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

An exemplary short code-skill: executable examples, a clear need-to-tool decision table, and crisp boundary/policy guidance with no wasted tokens. It appropriately defers depth to external article references rather than bundling inline.

Dimension	Reasoning	Score
Conciseness	Lean and efficient with no explaining of concepts Claude already knows; every section (package naming, decision table, boundary policy) earns its place, assuming the model's competence.	3 / 3
Actionability	Provides fully executable, copy-paste-ready TypeScript (correct imports, Value.Check, Compile, validator.Parse) plus a concrete decision table mapping needs to specific APIs.	3 / 3
Workflow Clarity	The decision table sequences the single-choice workflow (need -> which module to use) unambiguously; no destructive or batch operation is involved, so missing validation checkpoints are not a concern.	3 / 3
Progressive Disclosure	At under ~60 lines with no bundle files, it is well organized into clearly headed sections and lists external reference articles one level deep, meeting the simple-skill allowance for a top score.	3 / 3

Description

90%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A concise, well-targeted description that clearly states both capabilities and explicit use-when triggers for a distinct niche. Slightly less granular on listing multiple concrete actions, but strong overall with no fluff.

Dimension	Reasoning	Score
Specificity	Names the domain (TypeBox) and two capabilities ('runtime schema validation' and 'JSON Schema generation'), but these are domain-level capabilities rather than a comprehensive list of multiple distinct concrete actions, matching the score-2 anchor.	2 / 3
Completeness	It explicitly answers both what ('TypeBox patterns for runtime schema validation and JSON Schema generation') and when ('Use when mentioning TypeBox, Standard Schema, or schema-based validation'), satisfying the explicit-trigger requirement.	3 / 3
Trigger Term Quality	'TypeBox', 'Standard Schema', and 'schema-based validation' are precisely the natural terms a user would say when they need this skill, giving good coverage of relevant trigger language.	3 / 3
Distinctiveness Conflict Risk	It occupies a clear niche (TypeBox specifically) with distinct triggers tied to named technologies, making it unlikely to fire for the wrong skill.	3 / 3
