Quick Review

This skill provides comprehensive webhook implementation guidance with proper security patterns including signature verification, replay protection, and idempotency handling. The description clearly indicates when to use it, and the task knowledge is strong with complete TypeScript code examples for Express.js endpoints, signature validation, and event handling patterns. Structure is logical with clear sections and a helpful error table. However, novelty is limited since webhook signature verification is a well-documented pattern that a CLI agent could implement with standard library lookups, and the skill doesn't address complex edge cases or Instantly-specific nuances beyond generic webhook patterns. The code examples are production-ready but follow common industry practices rather than solving particularly challenging problems.
