MobileGuard

AI governance for consumer mobile platforms. Prevents App Store and Google Play rejections caused by AI-generated code.

The Problem

AI coding agents (Claude Code, GitHub Copilot, Cursor, Codex) generate mobile code with zero awareness of mobile governance constraints:

Apple App Store Guideline 5.1.2(i) — AI data disclosure and consent (Nov 2025)
Google Play AI Policy — data safety declarations for AI features
EU AI Act Article 50 — transparency obligations (enforcement: Aug 2, 2026)
Binary immutability — no hotfix without 1–3 day App Store review
Ambient AI boundaries — Siri App Intents, Android AppFunctions permission scopes

72% of AI-generated mobile apps leak secrets. 45% introduce OWASP vulnerabilities. 20 documented incidents exposed tens of millions of users between Jan 2025–Feb 2026. MobileGuard catches these violations before they reach the store.

Install

pip install mobileguard

Requires Python 3.11+. The scan command works offline with no API key. The contract command requires an Anthropic API key.

Quick Start

# Scan your project for governance violations
mobileguard scan ./MyApp

# Generate an EU AI Act compliance report
mobileguard audit ./MyApp --app-name "My App" --version "2.0.0"

# Create a quality contract
mobileguard init --platform ios --bundle-id com.example.myapp

# Evaluate AI-generated code against the contract (requires ANTHROPIC_API_KEY)
mobileguard contract ./GeneratedFeature.swift --stage code-generation --agent claude-code

# Check an AI agent's current autonomy tier
mobileguard tier my-agent-01

What MobileGuard Catches — and Why Existing Tools Don't

MobileGuard is not SwiftLint. It is not a code quality linter. It catches one specific category: governance violations in AI-generated mobile code that no existing tool addresses because no existing tool was designed with mobile deployment constraints in mind.

Tool	What it catches	What MobileGuard adds
GitHub Secret Scanning	Hardcoded secrets in source	AS-001: AI API calls without governance disclosure
Xcode Analyzer	Code quality, API misuse	AS-006: AI calls without privacy manifest entry
SwiftLint	Style, patterns	AS-007: AI-generated code execution in WKWebView
Apple Review	Post-submission gate	PGSG: Pre-submission prediction before binary is immutable
(Nothing)	—	AABE: Maps ambient agent entry points for governance documentation

Three governance layers MobileGuard covers:

Layer 1 — Source governance (v1.0) AI API calls without 5.1.2(i) disclosure, hardcoded keys, prompt injection, PII in requests. What happens in your code.

Layer 2 — Declaration governance (v1.1 — AS-006) AI calls in source not declared in PrivacyInfo.xcprivacy. What your code says versus what your manifest declares. Apple rejects this before human review.

Layer 3 — Architectural governance (v1.1 — AS-007) AI-generated content executed in WKWebView. What your binary does versus what Apple reviewed. Blocked Replit, Vibecode, Anything in 2026.

Layer 4 — Ambient surface governance (v1.1 — mobileguard surface) Every AppIntent and AppFunction an ambient AI agent can trigger. What Siri and Gemini can do in your app that you may not have designed.

Using on a Real Project

1. Scan a repo locally

# Clone any iOS / Android / Flutter app and scan it
git clone https://github.com/some-org/some-app
mobileguard scan ./some-app --platform ios

# Focus on store-blocking issues only
mobileguard scan ./some-app --platform ios --fail-on critical --rules app-store,eu-ai-act

# Export SARIF for the GitHub Security tab
mobileguard scan ./some-app --platform ios --format sarif --output results.sarif

2. Add to the app's CI pipeline

Add this to the app repo's workflow (not MobileGuard's own CI). Pin the version so governance rules don't silently change between runs.

- name: MobileGuard governance scan
  run: |
    pip install mobileguard==1.1.0
    mobileguard scan . --platform ios --fail-on critical --format sarif --output mobileguard.sarif

- name: Upload to GitHub Security tab
  uses: github/codeql-action/upload-sarif@v3
  with:
    sarif_file: mobileguard.sarif

With --fail-on critical, the step exits 1 and blocks the PR if any App Store or EU AI Act critical violation is found. Violations appear inline on the PR diff in the Security tab.

3. Pre-release compliance audit

Run before cutting a release branch to generate the formal document for legal or App Store review:

mobileguard audit ./MyApp \
  --app-name "MyApp" \
  --version "3.2.0" \
  --platform ios \
  --format html \
  --output audit-3.2.0.html

Open audit-3.2.0.html in a browser and use File → Print → Save as PDF to produce the compliance document. (PDF export direct from the CLI is planned for v1.2.)

4. Evaluate AI-generated code against a contract

# One-time setup
mobileguard init --platform ios --bundle-id com.example.myapp
export ANTHROPIC_API_KEY=sk-ant-...

# Run after each AI agent produces code
mobileguard contract ./GeneratedFeature.swift --stage code-review --agent claude-code

Results are appended to an append-only audit log at .mobileguard/audit/. Use mobileguard tier <agent-id> to see how much autonomous authority the agent has earned based on its history of clean evaluation cycles.

TAC-M Autonomy Tiers

Tier	Label	Clean Cycles Required	Max Deployment Reach
L1	Autocomplete only	0	0%
L2	Draft for review	1	100% (human-reviewed)
L3	Conditional autonomous	5	10%
L4	Supervised deployment	10	50%
L5	Full autonomous	20	100%

Privacy

MobileGuard does not collect telemetry, send analytics, or phone home. All analysis is performed locally. The only outbound network calls are to the Anthropic API when --llm is passed to scan, or when running contract. API responses are never logged.

Pillar	Command	Problem Addressed
PDQC — Pre-Deployment Quality Contracting	`mobileguard contract`	Binary immutability (no hotfix without store review)
TAC-M — Tiered Autonomy Calibration	`mobileguard tier`	Consumer-scale blast radius of AI agents
PGSG — Platform Gatekeeper Simulation	`mobileguard scan`	Dual-gatekeeper non-determinism (App Store + Play Store)
AABE — Ambient Agent Boundary Enforcement	`mobileguard scan`	Siri App Intents, Android AppFunctions permission scopes
