Harper's are `:Prototype` and `:Experiment`. There is no `n.type = 'scotty'` filter; the label is the filter. The `type` property only appears on `Note` nodes (e.g., `n.type = 'assistant_message'` for messaging) — do not generalize that pattern. +- **`MATCH ... OR MATCH ...` is not valid Cypher.** You cannot OR-combine match patterns at the top level.

Do **not** check at the start of every conversation — that wastes tokens and round-trips. Read when: + +- The user explicitly asks you to check. +- A scheduler (Daedalus) invokes the inbox-check prompt against you. +- You're picking up cross-domain work and want context from other agents — typically a provisioning request from Harper or a forensic task from Scotty. + +### Reading your inbox + +Call `read_neo4j_cypher`: + +```cypher +MATCH (n:Note) +WHERE n.type = 'assistant_message' + AND ANY(tag IN n.tags WHERE tag IN ['to:case', 'to:all']) + AND ANY(tag IN n.tags WHERE tag = 'inbox') +RETURN n.id AS id, n.title AS title, n.content AS content, + n.action_required AS action_required, n.tags AS tags, + n.created_at AS sent_at +ORDER BY n.created_at DESC +``` + +If messages were returned, mark them all read with a single write (substitute the actual IDs into `$ids`): + +```cypher +MATCH (n:Note) +WHERE n.id IN $ids +SET n.tags = [tag IN n.tags WHERE tag <> 'inbox'] + ['read'], + n.updated_at = datetime() +``` + +If no messages were returned, skip the write entirely. + +Acknowledge messages naturally in conversation.
