The body is lean throughout — a one-sentence intro, a compact reference table, and concrete rules — with no explanation of concepts Claude already knows; every line earns its place.

It names exact files (e.g. 'packages/kit/src/views/Discovery/', 'ServiceDiscovery.ts') and functions ('useBrowserTabActions', 'uriUtils.validateUrl', 'validateWebviewSrc'); per the instruction-skill note, the absence of code blocks is not penalized because the guidance is concrete and directly actionable.

The six-step Default Workflow is clearly sequenced and ends with an explicit verification checkpoint ('Verify URL validation, deep link handling, DApp provider notifications, and persisted SimpleDB data are still coherent'), satisfying the validation requirement.

The Quick Reference table signals six one-level-deep reference files, all of which exist under references/rules/, keeping the overview compact while pushing detail into well-organized, navigable bundles.

The description enumerates seven concrete capability areas — 'WebView tabs, bookmarks, history, search, URL risk checks, DApp connections, and JSBridge behavior' — matching the anchor for listing multiple specific concrete actions rather than vague language.

It clearly states what the skill covers but contains no 'Use when...' clause or equivalent explicit trigger guidance, which per the judging guidelines caps completeness at 2.

It surfaces natural domain terms a OneKey developer would actually say ('tabs', 'bookmarks', 'history', 'search', 'DApp connections'), giving good coverage; the more technical terms like 'JSBridge' and 'URL risk checks' do not outweigh the natural vocabulary.

'OneKey Browser/Discovery development' carves out a clear product-specific niche with distinct triggers (WebView, DApp connections, JSBridge) that are unlikely to fire for unrelated skills.
