Conciseness

The body assumes Claude's competence (no generic concept explanations, dense tables) but restates routing facts across four overlapping places — the dedicated-helpers table, the Native capability gate table, the Supported capabilities table ("routes internally to add-X" repeated per row), the PDF/pen routing rules, plus Step 3's case statement and Step 2's alias list. Mostly efficient but could be tightened by consolidating these tables, so it fits anchor 3 rather than 4.

Actionability

Fully executable throughout: guard-complete bash (cd -- '<working_dir>' || { echo "BLOCKED…" >&2; exit 1; }), a node -e package.json gate, complete copy-paste TypeScript wrappers (haptics, secureStore), concrete JSX and service upload/download call patterns, and an explicit npx --no-install tsc --noEmit verification. The <capability>/<working_dir> placeholders are justified template conventions.

Workflow Clarity

A clearly sequenced 7-step workflow with explicit validation checkpoints: Step 1 file-existence gate, Step 4 package.json check that stops and prints the error verbatim, and Step 6 type-check with a fix-and-revalidate loop ("Fix only in-scope wrapper-side errors"). BLOCKED/NEEDS_CONTEXT propagation and hard rules make the risky operations well gated.

Progressive Disclosure

External references are clearly signaled and one level deep (${PLUGIN_ROOT}/shared/shared-instructions.md, native-artifact-compatibility.md, nested add-camera/add-pdf-report/… helpers), but the skill ships no bundle files of its own and inlines per-capability detail that would live better in reference files — the ~78-line haptics wrapper, the ~34-line secureStore skeleton, and the picker JSX examples are loaded on every invocation of what is primarily a routing skill.

Specificity

Enumerates a comprehensive set of concrete capabilities ("camera, image picker, barcode/QR scanner, document picker, file picker, secure storage, file system, sharing, haptic feedback, PDF generation/viewing, pen/signature capture, background GPS/geolocation tracking") plus concrete ownership of "routing to internal camera/PDF/pen/geolocation implementation helpers". It stays at 4 rather than 5 because the stated actions are limited to entry-point/routing — it never says what the skill actually produces (typed wrappers under src/native/) — and not 3 because coverage goes well beyond 1-2 actions.

Completeness

The "what" is clear and detailed ("Public entry point for native device capabilities and native controls… in a Power Apps mobile app. Also owns routing to internal… helpers and the guidance boundary between native wrappers and Dataverse File/Image host controls"), but there is no "Use when…" clause or equivalent explicit trigger guidance; the "when" is only weakly implied by the "in a Power Apps mobile app" qualifier, which caps completeness at 3.

Trigger Term Quality

Good natural-term coverage including synonym pairs ("pen/signature capture", "background GPS/geolocation tracking", "barcode/QR scanner"). Not 5 because several natural terms users would say — vibration, photo, gallery, print, biometrics — are absent (the body itself normalizes several of these), and not 3 because the included terms are broad and include synonym variants.

Distinctiveness Conflict Risk

Clear niche with distinct triggers: "Power Apps mobile app", "Dataverse File/Image host controls", "native wrappers" scope it sharply, and the explicit boundary/routing ownership minimizes overlap with sibling skills. Not 4 because the domain qualifiers make conflict with generic camera/file/PDF skills minimal.
