modern-python-toolchain

Modern Python project setup with uv, ruff, and pyright. Use when initializing a new Python project, configuring the Python environment, setting up linting/formatting, or when a project needs uv (the fast Python package manager). Trigger on: 'set up Python', 'new Python project', 'configure uv', 'install uv', 'ruff', 'pyright', 'Python linting', 'Python formatting', or when a task requires Python and no pyproject.toml exists yet.

Quality

Content

85%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is a high-quality, actionable toolchain guide with executable commands, clear sections, and well-signaled external doc references for depth. Its main weakness is conciseness: time-sensitive version pins and minor editorial fluff are not isolated in a deprecated section.

Suggestions

Move or isolate time-sensitive version statements ('Python 3.14 is the latest stable', the uv_build '0.11.28' bound) into an 'old patterns' or 'current versions' section so they don't penalize the lean core, or strip the concrete version numbers and say 'the version bound tracks your installed uv'.

Remove marketing-fluff descriptors like 'extremely fast' (used for both uv and ruff) — assume Claude knows the tools' reputation.

Consider splitting the 'Coding style' section (pydantic v2, typer CLI) into a separate reference file if the toolchain guide grows, keeping SKILL.md a pure setup/lint/type-check overview.

Dimension	Reasoning	Score
Conciseness	Mostly lean (terse rules, tight command reference, copy-paste snippets), but time-sensitive version info — 'Python 3.14 is the latest stable' and 'uv_build>=0.11.28,<0.12.0' with comment 'here: 0.11.28' — is not placed in a deprecated/old-patterns section, and 'extremely fast' editorial fluff appears twice. Not 3 because the guideline penalizes time-sensitive version numbers outside a deprecated section; not 1 because the bulk assumes Claude's competence and earns its tokens.	2 / 3
Actionability	Fully executable, copy-paste-ready guidance throughout: install commands ('curl -LsSf https://astral.sh/uv/install.sh \| sh'), 'uv add --dev', pyproject.toml/ruff config snippets, and runnable Python examples. Not 2 because there is no pseudocode or missing key details.	3 / 3
Workflow Clarity	Clear sequenced flows such as the post-edit 'ruff check --fix' then 'ruff format' workflow, with '--diff' as an explicit preview checkpoint. Not 2 because no destructive/batch operations are present that would require a validate-fix-retry loop to cap the score, and the sequences are explicit.	3 / 3
Progressive Disclosure	Well-organized section headers (Installing uv, uv basics, ruff, pyright, Coding style) with clearly signaled one-level-deep external references ('For detailed information: https://docs.astral.sh/uv/'). No bundle files exist, and the inline getting-started content is appropriately cohesive; not 2 because references are clearly signaled and navigation is easy.	3 / 3
	Total	11 / 12 Passed

Description

100%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is excellent: third-person voice, concrete actions, explicit 'Use when'/'Trigger on' guidance, and a broad set of natural trigger phrases. It clearly distinguishes the modern uv/ruff/pyright toolchain from generic Python skills.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete actions — 'initializing a new Python project, configuring the Python environment, setting up linting/formatting' — matching the anchor for several specific actions rather than a single domain mention (2).	3 / 3
Completeness	Explicitly answers both what ('Modern Python project setup with uv, ruff, and pyright') and when ('Use when...', 'Trigger on:...'). Not 2 because the 'when' is explicit, not merely implied.	3 / 3
Trigger Term Quality	Broad set of natural trigger phrases users would actually say: 'set up Python', 'new Python project', 'configure uv', 'install uv', 'ruff', 'pyright', 'Python linting', 'Python formatting'. Not score 2 because coverage spans many common variations, not just a few.	3 / 3
Distinctiveness Conflict Risk	Clear niche around the uv/ruff/pyright modern toolchain with distinct triggers ('configure uv', 'no pyproject.toml exists yet'), unlikely to fire for the wrong skill. Not 2 because the named tools and triggers are specific rather than a generic 'works with Python files'.	3 / 3
	Total	12 / 12 Passed
