Conciseness

The body is efficient — no explanation of concepts Claude already knows, concrete field lists, and a tight two-branch example. Minor trimming is possible: the 'Trigger' section largely restates the frontmatter description, and the Notes repeat constraints already implied by the workflow. Not 5 due to that small redundancy; not 3 because the excess is minor, not 'some unnecessary explanation' of background material.

Actionability

Fully executable guidance for an instruction-only skill: exact fields to extract (title, price, description snippets, rating, Buy Now availability), an explicit decision rule ('suitable only if ALL hard constraints are satisfied'), concrete actions 'click[buy now]' and 'click[back to search]', an exact output template, and worked examples covering both the suitable and not-suitable cases. This matches the top anchor; a 4 would require missing key details, which are absent.

Workflow Clarity

The four-step workflow (parse requirements → scrape page data → constraint verification → decision & action) is clearly sequenced, and step 3 is itself an explicit validation checkpoint with a strict pass/fail rule feeding step 4's decision. Edge cases are addressed (missing rating does not disqualify; Buy Now must be present in available actions). Not 4 because there are no meaningful validation gaps for this non-destructive, single-item task.

Progressive Disclosure

The body itself is well-organized into clear sections, but the bundle contains 'references/action_guidelines.md' (action format validity, ASIN clicking rules) that is never referenced or linked from SKILL.md — its content is only partially duplicated in the Notes. This matches 'references present but not clearly signaled'; not 4 because an entire bundle file is undiscoverable from the body; not 2 because the body structure itself is good and nothing that belongs in a separate file is inlined.

Specificity

Concrete actions are named — 'checking price, description, features, and reviews', 'verify it matches the user's requirements', 'provides a final suitability assessment with a clear proceed-or-reject recommendation' — with only minor coverage gaps (e.g., attribute matching is implied rather than listed as its own action). Not 5 because the action list is not fully comprehensive; not 3 because several distinct specific actions are given, not just one or two.

Completeness

Explicitly answers 'what' (examines a product page, checks price/description/features/reviews, gives a suitability assessment) and 'when' ('Use when you have navigated to a product detail page from search results and need to confirm the product meets all user-specified constraints before purchasing'). Both are concrete and explicit, matching the top anchor; a 4 would require the 'when' clause to be less specific, which it is not.

Trigger Term Quality

Natural phrases users/agents would say are present: 'product detail page', 'search results', 'price', 'before purchasing', 'proceed-or-reject'. Not 5 because common variations like 'product page', 'verify a product', or 'buy' are missing; not 3 because coverage goes well beyond a single keyword with several natural trigger phrases.

Distinctiveness Conflict Risk

A clear niche (post-navigation product detail verification with proceed-or-reject output) with distinct triggers, but there is minor overlap risk with a closely related webshop search/browsing skill that could also claim 'product page' triggers. Not 5 because of that residual overlap; not 3 because the scope is far more specific than generic document/file skills.
