incident-response

incident-response is a skill for Claude Code, Codex from nik-kale/sre-skills. It costs 53 tokens per session (1,554 once invoked), scanned A, original, MIT.

A structured guide for investigating production incidents, meaning outages, service slowdowns, or other problems affecting real users.

In plain words
What is it for?
Handling alerts, outages, degraded services, rising error rates, on-call escalations, timelines, severity assessment, and root-cause analysis.
Why use it?
It helps responders establish the impact, gather evidence, coordinate people, and work toward the underlying cause without jumping to conclusions.

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-response 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 11d 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.

Incident Response

Systematic framework for investigating and resolving production incidents.

When to Use This Skill

  • Production alert firing
  • Service outage or degradation reported
  • Error rates spiking
  • User-reported issues affecting production
  • On-call escalation received

Initial Triage (First 5 Minutes)

Copy and track progress:

Incident Triage:
- [ ] Confirm the incident is real (not false positive)
- [ ] Identify affected service(s)
- [ ] Assess severity level
- [ ] Start incident channel/thread
- [ ] Page additional responders if needed

Severity Assessment

Quickly determine severity to guide response urgency:

Severity Criteria Response Time
SEV1 Complete outage, data loss risk, security breach Immediate, all hands
SEV2 Major degradation, significant user impact < 15 min, primary on-call
SEV3 Partial degradation, limited user impact < 1 hour
SEV4 Minor issue, workaround available Next business day

For detailed severity definitions, see references/severity-levels.md.

Data Gathering

Collect evidence systematically. Don't jump to conclusions.

1. Timeline Construction

Timeline:
- [TIME] First alert/report
- [TIME] ...
- [TIME] Current status

2. Key Data Sources

Metrics - Check in this order:

  1. Error rates (5xx, exceptions)
  2. Latency (p50, p95, p99)
  3. Traffic volume (requests/sec)
  4. Resource utilization (CPU, memory, disk, connections)
  5. Dependency health

Logs - Search for:

# Error patterns
level:error OR level:fatal
exception OR panic OR crash

# Correlation
trace_id:<id> OR request_id:<id>

Traces - Find:

  • Slowest traces in affected timeframe
  • Error traces
  • Traces crossing service boundaries

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.
