Quality

Content

100%

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, actionable reference: executable curl commands with outputs, a clear primary/fallback split, and useful format codes and tips with no padding. It is a simple, self-contained skill that needs no external references.

Dimension	Reasoning	Score
Conciseness	The body is lean and assumes Claude's competence, with no explanations of concepts Claude already knows; every line (commands, format codes, tips) earns its place.	3 / 3
Actionability	It provides fully executable, copy-paste-ready curl commands with example outputs, concrete format codes, and specific tips (URL-encoding, airport codes, units, PNG), matching the level-3 anchor.	3 / 3
Workflow Clarity	This is a simple, single-purpose skill with a clearly organized primary (wttr.in) and fallback (Open-Meteo) structure and no destructive or batch operations, so per the simple-skills note the unambiguous single action scores 3.	3 / 3
Progressive Disclosure	The skill is under 50 lines, needs no external bundle files, and is organized into well-labeled sections, so per the simple-skills note well-organized sections alone warrant a 3.	3 / 3
	Total	12 / 12 Passed

Description

50%

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 third-person with a clear domain, but it states only the 'what' and omits any explicit 'when to use' trigger guidance. It lists just two actions and a narrow set of natural keywords, leaving it solid but not exemplary.

Suggestions

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

Broaden natural keyword coverage to include terms users actually say, such as 'temperature', 'conditions', 'rain', and 'humidity'.

Expand the action list slightly to make capabilities more concrete, e.g. 'Get current conditions, multi-day forecasts, and compact one-line weather output.'

Dimension	Reasoning	Score
Specificity	The phrase 'Get current weather and forecasts' names the weather domain and two actions (current weather, forecasts), but it is not a comprehensive list of multiple concrete actions, so it matches the level-2 anchor rather than level 3.	2 / 3
Completeness	It clearly states what the skill does ('Get current weather and forecasts') but lacks any 'Use when...' or equivalent explicit trigger guidance, which per the guidelines caps completeness at 2.	2 / 3
Trigger Term Quality	'weather' and 'forecasts' are natural terms a user would say, but common variations like 'temperature', 'conditions', or 'rain' are missing, matching 'some relevant keywords but missing common variations'.	2 / 3
Distinctiveness Conflict Risk	The weather domain is a fairly clear niche, but the description is bare and lacks explicit triggers, so it could still overlap with similar general-purpose skills rather than being unmistakably distinct.	2 / 3
