“BeeRad”andClaude Sonnet 4.5 be675be4e0 feat: MCP server v1.2.0 — guide system + read/write guide tools
Adds full guide system to MCP standalone server. System guides (schema,
creating-nodes, edges, dimensions, extract) are bundled and immutable.
Users can create up to 10 custom guides via rah_write_guide. Syncs guide
infrastructure from main repo to OS repo app code.

Extract Extraction pre-check. When to reuse chunks vs re-extract. true

Content Extraction

Pre-Check (REQUIRED)

Before running any extraction tool, always check the node first:

  1. Call getNodesById on the target node

  2. Check chunk_status:

    • 'chunked' → content already extracted. Reuse existing chunks. Do NOT re-extract.
    • 'pending' or missing → safe to extract
    • 'failed' → previous extraction failed, safe to retry
  3. Check if embeddings are available (chunk length > 0)

    • If available, use searchContentEmbeddings instead of re-extracting

Extraction Tools

  • youtubeExtract — YouTube videos (requires URL with video ID)
  • websiteExtract — Web pages (uses Jina.ai for JS-rendered sites)
  • paperExtract — PDF files (requires direct PDF URL)

After Extraction

  • The extracted content goes into chunk (full source)
  • AI generates a description (grounding summary)
  • Embeddings are created automatically
  • Assign to relevant dimensions
