest.ini`). Includes `(pytest N.M+)` annotations. Not unittest, tox, or coverage.

by Alberto Leal

Measure Python complexity per function and per call path with ruff and complexipy; optionally add Jev judgments through configurable providers (Vercel by default). Use when prioritizing refactors, investigating over-layering, or verifying that a refactor improved the whole path. Without the selected provider key, semantic review is skipped and static analysis continues. Tests verify behavior.

ruff — Astral's one fast (Rust) binary that is both a Python linter (`ruff check`) and a Black-compatible formatter (`ruff format`). Use when linting or formatting Python, configuring `[tool.ruff]`/`ruff.toml`, choosing rules with `select`/`extend-select`/`ignore`, looking up codes like F401/E501/B008, applying fixes (`--fix`, `--unsafe-fixes`), suppressing (`# noqa`, `# ruff: ignore[...]`), or enabling preview rules. Includes `(ruff 0.X+)` + preview annotations. Not uv or ty.

Shrink a test suite without losing an asserted fact or a covered branch: a fact matrix of what each test pins plus per-test branch coverage and a verified covering set, deleting only on the intersection, with a mutant check for every relocated fact. Use when asked to trim, dedupe, consolidate, or reduce tests or test SLOC, when a suite grew by accretion, when deciding whether to delete, fold, or parametrize tests, or before cutting a test on 'coverage is unchanged' alone. Python/pytest.

ty — Astral's extremely fast (Rust) Python type checker and language server, in 0.0.x beta. Use when running or configuring `ty check`, reading ty diagnostics, setting rule levels in `[tool.ty]`/`ty.toml`, writing `# ty: ignore[rule]` suppressions, debugging environment or module-resolution failures, wiring ty into CI (exit codes, `--output-format github`), or migrating from mypy/pyright. Pinned to ty 0.0.72. The type checker — NOT ruff (lint/format) or uv (packaging).

by Alberto Leal

uv — Astral's fast Python package & project manager, one binary replacing pip/pipx/pyenv/poetry/virtualenv. Use when managing Python projects with pyproject.toml + uv.lock (uv init/add/sync/lock/run), running PEP 723 inline-dependency scripts, running one-off tools with uvx, installing/pinning Python versions (uv python), migrating from pip (uv pip), building/publishing packages, or configuring indexes/resolution/cache. Includes `(uv 0.X+)` version annotations. The uv CLI, not ruff/ty.

Build generative UI with OpenUI — any LLM provider, any backend language. Scaffold, integrate, validate.

by Fused

Skills for using and authoring fused-render: running the local explorer and opening views, authoring HTML pages with a fused.runPython() bridge to local Python, URL-synced params, file IO helpers, custom preview templates, the machine-wide file index, the AI API (fused.ai text/streaming, local models, image generation), and background apps (a folder's own supervised long-running daemon).

by babs

Daily-driver toolkit: spec-driven feature flow (spec → ship → review → commit), project init standards (FastAPI+PostgreSQL+React full-stack, Python, Go, Dockerfile), review workflows (iterative, swarm, full-project), conventional-commit flow, sharing utilities, and an optional quota-aware status line.
