Conciseness

The body is lean and imperative — process, structure diagram, template, thresholds, and checklists with no explanations of concepts Claude already knows. Minor trimmable padding remains (e.g., the rationale line after the bad description example, the version footer), so it sits at anchor 4 rather than 5.

Actionability

Concrete, copy-paste-ready guidance throughout: a complete SKILL.md template with frontmatter, explicit split thresholds ("exceeds 100 lines", "exceeds 500 lines"), good/bad description examples, and the runnable command "python scripts/skill_review_checklist_runner.py path/to/skill-folder". Falls short of anchor 5 because there is no complete worked example of a finished skill.

Workflow Clarity

The 3-phase process (Gather requirements → Draft → Review with user) is a clear sequence, and the "Review Checklist — After drafting, verify" section plus the programmatic runner provide explicit validation checkpoints. Not anchor 5 because the sequence lacks an explicit fix-and-revalidate loop or gating ("only proceed when validation passes") — what to do when the checklist fails is left implicit.

Progressive Disclosure

Sections are clearly organized and the referenced file (references/companion_tooling.md) is real and one level deep, but 3 of the 4 files in references/ (description_design_patterns.md, progressive_disclosure_principles.md, quality_gates_for_skills.md) are never signposted from the body, and the ~145-line body exceeds the skill's own 100-line split rule with inline content (detailed description-authoring guidance) its own criteria would move to a reference file. This matches anchor 3 — structure present, but references not fully signaled and content that should be separate is inline.

Specificity

"Create new agent skills" names the domain and one concrete action, but "with proper structure, progressive disclosure, and bundled resources" lists output qualities rather than additional actions (drafting, reviewing, validating), so coverage is not comprehensive. It matches anchor 3 (domain + 1-2 concrete actions); not 4 because the remainder of the sentence describes attributes rather than several specific actions.

Completeness

Both parts are explicit: what — "Create new agent skills with proper structure, progressive disclosure, and bundled resources"; when — "Use when user wants to create, write, build, or author a new skill" with concrete trigger verbs. The 'when' clause is more specific than anchor 4's example ("Use when working with PDF files"), so it fits anchor 5.

Trigger Term Quality

"Use when user wants to create, write, build, or author a new skill" gives good natural-verb coverage (create/write/build/author are phrases users would actually say). Not 5 because the noun space is only "skill" — no synonyms or artifacts like "SKILL.md", "skill authoring", or "slash command".

Distinctiveness Conflict Risk

Skill authoring is a clear niche with distinct triggers, so it is mostly distinguishable from unrelated skills. Minor overlap risk remains with closely related companion skills (e.g., document-to-skill compilation), which the description does not disambiguate — fits anchor 4 rather than 5.
