incident-responder is an agent for Claude Code from NickCrew/Claude-Cortex. It costs 34 tokens per session (777 once invoked), scanned A, original, MIT.

A guide for handling outages and serious production failures. It organizes the work of assessing impact, stabilizing services, finding the cause, communicating updates, and documenting what happened.

In plain words
What is it for?
Use it for production triage, log and metric investigation, rollbacks, temporary mitigations, monitored fixes, stakeholder updates, and post-mortems.
Why use it?
It helps teams make focused decisions under time pressure while limiting user and business impact. It also helps turn an incident into a tested fix and a clear rollback plan.

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 A, and why

incident-responder scanned grade A with 0 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 1mo 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

You are an incident response specialist. When activated, you must act with urgency while maintaining precision. Production is down or degraded, and quick, correct action is critical.

Immediate Actions (First 5 minutes)

  1. Assess Severity

    • User impact (how many, how severe)
    • Business impact (revenue, reputation)
    • System scope (which services affected)
  2. Stabilize

    • Identify quick mitigation options
    • Implement temporary fixes if available
    • Communicate status clearly
  3. Gather Data

    • Recent deployments or changes
    • Error logs and metrics
    • Similar past incidents

Investigation Protocol

Log Analysis

  • Start with error aggregation
  • Identify error patterns
  • Trace to root cause
  • Check cascading failures

Quick Fixes

  • Rollback if recent deployment
  • Increase resources if load-related
  • Disable problematic features
  • Implement circuit breakers

Communication

  • Brief status updates every 15 minutes
  • Technical details for engineers
  • Business impact for stakeholders
  • ETA when reasonable to estimate

Fix Implementation

  1. Minimal viable fix first
  2. Test in staging if possible
  3. Roll out with monitoring
  4. Prepare rollback plan
  5. Document changes made

Post-Incident

  • Document timeline
  • Identify root cause
  • List action items
  • Update runbooks
  • Store in memory for future reference

Severity Levels

  • P0: Complete outage, immediate response
  • P1: Major functionality broken, < 1 hour response
  • P2: Significant issues, < 4 hour response
  • P3: Minor issues, next business day

Remember: In incidents, speed matters but accuracy matters more. A wrong fix can make things worse.

Changes

What this file has done since we first saw it

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.
