Description
PlayIntegrityFork bypass verification and validation for Play Integrity spoofing detection

Scripts

preflight-validation.py

Pre-flight checks for bypass prerequisites and configuration.

# Basic validation
uv run .claude/skills/adb-bypass/scripts/preflight-validation.py

# Specify device
uv run .claude/skills/adb-bypass/scripts/preflight-validation.py --device 127.0.0.1:5555

# Detailed check (verbose output)
uv run .claude/skills/adb-bypass/scripts/preflight-validation.py \
    --device 127.0.0.1:5555 \
    --detailed

# Check specific component
uv run .claude/skills/adb-bypass/scripts/preflight-validation.py \
    --check magisk \
    --check playintegrity \
    --check zygisk

# JSON output
uv run .claude/skills/adb-bypass/scripts/preflight-validation.py --json

Features:

  • Magisk installation verification
  • PlayIntegrityFork module check
  • Zygisk enablement verification
  • Device signature validation
  • Detailed status reporting

Workflows

This skill includes TOON-based workflow definitions for automation.

What is TOON?

TOON (Task-Oriented Orchestration Notation) is a structured workflow definition language that pairs with Markdown documentation. Each workflow consists of:

  • [name].toon - Orchestration logic and execution steps
  • [name].md - Complete documentation and usage guide

This TOON+MD pairing approach is inspired by the BMAD METHOD pattern, adapted to use TOON instead of YAML for better orchestration support.

Available Workflows

Workflow files are located in workflow/ directory:

Example Workflows (adb-bypass):

  • workflow/bypass-validation.toon - Verify PlayIntegrityFork installation and bypass status
  • workflow/detection-check.toon - Check if app detects the bypass
  • workflow/integrity-verification.toon - Validate device signature spoofing

Running a Workflow

Execute any workflow using the ADB workflow orchestrator:

uv run .claude/skills/adb-workflow-orchestrator/scripts/adb-run-workflow.py \
  --workflow .claude/skills/adb-bypass/workflow/bypass-validation.toon \
  --param device="127.0.0.1:5555"

Workflow Documentation

Each workflow includes comprehensive documentation in the corresponding .md file:

  • Purpose and use case
  • Prerequisites and requirements
  • Available parameters
  • Execution phases and steps
  • Success criteria
  • Error handling and recovery
  • Example commands

See the workflow/ directory for complete TOON file definitions and documentation.

Creating New Workflows

To create custom workflows for this skill:

  1. Create a new .toon file in the workflow/ directory
  2. Define phases, steps, and parameters using TOON v4.0 syntax
  3. Create corresponding .md file with comprehensive documentation
  4. Test with the workflow orchestrator

For more information, refer to the TOON specification and the workflow orchestrator documentation.

Usage Patterns

Pattern 1: Pre-Flight Bypass Validation

# Run comprehensive pre-flight checks
uv run .claude/skills/adb-bypass/scripts/preflight-validation.py \
    --device 127.0.0.1:5555 \
    --detailed

# Check returns detailed status:
# - Magisk: installed, version, root status
# - PlayIntegrityFork: installed, version, enabled
# - Zygisk: enabled, subsystem status
# - Device: integrity signature, spoofing status

Pattern 2: Workflow-Based Validation

# Complete validation workflow
uv run .claude/skills/adb-workflow-orchestrator/scripts/adb-run-workflow.py \
    --workflow .claude/skills/adb-bypass/workflow/bypass-validation.toon \
    --param device=127.0.0.1:5555 \
    --verbose

Pattern 3: Integration with App Testing

# 1. Validate bypass is active
uv run .claude/skills/adb-bypass/scripts/preflight-validation.py \
    --device 127.0.0.1:5555

# 2. If validation passes, run app tests
if [ $? -eq 0 ]; then
  uv run .claude/skills/adb-karrot/scripts/adb-karrot-test-login.py \
      --device 127.0.0.1:5555
fi

Integration Points

Depends On:

  • System: adb command-line tool
  • Python: uiautomator2, pyyaml, click

Used By:

  • adb-karrot (for bypass validation before app testing)
  • adb-magisk (for post-installation verification)
  • Custom app automation workflows

Complements:

  • adb-magisk (installs PlayIntegrityFork module)
  • adb-karrot (tests apps after bypass activation)
  • adb-workflow-orchestrator (orchestrates validation flows)

PlayIntegrityFork Bypass Overview

What is PlayIntegrityFork? PlayIntegrityFork is a Magisk module that hooks into Android's Play Integrity API to spoof device integrity and prevent detection of running on emulators or rooted devices.

How It Works:

Google Play Integrity API
  ├─ deviceIntegrity() check
  ├─ serverIntegrity() check
  └─ Error handling

PlayIntegrityFork Hook (via Zygisk)
  └─ Intercepts integrity requests
      └─ Returns spoofed device signature
          └─ App receives valid integrity response

Prerequisites:

  • Magisk installed and functional
  • Zygisk subsystem enabled
  • PlayIntegrityFork module installed
  • Module loaded and active

Validation Checks:

  • Magisk root access confirmed
  • PlayIntegrityFork module installed
  • Zygisk subsystem enabled
  • Device signature successfully spoofed
  • No detection errors in logcat

Troubleshooting

Module Not Loaded

# Check Magisk modules
uv run .claude/skills/adb-magisk/scripts/adb-magisk-launch.py \
    --device 127.0.0.1:5555 \
    --wait-text "PlayIntegrityFork"

# Solution: Ensure Zygisk is enabled and device rebooted

Zygisk Not Enabled

# Enable Zygisk
uv run .claude/skills/adb-magisk/scripts/adb-magisk-enable-zygisk.py \
    --device 127.0.0.1:5555 \
    --auto-reboot

Device Detection Still Occurs

# Check logcat for errors
adb logcat | grep -i "integrity\|playintegrity"

# Common issues:
# - Module needs reboot to activate
# - Zygisk disabled or not loaded
# - Incompatible module version

Architecture

Design Principles:

  • Validation-First: Verify bypass before app testing
  • Comprehensive: Check all bypass components
  • Detailed Reporting: Clear status and error messages
  • Integration-Ready: Works with workflow orchestrator

Validation Sequence:

1. Magisk Root Verification
   └─ Check root access, version

2. Module Installation Check
   └─ PlayIntegrityFork installed?

3. Zygisk Verification
   └─ Subsystem enabled and loaded?

4. Device Signature Check
   └─ Integrity spoofing active?

5. Status Reporting
   └─ Return detailed validation results
