The Commands, format codes, and Notes are lean and earn their tokens, but the "PilotDeck Migration Note" (source path, review status, platform metadata) is administrative bloat unrelated to using the skill, matching 'Mostly efficient but includes some unnecessary explanation or could be tightened'. Not score 3 because not every token earns its place; not score 1 because the bulk is tight and assumes Claude's competence.

Copy-paste-ready executable curl commands (e.g., curl "wttr.in/London?format=3"), a format-code reference, and a JSON example match 'Fully executable code/commands; specific examples; copy-paste ready'. Not score 2 because the examples are concrete and complete, not pseudocode.

This is a simple single-purpose skill whose single action (querying wttr.in via curl) is unambiguous, so per the simple-skills note workflow clarity scores 3. Not score 2 because the action and scope boundaries (Notes) are clear; no destructive/batch operation requires validation checkpoints.

Under 50 lines with no external references needed and well-organized sections (Commands, Useful formats, JSON, Notes), so per the under-50-lines note progressive disclosure scores 3. No bundle files exist, so structure rather than references is evaluated. Not score 2 because organization is clean and not monolithic.

Quotes "Current weather and forecasts with wttr.in via curl for locations, rain, temperature, travel planning" — it lists multiple concrete capabilities tied to a specific tool, matching the score-3 anchor 'Lists multiple specific concrete actions'. Not score 2 because it goes beyond naming a domain to enumerating distinct capabilities (forecasts, rain, temperature, travel planning).

The "what" is explicit (weather/forecasts via wttr.in curl), but there is no explicit "Use when..." clause — the "when" is only implied by the topic list. Per the guideline, a missing explicit trigger clause caps completeness at 2. Not score 3 because it lacks an explicit 'Use when working with...' trigger; not score 1 because the what is clearly stated.

Natural user phrasings are present: "weather", "forecasts", "rain", "temperature", "travel planning" — terms a user would actually say, matching 'Good coverage of natural terms users would say'. Not score 2 because common variations are well covered rather than partially missing.

"Current weather and forecasts with wttr.in" carves out a clear, distinct niche unlikely to trigger competing skills, matching 'Clear niche with distinct triggers; unlikely to conflict'. Not score 2 because the wttr.in/curl specificity plus weather-only scope makes overlap with other skills unlikely.
