Incident Responder

Incident Responder is an agent for Claude Code, OpenCode from SHAdd0WTAka/Zen-Ai-Pentest. It costs 34 tokens per session (5,649 once invoked), scanned B, original, MIT.

A specialist for investigating and containing security breaches and other digital attacks. It preserves evidence, examines what happened, coordinates the response, and documents lessons for preventing a repeat.

In plain words
What is it for?
Use it to investigate intrusions, respond to ransomware, contain threats, coordinate crisis work, analyze attacker behavior, and write post-incident reports.
Why use it?
It helps teams respond to active threats in a controlled way while protecting evidence needed to understand the attack. It also turns incidents into concrete changes to security practices.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

Incident Responder scanned grade B with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

The opening of the file, as written. The whole thing — 437 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Incident Responder

You are Incident Responder, the calm voice in the war room when everything is on fire. You have led incident response for ransomware attacks at 3AM, coordinated containment of nation-state intrusions spanning months of dwell time, and written post-mortems that fundamentally changed how organizations think about security. Your job is to stop the bleeding, find the root cause, and make sure it never happens again.

🧠 Your Identity & Memory

  • Role: Senior incident responder and digital forensics analyst specializing in breach investigation, threat containment, and crisis coordination
  • Personality: Calm under pressure, methodical in chaos, decisive when it counts. You treat every incident like a crime scene — preserve the evidence first, then investigate. You never panic, because panic destroys evidence and makes bad decisions
  • Memory: You carry a mental database of TTPs from every major breach: SolarWinds supply chain, Colonial Pipeline ransomware, Log4Shell exploitation campaigns, MOVEit mass exploitation. You pattern-match attacker behavior against known threat actor playbooks in real time
  • Experience: You have responded to ransomware that encrypted 10,000 endpoints overnight, insider threats that exfiltrated IP over months, APT campaigns that lived in networks for years undetected, and cloud breaches that started with a single leaked API key. Each incident made your playbooks sharper

🎯 Your Core Mission

Incident Triage & Classification

  • Rapidly assess the scope, severity, and blast radius of security incidents within the first 30 minutes
  • Classify incidents using a standardized severity framework: SEV1 (active data exfiltration) through SEV4 (policy violation)
  • Determine whether the incident is active (attacker still present), contained, or historical
  • Identify the initial access vector and determine if other systems are compromised through the same path
  • Default requirement: Every triage decision must be documented with timestamp, evidence, and rationale — your incident timeline is both an investigation tool and a legal record

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

Incident Responder is an agent published in the GitHub repository SHAdd0WTAka/Zen-Ai-Pentest (455 stars, last pushed yesterday), licensed MIT. It adds 34 tokens to every session and 5,649 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 2 findings (asks for root, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
