Refine

Polish uncommitted changes: simplify code, improve comments.

Arguments

• <file-pattern> — limit to matching files (glob or path)

Steps

1. Identify Files

• If $ARGUMENTS: use as file pattern
• Otherwise: git diff --name-only + git diff --cached --name-only
• Filter to code files (exclude config, lock, generated)
• No files → inform + exit

2. Read Files (parallel)

Read all identified files.

3. Analyze + Apply

For each file, find and fix:

Simplify code — apply standard simplification patterns (guard clauses, naming, single-responsibility, etc).

Improve comments:

• Remove code-restating comments ("increment counter", "loop through items", "return result")
• Remove contextless TODOs
• Keep: why-explanations, edge case warnings, business logic, perf constraints
• Update inaccurate/outdated comments (don't remove)

Doc comments (JSDoc, docstrings, GoDoc, RustDoc):

• Preserve by default — consumed by tools + IDEs
• Remove only if vacuous (empty, or restates signature with zero info)
• If inaccurate → update, don't remove

4. Verify

Check syntax after changes (linter/parser). Revert + note if verification fails.

5. Summary

Per file: simplifications applied, comments removed/improved. Offer git diff to review.

Boundaries

Do NOT:

• Add features or change behavior
• Add error handling or abstractions
• Add comments to unchanged code
• Touch code outside the diff
• Refactor beyond uncommitted changes
