Conciseness

The nine-line body contains zero padding: a heading, the move notice with links, a copy-paste install command, and one closing directive. Every token earns its place and nothing explains concepts Claude already knows — a clean match for the 'lean and efficient' anchor.

Actionability

The body provides a fully executable copy-paste command ('npx skills add kostja94/pagina --skill page-builder') and a concrete follow-up directive ('Ask the agent to use page-builder to build a new Contact Page'). It falls short of 5 only because guidance ends at the redirect — there is no instruction for what to do with the deprecated entry itself after migration.

Workflow Clarity

The single redirect action is unambiguous — install the successor, then use it — and the ordering is legible in the prose. It sits at 4 rather than 5 because the install-then-use sequence is implicit in paragraph order rather than stated as steps, and there is no verification that the install succeeded (e.g., checking the new skill is available).

Progressive Disclosure

The skill is under 50 lines with no need for external bundle references (there are no references/, scripts/, or assets/ files), and the body is well-organized with a heading, a code block, and clearly signaled links — satisfying the simple-skill exception. Both links (the contact.md reference and the Pagina repo) are one level deep and clearly labeled.

Specificity

The description names the domain ('Contact Page construction') and a single successor action ('install and use page-builder'), but lists no capability actions of its own — the skill is a deprecation pointer, matching the anchor 'names the domain but actions are minimal or generic'. It is above a 1 because a concrete action (installing page-builder) and a concrete target are explicitly stated.

Completeness

The 'what' is clear ('Deprecated compatibility entry for Contact Page construction... contains no page rules' per the body), but there is no 'Use when...' clause or equivalent trigger guidance, which caps completeness at 3 per the judging guidelines. It is not a 4 because the 'when' is entirely absent rather than merely implicit.

Trigger Term Quality

'Contact Page' is a natural term a user would say, but coverage stops there: 'compatibility entry', 'Pagina', and 'page-builder' are jargon or brand names, and common variations like 'contact form' or 'contact us page' are missing. This matches 'some relevant keywords but missing common variations or synonyms' rather than the good coverage of a 4.

Distinctiveness Conflict Risk

The domain (Contact Page construction) is specific and the successor is explicitly named, but the entry will still match contact-page requests that should route directly to page-builder, creating overlap with its own successor — 'somewhat specific but could still overlap with similar skills'. Not a 4, since the primary conflict (with page-builder itself) is inherent to the entry's purpose.
