An Android reverse-engineering command that decompiles application and library files such as APKs, XAPKs, AABs, DEX files, JARs, and AARs, then examines their structure.

Use it to inspect Android packages, identify their contents, and begin tracing code and APIs during application analysis.

It gives you a starting view of how a compiled Android application is organised when its original source code is unavailable.

Getting it into your agent

Token cost

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	$0.00019	$0.01061
Opus 5	$0.00010	$0.00531
Sonnet 5	$0.00004	$0.00212
Haiku 4.5	$0.00002	$0.00106

Security

Grade B, and why

decompile scanned grade B 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 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 rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

The install script auto-detects the OS and installs without sudo when possible (user-local install to `~/.local/`). If sudo is needed, it will prompt — if the user declines or sudo is unavailable, the script prints exact

The opening of the file, as written. The whole thing — 96 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/decompile

Decompile an Android application and perform initial structure analysis.

Instructions

You are starting the Android reverse engineering workflow. Follow these steps:

Step 1: Get the target file

If the user provided a file path as an argument, use that. Otherwise, ask the user for the path to the APK, XAPK, AAB, DEX, JAR, or AAR file they want to decompile.

Step 2: Check and install dependencies

Run the dependency check:

bash ${CLAUDE_PLUGIN_ROOT}/skills/android-reverse-engineering/scripts/check-deps.sh

Parse the output looking for INSTALL_REQUIRED: and INSTALL_OPTIONAL: lines.

If required dependencies are missing, install them one by one:

bash ${CLAUDE_PLUGIN_ROOT}/skills/android-reverse-engineering/scripts/install-dep.sh java
bash ${CLAUDE_PLUGIN_ROOT}/skills/android-reverse-engineering/scripts/install-dep.sh jadx

The install script auto-detects the OS and installs without sudo when possible (user-local install to ~/.local/). If sudo is needed, it will prompt — if the user declines or sudo is unavailable, the script prints exact manual instructions (exit code 2). Show those instructions to the user and stop.

For optional dependencies (INSTALL_OPTIONAL:vineflower, INSTALL_OPTIONAL:dex2jar, INSTALL_OPTIONAL:bundletool, etc.), ask the user if they want to install them. Recommend vineflower and dex2jar for better results. bundletool is required for AAB files.

After any installations, re-run check-deps.sh to verify. Do not proceed until all required dependencies pass.

Step 3: Decompile

Run the decompile script on the target file. Choose the engine based on the input:

APK, XAPK, or AAB → use jadx first (handles resources natively; XAPK is auto-extracted; AAB uses bundletool):
```
bash ${CLAUDE_PLUGIN_ROOT}/skills/android-reverse-engineering/scripts/decompile.sh <file>
```

DEX → jadx handles DEX natively:

bash ${CLAUDE_PLUGIN_ROOT}/skills/android-reverse-engineering/scripts/decompile.sh <file>

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.

decompile is a command published in the GitHub repository incogbyte/android-reverse-engineering-claude-skill (109 stars, last pushed 2mo ago), licensed Unlicense. It adds 19 tokens to every session and 1,061 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
