Conciseness

The body is organized into short, purposeful sections (Process, Skill Structure, Template, Description Requirements, When to Add Scripts, When to Split Files, Review Checklist) with almost no padding. Minor over-explanation can be trimmed — e.g., "The bad example gives your agent no way to distinguish this from other document skills" restates what the adjacent example shows — so it fits 'efficient; minor instances of over-explanation' rather than the fully lean 5 anchor.

Actionability

Guidance is concrete and executable for an instruction-only skill: a copy-paste SKILL.md template, a directory tree, numeric thresholds ("Max 1024 chars", "SKILL.md exceeds 100 lines", "References one level deep"), and good/bad description examples. It falls short of the 5 anchor because of a minor internal inconsistency — "Additional reference files if content exceeds 500 lines" vs. "Split into separate files when SKILL.md exceeds 100 lines" — which leaves the split threshold ambiguous.

Workflow Clarity

The Process section gives a clear three-step sequence (gather requirements → draft → review with user), each with concrete sub-questions, and the Review Checklist provides a post-draft validation checkpoint. There is no error-recovery loop (what to do when a checklist item fails) and the workflow involves no destructive operations, so this sits at 4 rather than the explicit validate/fix/retry structure of a 5.

Progressive Disclosure

The single-file body is well organized with clearly headed sections, and it explicitly teaches one-level-deep reference structure in its own template and checklist; no bundle files exist to score against, and no references are buried. It is not a 5 because at ~117 lines some self-contained material (e.g., the full Description Requirements section with worked good/bad examples) is inlined where a real skill would split it out per its own 100-line guidance, and there are no actual external reference files demonstrating the pattern it prescribes.

Specificity

"Create new agent skills with proper structure, progressive disclosure, and bundled resources" names the domain (agent skills) and one concrete action (create), with the rest being attributes rather than actions. It does not list several distinct actions (e.g., create, validate, refactor, document), so it matches the 'domain plus 1-2 concrete actions' anchor rather than 'several specific actions'.

Completeness

It explicitly answers both: what ("Create new agent skills with proper structure, progressive disclosure, and bundled resources") and when ("Use when user wants to create, write, or build a new skill"). The 'when' clause is present and explicit but could be more specific about contexts or file types, matching the 4 anchor rather than the fully concrete trigger phrase coverage of a 5; it is clearly above the 3 anchor where 'when' is missing or only weakly implied.

Trigger Term Quality

"Use when user wants to create, write, or build a new skill" covers the natural verb variations users would say (create, write, build). A few natural terms are missing (e.g., "SKILL.md", "skill authoring", "slash command"), which fits the 'good keyword coverage; a few natural terms missing' anchor rather than the comprehensive synonym/extension coverage of a 5.

Distinctiveness Conflict Risk

"Create new agent skills" carves out a clear niche (skill authoring) with distinct triggers, giving minimal conflict with unrelated skills. It sits at 4 rather than 5 because there is minor overlap risk with closely related skills (e.g., editing or updating existing skills, or other authoring/documentation skills) that the trigger phrasing does not exclude.
