The body is lean (~30 lines) with no explanations of concepts Claude already knows; every section (workflow, decision logic, constraints, example) earns its place and assumes competence.

Provides concrete, environment-specific guidance — the `search[keywords]` action, the single-string-in-brackets rule, and a fully worked example `search[long clip-in hair extension]` — that is copy-paste ready for the WebShop task.

A clear 4-step sequence with an explicit 'Validate Results' checkpoint and feedback loops (re-invoke with a broader query on 0 results, refine terms when prices exceed budget), matching the anchor for validation steps and error recovery.

A simple, single-purpose skill under 50 lines with no external references, organized into clear sections (Core Workflow, Key Decision Logic, Constraints, Example), which per the rubric's simple-skills note merits a 3.

Lists multiple concrete actions — 'Performs an initial product search', 'generating appropriate search keywords', 'inputs structured search parameters and outputs a list of candidate products' — matching the anchor for several specific concrete actions.

Explicitly answers what it does (search, generate keywords, input params, output candidates) and when via a clear 'Use when...' clause with three distinct triggers — not just implied.

Triggers are task/state-based ('starting a product discovery task', 'returning to search results after rejecting a product', 'observation contains a search interface prompt') rather than natural user phrasings; missing common keyword variations a user would actually say.

Occupies a clear niche as the WebShop product search entry point with triggers tied to the search interface, making overlap with unrelated skills unlikely.
