bidirectional-differential

bidirectional-differential is a Plan & work review gates skill for AI agents, published by jszmajda in the lid repository on GitHub. Skillspace rates bidirectional-differential C (74/100) and it passed the safety scan; the rating is based on static analysis only.

Audit coherence across an arrow of intent by running two parallel fresh Claude sessions — one reconstructs code from a single EARS, the other reconstructs the EARS from stripped code — then classifies the drift between them. Use when the user invokes /differential-audit, asks to audit EARS-to-code drift for a feature or segment, wants a differential round-trip on a specific spec, or reaches Phase 6 code-complete in linked-intent-dev with arrow-maintenance overlay present and a touched-EARS set to consider. Surfaces intent that the code encodes but the EARS doesn't state, and requirements the EARS states but the code under-pins. Requires docs/arrows/ overlay. Heavy per-EARS cost in subprocess spawns and Anthropic API spend; scope via the opening conversation before running.
