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 | $0.00087 | $0.03223 |
| Opus 5 | $0.00044 | $0.01612 |
| Sonnet 5 | $0.00017 | $0.00645 |
| Haiku 4.5 | $0.00009 | $0.00322 |
Grade A, and why
android-pentest 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 9d 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 — 219 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Android Mobile Application Penetration Testing
Thin router for full MASTG-aligned Android assessments via ADB + Frida + Mobile MCP. Load workflow / methodology / reference files on demand; do not attempt to memorise the whole skill up front.
When to Use
- Start a new Android app security assessment
- Bypass SSL pinning, root detection, anti-tamper, or biometric checks
- Extract/triage local storage (SharedPreferences, DBs, files, logs)
- Test exported activities, services, providers, receivers, deep links
- Hook crypto / auth / session / keystore at runtime
- Map a build to OWASP MASVS / MASTG for compliance evidence
- Produce structured findings + remediation guidance
Trigger Phrases
"pentest this Android app" • "security test the APK" • "bypass SSL pinning on " • "extract data from " • "test Android authentication" • "fuzz Android intents" • "MASTG testing for " • "mobile app security assessment"
When NOT to Use This Skill
- iOS apps → use
ios-pentest(if available) or generic mobile skill - Server-side API fuzzing of mobile backends → use
api-security/web-pentest - Decompiling Android malware for IR → use
malware-analysis, not this pentest-focused skill - Supply-chain / SCA on third-party SDKs → use
sca/dependency-audit - Cloud backend of the mobile app → use
cloud-pentest
Decision Tree
Do you have the APK or only package name?
├─ package only → get_app_info + pull_apk (parallel), then branch on protections
└─ APK on disk → static analysis first (jadx, apktool), then dynamic
└─ App runs? → frida_spawn → bypass_ssl → bypass_root → proxy
└─ App crashes on root? → see references/troubleshooting.md (Root detection)
└─ TLS still not decrypted? → workflows/ssl_pinning_bypass.md Methods 2→3
What's the objective?
├─ Full assessment → workflows/complete_assessment.md
├─ SSL pinning only → workflows/ssl_pinning_bypass.md
├─ Auth / session → workflows/auth_testing.md
├─ Deep links / IPC / fuzz → workflows/deeplink_intent_testing.md
├─ Crypto audit → workflows/crypto_analysis.md
└─ Data storage / exfil → workflows/data_exfiltration.md
What ships with it
60 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
- 9d ago First seen · 219 lines · 87 tokens per session scan A ab14d2aa539f
android-pentest is a skill published in the GitHub repository JustineDevs/premortem (2 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 87 tokens to every session and 3,223 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 2026-09-03.
