Guides bug report and pull request investigation and reproduction. Confirms reported behavior is wrong, reproduces issues locally, and checks for correct-by-design behavior before writing fixes. Use when given a bug report, issue, or error report to investigate.
When given a bug report or a link to issue or pull request, first confirm current behavior is actually wrong
Reproduce, then check if the reported behavior is correct-by-design before writing any fix
Find repositories/CodeSandbox/StackBlitz source files and local fixtures to actually reproduce the issue at hand
To fetch stackblitz.com reproduction url: pnpx stackblitz-zip https://stackblitz.com/edit/{name} {filename}.zip
If no reproduction provided, create a minimal one from the report
Trace the full code path end-to-end for full context and consider options — don't blindly apply a local fix
Look up relevant fixtures and tests to better understand scope and context
Check git blame/git log around the affected area for recent changes
