claude-red is a library of structured skills that give Claude specialized offensive-security methods for areas such as web vulnerabilities, shellcode, exploit development, and identity systems. It is intended for authorized red-team work, bug-bounty triage, security research, CTF preparation, and operator training. Its catalogue contains the project's skills for loading these security specializations into Claude.
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.

SkillSpector: 9 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 | $0.00185 | $0.03460 |
| Opus 5.5 | $0.00074 | $0.01384 |
| Sonnet 5.5 | $0.00037 | $0.00692 |
| Haiku 4.5 | $0.00018 | $0.00346 |
Grade A, and why
offensive-mobile scanned grade A with 1 finding 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 1mo 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.

Mobile (Android + iOS) — Offensive Testing Methodology
Quick Workflow
- Static: pull the IPA/APK, decompile, dump resources/strings, identify endpoints
- Dynamic: install on rooted/jailbroken device, hook with Frida, intercept TLS
- Map exported attack surface: deep links, URL schemes, exported components
- Storage / Keystore audit: where do secrets live, what protects them
- API: every backend the app talks to is your scope — test like a web app
Lab Setup
Android
- Rooted device or Genymotion / Android Studio AVD with
userdebugbuild - Magisk for systemless root; LSPosed for hooks; Frida server matching device arch
- Burp / Mitmproxy with system-trusted CA via Magisk module (
MagiskTrustUserCerts)
iOS
- Jailbroken device (palera1n / checkra1n / Dopamine depending on iOS version)
- Frida + Objection + Filza + SSH via USB (iproxy 2222 22)
- Burp CA installed via Settings → General → Device Management → Certificate Trust Settings
Static Analysis
Android
# Decode resources + smali
apktool d app.apk -o app
# Decompile to Java
jadx -d app_src app.apk
# Manifest review
xmllint --format app/AndroidManifest.xml | less
# Look for: android:exported="true", intent-filters, custom permissions, debuggable, allowBackup, networkSecurityConfig
# Secrets and endpoints
grep -rE '(https?://[a-z0-9.-]+|api[_-]?key|secret|token|firebase|amazonaws|appspot)' app_src/
grep -r "Log\.[dwief]" app_src/ # leftover debug logs
# Native libs
file app/lib/*/*.so
# RE in Ghidra/IDA; look for JNI_OnLoad and exported Java_* functions
iOS
# Pull IPA from device
frida-ios-dump -o app.ipa "com.vendor.app"
# Or via App Store via 3rd-party tools (Apple Configurator with paid acct, etc.)
unzip app.ipa
# Decrypt if needed (jailbroken device): bagbak / clutch
bagbak com.vendor.app
# Class dump
class-dump-dyld -H Payload/App.app/App -o headers/
# Or for Swift symbols, use Hopper / IDA
# Strings / endpoints

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.

offensive-mobile is a skill published in the GitHub repository SnailSploit/Claude-Red (7,604 stars, last pushed 7d ago), licensed MIT. It adds 185 tokens to every session and 3,460 once invoked, about $0.0007 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
