# observability-sre-triage

This skill works out why a service is slow or erroring: it reads SLOs, alerts, metrics and logs, then commits to a verdict.

## What it does

Triage here is a hierarchy, not a checklist. The skill starts with SLO status and error-budget burn rate, then active alerting rules, then the golden signals from traces — throughput, latency, error rate. From there it moves to dependency health and infrastructure saturation, and funnels logs down to the lines that explain the failure. Everything is read-only.

Under the hood it runs ES|QL queries and calls the Kibana SLO and Alerting APIs plus the Elasticsearch ML APIs. You need the `elastic` CLI at version 0.2 or higher, with Elasticsearch and Kibana contexts on the same cluster. The floor is Elasticsearch 8.11+ or Serverless. Three ES|QL features ask for more: `FORK` and `TS` need Stack GA 9.4, `CATEGORIZE` needs Stack GA 9.1 and a Platinum licence; all three are GA on Serverless, and each has a fallback where it is used. If the CLI is missing, the skill will not guess credentials or call the HTTP API directly.

Output discipline is the part worth knowing before you install. One verdict — healthy, degraded or unhealthy — plus the reason, stated once. Zero rows mean data is missing, never that the service is fine. A mechanism no signal measured does not make it into the answer. That is a real constraint if you are used to assistants hedging on clear evidence.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add elastic/agent-skills --skill observability-sre-triage -a claude-code
```
```bash
npx skills add elastic/agent-skills --skill sre-triage -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/sre-triage/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/sre-triage/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add elastic/agent-skills --skill sre-triage -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/sre-triage/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add elastic/agent-skills --skill sre-triage -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/sre-triage/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install elastic/agent-skills sre-triage
```

2. **Manually: put the files in place**
- File: `.github/skills/sre-triage/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add elastic/agent-skills --skill sre-triage -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/elastic/agent-skills --path skills/observability/sre-triage
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/sre-triage/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add elastic/agent-skills --skill sre-triage -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/elastic/agent-skills/tree/HEAD/skills/observability/sre-triage/SKILL.md

## When to use it
- get a verdict on whether a service is healthy, with the evidence behind it
- localise a slowdown or error spike to the service, a dependency or its infrastructure
- read SLO status and remaining error budget mid-incident
- funnel a noisy log stream down to the failures that explain the degradation
- find which attribute — version, host, pod, region, route — marks the failing requests

## Example prompts
- Why has the checkout service been slow for the last half hour?
- Show SLO status and burn rate for payments
- Which attributes distinguish the failing requests in catalog?

  Triage a degraded or suspect service end to end: read SLO status and burn rate,
  check active alerting rules and ML anomalies, measure throughput, latency, and error
  rate, assess dependency health and infrastructure saturation, and funnel logs down
  to the failures that explain it. Use when someone asks whether a service is healthy,
  why it is slow or erroring, what is in its logs, or which attribute distinguishes
  the requests that are failing. Also use when someone asks for the query behind any
  of those signals — throughput, latency percentiles, error rate, dependency health,
  or log volume — over APM/OTel traces, metrics, or logs.

# SRE Service Triage

Decide whether a service is healthy, degraded, or unhealthy, and say why. Triage is a hierarchy, not a checklist: SLOs
and alerts define whether the service is failing its contract, trace-derived golden signals describe how it is failing,
dependencies and infrastructure explain where the failure comes from, and logs supply the sentence you put in the
incident channel. Work down the hierarchy until the evidence supports a verdict, then stop.

For authoring and tuning SLO definitions, burn-rate rules, and alert thresholds, use the
**observability-service-reliability** skill. This skill only reads that state. For Kubernetes workload, node, or
control-plane diagnosis — restart loops, OOM kill confirmation, node pressure, admission rejections, stuck rollouts —
hand off to the **observability-k8s-investigation** skill. This skill checks whether a Kubernetes-hosted service is
saturated; it does not diagnose why the pod or the node behind it is failing.
