What problem does it solve? When capturing lessons learned into a persistent memory system, teams risk storing duplicate entries, missing contradictions with prior knowledge, or bloating the knowledge base with redundant items. This Skill compares each extracted lesson against existing memory so only genuinely new knowledge gets stored. ## Core Features & Use Cases - Lesson Classification: Labels each lesson as New, Duplicate, Reinforcement, or Contradiction by searching existing memory with the ca search command. - Deduplication Gate: Recommends storing only New lessons and flags Contradictions for human review before they corrupt the knowledge base. - Team Collaboration: Operates as an AgentTeam member in the compound phase, sharing classifications with the solution-writer agent via direct messages. - Use Case: After a debugging session yields five candidate lessons, run this Skill to discover that two are already captured, one reinforces an existing item, one contradicts a prior assumption, and only one is truly new and worth storing. ## Quick Start Compare these extracted lessons against existing memory and classify each one as New, Duplicate, Reinforcement, or Contradiction with a store or skip recommendation.
