Perform exhaustive analysis of a critical IOC. Use when an IOC needs Tier 2+ investigation beyond basic enrichment - includes GTI pivoting, deep SIEM searches, correlation with related entities, and threat attribution. For escalated IOCs requiring comprehensive investigation.
Complete Tier 1 triage workflow. Orchestrates the full alert triage process: check-duplicates, triage-alert, enrich-ioc for each entity, and either close (FP/BTP) or escalate (TP/Suspicious). Use for end-to-end alert processing.
Complete Tier 2 investigation workflow. Orchestrates deep investigation of escalated cases: deep-dive-ioc, correlate-ioc, specialized triage (malware/login), pivot-on-ioc, and generate comprehensive report. Use for escalated cases requiring thorough analysis.
Close a case or alert with proper reason and documentation. Use when triage determines an alert is FP/BTP or investigation is complete. Requires artifact ID, type, closure reason, and root cause.
Check for existing SIEM alerts and case management entries related to IOCs. Use to understand if an indicator has triggered previous alerts or is part of ongoing investigations. Takes IOC list and returns related alerts and cases.
Add a comment to a case to document findings, actions, or recommendations. Use to maintain audit trail during investigations. Requires CASE_ID and comment text.

Identify potentially duplicate or similar existing cases before starting deep analysis.

Extract the list of similar case IDs from the response.

SIMILAR_CASE_IDS | List of case IDs identified as potentially similar/duplicate |
SIMILARITY_CHECK_STATUS | Success/failure status of the check |
1. Check duplicates BEFORE enrichment
2. If duplicates found:
- Review similar case(s)
- If confirmed duplicate: close as duplicate
- If related but distinct: note correlation, continue
3. If no duplicates: proceed with analysis
If SIMILAR_CASE_IDS is not empty:
NOT_MALICIOUSSimilar case is already under investigation
