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

A tight, well-structured reference skill that assumes Angular competence and splits its one detailed example into a real one-level reference. It is held back only by mild terminology redundancy in the anchors section and the absence of a complete inline code block in the body itself.

Suggestions

Remove or trim the 'Canonical response anchors' section since all five terms are already stated in Principles/Anti-Patterns, or repurpose it as a non-redundant checklist of outcomes to verify.

Inline one small complete copy-paste directive or pipe example in the body so the core case is executable without opening the reference file.

Dimension	Reasoning	Score
Conciseness	The body is lean and assumes Angular competence (no generic concept explanations), but the 'Canonical response anchors' section repeats terms already covered in the body (cache results, host: {} object, imports array, not set pure: false, not with @HostBinding), a minor redundancy that keeps it just below the 'every token earns its place' anchor.	4 / 5
Actionability	Concrete fragments appear throughout ('@Pipe({ name: 'truncate', standalone: true, pure: true })', 'transform(value: string, limit = 50)', 'selector: '[appHighlight]'', host object syntax), but the body lacks a complete copy-paste-ready code block (the full example lives in references/composition.md), matching 'mostly executable guidance; minor gaps'.	4 / 5
Workflow Clarity	This is a principles/reference skill rather than a multi-step workflow, but it is organized in a clear logical progression (Principles → Guidelines → Anti-Patterns) with unambiguous guidance and no destructive/batch operations requiring validation checkpoints, fitting the 'clear sequence with minor gaps' anchor under the simple-skills guidance.	4 / 5
Progressive Disclosure	A short, well-sectioned overview (~35 lines) with a single well-signaled one-level-deep reference ('[Composition](references/composition.md)') that exists as a real file and holds the full code example, matching 'clear overview with well-signaled one-level-deep references; content appropriately split'.	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, concise description that names a specific Angular niche, lists concrete capabilities, provides explicit 'Use for...' trigger guidance, and adds boundary direction to avoid mis-triggering. Minor gaps in keyword synonyms and action variety keep specificity and trigger_term_quality at 4 rather than 5.

Dimension	Reasoning	Score
Specificity	Quotes 'Build custom Angular attribute directives, HostDirectives, and pure pipes' — three concrete actions in a clearly named domain, but all are 'build' variants with minor coverage gaps (e.g., structural directives intentionally excluded), fitting the 'several specific actions; minor gaps' anchor rather than the fully comprehensive 5.	4 / 5
Completeness	Explicit 'what' ('Build custom Angular attribute directives, HostDirectives, and pure pipes') and explicit 'when' ('Use for Angular directive or pipe implementation, including custom attribute directives') with concrete trigger phrases and boundary guidance, matching the 'clearly and explicitly answers both what AND when' anchor.	5 / 5
Trigger Term Quality	Natural Angular terms appear ('Angular directive or pipe implementation', 'custom attribute directives', 'HostDirectives', 'pure pipes') giving good keyword coverage, but common synonyms and file extensions are absent, matching the 'good coverage; a few natural terms missing' anchor.	4 / 5
Distinctiveness Conflict Risk	Clear Angular-specific niche with distinct triggers plus explicit deferral ('defer React/CSS middleware and unrelated framework work'), giving minimal conflict risk per the 'clear niche with distinct triggers' anchor.	5 / 5
