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 | $0.00083 | $0.03225 |
| Opus 5 | $0.00042 | $0.01613 |
| Sonnet 5 | $0.00017 | $0.00645 |
| Haiku 4.5 | $0.00008 | $0.00323 |
Grade C, and why
re-mips scanned grade C 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 9d 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.
Reaches for credential fileshighPrivilege escalation
SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.
- **配置与密码哈希提取**：/etc/passwd、/etc/shadow、/etc/config 配置目录（开源路由系统常见）与 web 备份配置；密码哈希常见 `$1$`（MD5-crypt）、`$5$` / `$6$`（SHA-crypt）及自定义格式；备份配置常 base64 / gzip / 自定义打包（衔接 [[re-fw-rootfs]] 与 [[re-crypto-id]]） How it starts

MIPS 架构逆向（路由器固件）
何时使用 / 何时不用
- 用：MIPS 架构 ELF 样本/恶意软件（路由器、嵌入式设备固件中解出的可执行文件）
- 用：路由器固件内程序（web 后端、服务、工具类二进制）的逻辑分析
- 用：MIPS 大端（mips）/小端（mipsel）任意端序的二进制
- 不用：ARM / x86 等其他架构（通用底座 [[re-binary-core]]，本技能只补 MIPS 特有语义）
- 不用：只需解包固件看内容（走 [[re-fw-extract]]）
- 不用：只需分析文件系统/配置（走 [[re-fw-rootfs]]）
- 不用：需要整体运行固件（走 [[re-fw-emulate]]）
工具准备
所有工具先验证再使用。静态分析可免沙箱；qemu-user 动态执行默认沙箱 + 网络隔离（[[platform-tips]] 最高原则）。
反编译器（Ghidra / IDA 任选其一）
- Ghidra（内置 MIPS 处理器模块，mips / mipsel / mips64 / mips64el 变体齐全）：
- Linux: 官方 release 包（需 JDK）；部分发行版仓库有
apt install ghidra/pacman -S ghidra - macOS:
brew install --cask ghidra；Windows: 官方 zip - 验证:
analyzeHeadless -help（headless 模式）或 GUI 导入 MIPS ELF
- Linux: 官方 release 包（需 JDK）；部分发行版仓库有
- IDA：商业版含 MIPS 模块；Freeware 版架构支持范围以官方页面为准
- 导入时确认处理器变体与端序正确（mips 大端 / mipsel 小端），选错全部错位
binwalk / unblob —— 固件与内嵌文件扫描
- 同 [[re-fw-extract]] 工具准备：
pip install binwalk（推荐）或发行版包；unblob:pip install unblob - 验证:
binwalk --version、unblob --version
readelf / file —— 架构与字节序确认（binutils）
- Linux: binutils 自带（
apt install binutils等）；macOS:brew install binutils或 LLVM 系 readelf；Windows: WSL 内 - 验证:
readelf --version
qemu-user —— MIPS 用户态仿真（动态验证）
- Linux:
apt install qemu-user/dnf install qemu-user/pacman -S qemu-user - macOS:
brew install qemu（含用户态）；Windows/WSL: WSL 内 Linux 版 - 大小端是独立二进制：
qemu-mips（大端）/qemu-mipsel（小端），64 位为qemu-mips64/qemu-mips64el - 验证:
qemu-mips --version、qemu-mipsel --version
python3
- Linux:
apt install python3/dnf install python3/pacman -S python - macOS: 自带；Windows: 官方安装器
- 验证:
python3 --version
操作步骤
按顺序执行，每步结果存档；步骤 5（动态执行）默认沙箱。
- 前置：固件提取与架构确认：
- 固件整体文件 → [[re-fw-extract]] 解包；解出的文件系统 → [[re-fw-rootfs]]；解出的 ELF 继续本步骤
- 架构确认：
file target.elf # 是否 MIPS + 端序提示 readelf -h target.elf # Machine=MIPS；Data=big-endian/little-endian readelf -A target.elf | head # 子版本/ABI 附加信息 file输出含 "MIPS" 才进入本技能流程；非 MIPS 转 [[re-binary-core]] 通用底座
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.

re-mips is a skill published in the GitHub repository dslsdzc/rev-skills (54 stars, last pushed 14d ago), licensed Apache-2.0. It adds 83 tokens to every session and 3,225 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it C with 1 finding (reaches for credential files). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
