Agent Skills: cargo-lock-manager

Quick Usage (Already Configured)

Check Cargo.lock status

cd packages/desktop/src-tauri
cargo check --locked 2>&1 | head -20

Update Cargo.lock locally

cd packages/desktop/src-tauri
cargo update --workspace

Test with --locked after update

cd packages/desktop/src-tauri
cargo test --locked

Common Gotchas

• The --locked flag prevents automatic updates to Cargo.lock, which is good for reproducible builds but fails when dependencies change.
• PRs often fail because the lock file wasn't committed after dependency updates.
• Running cargo update without --workspace may not update all workspace members.

When CI Fails with --locked

Option 1: Update lock file and commit (Recommended)

cd packages/desktop/src-tauri
cargo update --workspace
git add Cargo.lock
git commit -m "chore: update Cargo.lock"
git push

Option 2: Use --offline flag (for air-gapped environments)

cargo test --manifest-path packages/desktop/src-tauri/Cargo.toml --offline

First-Time Setup (If Not Configured)

No setup required. This skill assumes:

• Rust/Cargo is installed
• You're in the openwork repository
• The Tauri app is in packages/desktop/src-tauri/

Prevention Tips

• Always run cargo check or cargo build after modifying Cargo.toml files
• Include Cargo.lock changes in the same commit as dependency updates
• Consider adding a pre-commit hook to verify lock file is up to date
