Quality

Discovery

40%

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 identifies a clear niche (weather data retrieval) with a useful differentiator (no API key). However, it lacks an explicit 'Use when...' clause and could benefit from more trigger terms and specific capability details to help Claude reliably select it.

Suggestions

Add a 'Use when...' clause with trigger terms like 'weather', 'temperature', 'forecast', 'rain', 'tomorrow's weather', or 'what's the weather in [city]'.

List more specific capabilities such as 'retrieve current temperature, humidity, wind speed, and multi-day forecasts for any location'.

Include common user phrasings like 'check the weather', 'will it rain', or 'weather report' to improve trigger term coverage.

DimensionReasoningScore

Specificity

Names the domain (weather) and two actions (current weather and forecasts), plus a notable constraint (no API key required), but doesn't list more specific capabilities like location lookup, multi-day forecasts, or specific data points returned.

2 / 3

Completeness

Describes what it does (get weather and forecasts) but has no explicit 'Use when...' clause or equivalent trigger guidance, which per the rubric should cap completeness at 2, and the 'what' is also fairly thin, placing this at 1.

1 / 3

Trigger Term Quality

Includes 'weather' and 'forecasts' which are natural terms users would say, but misses common variations like 'temperature', 'rain', 'climate', 'tomorrow's weather', or location-based triggers.

2 / 3

Distinctiveness Conflict Risk

Weather is a clear, distinct niche that is unlikely to conflict with other skills. The mention of 'no API key required' further distinguishes it from other potential weather-related skills.

Implementation

100%

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

This is an excellent, lean skill that provides immediately actionable weather-fetching commands with no wasted tokens. It smartly structures two services as primary/fallback, includes concrete examples with expected output, and keeps reference material (format codes, tips) compact. No improvements needed.

DimensionReasoningScore

Conciseness

Every token earns its place. No unnecessary explanations of what weather APIs are or how curl works. Format codes are presented as a compact reference list. Tips are terse and useful.

3 / 3

Actionability

All examples are fully executable curl commands with expected output shown. Format codes, URL encoding tips, and unit options are concrete and copy-paste ready.

3 / 3

Workflow Clarity

This is a simple, single-purpose skill (fetch weather data). The primary/fallback structure is clear, and each service's usage is unambiguous. No multi-step destructive operations require validation checkpoints.

3 / 3

Progressive Disclosure

For a simple skill under 50 lines with no need for external references, the content is well-organized with clear sections (primary service, fallback, tips). The external docs link for Open-Meteo is appropriately placed for deeper exploration.
