The body is lean and assumes Claude's competence — each step is a brief directive with no padding or explanation of concepts Claude already knows, and the only prose ("Work through the following steps in order, waiting for user input at each stage") earns its place.

Provides a fully copy-paste-ready HTML block with explicit placement ("FIRST child element inside <div class='testimonials-grid' id='testimonials-grid'>... directly after the opening div tag, before the existing comment") and concrete star-fill examples, matching the anchor for executable, copy-paste-ready guidance.

Seven steps are clearly sequenced with an explicit validation checkpoint — Step 5 previews the testimonial and offers a change-anything feedback loop before the destructive publish in Step 6 — satisfying the validation requirement for a page-modifying operation.

The skill is under 50 lines, single-purpose, and has no bundle files or external references, yet is well-organized into clearly labeled numbered steps, which per the guideline allows progressive disclosure to score 3 on organization alone.

Lists multiple concrete actions — "Collect a testimonial (name, rating, text, email) and publish it to testimonials.html" — naming both the operations and the exact data fields, matching the anchor for several specific concrete actions.

It clearly states what the skill does (collect and publish a testimonial) but provides no "Use when..." clause or equivalent explicit trigger guidance, so per the guideline completeness is capped at 2.

Contains natural terms a user would say ("testimonial", "rating"), but coverage is thin with no common variations such as "review", "feedback", or "endorsement", fitting the anchor for some relevant keywords but missing variations.

The testimonial-collection niche with a concrete target (testimonials.html) is distinct and unlikely to trigger for unrelated skills, matching the anchor for a clear niche with distinct triggers.
