name	plan-reduce-max-lines
description	This skill should be used when reducing the maximum class/module lines threshold and fixing all violations. It updates the RuboCop configuration, identifies classes and modules exceeding the new limit, generates a brief with refactoring strategies, and creates a plan with tasks to split oversized files.

Reduce Max Lines

Target threshold: $ARGUMENTS lines per class/module

If no argument provided, prompt the user for a target.

Step 1: Gather Requirements

1. Read current config from .rubocop.yml or .rubocop.local.yml (Metrics/ClassLength and Metrics/ModuleLength)
2. Run RuboCop with the target threshold to find violations:

   bundle exec rubocop --only Metrics/ClassLength,Metrics/ModuleLength --format json 2>&1
   

3. Note for each violation:
   • File path
   • Class/module name
   • Current line count

If no violations at $ARGUMENTS, report success and exit.

Step 2: Compile Brief and Delegate

Compile the gathered information into a structured brief:

Reduce max class/module lines threshold to $ARGUMENTS.

Classes/modules exceeding threshold (ordered by line count):
1. [file:ClassName] - [current] lines (target: $ARGUMENTS)
2. ...

Configuration change: .rubocop.local.yml, Metrics/ClassLength Max to $ARGUMENTS, Metrics/ModuleLength Max to $ARGUMENTS

Refactoring strategies: extract concerns, extract service objects, remove duplication, delete dead code, simplify logic

Verification: `bundle exec rubocop --only Metrics/ClassLength,Metrics/ModuleLength --format simple 2>&1 | grep "offense" | wc -l` -> Expected: 0
