bugfix-and-debug

Debugging failing tests involves collecting evidence from error messages and stack traces, forming hypotheses about root causes, applying minimal fixes, and verifying with composer test and npm run tests. This Skill guides you through structured diagnosis across both Laravel backend and React frontend environments.

Diagnose errors by running mandatory verification commands (composer test, npm run types, npm run lint), examining stack traces to identify failure points, hypothesizing root causes, and applying targeted fixes. The Skill provides structured templates to document findings and validate fixes.

Fix bugs by following a verification loop: collect evidence, form hypotheses, apply a minimal fix, then run regression tests. This Skill emphasizes verification templates and structured bugfix reports to confirm your fix doesn't break existing functionality.

Yes. This Skill applies to failing Pest tests in Laravel and Vitest tests in React, handling exceptions, TypeErrors, and unexpected behavior across both test frameworks.

After applying a fix, verify it by running composer test, npm run types, and npm run lint, then output a structured bugfix report documenting the issue, root cause, fix applied, and verification results.
