The body is lean — a short overview with a currency caveat, a routing table, and a files table — with no re-explanation of concepts Claude already knows; every section earns its tokens.

Provides concrete per-need direction ('Read [alarms.md]', 'Use [alarm-template.ts] as a starting point', the platform-language guide naming convention); as an instruction-only dispatch skill this actionable guidance meets the level-3 bar without inline code.

The routing table is a clear match-need-to-action workflow, and the risky Dynamic Instrumentation row includes explicit validation gating ('Confirm with the user before any create/delete' and the observation → hypothesis → proposed action → expected result loop).

A concise overview points to well-signaled, one-level-deep references, assets, and scripts, all verified to exist, with a files table aiding discovery; content is appropriately split rather than inlined.

Lists multiple concrete actions ('Builds, configures, debugs, and optimizes') across named AWS services and sub-features (Log Insights, EMF, X-Ray, ADOT, Application Signals), matching the level-3 anchor of multiple specific concrete actions.

Clearly answers both 'what' (builds/configures/debugs/optimizes observability) and 'when' via an explicit 'Applies to … OR …' trigger clause, plus a negative boundary; not the level below because the trigger guidance is explicit rather than implied.

The explicit 'Applies to CloudWatch, alarms, dashboards, EMF, X-Ray, traces, CloudTrail, ADOT, monitoring, synthetics/canaries, OR enabling/onboarding/instrumenting a service for Application Signals' clause gives good coverage of natural terms a user would say.

Occupies a clear AWS-observability niche with distinct triggers and an explicit exclusion ('Not for app logging or security threat detection'), making overlap with other skills unlikely.
