Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • dismiss_cluster

    Reflection control: dismiss the crystallization candidate nucleated by the peak edge (id_a, id_b) so it is not re-surfaced. Not a memory operation. Registered as an MCP tool only when TETHER_CRYSTALLIZE is on - see the _register_crystallization_surface() call at the bottom of this module.

  • forget

    Soft-delete a memory by id: marks it no longer current (excluded from recall/the boot index) but keeps the row, reversibly, like consolidation and the forgetting sweep already do. Returns {"forgotten", "existed"}. (Permanent purge is an admin-only CLI operation, not available here.)

  • link

    Create a bidirectional link between two memories by id.

  • recall

    Search memories by keyword and semantic similarity, then follow the usage graph to related memories, most relevant first. Ask in plain language, the way you would ask a colleague ("how do we run the integration tests?", "what did the user decide about the auth library?") - a memory matching some of the words is a hit, and the best match ranks first. Recall BEFORE starting a task, not only when stuck: the index you were given at session start is titles only. Memories from the current project rank slightly ahead of equally-good ones from elsewhere. Each hit carries {id, type, title, body, tags…

  • remember

    Save a durable memory. UPSERTS: a memory of the same `type` with the same (whitespace/case-normalized) `title` is updated in place instead of duplicated, so re-remembering a fact refines it rather than cluttering. Worth remembering: decisions and their reasons, conventions, gotchas that cost time, the user's preferences and how they like to work, facts about the environment (paths, commands, accounts) you had to discover. Not worth it: anything derivable from the code, or a transcript of what you did. Remember it when you learn it, not at the end of the session. Memories of type project/feed…
