Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00090 | $0.02446 |
| Opus 5 | $0.00045 | $0.01223 |
| Sonnet 5 | $0.00018 | $0.00489 |
| Haiku 4.5 | $0.00009 | $0.00245 |
Grade A, and why
mobile-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 6d 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 — 85 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Mobile Security
Scope
End-to-end mobile application VAPT for Android (APK/AAB) and iOS (IPA), aligned to the OWASP MASVS v2.x control groups and the MASTG testing process. Four complementary tiers:
- Static reverse engineering of compiled artifacts — Dart AOT snapshots, Unity IL2CPP, React Native/Hermes bytecode, native ARM64
.so/Mach-O, smali. Recover secrets, endpoints, and the crypto contract without a device. - SAST — manifest /
Info.plist, exported-component & IPC surface, WebView, local storage, cryptographic-primitive weakness, code-signing, and automated baseline (MobSF/apkid/apkleaks) → then manual deep-dive. - Dynamic analysis (DAST) — Frida/objection instrumentation, traffic interception, TLS-pinning bypass across stacks, Keychain/Keystore runtime dumps, IPC probing, and root/jailbreak/anti-tamper defeat for MAS-L2 / MASA scope.
- Privacy — data-collection inventory, tracker/SDK enumeration, PII leakage, declared-vs-actual (Play Data Safety / Apple Privacy Manifest).
Static dump first (faster, no device); dynamic is a first-class phase whenever a control can only be proven at runtime (enforced pinning, Keystore-backed keys, root reaction, IPC guards). Cross-asset stitching, scoring, and reporting are owned by sibling skills — this skill produces MASVS/MASTG-tagged findings and hands them off.
Coverage contract
In a coverage-mode engagement (pentest-engagement mobile mode) completion is code-enforced, not narrative. Two surfaces are gated, and both are mandatory:
| Surface | File | Classes |
|---|---|---|
| The app bundle | recon/inventory/mobile-surface.json |
the 15 MAS-* MASVS classes |
| The backend recovered from the bundle | <apex>-api/recon/inventory/surface.json |
the ordinary OWASP API/web classes |
The second row is where the material risk has historically been. A decompiled bundle hands you the full server contract, and that surface is not browser-reachable — so it is systematically under-tested by everyone, including the app's own developers. Recovering the endpoint inventory and driving it through the API classes is not an optional extra; a bundle that yields zero endpoints is treated as a failed acquisition.

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-security is a skill published in the GitHub repository transilienceai/communitytools (509 stars, last pushed 1mo ago), licensed MIT. It adds 90 tokens to every session and 2,446 once invoked, about $0.0005 per session on Opus 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 2026-08-30.
