Install

Skills CLI

npx skills add simonw/skills

Asks which skills and agents to install. Just one: npx skills add simonw/skills --skill cogapp-markdown — add -g for every project.

Claude Code

git clone https://github.com/simonw/skillscp -r "skills/cogapp-markdown" ~/.claude/skills/

Copies the cogapp-markdown skill into ~/.claude/skills/ for every project (use .claude/skills/ for one project). Repeat for the other skills listed below.

Plugin

/plugin marketplace add simonw/skills

Run inside Claude Code if the repository ships a plugin marketplace, then pick plugins from /plugin.

Skills can run code on your machine — read the SKILL.md first.

What it does

In the author's own words, from each skill's SKILL.md.

  • cogapp-markdown

    Use cogapp to auto-generate sections of markdown documentation by embedding Python code that produces content. Use when a project needs to keep documentation in sync with code, such as embedding CLI --help output in README files, generating tables, or any content that should be derived from the code itself rather than manually maintained.

  • setup-to-pyproject

    Migrate Python projects from setup.py/setup.cfg to pyproject.toml for use with uv. Use when upgrading legacy Python packaging, converting setup.py to modern pyproject.toml format, setting up dependency groups for development/testing, and ensuring `uv run pytest` works correctly.

  • upgrade-actions

    Upgrade GitHub Actions workflows

    upgrade-actions/SKILL.md on GitHub (opens in a new tab)

  • uv-tdd

    A development process for Python applications that uses TDD to iterate on a new project based around uv. Use when Claude needs to create a new Python project, write Python code with tests, or work on Python development using test-driven development practices with the uv package manager.

Review before you install

A skill is a set of instructions and scripts your agent will follow, and it can run code on your machine. Read the SKILL.md and any scripts first — this listing is not a security review.
