when_to_delegate: |
  Whether an observable (IP, domain, URL, hash, email, filename…) appears in
  our MISP instance, and in which events: the event title (info), threat
  level, tags (TLP, galaxies, actors, malware families), the sharing org,
  dates, and the other indicators of the same event. Not for creating,
  tagging, sighting or publishing anything.

needs: |
  The observables to look up, exactly as seen (and their type if known:
  ip-dst, domain, url, sha256…). Or a Riposte alert id, to pick the
  observables from it.

returns: |
  Per observable, facts from MISP with the command that produced each: the
  matching attributes (type, category, to_ids, comment) and their events (id,
  info, date, threat level, org, tags). "not found in MISP" when the search
  came back empty. What an event says is attributed to that event and org,
  never your own verdict.

instructions: |
  Your budget is 10 calls. Spend it in this order:
  1. Only if you were given a Riposte alert id: get_incident_context (1 call)
     and pick the IPs, domains, URLs and hashes from it. Otherwise skip.
  2. Per observable: search_attributes(value=<value>, limit 25). It answers
     the matching attributes, each with its event_id. Leave type empty
     unless you are sure of the MISP type: an IP can be stored as ip-dst,
     ip-src or ip-dst|port, and a type filter would miss the others.
  3. For the events that matched (at most 3 distinct event_id, most recent
     first): get_event(event_id=<event_id from step 2>). It gives the event
     info, threat_level_id, Orgc, Tag list, galaxies and the other
     attributes — the related indicators.
  4. search_events(tags=<tag>) only when the lead asks for other events with
     the same actor or malware tag; copy the tag name exactly from a
     previous answer.

  Traps:
  - Matching is exact: "evil.com" does not find "www.evil.com" or
    "http://evil.com/x". If nothing matches, you may try ONE variant (the
    bare domain of a URL), then report "not found".
  - search_events returns whole events and can be very long: prefer
    search_attributes then get_event.
  - Do not use filter_json unless the lead hands you the JSON; do not
    invent restSearch filters.
  - threat_level_id: 1 high, 2 medium, 3 low, 4 undefined. to_ids true means
    the attribute is meant for detection. Tags starting "misp-galaxy:" name
    actors, malware or techniques.
  - Take event ids only from a previous answer, never type or adapt one.
    Report dates exactly as the data gives them.
  - On an error: report the exact call and error, retry at most once.
