recall

Search long-term memory for what is already known about the user, project, or topic — call this before your first reply and whenever the topic shifts. Always pass the active namespace when known. Returns matching key clusters only (not memory content): canonical concept, aliases, key type, match score, linked-memory count, hub status, and specificity. For a core lookup, complete read_key(key_id, original_query, namespace) then read_memory(memory_id, via_key_id, namespace): only the full read grows depth/access, reinforces the traversed edge, and learns aliases. Use short focused noun queries and decompose multi-fact questions into several recall calls. inject:true is only an unconfirmed passive preview and must not replace that traversal; injected memories are not reinforced. inject_top_k defaults to 1; inject_max_chars defaults to 2000 and marks truncated previews. An empty result returns {status:'no_match', nearest_keys} — the closest stored concepts below the gate; retry with one of those concepts when relevant.

browse_keys

Browse the vocabulary of one namespace when recall has no hit or you need an entry point. Returns active key clusters with hubs first, then by linked-memory count. This is index metadata only; continue with read_key(key_id, query, namespace) and read_memory(memory_id, via_key_id, namespace).
