What problem does it solve? AI knowledge bases that only grow become corrupted: CLAUDE.md files balloon past useful size, memory entries turn into implementation narratives, skill indexes fall out of sync with actual directories, and path references silently break after refactors. This Skill turns the quarterly knowledge-base audit into a fixed checklist so decay is caught and repaired on schedule. ## Core Features & Use Cases - Broken Reference & Size Inventory: Runs pnpm knowledge:check plus line-count scans to flag CLAUDE.md files over 400 lines and memory entries over 20 lines. - Memory Triage: Enforces the one-sentence-index convention, merges same-cluster entries, deletes content already absorbed into CLAUDE.md, and greps to verify referenced files and functions still exist. - Skills & CLAUDE.md Governance: Archives skills untouched for 6+ months, fixes descriptions that drifted into summaries, splits oversized CLAUDE.md files into per-directory subdomain docs, and syncs the nested knowledge map. - Use Case: After a large refactor, run the quarterly audit to find three stale memory paths, split a 600-line CLAUDE.md, and archive two dormant skills, finishing with pnpm check fully green. ## Quick Start Ask the AI to run the quarterly knowledge base audit over CLAUDE.md, .claude/skills, and .claude/memory and fix everything it finds.
