Save important information to long-term memory. Always set collection when the topic is clear: project work → project:, personal tastes → personal:preferences. Use append_to to extend an existing memory instead of creating duplicates. Vector search indexing completes asynchronously within a few seconds after save.

Search long-term memory. Call list_collections when scope is unclear. For GitHub/Notion synced content use collection project: (unified per project) or tags github/notion. Connect at dashboard.memxus.com/integrations. After this tool returns, show the user the pre-rendered block at the end of the tool result verbatim (user_facing_template). Do not repeat the raw context_block. Expand context: if count < total, recall/get_context with exclude_memory_ids + higher max_memories; if count === total, say no more memories without calling the server. Skills: use N → use_skill_in_chat, install N → install_skill, skip N → skip_skill.

Build a formatted context block for the current topic. Omit topic and collection to show the text collection picker (Memxus menu flow). Call list_collections when unsure of the exact slug. Partial collection names are resolved server-side. If the user's first message appears to be a coding task, technical question, or project-related request, call get_context with the detected topic BEFORE responding — do not wait for the user to ask. After this tool returns, show the user the pre-rendered block at the end of the tool result verbatim (user_facing_template). Do not repeat the raw context_block. Expand context: if count < total, recall/get_context with exclude_memory_ids + higher max_memories; if count === total, say no more memories without calling the server.

List recent memories. Filter by collection, tags, or type to browse one group.

Get the full content of a single memory by its UUID (from list_memories or recall).

List memory collections (folders/scopes) for this user. GitHub/Notion syncs appear under project: when unified collections are enabled. Call before scoped recall/get_context when the user mentions a project name.

Delete a specific memory by ID.

Show statistics about stored memories (by type and collection).

Update an existing memory by ID. Use mode replace (default) to patch fields, or append to extend content. Re-embeds only when content changes.
