Rubrics

The following rubric is used to evaluate the execution of this Triage/Response runbook by an LLM agent.

Grading Scale (0-100 Points)

Criteria	Points	Description
Context & Enrichment	25	Correctly extracted entities and enriched them with relevant context (GTI, SIEM).
Analysis & Decision	25	Analyzed the enriched data to make a sound decision (FP/TP, Escalate/Close).
Action Execution	20	Performed the required response actions (e.g., isolation, containment) correctly.
Documentation	15	Clearly documented findings and actions in the case/ticket.
Operational Artifacts	15	Produced required artifacts: Sequence diagram, execution metadata (date/cost), and summary.

Evaluation Criteria Details

1. Context & Enrichment (25 Points)

• 10 pts: Accurately extracted key entities (IPs, users, hashes) from the input.
• 15 pts: Performed necessary enrichment (e.g., enrich_ioc) to gather reputation and history.

2. Analysis & Decision (25 Points)

• 15 pts: Interpreted the context correctly to determine the nature of the alert.
• 10 pts: Reached a logical conclusion or next step (e.g., "Escalate to Tier 2" or "Isolate Host").

3. Action Execution (20 Points)

• 10 pts: Called the correct tools to perform response actions (if applicable) or investigative steps.
• 10 pts: Verified the success of actions or handled errors appropriately.

4. Documentation (15 Points)

• 15 pts: Posted a comprehensive comment or update to the SOAR case summarizing the triage.

5. Operational Artifacts (15 Points)

• 5 pts: Sequence Diagram: Produced a Mermaid sequence diagram visualizing the steps taken.
• 5 pts: Execution Metadata: Recorded the date, duration, and estimated token cost.
• 5 pts: Summary Report: Generated a concise summary of the actions and outcomes.
