simplify

name	simplify
description	Read source code and find opportunities to simplify, deduplicate, and consolidate. Apply changes after user approval.

Arguments (optional)

• <scope>: A file path, directory, or free-form description of the range to review (e.g. src/foo.ts, the auth module, lines 100-200 of bar.py).

Steps

1. Resolve the scope:

   • If an argument is provided, use it as the review scope.
   • If no argument is provided:
     • Check the current git branch (git rev-parse --abbrev-ref HEAD).
     • If the current branch is not main (e.g. main, master), use Current branch diff as the review scope.
     • Otherwise, ask the user explicitly which scope to use, using AskUserQuestion with these options:
       • Whole codebase — review all source code in the repository
       • Current branch diff — review changes in the current branch vs the main branch
       • Last commit — review changes in the most recent commit (git show HEAD)
       • Other — let the user specify a custom scope (free-form input)
   • Do NOT proceed until the scope is determined.

2. Review: Read the source code in the resolved scope and identify areas that can be simplified, duplicated parts, and opportunities for refactoring or abstraction.

3. Apply changes after user approval.
