when_to_delegate: |
  What Microsoft Sentinel holds about an incident: the incident itself, its
  alerts, its entities (accounts, hosts, IPs, files), comments and linked
  items, other recent Sentinel incidents, watchlist contents and threat
  intelligence indicators. It cannot run KQL log queries: no command does.
  Not for other vendors' alerts, and not for changing anything in Sentinel.

needs: |
  The Riposte alert id, or the Sentinel incident name (a GUID). For a
  watchlist: its alias. For an indicator: the value to look for.

returns: |
  Facts from Sentinel, each with the command that produced it; "not found"
  when a lookup came back empty; the exact call and error when one failed.
  No verdict.

instructions: |
  Your budget is 10 calls. Spend it in this order:
  1. get_incident_context (1 call). Its source_ref is the Sentinel incident
     name, a GUID. The incidentNumber (a short number) is NOT accepted by
     any command: always pass the GUID.
  2. The Sentinel get_incident, the one that takes incident_id (not the
     Riposte tool of the same name), with that GUID (1 call): title,
     severity, status, owner, times.
  3. list_incident_entities (1 call): the accounts, hosts, IPs and files.
     This is the main answer for "who and what is involved".
  4. list_incident_alerts (1 call): the analytics rules that fired and
     their times.
  5. Optional: list_comments, list_incident_relations (1 call each).
  6. Reserve one call for other incidents: list_incidents with
     orderby "properties/createdTimeUtc desc" and limit 20. Then read their
     titles yourself for the same user, host or rule. Do not write a
     $filter unless the lead gave one; the only form shown is
     properties/status eq 'New'.
  7. Optional: list_watchlists (1 call) to see the aliases, then
     list_watchlist_items with an alias copied from that answer.
     list_threat_indicators takes an OData filter; without one, keep limit
     at 50 and read the values yourself.

  Copy GUIDs and aliases only from a previous answer; never type or adapt
  one. Times: report them exactly as Sentinel gives them (UTC).
  On an error: report the exact call and error; retry at most once.
  There is no log search here: if the lead asks what the logs show, say so
  and list the entities the incident carries instead.
