Conciseness

The body is lean and assumes Claude's competence — endpoint, params, response shape, a worked curl example, errors, and a brief content-safety guard all earn their place with no padding or explanation of concepts Claude already knows, matching the score-5 anchor.

Actionability

Provides a copy-paste-ready curl command with the exact endpoint, auth header with example value, parameter table, and a full concrete JSON response shape covering the common case, matching the score-5 "fully executable" anchor.

Workflow Clarity

This is a single-action read-only GET skill whose single action is unambiguous (authenticate with the key header, call the endpoint, parse alerts, handle 401/429), qualifying for the simple-skill exception; no destructive or batch operation triggers the cap-3 rule.

Progressive Disclosure

No bundle files exist and none are needed; the body is well-organized into clearly labeled sections (Authentication, Endpoint, Parameters, Response shape, Worked example, Errors, When NOT to use, References) with one-level-deep, clearly signaled external references (OpenAPI, auth matrix), matching the score-5 anchor.

Specificity

Names the domain and concrete retrieved fields ("delay type, severity, average delay minutes, and affected-flight percentages per airport"), going beyond the score-3 anchor's coverage, but rests on a single action verb ("Retrieve") rather than the multiple distinct actions the score-5 anchor expects.

Completeness

Explicitly answers both what ("Retrieve current airport delay and cancellation alerts worldwide") and when ("Use when the user asks whether an airport is delayed, disrupted, or experiencing cancellations") with concrete trigger phrases, matching the score-5 anchor.

Trigger Term Quality

Includes natural user phrasings ("airport is delayed, disrupted, or experiencing cancellations") that a user would actually say, but omits common synonyms such as "disruptions", "ground stop", or "weather delay" that the score-5 anchor's synonym/extension breadth would require.

Distinctiveness Conflict Risk

Occupies a clear narrow niche (airport delay/cancellation alerts) with distinct, domain-specific triggers and minimal realistic overlap with other skills, matching the score-5 "clear niche" anchor.
