Conciseness

Much of the reference material (Article 5 practices, Annex III areas, role definitions) is genuinely beyond Claude's reliable recall and earns its place, but the closing hook is repeated in steps 4, 5, and again in the 'Why this skill does NOT auto-derive obligations' section, and the intro re-states the per-system concept already in the description; not score 1 because the legal reference content is legitimate, not score 3 because of the duplicated hooks and justificatory prose that could be tightened.

Actionability

Gives concrete executable guidance — exact config/inventory file paths, an argument dispatch table, named required fields, a distinguishing test per role, and a copy-paste YAML record format; not score 2 because guidance is specific and complete rather than pseudocode or abstract description.

Workflow Clarity

Multi-step process is clearly sequenced (read config, read inventory, dispatch, then sub-flows) with explicit checkpoints: prohibited→stop and route, dual-role/substantial-modification→re-run classify, and confirm-before-write in edit; not score 2 because validation/verification checkpoints are explicit rather than implicit.

Progressive Disclosure

Single ~240-line monolithic file with no bundle files and no one-level-deep references; the Article 5 and Annex III reference lists are well-sectioned but inline where they could be split into a reference file; not score 1 because sections are clearly organized, not score 3 because content that could be separated remains inline and nothing is split across files.

Specificity

Enumerates concrete capabilities — tracking role (provider, deployer, importer, distributor, authorized representative, product manufacturer) and tier (prohibited, high-risk, limited, minimal, GPAI, GPAI+systemic) — matching the 'lists multiple specific concrete actions' anchor; not score 2 because it goes beyond naming a domain to itemizing the actual actions.

Completeness

Clearly answers both what (per-system role/tier tracking) and when via an explicit "Use when the user says..." clause; not score 2 because the when-trigger is explicit, not merely implied.

Trigger Term Quality

Provides natural phrases a user would actually say — "ai inventory", "add an ai system", "what systems do we have", "classify this ai system", "eu ai act register", "ai system registry" — giving good coverage; not score 2 because it lists six natural variations rather than a few jargon terms.

Distinctiveness Conflict Risk

Occupies a clear EU AI Act niche with distinct, domain-specific triggers unlikely to fire for other skills; not score 2 because the scope is sharply bounded rather than overlapping with generic inventory or compliance skills.
