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.

SkillSpector: 6 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00080 | $0.01365 |
| Opus 5 | $0.00040 | $0.00682 |
| Sonnet 5 | $0.00016 | $0.00273 |
| Haiku 4.5 | $0.00008 | $0.00136 |
Grade A, and why
pentest-mobile 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 yesterday.
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 — 153 lines — stays where its author put it; the contents beside it link to each section on GitHub.
pentest-mobile
Mobile app pentest advisory. Note: the mobile skill is for react-native/flutter development; pentest-mobile is for engagement-level mobile security testing.
Triggers
- "Android APK pentest"
- "iOS app security test"
- "Frida hook"
- "cert pinning bypass"
- "MobSF report analysis"
- "MASTG/MASVS check"
OWASP MASVS (Mobile Application Security Verification Standard)
| Category | Scope |
|---|---|
| MASVS-STORAGE | Sensitive data local storage |
| MASVS-CRYPTO | Cryptographic protocol use |
| MASVS-AUTH | Authentication + session |
| MASVS-NETWORK | TLS, cert pinning |
| MASVS-PLATFORM | IPC, deep link, WebView |
| MASVS-CODE | Code quality, anti-tampering |
| MASVS-RESILIENCE | Root/jailbreak detect, RASP |
| MASVS-PRIVACY | PII handling, permissions |
Android Methodology
1. APK extraction: apktool d <app>.apk
2. Static: jadx-gui <app>.apk, MobSF upload
3. Manifest: permission list, exported components
4. Dynamic: emulator + Frida + Burp proxy
5. Storage: /data/data/<pkg>/ dump (rooted device)
6. Network: cert pinning bypass + intercept
7. IPC: exported activity, service, broadcast receiver test
8. WebView: file:// scheme, JavaScriptInterface
Suggested Commands
# QUIET — static analysis
apktool d -o ./app-decompiled <app>.apk
jadx -d ./jadx-out <app>.apk
# MobSF (local, offline)
docker run -it --rm -p 8000:8000 opensecurity/mobile-security-framework-mobsf
# Dynamic: Frida (jailbroken/rooted device)
frida-ps -U # USB device process list
frida -U -l hooks.js -f com.example.app # spawn + hook
# Cert pinning bypass (common script)
# frida-codeshare: 'fdciabdul/Universal-Android-SSL-Pinning-Bypass'
frida --codeshare fdciabdul/universal-android-ssl-pinning-bypass-2 -U -f com.example.app
# Objection (Frida wrapper)
objection -g com.example.app explore
# > android sslpinning disable
# > android root disable
iOS Methodology
1. IPA extract: unzip -d ./ipa-out <app>.ipa
2. Static: class-dump + Hopper / Ghidra
3. Plist: Info.plist permissions, URL schemes
4. Dynamic: jailbroken iPhone + Frida + Burp
5. Storage: /var/mobile/Containers/Data/Application/<uuid>/
6. Network: cert pinning bypass (Frida script)
7. URL scheme: deep link injection test
8. Keychain: keychain dumper
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.

pentest-mobile is a skill published in the GitHub repository fatihkan/badi (7 stars, last pushed 2d ago), licensed MIT. It adds 80 tokens to every session and 1,365 once invoked, about $0.0004 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 2026-09-06.
