Conciseness

The body is dense with Makepad-specific content Claude does not already know (Size/Flow/Align value tables, turtle-layout model notes, spacer idiom), and every section is compact. Minor trimmable parts — the 'You are an expert...' role boilerplate and the generic margin/padding box-model ASCII diagram that just restates basic CSS knowledge — keep it at anchor 4 rather than 5, but it is well clear of anchor 3's noticeable padding.

Actionability

Four complete, copy-paste-ready Rust examples cover the common cases (basic container, centering, row with spacer, fixed+flexible), backed by concrete property and value tables and a 'When Writing Code' checklist. This matches 'Fully executable; copy-paste ready code or commands; specific examples cover the common cases' — anchor 4's 'minor gaps' do not apply.

Workflow Clarity

The documentation completeness check is a real sequenced procedure with an error branch (read references → on failure, inform the user and fall back to SKILL.md patterns + built-in knowledge → on success, incorporate content), and both task paths have checklists. It stops short of anchor 5 because there is no validation of generated layout code and no retry loop beyond the docs check; it exceeds anchor 3 because checkpoints are explicit, not implicit.

Progressive Disclosure

Structure is good: the body is a compact overview with two clearly signaled, one-level-deep references ('./references/layout-system.md - Complete layout reference', './references/core-types.md'). However, the references/ directory does not exist — the pointers lead nowhere (which the fallback section partially anticipates). That missing-bundle gap fits 'minor organization gaps' at anchor 4 rather than anchor 5's clean navigation; the in-SKILL.md content is self-sufficient, so it stays above anchor 3.

Specificity

The description names the domain ('Use for Makepad layout system') but states no concrete actions or capabilities — it never says what the skill actually does (write layout code, explain sizing, etc.), matching 'Names the domain but actions are minimal or generic'. It is not 1 because the domain and trigger surface are clearly identified, and not 3 because no 1-2 concrete actions are listed at all.

Completeness

The 'when' is explicit ('Triggers on: ...'), satisfying the trigger-guidance requirement, but the 'what' is vague — 'Use for Makepad layout system' describes no capability. This sits between anchor 3 (clear what, weak when) and anchor 2 (when without what); the domain statement plus explicit trigger list keeps it at 3 rather than rewarding a clear what-and-when pairing that would merit 4.

Trigger Term Quality

Good natural-term coverage: 'makepad layout', 'makepad width', 'makepad padding', 'how to center in makepad', plus Chinese synonyms (布局, 宽度, 对齐, 居中). It falls short of 5 because the bare tokens 'Fit, Fill, Size, Walk' are unqualified, and some natural variations (e.g., 'makepad spacing', 'makepad stack') are missing.

Distinctiveness Conflict Risk

'Makepad' is a clear niche with distinct Makepad-qualified triggers, but the unqualified generic words 'Fit', 'Fill', 'Size', and 'Walk' could fire this skill for unrelated requests (e.g., 'fill in a form', 'image size'). This matches 'Mostly distinct; minor overlap risk' rather than anchor 5's 'minimal conflict risk'.
