plan-improve-tests

This skill should be used when improving test quality. It scans the test suite for weak, brittle, or poorly-written tests, generates a brief with improvement opportunities, and creates a plan with tasks to strengthen the tests.

Improve Test Quality

Target: $ARGUMENTS

If no argument provided, scan the full test suite.

Step 1: Gather Requirements

Run test suite to establish baseline:

bun run test 2>&1 | tail -20

Scan test files for quality issues:

Weak assertions (toBeTruthy, toBeDefined instead of specific values)
Missing edge cases (no boundary values, no error paths)
Implementation coupling (testing internals rather than behavior)
Missing error path coverage
Duplicated setup that could indicate missing abstractions

Identify 10-20 test files with highest improvement potential, noting:

File path
Issues found (weak assertions, missing edge cases, etc.)
Estimated impact of improvement

Step 2: Compile Brief and Delegate

Compile the gathered information into a structured brief:

Improve test quality across the test suite. Test files needing improvement (ordered by impact): 1. [test file] - [issues found] - Weak assertions: [count] - Missing edge cases: [description] - Implementation coupling: [description] 2. ... Verification: `bun run test` -> Expected: All tests pass, improved assertions and coverage

Invoke /plan-execute with this brief to create the implementation plan.
