Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00133 | $0.01955 |
| Opus 5.5 | $0.00053 | $0.00782 |
| Sonnet 5.5 | $0.00027 | $0.00391 |
| Haiku 4.5 | $0.00013 | $0.00196 |
Grade A, and why
mobile-platform-interaction 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 20d 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 — 152 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Mobile Platform Interaction
What Is Broken and Why
Mobile platforms expose rich IPC mechanisms (Intents, Content Providers, URL schemes, XPC, Pasteboard) that apps use to communicate. Without proper access control, exported components become attack vectors: a malicious app can send crafted Intents to trigger sensitive operations, read Content Provider data without permission, or hijack deep links by registering the same scheme. WebViews with JavaScript enabled and addJavascriptInterface create XSS-to-RCE bridges. Deep link URL parameters injected into WebView navigation or SQL queries without sanitization enable injection attacks within the app.
Key Signals
android:exported="true"on Activity, Service, or BroadcastReceiver withoutandroid:permission- ContentProvider with
android:exported="true"and no read/write permission constraints setJavaScriptEnabled(true)in a WebView that loads remote/user-supplied URLsaddJavascriptInterface(obj, "name")exposing Java objects to WebView JSonReceivedSslError().proceed()(also a network issue, creates XSS delivery path)- Deep link Intent filter

Methodology
Android:

run app.package.attacksurface TARGET_PKG— shows all exposed components - Test exported Activity:
adb shell am start -n TARGET_PKG/.SensitiveActivity - Test exported BroadcastReceiver:
adb shell am broadcast -a com.target.ACTION - Test ContentProvider:
adb shell content query --uri content://TARGET_PKG.provider/users - Review deep link handling: trace

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.

mobile-platform-interaction is a skill published in the GitHub repository SecurityTalent/bugskill-ai (13 stars, last pushed 21d ago), licensed MIT. It adds 133 tokens to every session and 1,955 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-27.
