Quality

Content

92%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is an exemplary lean skill: every command is executable, expected outputs are shown, format codes and tips are compressed into scannable one-liners, and the primary/fallback service split is clearly signaled. The only weakness is the Open-Meteo fallback's unspecified geocoding step. Well under 50 lines, it needs no bundle files.

DimensionReasoningScore

Conciseness

The body is lean and dense: copy-paste commands, expected outputs, a one-line format-code table, and terse tips, with no padding or explanation of concepts Claude already knows.

5 / 5

Actionability

Fully executable curl one-liners with sample outputs cover the common cases, but the Open-Meteo fallback's "Find coordinates for a city, then query" gives no concrete geocoding method, leaving that section a minor gap short of copy-paste ready.

4 / 5

Workflow Clarity

This is a simple single-purpose skill where the primary action (curl wttr.in/<location>) is unambiguous, the primary/fallback split is explicitly labeled, and no destructive or batch operations require validation checkpoints.

5 / 5

Progressive Disclosure

Under 50 lines with no need for external reference files; the two well-signaled sections (wttr.in primary, Open-Meteo fallback) plus a docs link give clean, flat navigation, which the simple-skill guideline scores at 5.

Description

53%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is concise and states a clear capability with a useful differentiator (no API key required), but it omits any trigger guidance, so Claude has no explicit signal for when to reach for it. Keyword coverage is thin beyond the bare word "weather". Adding a "Use when..." clause with natural user phrasings would lift both completeness and trigger quality.

Suggestions

Add an explicit trigger clause, e.g. "Use when the user asks about weather, temperature, forecasts, or conditions for a location."

Broaden trigger keywords to include natural variations users say: temperature, rain, humidity, wind, conditions.

Mention one or two concrete capabilities the service exposes (e.g. current conditions, multi-day forecasts, compact one-line output) to raise specificity from 1-2 actions to several.

DimensionReasoningScore

Specificity

"Get current weather and forecasts" names the domain and two concrete actions but stops short of enumerating what the service actually returns (temp, humidity, wind, PNG output), so it matches anchor 3 rather than the broader coverage of anchor 4.

3 / 5

Completeness

The "what" is clear (get current weather and forecasts, no API key required) but there is no "Use when..." clause or equivalent trigger guidance, which caps completeness at 3 per the judging guidelines.

3 / 5

Trigger Term Quality

"weather" and "forecasts" are natural keywords a user would say, but common variations like temperature, rain, conditions, or forecast phrasing are missing, matching anchor 3.

3 / 5

Distinctiveness Conflict Risk

Weather lookup is a clear niche with minimal overlap risk against other skills, but without explicit distinct trigger phrases it matches "mostly distinct; minor overlap risk" rather than anchor 5.
