The body is mostly efficient, but the "Explain" section restates what a redirect chain is and how Googlebot behaves (concepts Claude already knows), and "Check"/"Code Review" overlap, so it could be tightened rather than earning the lean level-3 anchor.

Guidance is concrete and specific — "update the first redirect to point directly to the final destination URL" and "confirming a single 301 or 302 followed by a 200" — giving actionable instruction without relying on pseudocode; as an instruction-only skill, the absence of code is not penalized.

The Check → Fix → Verify sequence is explicit and includes a verification checkpoint (confirming a single redirect followed by a 200), so it is not capped by the missing-validation rule and matches the clear-sequence-with-validation anchor.

The body is a concise overview with a clearly signaled one-level reference ("see references/rule.md") to a verified real file, keeping details one level deep with easy navigation.

Names the domain and a concrete action ("auditing site redirects") with migration triggers, but does not list multiple distinct concrete actions, matching the 'names domain and some actions, but not comprehensive' anchor rather than the multi-action level 3.

It states what the skill does ("auditing site redirects") and provides an explicit "Use when ..." trigger covering migrations, domain changes, and CMS upgrades, clearly answering both what and when.

"site redirects", "URL migrations", "domain changes", and "CMS upgrades" are natural terms a user would say when requesting this audit, giving good coverage; it is above level 2 because common variations are present rather than partially missing.

The redirect-chain auditing niche with migration/CMS triggers is clearly distinguishable and unlikely to fire for unrelated skills, matching the 'clear niche with distinct triggers' anchor.
