Conciseness

The body is dense and fluff-free — every rule is an Iced-specific invariant like "request_redraw() repaints but does not call view()" rather than concepts Claude already knows. Minor trimming is possible: the pane_grid tab-drag state machine ("Idle → Pressed(origin) → Dragging state machine at an 8px threshold") and theming token routing duplicate detail that belongs in the already-bundled references, keeping it just short of the lean 5-anchor.

Actionability

Guidance is concrete and API-level: exact calls ("shell.request_redraw() and shell.invalidate_layout()", "Rectangle::INFINITE as the viewport"), a WRONG/RIGHT code diff, runnable discovery commands ("ctx7 docs /websites/iced_rs \"<query>\""), and need→example-file tables. It falls short of fully copy-paste-ready because most rules are principles with only one inline snippet, delegating runnable code to the examples/ directory.

Workflow Clarity

The 4-step workflow (classify surface → read canonical example → read guide → debug fallback) is clearly sequenced, and step 4 provides an explicit error-recovery path ("the guide's 'Common failure modes' / 'Gotchas', then guide-animation-debugging.md") naming the three most common failure signatures. No compile/verify checkpoint exists after writing code, so it stops short of the 5-anchor's explicit validation steps.

Progressive Disclosure

Excellent structure: an overview body, a hub ("Full list in references/INDEX.md; load on demand"), and need→file tables, with every cited references/*.md file verified present and one level deep. However, the workflow's step 2 ("Read the canonical example in examples/") and the iced_wgpu/ section point to directories absent from the actual bundle, so the pointers are not fully resolvable as shipped.

Specificity

"Load whenever building or debugging an Iced UI" names the domain (Iced UI) but its only actions — "building or debugging" — are generic, with none of the concrete capabilities (custom widgets, Canvas, Shader, theming, subscriptions) that live in the separate summary field. This matches the 2-anchor "Names the domain but actions are minimal or generic" and falls short of 3, which requires 1-2 concrete actions.

Completeness

The description has an explicit "when" ("whenever building or debugging an Iced UI") but no "what" — nothing states what the skill actually provides (an 0.14 API reference and guides). This is the 2-anchor case "only 'when' is present without 'what'"; it cannot reach 3-4 without stating the skill's function.

Trigger Term Quality

"Iced", "building", "debugging", and "UI" are natural terms a user would say, and "Iced" is the essential trigger. But common variations are missing — "iced-rs", "Rust GUI", "Iced app", "widget" — matching the 3-anchor "Some relevant keywords but missing common variations or synonyms" rather than 4's fuller keyword coverage.

Distinctiveness Conflict Risk

"Iced" is a highly distinctive framework name with a clear niche, and the trigger phrase would not naturally fire for any other skill. Minimal conflict risk matches the 5-anchor "Clear niche with distinct triggers".
