Plan Lower Code Complexity

Lower Code Complexity

Reduces the CyclomaticComplexity threshold by 2 and fixes all violations.

Step 1: Gather Requirements

1. Read current threshold from .rubocop.yml (Metrics/CyclomaticComplexity Max)
2. Calculate new threshold: current - 2 (e.g., 10 -> 8)
3. Run RuboCop and flog to find violations:

   bundle exec rubocop --only Metrics/CyclomaticComplexity,Metrics/PerceivedComplexity --format json 2>&1
   

   bundle exec flog --all --group app/ 2>&1 | head -50
   

4. Note for each violation:
   • File path and line number
   • Method name
   • Current complexity score (RuboCop and/or flog)

If no violations at new threshold, report success and exit.

Step 2: Compile Brief and Delegate

Compile the gathered information into a structured brief:

Reduce CyclomaticComplexity threshold from [current] to [new].

Methods exceeding threshold (ordered by complexity):
1. [file:method_name] (complexity: X, target: [new]) - Line Y
   - flog score: Z
2. ...

Configuration change: .rubocop.local.yml, Metrics/CyclomaticComplexity Max from [current] to [new]

Refactoring strategies: extract methods, early returns, extract conditions, use lookup hashes, replace conditionals with polymorphism

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