effect-anti-pattern-review

Identify React useEffect anti-patterns in a PR diff by applying a grep-driven checklist that maps modified useEffect, setInterval, setTimeout, or fetch calls to known anti-patterns and ties each hit to a concrete fix.

Common React useEffect anti-patterns include missing or incorrect dependency arrays, absent cleanup functions for intervals and timeouts, and improperly handled fetch calls, all enforced through a deterministic grep checklist.

Yes, this useEffect review works for both metamask-extension and metamask-mobile, enforcing proper dependencies and cleanup best practices across both React codebases during PR changes.

Enforce proper useEffect cleanup and dependencies before merging by running a grep-driven audit on PR changes that detects anti-patterns and provides actionable guidance with suggested fixes.

The best way to automate React useEffect code review is using a grep-driven checklist that scans PR diffs for anti-patterns in effects, intervals, and fetch calls, then ties hits to documented deterministic fixes.
