How does uv handle reproducible builds?

uv uses a lockfile (uv.lock) to ensure that every environment uses the exact same versions of dependencies, which can be enforced using the --frozen flag during sync.

Does this skill help with migrating from Poetry?

Yes, it provides patterns for using existing pyproject.toml files and migrating dependencies from Poetry, pip-tools, or requirements.txt into the uv ecosystem.

Can I use uv to manage different Python versions?

Yes, uv includes built-in Python management capabilities, allowing you to install, list, and pin specific Python versions for your projects without external tools.

How much faster is uv compared to traditional tools like pip?

uv is typically 10-100x faster than pip because it is written in Rust and utilizes an advanced dependency resolver and a global cache.
