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 | $0.00051 | $0.04668 |
| Opus 5 | $0.00026 | $0.02334 |
| Sonnet 5 | $0.00010 | $0.00934 |
| Haiku 4.5 | $0.00005 | $0.00467 |
Grade A, and why
jadx 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 5d 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.

Jadx - Android APK Decompiler
You are helping the user decompile Android APK files using jadx to convert DEX bytecode into readable Java source code for security analysis, vulnerability discovery, and understanding app internals.
Tool Overview
Jadx is a dex to Java decompiler that produces clean, readable Java source code from Android APK files. Unlike apktool (which produces smali), jadx generates actual Java code that's much easier to read and analyze. It's essential for:
- Converting DEX bytecode to readable Java source
- Understanding app logic and control flow
- Finding security vulnerabilities in code
- Discovering hardcoded credentials, API keys, URLs
- Analyzing encryption/authentication implementations
- Searching through code with familiar Java syntax
Prerequisites
- jadx (and optionally jadx-gui) must be installed
- Java Runtime Environment (JRE) required
- Sufficient disk space (decompiled output is typically 3-10x APK size)
- Write permissions in output directory
GUI vs CLI
Jadx provides two interfaces:
CLI (jadx): Command-line interface
- Best for automation and scripting
- Batch processing multiple APKs
- Integration with other tools
- Headless server environments
GUI (jadx-gui): Graphical interface
- Interactive code browsing
- Built-in search functionality
- Cross-references and navigation
- Easier for manual analysis
- Syntax highlighting
When to use each:
- Use CLI for automated analysis, scripting, CI/CD pipelines
- Use GUI for interactive exploration and deep-dive analysis
Instructions
1. Basic APK Decompilation (Most Common)
Standard decompile command:
jadx <apk-file> -d <output-directory>
Example:
jadx app.apk -d app-decompiled
With deobfuscation (recommended for obfuscated apps):
jadx --deobf app.apk -d app-decompiled
2. Understanding Output Structure
After decompilation, the output directory contains:
app-decompiled/
├── sources/ # Java source code
│ └── com/company/app/ # Package structure
│ ├── MainActivity.java
│ ├── utils/
│ ├── network/
│ └── ...
└── resources/ # Decoded resources
├── AndroidManifest.xml # Readable manifest
├── res/ # Resources
│ ├── layout/ # XML layouts
│ ├── values/ # Strings, colors
│ ├── drawable/ # Images
│ └── ...
└── assets/ # App assets
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.
- 5d ago First seen · 663 lines · 51 tokens per session scan A c26ec3f58de5
jadx is a skill published in the GitHub repository BrownFineSecurity/iothackbot (825 stars, last pushed 3mo ago), licensed MIT. It adds 51 tokens to every session and 4,668 once invoked, about $0.0003 per session on Opus 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.
