Conciseness

The ~25-line body is generally lean with clear sections, but includes minor padding: the 'You are an expert at...' persona framing and 'Key Principles' bullets that duplicate the attribute-priority hierarchy already detailed in references/search_strategy_guide.md. This matches anchor 4 (efficient, minor instances that could be trimmed) rather than anchor 5's every-token-earns-its-place.

Actionability

There is a concrete worked example ('Effective Search: search[size 5 patent-beige high heel]') and specific principles, but the Action Format section ends 'Your final output must be a single action in the exact format:' with no format actually shown — the single most important executable detail is missing. This matches anchor 3 (some concrete guidance but incomplete, missing key details); it is above anchor 2 because the example and principles are concrete, but below anchor 4 because the promised exact output template is absent.

Workflow Clarity

As a simple single-purpose skill, the Core Workflow gives a clear Input → Process → Output sequence, which under the simple-skill note could merit a 5; however the output action's exact format is undefined, leaving the single action not fully unambiguous. Anchor 4 (clear sequence, minor gaps) is the best fit.

Progressive Disclosure

The body itself is well-sectioned, but the bundle contains references/search_strategy_guide.md (attribute priority hierarchy, pitfalls table, workflow integration) that is never referenced or linked anywhere in the body — a buried reference — and its attribute-priority content is partly duplicated inline in 'Key Principles'. Scoring against the actual bundle structure, this matches anchor 3 (references present but not clearly signaled; content that should be separate is inline) rather than anchor 4, whose references are mostly clearly signaled.

Specificity

The description states a concrete input-to-output transformation ('takes structured attributes (e.g., women's size 5 patent-beige high heel) and produces a concise, platform-appropriate search string'), with only minor softness in 'generates effective search keywords'. It lists specific actions with an example rather than the 1-2 minimal actions of anchor 3, but is single-action so not comprehensive enough for anchor 5.

Completeness

Both 'what' ('generates effective search keywords... produces a concise, platform-appropriate search string') and 'when' ('It is triggered after query parsing, when the agent needs to perform an initial product search on an e-commerce platform') are explicitly and concretely stated, matching the anchor 5 example with explicit trigger guidance.

Trigger Term Quality

Natural trigger terms are present: 'product search', 'search keywords', 'search string', 'e-commerce platform', 'query parsing'. Coverage is good but misses common variations or synonyms (e.g., 'search query', 'shopping', 'webshop'), matching anchor 4 rather than the comprehensive synonym coverage of anchor 5.

Distinctiveness Conflict Risk

The description carves out a clear niche — initial search-string formulation on an e-commerce platform after query parsing — with trigger conditions unlikely to fire for unrelated skills, matching anchor 5 (clear niche with distinct triggers, minimal conflict risk).
