Conciseness

The five trigger bullets are duplicated verbatim between the 'When to use this skill' section and the frontmatter-derived phrasing, the skillId/reference-id rule is repeated in both Constraints and Workflow step 1, and the three generic EDGE CASE bullets ('stop and ask a clarifying question', 'report the blocker explicitly') restate default Claude behavior. Mostly efficient but with several unnecessary padded sections — the 3 anchor.

Actionability

Concrete guidance throughout: exact file paths ('references/003-skills-inventory.md', 'plinth-skills-generator/src/main/resources/skills.xml'), explicit id-resolution rules ('use the skillId attribute when it exists; otherwise use the single reference name'), and a defined output location. Not a 5 because no example of the output structure appears inline — the actual template shape is entirely delegated to the reference, leaving a minor gap.

Workflow Clarity

A clear three-step sequence (read template and inventory source → generate INVENTORY-SKILLS-JAVA.md → validate coverage) with an explicit validation step ('Verify that the generated file contains every effective skill id… contains no extra skill rows'), so the batch-operation cap does not apply. It falls short of 5 because there is no error-recovery feedback loop (what to do when validation finds missing or extra rows).

Progressive Disclosure

The body is well structured with a dedicated '## Reference' section containing a clearly signaled one-level link (references/003-skills-inventory.md, verified to exist), and bulk detail is appropriately out of the body. Not a 5 because the core template asset assets/java-skills-inventory-template.md — which the task depends on ('following the embedded section template') — is never referenced from SKILL.md itself and is only discoverable via the reference file, adding a second level of indirection.

Specificity

The description names concrete artifacts ('from skills.xml', 'following the embedded section template', 'producing INVENTORY-SKILLS-JAVA.md') but describes essentially one action — generating the checklist — which matches 'names domain and 1-2 concrete actions'. It would be a 4 for the concrete file/artifact specificity, but the rubric's second-person penalty applies: 'Use when you need to generate…' is second-person voice, reducing the score by 1.

Completeness

Both 'what' (generate a checklist document from skills.xml following the embedded template, producing INVENTORY-SKILLS-JAVA.md) and 'when' ('This should trigger for requests such as: …' with five concrete phrases) are explicitly and clearly answered, matching the top anchor exactly.

Trigger Term Quality

Five explicit natural trigger phrasings are listed — 'Create Java system prompts checklist', 'Generate INVENTORY-SKILLS-JAVA.md', 'Inventory Java cursor rule skills', 'List available Java system prompt skills' — covering synonyms (create/generate/inventory/list) and the exact output filename, matching the comprehensive-coverage anchor. It does not fit the 4 anchor because no common natural variation is missing.

Distinctiveness Conflict Risk

The Java-specific niche and unique output filename (INVENTORY-SKILLS-JAVA.md) give it distinct triggers with minimal conflict risk, but 'Part of Plinth Toolkit' signals a family of sibling inventory skills whose phrasing could overlap — mostly distinct with minor overlap risk against closely related skills, so not the 5 anchor.
