Quality

Content

85%Weight 40%Scale 1-3

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

The body is concise, well-structured, and gives an unambiguous single-step workflow with built-in validation; the only gap is the absence of a complete worked tool-call example.

Dimension	Reasoning	Score
Conciseness	The body is lean and assumes Claude's competence, with no padding explaining what regex is; every line (intro, examples, parameter spec) earns its place.	3 / 3
Actionability	Specifies the exact tool ('run_js') and a complete parameter schema with typed fields, but provides no fully worked example of an assembled call, falling just short of copy-paste ready.	2 / 3
Workflow Clarity	This is a single-task skill with an unambiguous action (call run_js with the listed fields), and the example_match/example_no_match fields act as a built-in validation checkpoint.	3 / 3
Progressive Disclosure	Under 50 lines with well-organized sections (Examples, Instructions); for a simple skill this clear, the rubric allows a top score on progressive disclosure without external file references.	3 / 3
	Total	11 / 12 Passed

Description

50%Weight 40%Scale 1-3

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 conveys the skill's core function concisely but lacks explicit trigger guidance and the common 'regex' keyword, leaving every dimension at the mid-level anchor.

Suggestions

Add an explicit 'Use when...' trigger clause, e.g. 'Use when the user wants to build, match, find, or validate text patterns with a regular expression.'

Include the common term 'regex' alongside 'regular expression' so the description matches the phrasing users actually say.

Reframe in third-person gerund voice ('Builds a working regular expression from a plain-English pattern description, with an explanation') to match the anchor style and sharpen specificity.

Dimension	Reasoning	Score
Specificity	Names concrete actions ('Describe a text pattern in plain English and get a working regular expression with an explanation') but lists only two actions rather than the multiple specific actions of the level-3 anchor.	2 / 3
Completeness	Clearly states what the skill does but provides no 'Use when...' trigger guidance, which caps completeness at 2 per the rubric guidelines.	2 / 3
Trigger Term Quality	Includes relevant terms ('text pattern', 'plain English', 'regular expression') but omits the most common variation 'regex' and match/find/search phrasings users would naturally say.	2 / 3
Distinctiveness Conflict Risk	The regex niche is fairly distinct, but without explicit trigger terms it could still overlap with general text-processing skills rather than having clearly distinct triggers.	2 / 3
	Total	8 / 12 Passed
