What problem does it solve? Valuable lessons learned during an agent session — corrections, validated approaches, user preferences, and project decisions — are lost when the session ends, forcing the next session to relearn them. This Skill captures those durable lessons and persists them to agent memory or the project's committed convention file so future sessions start better-informed. ## Core Features & Use Cases - Signal Detection: Scans the conversation for four lesson types: corrections, quietly accepted non-obvious choices, revealed working preferences, and project decisions not in version control. - Ruthless Filtering: Drops anything derivable from code, standard best practices, one-off details, or lessons already recorded — persisting nothing is a valid outcome. - Typed Destinations: Classifies each lesson as user, feedback, project, or reference (routed to agent memory) or as a codebase convention (routed to the committed convention file like AGENTS.md or CLAUDE.md). - Interactive Approval: Proposes each candidate one at a time with a draft entry and blocks on user approval before writing anything. - Use Case: At the end of a working session where the user corrected your commit message style twice and revealed a stakeholder deadline, run the skill to save those lessons to project memory so the next session applies them automatically. ## Quick Start Ask the agent to reflect on this session and save the lessons worth remembering.
