What problem does it solve? Teams lose hard-won insights between sessions: patterns get rediscovered, pitfalls get hit twice, and preferences are forgotten. This Skill maintains a persistent, human-readable knowledge base of project learnings so past discoveries stay searchable and actionable. ## Core Features & Use Cases - Review and Search: Show the 20 most recent learnings or search entries by keyword across keys, insights, sources, and files. - Prune and Validate: Detect stale entries whose referenced files no longer exist and resolve contradictions with user confirmation. - Export and Stats: Format learnings for CLAUDE.md, save a standalone export, or view summary statistics like counts, confidence averages, and top sources. - Use Case: After a debugging session uncovers that CPI calls require PDA signer seeds, record it as a pitfall so the next session recalls it instead of repeating the mistake. ## Quick Start Ask the assistant to show what we have learned on this project so far.
