Conciseness

The body is code-dense with minimal prose and assumes framework familiarity (no explanations of Rust or generic event concepts). However, the cx.widget_action emit pattern and finger hit-testing are demonstrated twice — once in 'Custom Action Pattern'/'Emitting Actions from Widgets' and again in 'Action Types'/'Event Handling Patterns' — which is minor redundancy that could be trimmed, matching anchor 4 rather than the lean anchor 5.

Actionability

Concrete, realistic Rust examples with real Makepad APIs (widget_uid, scope.path, as_widget_action().cast(), SignalToUI::set_ui_signal) covering the define → emit → handle flow for widget, posted, and global actions. Minor gaps keep it below anchor 5: helper methods like self.get_details() are undefined and how a custom enum actually becomes an Action (derive/trait) is not shown.

Workflow Clarity

The main pattern flow — define action enum with DefaultNone, emit from widget handle_event, centralize handling in App's handle_actions with the four cast patterns — is coherently sequenced, and the Best Practices list acts as a checklist. No destructive or batch operations, so validation checkpoints are not required; it falls short of anchor 5 only in lacking any verification/debug guidance (e.g. what to check when an action is not received).

Progressive Disclosure

The 'Reference Files' section clearly signals three references and describes their contents, but the referenced files (references/action-patterns.md, references/event-handling.md, references/moly-action-patterns.md) do not exist in the bundle — the references/ directory is absent entirely. Per the guideline to score against the actual bundle structure, navigation to deeper content fails and effectively all content is inlined in one ~350-line file, matching anchor 2 ('content that clearly belongs in separate files is inlined') rather than 3.

Specificity

'Use for Robius event and action patterns' names the domain but lists no concrete capabilities; the remainder is a keyword list. This matches the anchor 'Names the domain but actions are minimal or generic' — it is not entirely vague (anchor 1) because the Robius domain is explicit, but it never states what the skill does.

Completeness

The 'when' is explicit and strong ('Use for...', 'Triggers on: ...'), but the 'what' is only implied — the description never says what the skill provides (defining actions, emitting them, centralizing handling, best practices). The weak 'what' keeps it at anchor 3's level rather than 4, which requires both present with a substantive statement of what it does.

Trigger Term Quality

Includes natural phrases users would say ('custom action', 'widget action', 'event handling') plus framework-specific terms (MatchEvent, post_action, cx.widget_action, DefaultNone) and Chinese synonyms (事件处理, 自定义动作). A few natural terms are missing — e.g. 'makepad', 'makepad action' — so it falls short of the comprehensive anchor 5.

Distinctiveness Conflict Risk

Robius/Makepad scoping with distinctive API tokens (MatchEvent, cx.widget_action, DefaultNone) establishes a clear niche, but generic trigger terms like 'event handling' and 'custom action' carry minor overlap risk with general event-handling skills. Mostly distinct, matching anchor 4 rather than the minimal-conflict anchor 5.
