Conciseness

The body is mostly efficient — tables, decision trees, and a checklist with no explanations of concepts Claude already knows — but the full SKILL.md template (lines 44-78) is inlined while a near-identical copy exists in assets/SKILL-TEMPLATE.md, a clear tightening opportunity. This fits "mostly efficient but could be tightened" rather than the minor-trim level of 4.

Actionability

Concrete guidance throughout: a naming-conventions table, a frontmatter fields table, copy-paste registration snippet for AGENTS.md, and an explicit decision tree for assets/ vs references/. It falls short of 5 because the skill gives no actual creation commands (e.g. mkdir/scaffold commands) and its own Commands guidance is placeholder-only ({Common commands}).

Workflow Clarity

Sections are logically sequenced (when to create → structure → template → naming → decisions → registration) and the closing "Checklist Before Creating" plus the registration step act as validation checkpoints. Sequence is implied by ordering rather than explicitly enumerated, and no run-validation step exists, so it fits anchor 4 rather than 5; the skill is non-destructive so the workflow cap of 3 does not apply.

Progressive Disclosure

The assets/ link at the end is a real, one-level-deep bundle file (assets/SKILL-TEMPLATE.md exists), but the body inlines the full template that already lives in that separate file — content that should be separate is inline. This matches anchor 3 ("content that should be separate is inline") despite otherwise good structure and signaling.

Specificity

"Creates new AI agent skills following the Agent Skills spec" names the domain and one concrete action, matching the anchor for 1-2 concrete actions without comprehensive coverage. It is above a score of 2 because the domain is precisely named, and below 4 because no further specific actions (scaffolding, frontmatter authoring, registration) are enumerated.

Completeness

The description explicitly answers what ("Creates new AI agent skills following the Agent Skills spec") and when ("Trigger: When user asks to create a new skill, add agent instructions, or document patterns for AI") with concrete trigger phrases. This matches the top anchor; neither what nor when is vague or implied.

Trigger Term Quality

Trigger phrases "create a new skill, add agent instructions, or document patterns" are natural things a user would say, giving good keyword coverage. It falls short of 5 because common variations and synonyms like "build a skill", "scaffold", "make a skill", or "SKILL.md" are missing.

Distinctiveness Conflict Risk

Skill authoring per the Agent Skills spec is a clear niche with distinct triggers, but "document patterns for AI" is broad enough to risk overlap with general documentation-writing skills. Mostly distinct with minor overlap risk fits anchor 4 rather than 5.
