Conciseness

The ~30-line body is lean and efficient with no padding or explanation of WordPress concepts Claude already knows; every line is a routing rule or guardrail. It clearly matches the 'lean and efficient; every token earns its place' anchor rather than the 'minor instances of over-explanation' anchor (4).

Actionability

Concrete decision rules for each path ("Use `site-creator` when the user wants a new site, homepage, landing page, or a full site built from a brief"), an explicit tie-break rule ("choose the smallest abstraction that cleanly solves it"), and a worked example (WooCommerce for "Set up an ecommerce system"). As an instruction-only skill, the guidance is fully actionable; not a 4 because the rules cover the common cases with specific, executable direction (only a trivial typo, "aleady", mars it).

Workflow Clarity

This is a simple, single-purpose skill under 50 lines whose single action — pick a path and hand off — is unambiguous, with ownership, routing rules, and guardrails cleanly sequenced and an explicit tie-break for ambiguous requests. No destructive or batch operations exist, so the validation cap does not apply; it is not a 4 since the decision flow has no gaps.

Progressive Disclosure

Under 50 lines with no need for external references (no references/, scripts/, or assets/ bundle files exist) and well-organized sections (Ownership, Routing rules, Guardrails); the referenced specialist skills are siblings it routes to, not buried bundle content. This matches the simple-skill exception where well-organized sections alone earn a 5.

Specificity

The description names the domain ("WordPress build and audit requests") and one concrete action ("Route ... to the right implementation path") plus the five candidate paths, but does not list several distinct concrete capabilities. It sits at the '1-2 concrete actions, not comprehensive' anchor rather than 'several specific actions' (4).

Completeness

It explicitly answers what ("Route WordPress build and audit requests to the right implementation path for a Studio-backed site") and when ("Use when the user wants WordPress work and it is not yet clear whether the task should be handled as site creation, theme work, a custom block, a plugin, or an audit") with concrete trigger phrasing including the ambiguity condition. It is not a 4, since the when-clause is fully explicit rather than merely present.

Trigger Term Quality

Natural trigger terms like "WordPress work", "site creation", "theme work", "a custom block", "a plugin", or "an audit" give good keyword coverage, but common variations users would say (e.g. "website", "redesign", "landing page") are absent. This matches 'good keyword coverage; a few natural terms missing' rather than comprehensive coverage (5).

Distinctiveness Conflict Risk

It occupies a clear niche — the top-level decision maker that routes to specialist skills (site-creator, theme-creator, etc.) — with distinct triggers and minimal conflict risk. It is not a 4 because the router role is explicitly framed and unlikely to fire for the specialist skills' own triggers.
