What happens if a dependency update causes a compilation error?

The workflow includes a verification step that runs 'mix compile --warnings-as-errors'. If errors occur, the skill attempts to resolve them or allows for a revert of that specific dependency.

Does this skill support non-Elixir package managers like npm or Cargo?

No, this skill is specifically optimized for Elixir projects using the Mix build tool and Hex package manager.

Does it modify my mix.lock file automatically?

Yes, it uses standard Mix commands to update the lockfile and ensures that changes to both mix.exs and mix.lock are synchronized.

How does it handle breaking changes in major updates?

The skill researches official Hexdocs, repository changelogs, and release notes to identify required code or configuration changes before applying major version bumps.

Can I use this with Elixir umbrella projects?

Yes, it is designed to recognize umbrella structures and can update version constraints across multiple apps within the umbrella root.

Developer Tools

Automates the upgrading of Elixir Mix and Hex dependencies with smart versioning, changelog research, and verification.

The Update Elixir Dependencies skill provides a comprehensive workflow for maintaining Elixir projects by systematically managing Mix and Hex package upgrades. It intelligently distinguishes between safe patch/minor updates and potentially breaking major versions, performing automated research into changelogs and migration guides for the latter. By enforcing post-update verification through compilation checks, formatting, and test suite execution, it ensures that dependency bumps never compromise project stability or code quality.
