SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Query the user's Second Brain vault without writing vault Markdown files. Use when the user asks "检查下我的第二大脑", "查旧知识", "第二大脑里有没有", "what do I know about", or asks where a topic should live in the Second Brain. Uses Basic Memory search first with one search-only reindex before Grep fallback, indexes as navigation only, domain-placement mode for read-only routing advice, daily only for explicit journal/timeline evidence, synthesis with wikilink citations for wiki pages, and explicit handoff to ingest for any write or web expansion.

Core Features & Use Cases

  • Read-only vault queries: retrieve relevant pages without modifying vault content.
  • Domain-placement and synthesis: route queries, provide wikilink citations, and hand off for ingest if writes are needed.
  • Safe retrieval workflow: respect read-only boundaries and avoid web searches; supports a mock reindex step to repair local indexes if needed.
