Lint Fix

Target: $ARGUMENTS (if empty, use the whole project root).

Do this mechanically, step by step. Do not ask questions.

1. Detect lint/format tooling by checking the repo root for config/marker files (use ls and Read):

   • JS/TS: package.json (deps/scripts containing eslint and/or prettier), .eslintrc*, eslint.config.*, .prettierrc*, prettier.config.*
   • Python: pyproject.toml or setup.cfg (sections/deps for ruff and/or black)
   • Rust: Cargo.toml (implies cargo fmt / rustfmt)
   • Go: go.mod or any *.go files (implies gofmt) If none of these are found, output exactly: "No lint/format tooling detected." and stop. Make no changes.

2. For each tool detected, run its autofix command, scoped to $ARGUMENTS if given, else the whole project:

   • ESLint: npx eslint --fix $ARGUMENTS (or the project's lint:fix/lint --fix npm script if defined)
   • Prettier: npx prettier --write $ARGUMENTS
   • Ruff: ruff check --fix $ARGUMENTS and ruff format $ARGUMENTS
   • Black: black $ARGUMENTS
   • Rust: cargo fmt
   • Go: gofmt -w $ARGUMENTS (or go fmt ./... if no path given) Run every tool that is actually configured in the project — don't skip any that were detected in step 1.

3. Run git diff --stat to see what changed.

4. Summarize in 3-5 short lines: which tool(s) ran, how many files changed, and the general nature of the changes (e.g. formatting/whitespace, import ordering, quote style). Do not paste the full diff. Do not add extra commentary beyond this summary.
