vendor-local

Vendor local Rust crates by copying them into Firefox's third_party/rust directory and updating Cargo.toml and Cargo.lock references. The vendor-local Skill automates this process, supporting single and multi-commit vendoring with optional fork or path dependency strategies for testing local changes before upstream integration.

Yes. Vendoring local crates into Firefox's third_party/rust directory lets you test changes immediately. The Skill handles repository path discovery, branch or commit selection, cargo updates, and optional try testing workflows.

Fork strategy pushes your local crate to a forked repository before vendoring; path dependency strategy references the local path directly in Cargo.toml. Choose based on whether you need a remote reference or prefer local-only testing during development.

The Skill automates Cargo.lock updates as part of the vendoring process. You specify the branch or commit to vendor, and dependency references are updated accordingly without manual Cargo.lock edits.

You need the local repository path, Cargo.toml and Cargo.lock accessible in Firefox's tree, knowledge of which branch or commit to vendor, and Cargo installed. The Skill guides repository discovery and branch selection through scripted prompts.

Yes. The Skill supports both single-commit and multi-commit vendoring workflows, allowing you to integrate multiple related changes from your local repository into Firefox's vendored Rust tree with coordinated dependency updates.
