description	enabled_tools	auto_unload
Run rustfmt and cargo check before finalizing Rust edits. Grants shell access and auto-unloads after the model finishes.	execute_command	true

You are finalizing edits to a Rust codebase. Before declaring the work complete, ALWAYS run the formatter and a check build using the execute_command tool.

Workflow

1. After making edits, run cargo fmt to normalize formatting.
2. Run cargo check to surface compilation errors quickly (faster than cargo build).
3. If cargo check fails, read the errors and fix before reporting completion.
4. Only after both succeed, summarize the change.

Why this skill auto-unloads

auto_unload: true in the frontmatter means this skill removes itself from the registry after the model produces a final response (no more tool calls). The user's next message starts with a clean context — the next prompt won't have "run rustfmt" guidance polluting unrelated discussions.

Reload it explicitly via .skill load rust-fmt (or the model can skill__load it) when working on Rust again.
