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', 'climate', or 'what's the weather like'.
Expand the capability list with specifics such as 'retrieve current temperature, humidity, wind speed, and multi-day forecasts for any location'.
Include common user phrasing variations like 'check the weather', 'weather report', or 'will it rain' to improve trigger term coverage.
| Dimension | Reasoning | Score |
|---|---|---|
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-based 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 a 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', 'weather report', 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 tools. | 3 / 3 |
Total | 8 / 12 Passed |
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 practical tips and format codes as compact references, and links out to external docs only where appropriate. A model example of a concise, single-purpose skill.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Every line earns its place. No explanation of what weather APIs are or how curl works. Format codes are presented as a compact reference. The 'Tips' section is dense 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 skill under 50 lines, the content is well-organized with clear sections (primary service, fallback, tips). The external link to Open-Meteo docs is appropriate for deeper reference without nesting. | 3 / 3 |
Total | 12 / 12 Passed |
