Lisa Improve Test Coverage

Increase Test Coverage

Target threshold: $ARGUMENTS%

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

Step 1: Gather Requirements

1. Find coverage config (jest.config.js, vitest.config.ts, .nycrc, etc.)
2. Run coverage report to get current state:

   status=0
   bun run test:cov >coverage.log 2>&1 || status=$?
   head -n 100 coverage.log; echo "exit=$status"
   

   The status is captured before the pipe, because a pipeline reports its LAST stage's exit code — head always succeeds, so a failing run reads as exit=0 (falsifiable-checks, pager-shadowed status). || status=$? rather than ; status=$?: under set -e the ; form exits before the assignment, so the failure is never reported at all.
3. Identify the 20 files with lowest coverage, noting:
   • File path
   • Current coverage % (lines, branches, functions)
   • 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: [config file path], update thresholds to $ARGUMENTS%

Verification: `bun run test:cov` → Expected: All thresholds pass at $ARGUMENTS%
