Conciseness

Almost everything is non-obvious project-specific contract knowledge (no explaining of concepts Claude already knows), but presentation could be tightened considerably: step 1's options paragraph alone runs ~400 words covering `cacheHasData`, `revalidateCachedHasData`, `recheckActionTypes`, and `allowReturnToSetup` in one unbroken block, and the keyed-by-mode rationale for `wizard`/`primaryAction` digresses into multiple per-product examples inline. This fits "mostly efficient but could be tightened" better than "minor instances that could be trimmed".

Actionability

Fully executable guidance throughout: a copy-adaptable `createSetupDetectionLogic` snippet, the bespoke-logic `connect`/listener push pattern, the `SceneExport` declaration block, exact file paths for every reference adoption, and runnable commands (`pnpm build:products`, `pnpm --filter=@posthog/frontend typescript:check`, the `?empty_state=1` QA param).

Workflow Clarity

A clearly sequenced adoption workflow (steps 1, 2, 3, 4, 4b, 5, 6) with explicit validation checkpoints: a test step asserting `productSetupStatusLogic(...).values.status`, storybook visual-regression coverage, and a closing QA checklist (dark mode, reduced motion, self-hosted, skip persistence, "Loading never flashes", "Non-adopting scenes unaffected", typecheck + stable snapshots).

Progressive Disclosure

Good structure with clear section headers, and references are one level deep and well signaled — every pointer ("Reference: `products/mcp_analytics/frontend/emptyState/mcpAnalyticsEmptyState.tsx`", "References: `MCPToolCallPreview.tsx`, `FeatureFlagPreview.tsx`", "see `types.ts` for every field") targets real files in the target repo, verified as plausible in-repo paths (no bundle files exist in this skill). Not a 5 because substantial sub-topics (the step 3 preview-widget design rules, the step 1 detection options) are inlined in a single ~135-line file where a reference file could carry the detail.

Specificity

Multiple concrete actions are enumerated: "adding an empty state or first-run/setup screen to a product scene, declaring `emptyState` on a `SceneExport`, writing a product setup-status detection logic, building an animated example-data preview widget, or deciding between the scene-level `ProductEmptyState` gate and an inline `ProductIntroduction` panel" — comprehensive coverage of the skill's capabilities with no vague filler.

Completeness

The "what" is explicit ("Guide for adding a product setup empty state — the skippable first-run screen a product scene shows until real data arrives, built on the shared ProductEmptyState component") and the "when" is an explicit "Use when..." clause with five concrete trigger phrases. Not the level below (4) because the when-clause is specific and multi-trigger rather than merely present.

Trigger Term Quality

Good natural keyword coverage ("empty state", "first-run", "setup screen", "product scene") plus specific API terms a developer would name ("SceneExport", "detection logic", "preview widget"). A few common synonyms a user might naturally say are missing (e.g. "zero state", "no data screen", "onboarding screen"), keeping it just below comprehensive.

Distinctiveness Conflict Risk

A clear niche (product setup empty states on a specific component) with distinct triggers, and it even disambiguates against the nearest neighbor inline panel ("deciding between the scene-level `ProductEmptyState` gate and an inline `ProductIntroduction` panel"), minimizing risk of triggering for the wrong skill.
