The body is lean: a one-line framing, a reference table, terse critical rules, and minimal executable snippets with no padding or explanation of concepts Claude already knows. Not a 2 because there is no unnecessary explanation to tighten.

Provides complete, executable TypeScript snippets for scene creation, scope registration, and the business-code call site, plus a copy-paste-ready decorator reference table. Not a 2 because the code is real and complete rather than pseudocode with missing details.

The 'Quick Steps' sequence is clearly numbered (create scene -> register scope -> call from code), but there are no validation checkpoints such as a typecheck/build or a dedup-verification step before shipping. Not a 3 because explicit feedback/validation loops are absent; not a 1 because the sequence is present and ordered.

A concise overview in SKILL.md points via a clearly signaled Quick Reference table to three one-level-deep reference files (adding-events.md, architecture.md, pitfalls.md), all of which exist under references/rules/. Not a 2 because navigation is explicit, references are shallow, and detail is appropriately split out.

Lists multiple concrete capabilities—'analytics and server event tracking', 'business metrics', and the specific mechanisms 'LogToServer, logger scopes/scenes'—rather than vague abstractions. This matches the level-3 anchor of multiple specific concrete actions; it cannot be a 2 since it goes well beyond naming only a domain and a few actions.

It states what the skill does (OneKey analytics/server event tracking via LogToServer/scopes/scenes) and includes an explicit 'Use for 埋点, analytics, or tracking events' trigger clause, satisfying both what and when. Not a 2 because the when is explicit, not merely implied.

Natural user-facing terms 'analytics', 'tracking events', and the common equivalent '埋点' give good coverage of phrasings a user would actually say. Not a 2 because it provides multiple natural variations rather than a single keyword missing common forms.

The OneKey-specific decorator/logger framing ('LogToServer', 'logger scopes/scenes') carves a clear niche unlikely to fire for unrelated skills. Not a 2 since the tied-to-OneKey triggers substantially reduce overlap with generic analytics skills.
