project-brain

Use when the user wants a persistent AI brain, project memory, LLM wiki, personal knowledge base, model handoff memory, architecture/codebase brain, source ingestion workflow, Obsidian vault mirror, cross-project brain coordination, or any workflow combining raw sources, wiki synthesis, MemPalace memory, graphify graphs, logs, audits, health metrics, and session handoffs. This skill initializes and maintains a layered brain where `.brain/raw/` stores immutable evidence, `.brain/wiki/` stores compiled markdown knowledge, MemPalace stores verbatim session memory and user preferences, graphify maps relationships across code/docs/sources, Obsidian MCP mirrors selected wiki pages to the user's vault, and `.brain/state/session-brief.md` lets a future model recover context after a reset or model change.
