NotebookLM integration: one notebook per hierarchy level

[itdove]

Summary

Optional integration with NotebookLM MCP to enrich Lore's knowledge system with semantic search, LLM synthesis, and audio/visual artifacts — without requiring local Ollama or embeddings.

Each hierarchy level maps to a NotebookLM notebook.

Architecture

lore sync
    ↓ entries per level
NotebookLMAdapter
    ↓ source_add(source_type="text") per entry
NotebookLM notebooks (one per level)
    ↓ notebook_query via MCP
Claude Code gets semantically-rich answers

Configuration

{
  "lore": {
    "integrations": {
      "notebooklm": {
        "enabled": true,
        "sync_on_lore_sync": true,
        "notebooks": {
          "0": "notebook-uuid-project",
          "1": "notebook-uuid-team",
          "2": "notebook-uuid-org"
        }
      }
    }
  }
}

Sync: Lore → NotebookLM

On lore sync, push changes to corresponding notebooks:

• New entries → source_add(source_type="text")
• Updated entries → source_delete + source_add
• Deleted entries → source_delete
• Track source ID mapping in sync state

Query: NotebookLM → Lore

New MCP tool or query option:

query_knowledge(topic="...", use_notebooklm=True)

• Queries NotebookLM notebooks via notebook_query
• Falls back to local FTS5/embeddings if NotebookLM unavailable
• Respects hierarchy priority (query project notebook first, then team, then org)

Bonus Artifacts

NotebookLM provides these for free per level:

• Audio overviews (podcast-style summaries of team knowledge)
• Mind maps of org standards
• Study guides for onboarding
• Flashcards for learning team conventions

Known Limitations

Limitation	Mitigation
~50 sources per notebook	Split by domain: "Team - Auth", "Team - Deploy"
Data hosted by Google	Make integration optional, disabled by default
Requires Google auth	nlm login handles auth
Network latency	Cache NotebookLM responses locally
Not air-gap compatible	Local SQLite + Ollama remains primary path

CLI

# Initial setup: create notebooks for each level
lore notebooklm init

# Manual sync to NotebookLM
lore notebooklm sync

# Generate audio overview for a level
lore notebooklm audio --level 1

Acceptance Criteria

• lore notebooklm init creates one notebook per hierarchy level
• lore sync pushes changes to NotebookLM when integration enabled
• Source ID mapping tracked in sync state
• query_knowledge(use_notebooklm=True) queries notebooks with priority
• Graceful fallback when NotebookLM unavailable
• Integration disabled by default
• Works with NotebookLM MCP tools (source_add, source_delete, notebook_query)

Dependencies

• MVP complete
• NotebookLM MCP server available and authenticated
