Python uv Scripting FAQs

Question 1

What is PEP 723 and how does this skill use it?

Accepted Answer

PEP 723 defines a standard for embedding dependency metadata directly within a Python script. This skill helps you correctly format this metadata so that tools like uv can automatically manage the environment and dependencies for that specific file.

Question 2

How does this skill handle script security?

Accepted Answer

The skill provides patterns for secure secrets management using environment variables, keyrings, or tools like Infisical, alongside best practices for input validation and secure command execution.

Question 3

Can I use this skill to automate CI/CD workflows?

Accepted Answer

Yes, it includes specific integration patterns for GitHub Actions and GitLab CI, showing how to use the uv setup actions to run your scripts reliably in automated pipelines.

Question 4

Why shouldn't I use [tool.uv.metadata] in my scripts?

Accepted Answer

[tool.uv.metadata] is an invalid pattern that causes TOML parsing errors in uv. This skill enforces the correct use of valid PEP 723 fields and suggests using Python docstrings for custom script documentation instead.

Question 5

When should I use a single-file script versus a full uv project?

Accepted Answer

Use single-file scripts for utilities under 500 lines that don't require shared modules. For complex applications with multiple files, database models, or 15+ dependencies, the skill recommends transitioning to a standard uv project structure.
