Conciseness

The body is dense and actionable with no known-concept padding, but Step 2 inlines ~9 example aesthetic options across three topics where one would demonstrate the pattern, and the 'restate your assumption so they can correct course' instruction is repeated three times (Step 1 close, Step 2 intro, and the topic-first paragraph). These are trimmable but a small fraction of a purposeful document.

Actionability

Fully executable guidance for an instruction-only skill: exact tool calls (AskUserQuestion with specified option brackets and density levels), copy-paste snippets (export const meta/design shapes), concrete paths (slides/<id>/index.tsx), a page-role table with id examples, a preview URL, and lockfile-matched dev commands. Nothing remains abstract.

Workflow Clarity

Eight clearly sequenced, headed steps with real checkpoints (Step 3 id-collision check, Step 2 'MUST ask before writing code', Step 7 self-review with a fix loop). It falls short of a 5 because validation detail is delegated to the external slide-authoring checklist and visual verification is conditional ('If the dev server is already running') with no fallback verification step.

Progressive Disclosure

The skill has no bundle files of its own and appropriately splits concerns: the workflow lives here while the technical reference is delegated one level deep to the slide-authoring skill via clearly signaled, named sections ('Self-review before finishing', 'Image placeholders', 'Speaker notes', 'Design system'). Step headers make navigation easy and nothing is inlined that belongs elsewhere.

Specificity

The description lists several concrete action phrasings ('create, draft, author, or generate new slides / a presentation', 'a deck with speaker notes / a script', 'add content under slides/') plus a concrete path trigger, with only minor gaps — the verbs are largely synonyms of one core capability rather than multiple distinct actions.

Completeness

It explicitly answers both what ('create, draft, author, or generate new slides / a presentation in this open-slide repo') and when ('Use this skill when...', with concrete trigger phrases), and adds a negative boundary ('Do NOT use for editing the framework itself'). This matches the anchor-5 example structure exactly.

Trigger Term Quality

It quotes six natural user phrases ('make slides about X', 'make a deck about X', 'create a presentation', 'draft slides for', 'new slide') covering the slides/deck/presentation synonyms plus the concrete `slides/` path trigger. File extensions don't apply to this repo-internal format, so coverage is comprehensive.

Distinctiveness Conflict Risk

It carves out a clear niche (authoring new content under `slides/<id>/` in this specific repo) and explicitly excludes framework editing ('Do NOT use for editing the framework itself — only for authoring content inside slides/<id>/'), leaving minimal conflict risk with related skills.
