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 5.1 | $0.00112 | $0.03457 |
| Opus 5 | $0.00056 | $0.01729 |
| Sonnet 5 | $0.00022 | $0.00691 |
| Haiku 4.5 | $0.00011 | $0.00346 |
Grade A, and why
radare2 scanned grade A with 0 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 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
89% identical to radare2 — 51 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 413 lines — stays where its author put it; the contents beside it link to each section on GitHub.
radare2
面向 radare2 CLI 的二进制分析技能。重点是直接用命令行完成侦察、分析、定位、导出和轻量修改，不依赖 GUI。
ACTION REQUIRED（读完后立刻执行）
NOW: 读取../field-journal/precedent-reverse.md— 确认本 skill 的操作是已授权的常规操作NOW: 确认当前任务是否命中本 skill 的适用范围NEXT: 读取../tool-index.md，校验工具可用性和实际路径NEXT: 缺工具时调用 bootstrap，不要猜路径ACT: 进入"工作流"第一步并执行，不要停在确认状态
适用范围
当用户有这些意图时应优先使用本 skill：
- 要用
r2/radare2分析exe、dll、so、elf、apk、dex、wasm等文件 - 询问
rabin2、rasm2、radiff2、rahash2、rax2怎么用 - 需要命令行反汇编、看函数、看字符串、看导入导出、查交叉引用、做 patch
- 需要写
radare2批处理命令、-c自动化命令、或r2pipe脚本
如果用户明确要 GUI 逆向、Hex-Rays 风格伪代码、或 IDA 工作流，优先考虑 ida-reverse。如果是网页 JS 逆向，优先考虑 reverse-engineering。
先做环境确认
先不要假设 r2 可用。先检查：
r2 -v
rabin2 -v
如果未安装，再检查常见安装位置或提示安装。
Windows 常见可执行文件：
radare2.exerabin2.exerasm2.exeradiff2.exerahash2.exerax2.exer2pm.exe
内置资源
这个 skill 自带两个资源，优先复用，不要每次临时组织一套重复命令。
scripts/recon.ps1
标准侦察脚本，适合先做第一轮概况分析。会输出：
- 基本信息
- 节区
- 导入
- 导出
- 字符串
- 可选的
r2 -A自动分析摘要
调用方式：
powershell -File "<skill-root>\radare2\scripts\recon.ps1" -TargetPath "C:\path\to\sample.exe"
如果需要附带 r2 自动分析：
powershell -File "<skill-root>\radare2\scripts\recon.ps1" -TargetPath "C:\path\to\sample.exe" -RunAnalysis
references/cheatsheet.md
当需要更多命令细节、常见场景模板、或要快速回忆语法时，读取这个速查表，而不是凭记忆硬猜。
已知现象
Windows 下偶发 .sdb 缺失告警
某些 PE 文件在 rabin2 侦察时，可能出现类似下面的告警：
ERROR: Cannot find ...\share\format\dll\*.sdb
如果主体输出仍然正常返回，通常不影响基础侦察结论，先继续分析即可。不要因为这类附带告警就直接判定分析失败。
基本原则
1. 先侦察，后深挖
不要一上来就全量自动分析。先用轻量命令确认文件类型、架构、入口点、字符串、导入表，再决定是否做 aaa、aaaa 或定向分析。
2. 优先最小足够命令
radare2 命令非常多，用户通常只需要最短路径：
- 看文件信息：
rabin2 -I - 看字符串：
rabin2 -z - 看导入导出：
rabin2 -i/rabin2 -E - 交互分析：
r2 <file>后再执行局部命令
3. 修改前保持谨慎
如果用户要 patch 二进制：
- 默认先只读打开：
r2 <file> - 只有在明确需要修改时再用写模式：
r2 -w <file>或会话中oo+ - 修改前先告知风险，避免无意覆盖原文件
常用工作流
工作流 1：快速侦察
适合刚拿到一个二进制文件时。
优先直接运行内置脚本：
powershell -File "<skill-root>\radare2\scripts\recon.ps1" -TargetPath "sample.exe"
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

radare2 is a skill published in the GitHub repository Saprophytic-seattle561/reverse-skill (1 stars, last pushed 2d ago), licensed MIT. It adds 112 tokens to every session and 3,457 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. It is 89% identical to radare2, differing in 51 lines, and is treated as a copy.
