What problem does it solve? Repeated mistakes across sessions waste time and erode trust. This Skill captures corrections and hard-won rules as durable lessons with confidence scores, so the same guidance resurfaces automatically before similar future work instead of being forgotten. ## Core Features & Use Cases - Confidence-Weighted Lessons: Each saved rule carries a confidence score that strengthens when the same content is saved again and decays when unused, separating repeated corrections from one-off noise. - Context-Triggered Recall: Lessons are scoped to a trigger situation and optionally to a project, so memory_lesson_recall surfaces the right rule before work of the same type begins. - Use Case: After a CI pipeline hangs because bare vitest entered watch mode, save the rule "Run vitest with --run in CI contexts" so every future session touching CI scripts recalls it before running tests. ## Quick Start Ask the assistant to learn a rule from your correction, for example: "Learn this: always run vitest with --run in CI or the pipeline hangs."
