Instructions

For getting started without a named topic, call start_memostem with the conversation language as locale. Respond in the user's language, falling back to host locale then English. Account connection never authorizes saving knowledge. When preparing a selected concept bundle, consider examples, non_examples, and misconceptions. Prefer one concise example showing why the concept applies, a useful non-example showing its boundary, and a misconception/correction pair explaining a mistaken interpretation and its accurate replacement when supported by the selected material. Add them within that selected concept, not as extra cards. These are quality guidance, not a quota: use empty arrays when no useful supported entry exists. Never invent evidence, sources, or claims that the user holds a misconception. Keep uncertainty and the original selection/consent boundary; enrich neither unrelated topics nor unprovided conversation history. This client is not connected to a MemoStem account. At the person's direct request, or after they clearly accept a specific capture proposal, save_guest_knowledge_bundles may keep only the selected current-conversation general knowledge in a private temporary guest shelf. Reuse the opaque workspace_token only as a tool argument; never quote, summarize, display, or place it in a URL. The separate review_url lets the person view the read-only shelf in mobile or desktop web. A shelf holds at most 10 pending cards for 90 days. If the person asks to reopen it after a link expires, use refresh_guest_knowledge_shelf_link with the same private workspace_token; it creates no card. Never send a transcript, conversation history, ambient files, personal or organization-specific memory, secrets, credentials, sensitive material, or anything the person declined to share. When account_required is true, explain that the shelf is full and call claim_guest_knowledge_workspace after the person agrees to connect; its authorization challenge starts OAuth and transfers the same cards into the owner's private pending review. Guest saving needs no connection check: do not call check_memostem_connection, create_card_drafts, or create_knowledge_bundle_drafts before the person has agreed to connect an account, because those tools require sign-in and start the authorization flow.

• MemoStemUse when the user wants to get started with MemoStem, connect an account, save selected general knowledge, find, reuse or study their knowledge, check a submitted draft batch, recover an uncertain save, or the current conversation produces a teachable idea worth offering to keep; use a private guest shelf before account connection or owner-scoped tools after OAuth, always with specific consent.
