Conciseness

The body is lean and assumes Claude's competence — no padding with concepts Claude already knows, and every section (When to Use, Interview, Templates, Naming, Frontmatter, Anti-Patterns) earns its place. It is not a 5 because the frontmatter block is repeated verbatim across all three templates and the 'Related Skills' stub appears three times, minor redundancy that could be factored out.

Actionability

Provides three complete copy-paste markdown templates, a concrete naming regex ('[a-z0-9-]', max 64 characters), a frontmatter field table, and specific anti-patterns — mostly executable guidance for an instruction-only skill. It falls short of anchor 5 because the templates are skeletons with bracketed placeholders and no filled worked example of a real generated skill, and there is no concrete scaffold command (e.g., creating the skill directory).

Workflow Clarity

The sections imply a logical order (Interview → choose a Type → apply the Template → Naming → Frontmatter → File Structure), but there is no explicit end-to-end numbered sequence for creating a skill, and validation checkpoints are absent — nothing tells the author to verify the result (e.g., name matches the directory, description is under 40 words, SKILL.md under 500 lines is only a tip, not a check). This matches anchor 3: sequence present but checkpoints missing or implicit.

Progressive Disclosure

The skill is self-contained (~180 lines) with clean section structure, consistent heading hierarchy, and nothing inlined that clearly belongs in a separate file; navigation is easy. It does not reach anchor 5 because there are no references/ files at all despite the skill advising 'push depth into references/', and the three full templates could be split into a references/templates.md to slim the overview.

Specificity

The description names the domain ('How to create new skills for an agent-native app') and a couple of actions ('documenting a pattern the agent should follow', 'creating reusable guidance'), matching anchor 3: domain plus 1-2 concrete actions, but not comprehensive. It falls short of anchor 4 because the actions are meta-level rather than a list of several specific concrete operations.

Completeness

It explicitly answers both what ('How to create new skills for an agent-native app') and when ('Use when adding a new skill, documenting a pattern the agent should follow, or creating reusable guidance for the agent') with concrete trigger phrases, matching the anchor 5 example pattern exactly. It is not a 4 because the 'when' clause is already explicit and specific with three distinct triggers.

Trigger Term Quality

'Use when adding a new skill, documenting a pattern the agent should follow, or creating reusable guidance' provides good natural keyword coverage users would actually say. A few natural variations are missing (e.g., 'make a skill', 'scaffold a skill', 'new skill'), so it does not reach anchor 5.

Distinctiveness Conflict Risk

The niche is clear (skill creation for an agent-native app) with distinct triggers, but phrases like 'documenting a pattern the agent should follow' and 'creating reusable guidance' carry minor overlap risk with closely related instruction-writing skills referenced in the body (writing-agent-instructions, capture-learnings). This matches anchor 4 (mostly distinct, minor overlap risk) rather than 5.
