Increase Test Coverage

Target threshold: $ARGUMENTS%

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

Step 1: Gather Requirements

1. Find coverage config (.simplecov or spec/spec_helper.rb)
2. Run test suite with coverage to get current state:

   bundle exec rspec 2>&1 | tail -50
   

3. Check SimpleCov output in coverage/index.html or console output
4. Identify the 20 files with lowest coverage, noting:
   • File path
   • Current coverage % (lines, branches)
   • Which lines/branches are uncovered

Step 2: Compile Brief and Delegate

Compile the gathered information into a structured brief:

Increase test coverage from [current]% to $ARGUMENTS%.

Files needing coverage (ordered by coverage gap):
1. [file] - [current]% coverage (target: $ARGUMENTS%)
   - Uncovered: [lines]
   - Missing branch coverage: [lines]
2. ...

Configuration: .simplecov, update minimum_coverage to $ARGUMENTS%

Verification: `bundle exec rspec` -> Expected: SimpleCov reports >= $ARGUMENTS% coverage
