Conciseness

The body is short and lean with no explanations of concepts Claude already knows, and commands are shown rather than described. The "PilotDeck Migration Note" section (source temp path, review status) is process noise that earns no tokens, and the opening sentence duplicates the frontmatter description, keeping it just below the 'every token earns its place' anchor.

Actionability

Six copy-paste-ready curl commands cover the common cases (one-line "format=3", compact "?0", full, v2, and 1-day views, plus New+York showing multi-word locations), followed by the %l/%c/%t... placeholder table, a composed custom format string, and JSON mode (?format=j1). All commands are fully executable and cover common cases.

Workflow Clarity

This is a simple single-task skill where the action is unambiguous — curl "wttr.in/<location>" — and the required input is stated explicitly ("Need a city, region, airport code, or coordinates"). Under the simple-skill exception this scores 5; there are no destructive or batch operations that would require validation checkpoints.

Progressive Disclosure

At ~45 lines with no need for external references (no references/, scripts/, or assets/ directories exist in the bundle), the content is appropriately contained in a single well-organized file with clear Commands, formats, JSON, and Notes sections. The small-skill rule allows a 5 with just well-organized sections, which this meets.

Specificity

"Current weather and forecasts with wttr.in via curl" names the domain, tool, and concrete capability areas ("locations, rain, temperature, travel planning"), matching the 'names domain and 1-2 concrete actions' anchor. It stays below 4 because everything is expressed as noun phrases with no action verbs, so the concrete actions are implied rather than stated.

Completeness

The 'what' is clear (current weather and forecasts via wttr.in/curl), but there is no explicit 'Use when...' clause; the trailing "for locations, rain, temperature, travel planning" only weakly implies when to use it. Per the guidelines, a missing explicit trigger clause caps completeness at 3.

Trigger Term Quality

Natural terms users would actually say are present — "weather", "forecasts", "rain", "temperature", "travel planning" — giving good keyword coverage. A few natural variations (e.g., "hourly", "conditions", "7-day forecast") are missing, so it does not reach the comprehensive-with-synonyms level of 5.

Distinctiveness Conflict Risk

Weather checks are a clear niche with distinct triggers (weather, forecast, rain, temperature), but "travel planning" is broad and creates minor overlap with general travel or itinerary-planning skills, keeping it at 'mostly distinct; minor overlap risk' rather than 5.
