Coding Prompts

Debugging, review, refactoring, and the parts of the job that are mostly reading code. 18 prompts in this category.

• Bug Root-Cause IsolationUse when you have a reproducible error and want the cause named before anyone starts editing.
• Code Review for Silent FailuresRun this on any diff touching async code or external calls before you approve it.
• Refactor Without Behavior ChangeFor cleanup work on code with weak test coverage, where an accidental behavior change would go unnoticed.
• Test Case Generation from SpecBest right after writing a function, while the intended contract is still fresh.
• Legacy Code ComprehensionFirst thing to run when you inherit a service nobody remembers writing.
• API Contract DiffingBefore shipping any schema change to an endpoint with external consumers.
• Performance Bottleneck TriageWhen something is slow and you want one hypothesis to test rather than five guesses.
• Dependency Upgrade Risk CheckFor major-version bumps where the changelog is long and mostly irrelevant to you.
• SQL Query ExplainerFor inherited queries with nested subqueries, or when you suspect a missing index.
• Commit Message from DiffFor commits where the reasoning will not be obvious to whoever runs git blame in a year.
• Regex Builder and ExplainerWhen you need a regex you can actually defend in code review.
• Error Message Clarity ReviewFor improving UX and reducing support tickets from cryptic errors.
• Type Safety HardeningBefore removing a ts-ignore or shipping a new endpoint.
• Dead Code DetectorBefore a cleanup PR, to avoid deleting something loaded dynamically.
• Accessibility Lint for MarkupRun before shipping any user-facing form or interactive component.
• Function Decomposition PlannerWhen a function is too long to test and too tangled to review.
• Migration Script GeneratorFor schema changes on tables with production data.
• Pull Request Description WriterFor PRs where reviewers need context the diff alone will not give them.
