Re Android Crypto is an agent skill from dslsdzc/rev-skills. Android 加密体系审计(crypto audit):AndroidKeyStore 密钥体系分析(别名/算法/用途/硬件背书)、 Cipher/KeyInfo 审计、加密调用点 hook(Frida 拦截密钥别名与用途)。 触发词:Keystore、AndroidKeyStore、Cipher、KeyInfo、StrongBox、加密审计、crypto hook、密钥别名。
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Security, covering Mobile application security. It works with Android, Frida and Python. The repository describes itself as: 122 个逆向工程 AI 技能(可发布、跨平台):恶意软件分析 / 软件逆向 / 固件嵌入式 / 协议逆向 / 移动应用 / 脱壳反混淆 / 软件破解 / 漏洞挖掘 / 托管代码 / 取证情报 / CTF。 The licence is Apache-2.0.
4 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit bd21db8. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Shell commands in SKILL.md call:
adbFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Re Android Crypto loads about 1.1k tokens when it runs. Until then it costs about 52 tokens; SKILL.md has 234 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Android 加密体系审计(crypto audit):AndroidKeyStore 密钥体系分析(别名/算法/用途/硬件背书)、 Cipher/KeyInfo 审计、加密调用点 hook(Frida 拦截密钥别名与用途)。. Re Android Crypto is an agent skill from dslsdzc/rev-skills.
Re Android Crypto fits situations like: tasks that involve Mobile application security.
Run `npx skills add dslsdzc/rev-skills --skill re-android-crypto -a claude-code`. Or copy the skill folder (.claude/skills/re-android-crypto in dslsdzc/rev-skills) into .claude/skills/re-android-crypto in your project. Claude Code loads it when a task matches its description.
Run `npx skills add dslsdzc/rev-skills --skill re-android-crypto -a codex`. Or copy the skill folder (.claude/skills/re-android-crypto in dslsdzc/rev-skills) into .agents/skills/re-android-crypto in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add dslsdzc/rev-skills --skill re-android-crypto -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/re-android-crypto, .gemini/skills/re-android-crypto, .github/skills/re-android-crypto and .opencode/skills/re-android-crypto in your project.
Going by SKILL.md and its folder, Re Android Crypto needs the command-line tools its instructions call (adb). Our summary lists: Python 3.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Re Android Crypto is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.1k tokens (SKILL.md is roughly 4.5k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
