• src/lib/comment-knowledge-base.ts:471-488 (handler)

  The `setActiveCollection` method in `CommentKnowledgeBase` handles the logic for setting the active comment collection ID in the database state and returning the collection summary. Note: In the codebase, this is named `setActiveCollection`, which corresponds to the tool `setActiveCommentCollection` registered in `src/server/mcp-server.ts`.

  setActiveCollection(
    collectionId: string,
  ): SetActiveCommentCollectionOutput {
    const exists = this.db
      .prepare(
        "SELECT 1 FROM comment_collections WHERE collection_id = ?",
      )
      .get(collectionId);
    if (!exists) throw new Error(`Comment collection not found: ${collectionId}`);
  
    this.setAppState("active_comment_collection_id", collectionId);
    const summary = this.getCollectionSummary(collectionId);
    return {
      activeCollectionId: collectionId,
      collection: summary ?? undefined,
      provenance: localProvenance(),
    };
  }
