What problem does it solve? Teams lose hard-won knowledge between sessions: patterns discovered during code reviews, pitfalls hit during debugging, and architecture decisions fade from memory. This Skill manages a persistent learnings store so insights captured by gstack workflows stay searchable, current, and exportable. ## Core Features & Use Cases - Browse and search learnings: Show the most recent 20 entries grouped by type, or run keyword searches across patterns, pitfalls, preferences, and architecture notes. - Prune stale knowledge: Detect learnings that reference deleted files or contradict each other, then remove or update them through a guided prompt. - Export and stats: Export learnings as Markdown ready for CLAUDE.md or project docs, view deduplicated counts by type and source, and manually add new entries with confidence scores. - Use Case: Before starting a refactor, run a search to check whether a similar bug was fixed before, then export the curated learnings into your project documentation for the whole team. ## Quick Start Ask the assistant to show what gstack has learned on this project so far.
