description	This skill should be used when fixing all violations of one or more RuboCop cops across the codebase. It runs RuboCop, groups violations by cop and file, generates a brief with fix strategies, and creates a plan with tasks to implement the fixes.

Fix Linter Errors

Target cops: $ARGUMENTS

If no arguments provided, prompt the user for at least one RuboCop cop name.

Step 1: Gather Requirements

1. Parse cops from $ARGUMENTS (space-separated)
2. Run RuboCop to collect all violations:

   bundle exec rubocop --format json 2>&1
   

3. Group violations by cop, then by file, noting:
   • File path and line numbers
   • Violation count per file
   • Sample offense messages

Step 2: Compile Brief and Delegate

Compile the gathered information into a structured brief:

Fix RuboCop violations for cops: $ARGUMENTS

Violations by cop:
- [CopName1]: X total violations across Y files
  - [file]: N violations (lines: ...)
  - ...
- [CopName2]: X total violations across Y files
  - ...

Fix strategies: extract methods, reduce complexity, apply auto-correct where safe

Verification: `bundle exec rubocop --format simple 2>&1 | grep -E "($ARGUMENTS)" | wc -l` -> Expected: 0
