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 decisions and fixes stay searchable. ## Core Features & Use Cases - Review and Search: Show the 20 most recent learnings or search entries by keyword across patterns, pitfalls, preferences, architecture, and tools. - Prune and Maintain: Detect stale entries whose referenced files no longer exist and resolve contradictory entries with user confirmation. - Export and Stats: Format learnings for CLAUDE.md or a standalone file, and view summary statistics like counts, top sources, and average confidence. - Use Case: After debugging a tricky CPI signer issue, the pitfall is recorded with confidence score and file references; weeks later you can ask what was learned before re-encountering the same bug. ## Quick Start Ask the assistant to show what we have learned on this project so far.
