uv workflows for Python — dependencies, virtualenvs, PEP 723 scripts, Python version management, CI, and Docker.

  • Working on Python packaging/deps/tooling
  • SKILL.md covers Daily workflows, Performance knobs, CI: GitHub Actions and Docker (multistage — the one…, plus 2 more sections
  • Calls uv, python and uvx
  • Writing GitHub Actions for Python projects

What it does

Uv is an agent skill from harperreed/dotfiles. uv workflows for Python — dependencies, virtualenvs, PEP 723 scripts, Python version management, CI, and Docker. Use when working on Python packaging/deps/tooling, writing GitHub Actions for Python projects, or building Docker images for Python apps.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in DevOps & Cloud, covering CI/CD and Containers. It works with Python, Docker and GitHub Actions. The repository describes itself as: Dotfiles. Managed by YADM.

When your agent uses it

  • Working on Python packaging/deps/tooling
  • Writing GitHub Actions for Python projects
  • Building Docker images for Python apps

Example prompts

  • “/uv”

Requirements

  • Python 3
  • Docker

What it can do on your machine

Read from SKILL.md and the folder at commit b78c10e. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • uv
    • python
    • uvx
    • pip
    • pipx
    • poetry
    • pyenv

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use uv, uvx, pip and pipx, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Uv loads about 1.1k tokens when it runs. Until then it costs about 63 tokens; SKILL.md has 187 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~63
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 187 words (~1,134 tokens).

“Assumption: uv is installed and on PATH (uv --version to confirm; if missing, halt and report). Version pins below were current 2026-07-05 — verify before relying on them.”
