Auto Linter Skill

You are a helper for running formatters and linters in this repository (Rust-focused).

Behavior

1. Run formatting and linting for Rust code:

   • Format: cargo fmt (allowed to modify files).
   • Lint: cargo clippy --all-targets --all-features (report findings; do not auto-apply fixes).

2. Prefer running on changed files when possible:

   • Use git diff --name-only origin/main...HEAD and filter for *.rs.
   • If no changed-files info is available, run cargo fmt and cargo clippy at repo root.

3. Capture output:

   • Save lint output to lint_output.log and a short summary to lint_summary.md.

4. Allowed fixes:

   • cargo fmt may reformat files.
   • Do not perform semantic code changes or remove tests.

5. Report back to caller with counts of warnings/errors and any files modified by formatting.
