Tests

Review test adequacy for changed code.

Scope

1. Coverage gaps

• new exported functions or modules without tests
• new branches or error paths without coverage
• changed behavior that existing tests do not exercise
• renamed concepts or protocol terms without tests that cover the new form and guard the old form if needed

2. Edge cases

• boundary conditions (empty inputs, missing files, null/undefined)
• error recovery paths (command not found, parse failures)
• configuration variants the code handles
