The body is lean and assumes Claude's competence — no padding explaining what a product page is or how webshops work — and every section earns its place (Trigger, Core Objective, Workflow, Output Format, Example, Notes). It is not score 2 because there is no unnecessary explanation to tighten.

Guidance is concrete and executable: explicit scrape fields, a strict comparison rule ('strictly less than... < $40.00'), and exact actions `click[buy now]` / `click[back to search]` with worked examples. Per the scoring notes, this instruction-only skill is not penalized for lacking code, and its guidance is actionable. It is not score 2 because the direction is specific and copy-ready rather than pseudocode-like.

The four-step workflow (Parse → Scrape → Verify → Decide) is clearly sequenced with an explicit suitability flag and a binary decision branch serving as a checkpoint; the single-candidate check is non-destructive so the validate→retry cap does not apply. It is not score 2 because the sequence and decision logic are explicit rather than merely listed with implicit checkpoints.

The body is well-organized into clear sections and a real bundle file exists (references/action_guidelines.md), but the body never signals or links that reference via a markdown path — the guideline content overlaps inline rather than being pointed to. It is not score 3 because the one-level-deep reference is not clearly signaled in the body, and not score 1 because the structure itself is clean and not a monolithic wall of text.

The description lists multiple concrete actions — 'checking price, description, features, and reviews' and 'verify it matches the user's requirements' — matching the score-3 anchor of listing multiple specific concrete actions. It is not score 2 because it goes beyond naming only a domain and some actions to enumerate a clear set of verification behaviors.

It explicitly answers what ('Examines a specific product's detailed page... checking price, description, features, and reviews') and when ('Use when you have navigated to a product detail page from search results... before purchasing'). It is not score 2 because the 'Use when...' trigger clause is explicit, satisfying the completeness rubric's bar for a 3.

It includes natural terms a user would say — 'product detail page', 'from search results', 'confirm the product meets all user-specified constraints', 'before purchasing' — giving good coverage of natural phrasing. It is not score 2 because the terms are common user-facing variations rather than a sparse single keyword.

It carves a clear niche — verifying a single product detail page after navigating from search results — with a distinct trigger unlikely to fire for unrelated skills. It is not score 2 because the trigger is specific to the post-navigation product-check context rather than a broad 'works with product files' phrasing.
