Quality

Content

100%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.

An exemplary lean skill body: executable command, documented arguments, concrete examples, and well-organized sections with no redundancy or over-explanation. It assumes Claude's competence and every token earns its place.

Dimension	Reasoning	Score
Conciseness	Lean and efficient: a brief intro, one command, a compact args table, output fields, and three terse examples with no padding or explanation of concepts Claude already knows.	5 / 5
Actionability	Fully executable copy-paste-ready command with every flag documented and three concrete examples using real values covering expiry, DTE, and as-of-date cases.	5 / 5
Workflow Clarity	A simple single-purpose read-only calculation skill whose single action is unambiguous; no destructive/batch validation cap applies, so the simple-skill exception yields a 5.	5 / 5
Progressive Disclosure	Under 50 lines, single task, references the existing scripts/greeks.py, and is organized into clear sections (Instructions, Arguments, Output, Examples, Dependencies, Timezone) with no nested references.	5 / 5

Description

87%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.

A strong, third-person description that concretely states capabilities and gives explicit "Use when" trigger guidance covering the natural terms users would say. Minor specificity/keyword gaps prevent a perfect score on two dimensions.

Dimension	Reasoning	Score
Specificity	Names the domain and lists concrete actions ("Calculate option Greeks (delta, gamma, theta, vega) and implied volatility") with the specific Greeks enumerated; minor gaps (rho omitted, scope is narrow) keep it just below comprehensive.	4 / 5
Completeness	Clearly answers both what ("Calculate option Greeks... and implied volatility") and when ("Use when user asks about Greeks, delta, gamma, theta, vega, IV, or option sensitivity analysis") with concrete trigger phrases.	5 / 5
Trigger Term Quality	Good keyword coverage with natural user terms ("Greeks, delta, gamma, theta, vega, IV, option sensitivity analysis"); a few natural variants (e.g. "implied volatility" spelled out, "options pricing") are missing, so not a 5.	4 / 5
Distinctiveness Conflict Risk	A clear niche (option Greeks and IV) with distinct, domain-specific triggers and minimal overlap risk with other skills.	5 / 5
	Total	18 / 20 Passed
