Conciseness

The body is code-forward with minimal prose padding and assumes Makepad knowledge rather than re-explaining basics, so it is largely efficient. It stays below level 5 due to trimmable redundancy: the Triggers section duplicates the frontmatter keyword list, and the full Avatar show_text/show_image implementations appear twice (inner impl plus AvatarRef wrappers) where trimmed signatures would carry the pattern.

Actionability

Nearly all sections give complete, realistic Rust with live_design! blocks, derive macros, ids! lookups, and a concrete Best Practices list — strongly executable guidance. Not level 5 because examples depend on undefined helper types and functions (AvatarTextInfo, DisplayStatus, utils::first_letter, State) and the 12 '_base/' production patterns are only named, with no code or path to runnable examples.

Workflow Clarity

The skill is a pattern catalog, and while sections are ordered sensibly (structure → patterns → best practices), there is no explicit workflow for going from a design task to a chosen pattern — no 'if you need X, use pattern Y' decision guidance and no sequenced steps for building a widget (define DSL → derive → impl Widget → impl Ref). It is not level 2 since the material is coherent and each pattern is self-contained, but checkpoints/decision points are missing.

Progressive Disclosure

The body is well-sectioned, but its navigation targets are dangling: the 'Production Patterns' table points to a '_base/' directory and the 'Reference Files' section lists 'references/widget-patterns.md', 'references/styling-patterns.md', and 'references/moly-widget-patterns.md' — none of which exist in the bundle. Since the promised detail files are absent, a reader following the skill's own pointers hits dead ends, matching 'references are buried/broken' at level 2 rather than level 3's 'references present but not clearly signaled' — here they are clearly signaled but missing.

Specificity

The description names the domain ("Use for Robius widget patterns") but lists zero concrete actions or capabilities — it is a bare trigger keyword list with no statement of what the skill provides (e.g., design patterns or best practices for building Makepad widgets). It matches the 'names the domain but actions are minimal or generic' anchor and is above level 1 only because 'Robius widget patterns' is a concrete, specific domain rather than pure abstraction like 'Helps with documents'.

Completeness

Only the 'when' is present ("Use for Robius widget patterns. Triggers on: ...") with no 'what' — the description never states what the skill contains or does. This matches the anchor 'only when is present without what' (example: 'Use when working with documents') and is clearly not level 3, which requires a clear statement of capabilities.

Trigger Term Quality

Good keyword coverage with natural, varied terms — "modal", "collapsible", "drag drop", "reusable widget", "widget design", "pageflip" — plus bilingual synonyms ("可复用", "模态", "组件设计", "组件模式") and API-level terms ("apply_over", "TextOrImage"). It falls short of level 5 because the most natural terms for this domain, 'makepad', 'robrix', and 'moly', are absent even though the body's own Triggers section lists 'robrix widget, makepad component'.

Distinctiveness Conflict Risk

'Robius' and 'apply_over'/'TextOrImage' anchor it to a niche, but the bulk of the trigger terms — "modal", "collapsible", "drag drop", "widget design" — are generic UI vocabulary that would equally fire for React/web/SwiftUI widget work, so overlap with general UI-component skills is real. Not level 4 because the risk goes beyond 'closely related skills' to any frontend widget discussion.
