+# Fix Review
+
+## Overview
+
+Verify that fix commits properly address audit findings without introducing new bugs or security vulnerabilities.
+
+## When to Use This Skill
+
+Use this skill when you need to verify fix commits address audit findings without new bugs.
+
+Use this skill when:
+- Reviewing commits that address security audit findings
+- Verifying that fixes don't introduce new vulnerabilities
+- Ensuring code changes properly resolve identified issues
+- Validating that remediation efforts are complete and correct
+
+## Instructions
+
+This skill helps verify that fix commits properly address audit findings:
+
+1. **Review Fix Commits**: Analyze commits that claim to fix audit findings
+2. **Verify Resolution**: Ensure the original issue is properly addressed
+3. **Check for Regressions**: Verify no new bugs or vulnerabilities are introduced
+4. **Validate Completeness**: Ensure all aspects of the finding are resolved
+
+## Review Process
+
+When reviewing fix commits:
+
+1. Compare the fix against the original audit finding
+2. Verify the fix addresses the root cause, not just symptoms
+3. Check for potential side effects or new issues
+4. Validate that tests cover the fixed scenario
+5. Ensure no similar vulnerabilities exist elsewhere
+
+## Best Practices
+
+- Review fixes in context of the full codebase
+- Verify test coverage for the fixed issue
+- Check for similar patterns that might need fixing
+- Ensure fixes follow security best practices
+- Document the resolution approach
