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 at .superstack/learnings.md so patterns, pitfalls, preferences, architecture decisions, and tool choices survive across sessions. ## Core Features & Use Cases - Review and search learnings: Show the 20 most recent entries or search by keyword across keys, insights, sources, and files. - Prune and maintain quality: Detect stale entries whose referenced files no longer exist and contradictory entries, then remove, keep, or update them with user confirmation. - Export and statistics: Format learnings for CLAUDE.md or a standalone file, and view summary stats like entry counts, top source skill, and average confidence. - Use Case: After a debugging session uncovers that CPI calls require PDA signer seeds, the pitfall is recorded with a confidence score; weeks later you can run a search before touching settlement code and avoid repeating the mistake. ## Quick Start Ask the assistant to show what has been learned on this project so far, or to record a new learning about a pattern you just discovered.
