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 | $0.00196 | $0.07966 |
| Opus 5 | $0.00098 | $0.03983 |
| Sonnet 5 | $0.00039 | $0.01593 |
| Haiku 4.5 | $0.00020 | $0.00797 |
Grade A, and why
android-reverse-engineering scanned grade A with 2 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 2d 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.
Asks for rootlowPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
- Installs without sudo when possible (downloads to `~/.local/share/`, symlinks in `~/.local/bin/`) Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 570 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Android Reverse Engineering
Decompile Android APK, XAPK, AAB, DEX, JAR, and AAR files using jadx and Fernflower/Vineflower, trace call flows through application code and libraries, analyze security patterns, produce structured documentation of extracted APIs, and perform adaptive dynamic analysis with Frida — generating custom bypass scripts based on what the static analysis finds, iterating through crash logs to refine hooks until protections are bypassed. Two decompiler engines are supported — jadx for broad Android coverage and Fernflower for higher-quality output on complex Java code — and can be used together for comparison.
Prerequisites
This skill requires Java JDK 17+ and jadx to be installed. Fernflower/Vineflower and dex2jar are optional but recommended for better decompilation quality. bundletool is required for AAB (App Bundle) files. For dynamic analysis (Phase 7), Python 3.8+, adb, and a device/emulator with frida-server are needed — the setup-frida.sh script handles the full setup. Run the dependency checker to verify:
bash ${CLAUDE_PLUGIN_ROOT}/skills/android-reverse-engineering/scripts/check-deps.sh
If anything is missing, follow the installation instructions in ${CLAUDE_PLUGIN_ROOT}/skills/android-reverse-engineering/references/setup-guide.md.
Workflow
Phase 1: Verify and Install Dependencies
Before decompiling, confirm that the required tools are available — and install any that are missing.
Action: Run the dependency check script.
bash ${CLAUDE_PLUGIN_ROOT}/skills/android-reverse-engineering/scripts/check-deps.sh
The output contains machine-readable lines:
INSTALL_REQUIRED:<dep>— must be installed before proceedingINSTALL_OPTIONAL:<dep>— recommended but not blocking
If required dependencies are missing (exit code 1), install them automatically:
bash ${CLAUDE_PLUGIN_ROOT}/skills/android-reverse-engineering/scripts/install-dep.sh <dep>

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.

android-reverse-engineering is a skill published in the GitHub repository incogbyte/android-reverse-engineering-claude-skill (109 stars, last pushed 2mo ago), licensed Unlicense. It adds 196 tokens to every session and 7,966 once invoked, about $0.0010 per session on Opus 5. A static security scan graded it A with 2 findings (asks for root, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
