Step-by-Step Workflow

Catalog candidate patterns and expected match fixtures.
Run compatibility checks against required regex flavors.
Debug mismatches with step-level pattern inspection.
Execute ReDoS and backtracking safety checks.
Publish approved patterns with explicit engine notes.

Quality Checks

All fixtures pass in target engines.
No high-risk performance warnings remain.
Pattern documentation includes scope and exclusions.

Common Pitfalls

Assuming JavaScript behavior matches backend engines.
Skipping negative fixtures allows silent false positives.
Ignoring backtracking risk can create production bottlenecks.
