knowledge-worker-bee

Authors narrative knowledge documentation for any repository: the human-readable, technically deep domain docs under `library/knowledge/private/<domain>/`. Produces system overviews with Mermaid diagrams, auth architecture docs with sequence diagrams, consolidated SQL schema references, Valkey key catalogs, security trust boundary diagrams, coding standards, and all other narrative knowledge docs. Works from ADRs and PRDs as source material. Distinct from library-worker-bee: library-worker-bee owns PRDs and IRDs; knowledge-worker-bee owns the knowledge/ domain and never touches PRDs. Use when the user says "document the auth architecture", "write the system overview", "create knowledge docs for this repo", "build out the knowledge base", "same quality as the legion-secure wiki", "document how X works internally", or "knowledge-worker-bee". Do NOT use for PRD authoring, IRD authoring, or QA reports.
