Conciseness

The body is lean and assumes Claude's competence — no concept explanations, dense numbered steps, a compact error table. Minor trim opportunities keep it below 5: the Output section restates the Instructions, and the Examples section partially duplicates references/examples.md.

Actionability

Guidance is fully executable: an exact directory tree, enumerated required plugin.json fields, the valid category list, component file conventions per plugin type, and copy-paste commands ('pnpm run sync-marketplace', './scripts/validate-all-plugins.sh plugins/[category]/[plugin-name]/', 'jq empty'). The specific examples cover the common command, skills, and MCP cases.

Workflow Clarity

Nine clearly sequenced steps end with an explicit validation step and a fix-before-completion feedback loop ('Fix any reported issues before completion'), reinforced by an error-recovery table and an Output checklist — matching the anchor for explicit validation, feedback loops, and checklists.

Progressive Disclosure

The body links four real, clearly signaled, one-level-deep reference files both inline and in a Resources section. It stays at 4 rather than 5 because the bundle contains orphaned files never referenced in the body (references/ARD.md, references/PRD.md), the references README is placeholder boilerplate mentioning nonexistent files, and error handling is duplicated between the body's table and references/errors.md.

Specificity

The description names the domain and several concrete actions — 'creates new AI assistant code plugins with proper structure, validation, and marketplace integration' — matching the anchor for several specific actions with minor gaps. It falls short of 5 because coverage of the plugin types and workflow is thinner than a comprehensive list, and the garbled opening 'Create automatically creates' slightly muddies the action statement.

Completeness

Both 'what' (scaffolds plugins with structure, validation, and marketplace integration) and 'when' ('Use when…', 'Trigger with phrases like…') are explicitly present, satisfying the anchor for both present with room for improvement. The 'when' is diluted by the over-broad 'generating or creating new content' rather than being sharply scoped, keeping it below 5.

Trigger Term Quality

Natural phrases users would say are present: 'creating a plugin, new plugin, or plugin from template' plus 'scaffold'. This matches 'good keyword coverage; a few natural terms missing' — common variants like 'make a plugin' or 'add a plugin' are absent — so it does not reach the comprehensive synonym coverage of 5.

Distinctiveness Conflict Risk

'Use when generating or creating new content. Trigger with phrases like 'generate', 'create'' is effectively unlimited in scope and would collide with virtually any content-creation skill, matching 'very broad; high overlap risk with many similar skills'. The plugin-specific phrases provide a partial anchor, but not enough to lift it to 3 since 'create'/'generate' are among the most common request verbs.
