Conciseness

The body contains only one-line purpose statements and executable ES|QL commands with zero concept explanations or padding — e.g. 'Start with high-level health checks:' followed directly by commands — so every token earns its place.

Actionability

Copy-paste-ready `elastic es query` commands cover the common RCA cases (scope check via cluster health/SLOs, error-rate by service, timeline bucketing, deploy/restart/config changes, cross-service dependency stats, CPU and network metrics), with a symptom-to-cause table for interpretation.

Workflow Clarity

The five steps (assess scope, timeline reconstruction, correlation analysis, common root causes, resolution documentation) are clearly sequenced and the symptom table acts as a decision aid, but there are no explicit decision checkpoints linking each step's output to the next action or feedback loops on unexpected results. Read-only investigation means the destructive-operation validation cap does not apply.

Progressive Disclosure

A single well-organized file with clean sections and nothing inlined that clearly belongs in a separate bundle, but at ~70 lines it exceeds the under-50-line simple-skill exception and offers no one-level-deep references (e.g. an ES|QL query cookbook) for deeper material.

Specificity

The description names the domain ('root cause analysis on incidents detected by Elastic Observability') and one concrete action, but does not list several specific actions like querying logs, correlating traces, or checking metrics, so it matches the 1-2 concrete actions anchor rather than the several-actions anchor.

Completeness

Both a 'what' ('performing root cause analysis on incidents detected by Elastic Observability') and an explicit 'when' ('Activate when the user reports a production issue, outage, degraded performance, or asks to investigate alerts') are present; the 'what' is somewhat high-level rather than enumerating concrete capabilities, placing it between the 4 and 5 anchors.

Trigger Term Quality

Natural user phrases such as 'production issue, outage, degraded performance, or asks to investigate alerts' give good keyword coverage, though common synonyms like 'incident', 'downtime', or 'error spike' are missing, keeping it below the comprehensive anchor.

Distinctiveness Conflict Risk

'Elastic Observability' pins a clear niche with distinct triggers, but generic root-cause/troubleshooting phrasing creates minor overlap risk with general debugging skills.
