Content

100%

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

A well-structured, lean skill body built on executable BAD/GOOD code pairs, an ordered audit checklist with explicit test-validation, and a verification checklist with concrete thresholds. It assumes Claude's competence and stays highly actionable throughout.

Dimension	Reasoning	Score
Conciseness	Lean BAD/GOOD code pairs with terse rules and no explanation of basic concepts Claude already knows; the 'Validated by' lines and Quick Reference table are scannable aids, not padding. Not 2 because there is no unnecessary explanation to tighten.	3 / 3
Actionability	Provides executable TypeScript with exact import paths and concrete commands such as 'npm run perf:chat-leak --messages 20 --verbose', copy-paste ready. Not 2 because the examples are complete and executable, not pseudocode.	3 / 3
Workflow Clarity	Sequences an ordered 6-step audit checklist with a dedicated test-validation step and a Verification section containing explicit thresholds (slope > 2 MB/msg). Not 2 because validation checkpoints are explicit, not missing or implicit.	3 / 3
Progressive Disclosure	A self-contained pattern catalog with well-organized sections (When to Use, Audit Checklist, Quick Reference, Verification) and a single clearly-signaled cross-skill pointer (chat-perf); no bundle files exist, so well-organized sections suffice. Not 2 because structure and navigation are clear rather than disorganized.	3 / 3
	Total	12 / 12 Passed

Description

100%

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 states a concrete capability, lists specific covered APIs, and provides an explicit 'Use when' trigger clause covering several natural phrasings. It is concise and clearly distinguishable from other skills.

Dimension	Reasoning	Score
Specificity	States the concrete action 'Audit code for memory leaks and disposable issues' and enumerates specific APIs (addDisposableListener, Event.once, MutableDisposable, DisposableStore, onWillDispose), matching the 'lists multiple specific concrete actions' anchor. Not 2 because it names exact APIs rather than just a domain.	3 / 3
Completeness	Explicitly answers what ('Audit code for memory leaks and disposable issues') and when ('Use when reviewing event listeners... or fixing leak reports') with an explicit 'Use when' clause. Not 2 because the trigger guidance is explicit, not merely implied.	3 / 3
Trigger Term Quality	Includes natural developer phrases a user would actually say — 'reviewing event listeners, DOM handlers, lifecycle callbacks, or fixing leak reports' — giving good coverage. Not 2 because multiple common variations are present rather than a single keyword.	3 / 3
Distinctiveness Conflict Risk	Targets a narrow VS Code disposable/leak niche with highly specific API names, making it unlikely to fire for unrelated skills. Not 2 because the niche and triggers are clearly distinct, not broadly overlapping.	3 / 3
	Total	12 / 12 Passed
