Conciseness

Mostly lean — concrete examples ("smoked peppered bacon", "gluten free", "4 ounce (pack of 2)") and no explanation of concepts Claude already knows. Minor trimmable redundancy: the "When to Use" section reiterates the Purpose/description, and the "Action Format" section duplicates content already in references/action_protocol.md. Not 5 because a few tokens don't earn their place.

Actionability

Concrete elements exist — exact action formats ("click[<exact_value>]", "search[<keywords>]"), an example product ID ("B06Y96MXJV"), and an explicit selection order (flavor then size). However, the "Key Logic" section defers the core deterministic logic to "the bundled script `configure_product.py`" with no usage instructions (no invocation command, arguments, or path), and no such script exists in the bundle — a key missing detail that leaves the central execution path non-executable.

Workflow Clarity

The 5-step Core Workflow is clearly sequenced (navigate → parse → match → configure → finalize) with validation checkpoints in Important Notes ("Do not click an option if it does not appear in the current list of clickables", "Always read the full observation after each action") and an error-recovery path ("search[<keywords>] - Use only if you need to go back to search"). Not 5 because the recovery loop is thin — no guidance for what to do when no clickable matches the user's requirement before falling back to search.

Progressive Disclosure

Sections are well-organized for a short skill, but bundle structure is mishandled: the body's only path reference — "the bundled script `configure_product.py`" — does not exist (there is no scripts/ directory), while the one actual reference file, references/action_protocol.md, is never mentioned or linked from the body at all, and its content is partially duplicated inline. This matches "references present but not clearly signaled" rather than the mostly-clear references of score 4.

Specificity

Lists several concrete actions — "performs the click action to load the product page", "identifies available interactive elements (like flavor or size selectors)" to "be configured to match the user's requirements" — with only minor coverage gaps (e.g., purchase finalization is implied, not stated). Not score 3 because more than 1-2 concrete actions are named; not 5 because coverage of the full task (verification, buying) is incomplete.

Completeness

Explicitly answers both questions: what it does ("performs the click action to load the product page and then identifies available interactive elements... to be configured") and when to use it ("This skill is triggered after a candidate product ID is selected from search results") — a concrete, explicit trigger condition. Not 4 because the 'when' is not merely present but specific and unambiguous.

Trigger Term Quality

Good natural keyword coverage for the domain: "product's detail page", "product ID", "search results", "flavor or size selectors", "configure". A few natural terms are missing (e.g., "product page", "purchase options", "buy"), so it falls short of the comprehensive synonym coverage of score 5 but is well above the sparse keyword sets of score 3.

Distinctiveness Conflict Risk

Occupies a clear niche — post-search navigation and configuration of a specific product's detail page — with an explicit boundary ("triggered after a candidate product ID is selected from search results") that distinguishes it from search-phase skills. Minimal conflict risk; the triggers are distinct and domain-specific.
