Conciseness

The body assumes Claude's competence (no concept explanations) and earns most of its tokens with prescriptive detail, but the Step 2 aesthetic-direction worked examples (three topics × three options) and repeated restating of skip-then-restate rules are minor instances of over-explanation that could be trimmed, matching the efficient-with-minor-trim anchor.

Actionability

Concrete executable guidance is present throughout — `AskUserQuestion` option sets, `export const meta: SlideMeta = { title: '…', createdAt: '…', theme: '<theme-id>' }`, `export const design: DesignSystem = { … }`, `<ImagePlaceholder>` from `@open-slide/core`, and the `http://localhost:5173/s/<id>` URL — but full starter code and the self-review checklist are deferred to the sibling skill, leaving minor gaps, matching the mostly-executable anchor.

Workflow Clarity

Eight explicitly sequenced steps with gating ("MUST ask before writing code"), a dedicated Step 7 self-review checkpoint, and a final handoff step form a clear sequence with explicit validation and a feedback loop, matching the top anchor; the write operation is non-destructive (framework files are explicitly off-limits) so no validation cap applies.

Progressive Disclosure

SKILL.md is a lean overview that consistently defers technical detail (file contract, canvas, type scale, palette, layout, assets, starter template, self-review checklist) to the one-level-deep `slide-authoring` skill with clear signals like "lives in the slide-authoring skill" and "Read that skill whenever you need details", with no nested references and well-organized sections, matching the top anchor.

Specificity

"create, draft, author, or generate new slides / a presentation" names the slide-authoring domain with concrete verbs, but the four verbs are near-synonyms for a single capability rather than a comprehensive set of distinct actions, matching the anchor for domain + 1-2 concrete actions.

Completeness

It explicitly answers both what (create/draft/author/generate slides) and when ("Use this skill when the user wants to..." plus concrete trigger phrases and the `slides/` path trigger), with an explicit negative boundary, matching the anchor for clearly answering both what AND when.

Trigger Term Quality

Quotes natural phrases users actually say — "make slides about X", "make a deck about X", "create a presentation", "draft slides for", "new slide" — covering synonyms (slides/deck/presentation) comprehensively, matching the top anchor.

Distinctiveness Conflict Risk

Scoping to "this open-slide repo", the `slides/<id>/` path trigger, and the explicit "Do NOT use for editing the framework itself" carve out a clear niche with minimal conflict risk, matching the top anchor.
