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 content is an exemplary simple skill: an immediately executable command, a concrete output contract, and a clear return format, organized into clean sections. Its only weakness is a small Timezone Details section that duplicates general knowledge Claude already has.

Suggestions

Trim or fold the 'Timezone Details' section into the expected-output note, since Asia/Dubai being UTC+4 (GST, no DST) is knowledge Claude already has and the Return Format already specifies "GST (UTC+4)".

Optionally state that the %Z field may render as '+04' vs 'GST' depending on the platform's zone data, so the expected-output check is robust.

DimensionReasoningScore

Conciseness

The body is lean — an executable command, expected output format, and return fields with no padding — but the 'Timezone Details' section restates facts Claude already knows (Asia/Dubai is UTC+4, GST abbreviation, no DST), which is a minor instance of over-explanation that could be trimmed; hence 4 rather than 5.

4 / 5

Actionability

The skill provides a fully executable, copy-paste-ready bash command ("TZ='Asia/Dubai' date '+%Y-%m-%d %H:%M:%S %Z'") plus a concrete expected-output format and an explicit return-field specification, covering the single common case completely.

5 / 5

Workflow Clarity

This is a simple single-purpose skill and the single action is unambiguous: run the command, compare against the stated output format, and return the specified fields. No destructive or batch operations are involved, so the validation cap does not apply.

5 / 5

Progressive Disclosure

The skill is under 50 lines, self-contained, and needs no external references; the body is organized into clearly labeled sections (Command, Expected Output Format, Timezone Details, Return Format), which the guidelines state merits a 5 for simple skills with no bundle files.

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 clearly states what the skill does and occupies a distinct niche, but it omits any 'when to use' guidance and lacks natural trigger terms users would actually say. It is functional but below the quality of the reference good examples, which all pair a specific capability statement with an explicit trigger clause.

Suggestions

Add a 'Use when...' clause, e.g. "Use when the user asks for the current time in Dubai, the Dubai/UAE time zone, or GST time."

Include natural trigger phrasings and synonyms users would say, such as "what time is it in Dubai", "current time in Dubai", "time zone", and "GST (UTC+4)".

Consider mentioning the output the caller receives (a bash-derived timestamp plus timezone fields) to sharpen the 'what' beyond 'Instructions for fetching'.

DimensionReasoningScore

Specificity

"Instructions for fetching current Dubai time via bash command" names the domain (Dubai time) and one concrete action (fetch via bash), matching the 'names domain and 1-2 concrete actions' anchor; it does not list several specific actions, so it is not a 4.

3 / 5

Completeness

The description gives a clear 'what' (fetch current Dubai time via bash) but contains no 'Use when...' clause or equivalent trigger guidance, which the guidelines cap at 3; it is not a 2 because the 'what' is specific rather than vague.

3 / 5

Trigger Term Quality

"Dubai time" and "bash command" are relevant keywords, but common natural phrasings users would say ("what time is it in Dubai", "current time in Dubai", "time zone", "GST", "local time") are missing, matching the 'some relevant keywords but missing common variations' anchor.

3 / 5

Distinctiveness Conflict Risk

"fetching current Dubai time" carves out a clear niche with minimal overlap risk against other skills, but the description states no distinct trigger phrases, so it falls short of the anchor-5 example that includes explicit triggers.
