android-intent-security

android-intent-security is a skill for Claude Code, Codex from frogobox/frogo-sdk. It costs 53 tokens per session (4,946 once invoked), scanned A, a copy of android-intent-security, Apache-2.0.

Guidance for securing Android components and Intents. An Intent is an Android message used to request an action or pass data between app components or apps.

In plain words
What is it for?
Reviewing AndroidManifest.xml settings and code that handles incoming Intents, including activities, services, receivers, and content providers.
Why use it?
It helps prevent malicious apps from sending crafted messages that expose features, data, or permissions they should not access.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

android-intent-security scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 548 lines — stays where its author put it; the contents beside it link to each section on GitHub.

This skill provides guidelines and patterns to secure Android components (Activities, Services, Broadcast Receivers, Content Providers) and handle Intents safely, preventing privilege escalation and unauthorized access.

Glossary

  • Intent: An asynchronous messaging object used to request an action from another app component.
  • Exported component: A component (android:exported="true") that can be launched by other apps on the device.
  • Sticky intent: A broadcast intent that remains in the system cache after it's sent, allowing any app to retrieve its contents.
  • Signature permission: A permission whose protection level is set to signature, granted only to apps signed with the same developer key.
  • onNewIntent: An activity lifecycle callback invoked when an activity is launched with FLAG_ACTIVITY_SINGLE_TOP and is already running at the top of the history stack.
  • PendingIntent: A token granted to a foreign application (for example, system services) allowing it to execute a predefined Intent with the creator's permissions.
  • Mutable PendingIntent: A PendingIntent whose underlying Intent parameters can be modified by the receiving application.
  • ContentProvider: A component that encapsulates data and provides it to other applications via standard query/insert interfaces.
  • IntentSanitizer: A utility class in AndroidX Core used to build a safe, sanitized copy of an incoming Intent by filtering out unauthorized components, actions, or extras.
  • Intent redirection (forwarding): A vulnerability where an application receives an intent from an untrusted source and uses it to launch a private, non-exported component.

Prerequisites

  • The agent MUST be able to describe the function and security implications of onCreate, onNewIntent, and the singleTop launch mode.
  • The agent MUST be able to declare <activity>, <service>, <receiver>, and <provider> tags in AndroidManifest.xml and define their android:exported and android:permission attributes.
  • The agent MUST be able to implement signature verification checks using PackageManager.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
