Bug Hunter

When to use this skill

• •Use when an uncaught exception or runtime error appears in the dev console or during test runs.
• •Triggered by pasting stack traces or describing symptoms such as undefined is not a function.

Instructions

1. •

   First Step: Parse the supplied stack trace, map frames to repository files and commit contexts, and verify file paths exist in src/.

2. •

   Second Step: Open the suspected file and locate the referenced line; inspect common causes (null/undefined deref, incorrect prop shape, async timing issues).

3. •

   Third Step: Suggest a minimal repro or test and provide a small patch or code comment describing the likely fix.

Examples

• •Given: TypeError: Cannot read property 'map' of undefined at PaperFeed.tsx:42 -> check papers prop initialization and defensive checks.

Notes

• •Recommend adding guard clauses and unit tests reproducing the failure; avoid speculative fixes without repro.
