VRC Check Skill

Help developers prepare and validate Meta Quest apps for store submission. This skill covers the full publishing readiness lifecycle -- project configuration, code review, VRC compliance, content policies, data use, and store assets.

When to Use

• Preparing an app build for Meta Quest Store submission
• Reviewing project config, manifest, or permissions before upload
• Investigating a VRC failure or "Changes Requested" rejection
• Auditing compliance before a new binary upload

Publishing Lifecycle

Apps go through these phases before reaching the store. Understand which phase the developer is in to focus your review.

1. Development -- App ID, Platform SDK, entitlement check, engine config
2. Testing -- Playtest, internal QA, release channel distribution (Alpha/Beta/RC)
3. Pre-submission -- VRC self-check, manifest audit, permissions audit, APK packaging
4. Data Use Checkup -- Required if the app uses platform features (submit before app review)
5. Production upload -- Upload build to the Production channel on the Developer Dashboard
6. Technical review -- Meta verifies VRC requirements
7. Content review -- Meta evaluates UX quality, content guidelines, polish
8. Approval and release -- App goes live on Meta Horizon Store

After release, binary updates ship immediately without review. Metadata updates (descriptions, images, trailers) require 1-2 day review.

Validation Workflow

Work through each step in order. Each step tells you what to check and points to a reference doc when you need deeper detail.

Step 1: Project Configuration

Verify the project is set up correctly for store submission.

Check these items:

• App ID exists on Developer Dashboard and is configured in the engine (not just dashboard-side)
• Meta Platform SDK is installed and initialized at startup
• Entitlement check runs within 10 seconds of launch (VRC.Quest.Security.1 -- most commonly failed VRC)
• On failed entitlement: app exits, shows error, or enters limited demo mode

Find entitlement check in code:

# Unity
grep -rn "Entitlements\|IsEntitled\|GetViewerEntitled\|PlatformInitialize" --include="*.cs" Assets/

# Unreal
grep -rn "Entitlement\|OvrPlatform\|GetViewerEntitlement" --include="*.cpp" --include="*.h" Source/

# Native / Spatial SDK
grep -rn "ovr_Entitlement_GetIsViewerEntitled\|ovr_PlatformInitializeAndroid" --include="*.c" --include="*.cpp" --include="*.h" src/

If entitlement check is missing or deferred, flag it -- this will fail review.

Step 2: Manifest and Permissions

Audit the Android manifest against release requirements. Non-conforming manifests fail VRC.Quest.Packaging.1.

Quick manifest check on a built APK:

aapt dump badging app.apk

Verify: targetSdkVersion is 32-34 for immersive apps (32-36 for 2D panel apps), minSdkVersion 29-32, installLocation is auto, debuggable is false/unset.

Permissions check:

aapt dump permissions app.apk

Cross-reference against three categories: prohibited (auto-reject on upload), review-requiring (need justification), and safe. Unity and Unreal silently add permissions via plugins -- remove them before submission.

For the full manifest spec, SDK version table, prohibited/review-requiring permission lists, and engine-specific removal instructions, see references/publishing-requirements.md.

Step 3: Build and Package

Validate the release APK before upload.

apksigner verify app.apk         # Signature (VRC.Quest.Packaging.2)
ls -lh app.apk                   # Size < 1 GB (VRC.Quest.Packaging.5)
aapt dump badging app.apk | grep native-code  # 64-bit arm64-v8a (VRC.Quest.Packaging.6)

Also verify: keystore is consistent across versions, no unsupported Android features (no Google Play Services), expansion files follow OBB naming and size limits.

For packaging specs and expansion file details, see references/publishing-requirements.md.

Step 4: On-Device Functional and Performance Testing

Deploy to a Quest device and run through the app.

hzdb app install ./app.apk
hzdb app launch com.example.app
hzdb perf capture

Test for at least 45 minutes (or content length, whichever is shorter):

• Framerate stays at target refresh rate (VRC.Quest.Performance.1)
• No thermal throttling prompt (VRC.Quest.Performance.2)
• Head-tracked graphics appear within 4 seconds of launch (VRC.Quest.Performance.3)
• App pauses when HMD removed (VRC.Quest.Functional.2)
• Focus-aware under Universal Menu (VRC.Quest.Input.4)
• Internet-required notification when offline (VRC.Quest.Functional.7)
• No crashes, freezes, or stuck states (VRC.Quest.Functional.1, .3)
• Multi-user support works (VRC.Quest.Functional.12)

For the complete VRC test plan with all categories and test steps, see references/vrc-test-plan.md.

Step 5: Content Review Readiness

After technical review passes, Meta evaluates the app's UX quality, content, and policies. Prepare for this by reviewing:

• UX quality -- Locomotion comfort, object interactions, player orientation, camera control
• Depth -- Content variety, replay value, clear game loop / goal-based interactions
• Graphics and audio -- Consistent art, smooth animations, spatial audio, legible UI/text
• Content guidelines -- No policy violations (violence, adult content, unsafe substances)
• App policies -- Payments through Platform IAP only, no unauthorized ads, app sharing support required, IARC content rating obtained

For the full content review criteria, app policies, and brand guidelines, see references/content-and-policies.md.

Step 6: Data Use Checkup

Required if the app uses platform features that access user data.

Features that require a DUC: User ID, User Profile, Avatars, Achievements, In-App Purchases, Matchmaking, Leaderboards, Cloud Storage, Deep Linking, Invites, Followers, Parties, Subscriptions, Challenges, User Age Group.

Verify:

• Which platform features the app uses (search code for Platform SDK API calls)
• Privacy policy URL is live, public, and contains actual policy content
• DUC is submitted before app review (provisional access is revoked during review)
• Annual recertification plan is in place

For the DUC features table, submission process, and data handling questions, see references/content-and-policies.md.

Step 7: Store Metadata and Assets

Review all store-facing materials before submission.

Metadata checklist:

• App name is unique and not keyword-stuffed
• Short and long descriptions meet content guidelines
• Keywords are relevant, no unauthorized IP
• App website and support URLs load correctly
• Privacy policy URL is live and public
• Any Meta/Oculus branding follows brand guidelines

Asset checklist:

• Logo has transparent background
• Cover art is consistent across all variants, title in safe area, no text in bleed zones
• Screenshots are real in-app captures (5 required, no duplicates, no marketing text)
• Trailer is 30s-2min, 16:9, 1080p minimum, no letterboxing, only Quest hardware shown
• Art text uses >= 24pt font

For full asset specifications, safe area rules, and format requirements, see references/store-assets.md.

Step 8: Generate Readiness Report

Summarize findings as a pass/fail checklist:

1. Project config -- App ID, Platform SDK, entitlement check
2. Manifest -- SDK versions, required elements, debug flag
3. Permissions -- No prohibited, review-requiring justified, unnecessary removed
4. Packaging -- Signature, size, 64-bit, expansion files
5. Performance -- Framerate, thermal, load time
6. Functional -- Pause, focus-aware, input, tracking, multi-user, localization
7. Content -- UX quality, guidelines adherence, policies
8. Data Use -- DUC submitted and complete (if applicable)
9. Metadata -- Name, descriptions, keywords, URLs, privacy policy
10. Assets -- Cover art, screenshots, trailer, logo

Flag any failures with VRC IDs and remediation steps. Recommend whether the build is ready for Production channel upload.

Common Pitfalls

The most frequently failed VRCs -- check these first:

hzdb Quick Reference

hzdb (Horizon Debug Bridge) is the CLI for on-device testing. Install once:

npm install -g @meta-quest/hzdb

hzdb device list                              # Verify device connection
hzdb device battery                           # Check battery and thermal state
hzdb app install ./app.apk                    # Deploy build
hzdb app launch com.example.app               # Launch app
hzdb app stop com.example.app                 # Stop app
hzdb log                                      # View app logs
hzdb adb logcat --tag ThermalService --level W  # Thermal monitoring
hzdb perf capture                                     # Performance profiling
hzdb capture screenshot                       # Capture VR view
hzdb docs search "entitlement check"          # Search documentation
