Tools

  Transfer the temporary guest shelf identified by workspace_token to the authenticated MemoStem owner as private pending drafts. Call only after the person explicitly agrees to connect or after the guest shelf reports account_required. This tool never approves or publishes cards.
• connect_memostem ~132 tokens
  Connect or grant knowledge read permission through the host OAuth flow, then show a page of the authenticated owner's topic labels. Never creates knowledge.
• create_card_drafts ~1678 tokens
  Create pending, user-owned general-knowledge card drafts only after clear affirmative consent to specifically named, independently teachable knowledge in the current conversation.

  Issue a new short-lived, one-time mobile or desktop web link for the existing guest shelf. Use only when the person asks to open or recover that shelf. Pass the private workspace_token as a tool argument; never show or put it in a URL. This adds no card and makes the previous view link invalid.
• save_guest_knowledge_bundles ~487 tokens
  Store one to 10 specifically selected, independently teachable general-knowledge bundles from the current conversation in a private temporary MemoStem guest shelf. Call only after a direct request or clear acceptance of a specific proposal. Reuse workspace_token to continue the same shelf, but never
• start_memostem ~150 tokens

• validate_knowledge_bundle ~5432 tokens
  Validate exactly one user-selected, independently teachable general-knowledge bundle without an account and without saving it.
