    Why it is in this group

    • The name "create_mnemon_relationship" says "create": a word for a change.
    Description, as the server wrote it
    Create a relationship between two mnemon entries. The label decides everything: its kind (containment or association) and how it reads (one_way or mutual) belong to the word itself — never send a per-edge override. All 16 labels: MEMBER (NPC ∈ Faction, mutual), ALLY (mutual), ENEMY (one-way), RIVAL (one-way), PARENT_OF (Location hierarchy — sourceEntryId is the outer/larger place, e.g. Region → City → District → Tavern), CONTAINS (Location → NPC present there), LOCATED_IN (NPC → Location; inverse of CONTAINS), HAS_SUBQUEST (Quest → subquest Quest), QUEST_GIVER (Quest → the NPC who gives it), QUEST_LOCATION (Quest → the Location where it is given or set), QUEST_RELATED_NPC (Quest → NPC), QUEST_RELATED_LOCATION (Quest → Location), SESSION_ATTENDEE_CHARACTER (SessionSummary → a character's Player), SESSION_ATTENDEE_NPC (SessionSummary → NPC), SESSION_FEATURED_QUEST (SessionSummary → Quest), SESSION_FEATURED_LOCATION (SessionSummary → Location). sourceEntryId is the 'from' side; targetEntryId is the 'to' side — which end is which matters. Call describe_mnemon_types for the full valid (sourceType, label, targetType) matrix. For faction membership prefer memberNpcEntryIds on the faction or affiliationEntryIds on the NPC; for a quest's giver, location and parent prefer giverId / locationId / parentQuestId on the quest, which keep each to one link. Session-summary links have no array equivalent — the SESSION_* labels are the only way to set them.

    Create Quest mnemons: a header (status, kind, playersCanTick, hook, and giverId / locationId / parentQuestId links) and a body of objectives (with sub-objectives), reward chips, a Markdown background and GM-only gmNotes. The server builds the quest the Argo app shows from these. Do not write objectives or rewards as Markdown; markdown alone becomes the Background. The retired quest board fields (steps, reward rows, issuer*, questStatus) are for quests the migration has not converted — see describe_mnemon_types.questBody.

    • The name "update_mnemons_content" says "update": a word for a change.
    Description, as the server wrote it
    Edit the body content of one or more mnemon entries. Each item carries an entryId and an ordered list of ops (append, insertAfter, replace, remove) applied atomically per entry. Op content is authored as Markdown (headings, lists, quotes, code fences, bold/italic, links) — do NOT send HTML. Mentions: @[label](mnemon:<entryId>). Images: ![caption](asset:<assetId>@<campaignId>) — upload the asset first; inline base64 / data: URLs are not accepted. Node addressing: get body-node ids from get_mnemon, then target them in replace/remove/insertAfter. A single op's Markdown may produce several nodes; new nodes get fresh server-generated ids (replace keeps the original id on the first new node). On a bad op (missing blockId, unknown op, etc.) the whole entry's batch is rejected with the failedOpIndex; no partial mutation per entry. See describe_mnemon_types.blockOps for the full vocabulary.

    Why it is in this group

    • The name "describe_mnemon_types" says "describe": a word for reading.
    Description, as the server wrote it
    Returns a catalog of all mnemon types, their type-specific fields, and the full valid relationship matrix (sourceType → label → targetType). Call this before create_mnemon or create_mnemon_relationship when you are unsure which type or label to use. A person is an NPC and a faction is a Faction; Player and PlayerParty are made only by the server and cannot be created.

    Description, as the server wrote it
    List all Argo campaigns the current grant token has access to, including the access level ("read" or "read+write") for each. Call this first when the user has not provided a campaign ID. Each entry includes both `campaignName` and `id` (shown inline as `[id: …]` and also in structuredContent.idMap). Use the `id` verbatim for any subsequent tool call that takes a `campaignId`. In prose to the user, refer to campaigns by `campaignName`; do not print the raw `id` unless asked.

    • The name "list_mnemons" says "list": a word for reading.
    Description, as the server wrote it
    List mnemon (lore/memory) entries for an Argo campaign. Optional filters: `title` (case-insensitive substring on entry title only) and `type` (e.g. NPC, Location, Quest). To find entries by what they CONTAIN, use search_mnemons instead. Returns up to `limit` entries (default 100); when `hasMore` is true, call again with `offset` = the returned `nextOffset` to fetch the next page. Each entry includes both `title` and `entryId` (shown inline as `[id: …]` and in structuredContent.idMap). Use the `entryId` verbatim for any tool that takes one; refer to entries by `title` in prose to the user.

    Why it is in this group

    • The name "search_mnemons" says "search": a word for reading.
    Description, as the server wrote it
    Full-text search across mnemon titles, tags, and body content (case-insensitive substring). Prefer this over list_mnemons when looking for entries by what they contain — e.g. "what do we know about the Red Oracle?". Each hit reports which fields matched (title/tags/content) and up to 3 body snippets; a snippet's blockId is the same block id get_mnemon returns, so you can target the matched block directly in update_mnemons_content. Only content visible to the current user is searched. Returns at most `limit` hits (default 20, max 50) plus `hasMore`.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
