What it does

Uv Workflow is an agent skill from Aedelon/claude-code-blueprint. Master uv package manager for Python: project setup, dependency management, virtual environments, lockfiles, CI/CD integration, Docker builds, and migration from pip/poetry. MUST BE USED when user mentions: "uv", "uv add", "uv run", "uv sync", "uv init", "uv lock", "uv venv", "uv pip", "pyproject.toml", "python project setup", "python dependencies", "virtual environment", "venv", "pip install", "poetry to uv", "migrate from pip", "lockfile python", "requirements.txt", "setup.py", "pip freeze", "uv tool", "install…

Its SKILL.md is about 1.2k 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 Dependency management, Creative writing and fiction and CI/CD. It works with Python, Docker, Rust and npm. The repository describes itself as: Production-grade Claude Code configuration: skills, agents, hooks, rules, and permissions working as a system.

When your agent uses it

  • Python project setup
  • Python dependencies
  • Virtual environment
  • Migrate from pip

Example prompts

  • “uv add”
  • “uv run”
  • “uv sync”
  • “/uv-workflow”

Requirements

  • Python 3
  • Docker
  • Pre-approved tools (allowed-tools): Bash, Read, Write, Edit, Grep, Glob, mcp__context7__resolve-library-id, mcp__context7__get-library-docs

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

  1. Always use uv run instead of activating venv
  2. Commit uv.lock to git
  3. Use --frozen in CI for reproducible builds
  4. Pin Python version with .python-version
  5. Separate dev deps from production deps
  6. Use workspaces for monorepos
  7. Export requirements.txt for compatibility when needed

What it can do on your machine

Read from SKILL.md and the folder at commit 3bb5099. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Bash
    • Read
    • Write
    • Edit
    • Grep
    • Glob
    • mcp__context7__resolve-library-id
    • mcp__context7__get-library-docs

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • uv

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

  • Network

    No URLs in SKILL.md. Its commands use uv, 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 Workflow loads about 1.2k tokens when it runs. Until then it costs about 213 tokens; SKILL.md has 165 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~213
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

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: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
    allowed-tools: Bash, Read, Write, Edit, Grep, Glob, mcp__context7__resolve-library-id, mcp__context7__get-library-d

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

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 165 words (~1,229 tokens).

“Ultra-fast Python package installer and resolver written in Rust. 10-100x faster than pip.”
