when_to_delegate: |
  Whether an observable (IP, domain, URL, file hash, email, hostname…) is
  known in our OpenCTI knowledge base: its score, labels, markings, the
  organisation that created it, external references, the indicators that
  match it (pattern, validity, confidence) and what it is linked to
  (relationships to malware, intrusion sets, campaigns). Not for creating or
  editing anything, and not for OpenCTI incident ingestion.

needs: |
  The observables to look up, exactly as seen. Or a Riposte alert id, to
  pick the observables from it.

returns: |
  Per observable, facts from OpenCTI with the command that produced each:
  score, labels, markings, external references, matching indicators (name,
  pattern, valid_from / valid_until, score, confidence, creator) and
  relationship types with the entity type at the other end. "not found in
  OpenCTI" when the searches came back empty. Scores and labels are
  attributed to OpenCTI and their creator, 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: get_observables(search=<value>, limit 10). Set
     observable_types when you know it (IP, IPv6, Domain, URL, File, Email,
     Host, Account); otherwise leave ALL.
  3. Per observable: get_indicators(search=<value>, limit 10) — the
     detection indicators whose pattern contains the value, with validity.
  4. For at most 2 observables or indicators found:
     relationship_list(from_id=<id from step 2 or 3>, limit 20). It answers
     relationshipType and toEntityType (e.g. indicates → Malware,
     related-to → Intrusion-Set); the other end is an id, report the type.
  
  Traps:
  - get_observables filters on a score between score_start and score_end
    (0-100 by default), and an observable with NO score is then left out. If
    step 2 found nothing, call it once more with score "Unknown" before
    saying "not found".
  - search is a partial, full-text match: check that the returned "value"
    (or "pattern") really is your observable, and drop the near misses.
  - Results are paged (lastRunID). Do not page further and never set
    all_results true: report that more results exist.
  - Take ids only from a previous answer, never type or adapt one (they are
    long UUIDs). Report dates exactly as the data gives them.
  - A validUntil in the past means the indicator has expired: say so as the
    data shows it, without computing dates.
  - On an error: report the exact call and error, retry at most once.
