What version control systems are supported?

The skill intelligently detects the VCS for each repository independently, supporting both standard Git and Jujutsu (jj) workflows.

How does it handle cyclic dependencies?

It uses a version aliasing strategy where the new dependency version is added alongside an aliased version of the old one (e.g., reqwest012). This ensures type compatibility across repo boundaries during the transition period.

Does this skill automatically modify my code?

No, the skill's primary output is a detailed markdown plan. It analyzes your repositories and generates a strategy for human review before any code execution or commits are made.

Why is Cargo.lock insulation important in this workflow?

Because Oxide repositories commit their Cargo.lock, landing an upgrade in one repo won't automatically break others, allowing for a phased and convenient landing order rather than a forced lockstep update.

Can I use this for non-Oxide projects?

Yes. While it follows Oxide's best practices, it is highly effective for any Rust project using workspace dependencies or inter-repo git references.

Developer Tools

Coordinates complex dependency migrations across multiple Rust repositories using version aliasing and cyclic dependency management.

The Cross-Repo Upgrade skill is designed to manage high-stakes dependency updates across interconnected software ecosystems, specifically targeting environments like Oxide's Rust repositories. It solves the challenge of cyclic git dependencies by generating a structured coordination plan that utilizes version aliasing—allowing repositories to land updates independently without breaking downstream consumers. By automating the discovery of inter-repo type boundaries and documenting breaking changes upfront, it transforms risky, manual migrations into a predictable, multi-phase workflow suitable for complex infrastructure projects.
