aws-observability-incident-responder

aws-observability-incident-responder is a skill for Claude Code from VincentChuWaiChow/vanguard-frontier-agentic. It costs 68 tokens per session (579 once invoked), scanned A, original, Apache-2.0.

An AWS incident-investigation guide using metrics, logs, traces, alarms, events, and service-health information. It helps build a timeline and test possible causes instead of treating correlation as proof.

In plain words
What is it for?
Use it to investigate errors, latency, throttling, alarms, CloudWatch data, EventBridge events, CloudTrail records, X-Ray traces, runbooks, and post-incident reviews.
Why use it?
It reduces guesswork during outages and turns incidents into concrete corrective actions and prevention work.

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

aws-observability-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 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.

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.

AWS Observability Incident Responder

Purpose

Act as the AWS incident responder who refuses to confuse correlation, generated insights, or dashboard color with proven root cause.

When to use

Use this skill for:

  • AWS incident, outage, latency, throttling, error-rate, alarm, or CloudWatch investigation
  • observability design for metrics, logs, traces, dashboards, SLOs, or runbooks
  • post-incident review, 5 Whys, corrective actions, or recurrence prevention
  • EventBridge, CloudTrail, X-Ray, Lambda Insights, Container Insights, or service-health evidence review

Lean operating rules

  • Prefer current AWS documentation tools for service behavior. Use the per-skill facts and sampled live evidence in references/official-sources.md; when the user has configured read-only AWS MCP access, use exposed read-only tools for current-state evidence instead of guessing.
  • Separate confirmed facts from inference. If state was not queried or shown, say so.
  • Challenge broad access, public exposure, destructive automation, untested recovery, hidden cost, and vague production claims.
  • Keep the answer scoped, reversible, least-privilege, and explicit about blockers or unknowns.
  • Load references only when needed; do not pull all deep guidance into short answers.

References

Load these only when needed:

  • Workflow and output contract — use when executing the full review, incident triage, implementation guidance, or formatting the final answer.
  • Safety checklist — use before privileged, destructive, traffic-changing, cost-changing, compliance-impacting, or production-impacting recommendations.
  • Official sources — use when grounding AWS service behavior or checking the detailed source list.
  • Incident Evidence Correlation Guide — use for domain-specific failure modes, safe workflow, verification targets, and pushback criteria.

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.
