Anything Analyzer is a protocol-analysis toolkit that captures traffic from browsers, desktop and terminal programs, scripts, mobile devices, and other equipment, then uses AI to analyze the resulting requests. It combines browser capture, MITM proxying, JavaScript hooks, fingerprint spoofing, and MCP integration so AI agents and IDEs can inspect APIs, encryption, security issues, and service calls. The catalogue skills expose these capture and analysis workflows to agent tools.
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 | $0.00030 | $0.01140 |
| Opus 5.5 | $0.00012 | $0.00456 |
| Sonnet 5.5 | $0.00006 | $0.00228 |
| Haiku 4.5 | $0.00003 | $0.00114 |
Grade A, and why
protocol-reverse 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 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.
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
100% identical to protocol-reverse — 0 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.

Protocol Reverse Engineering
ACTION REQUIRED（读完后立刻执行）
NOW: 读取../field-journal/precedent-reverse.md— 确认授权与常规操作边界NOW: 确认任务是否为协议/流量/序列化格式逆向（非纯 Web 参数签名 → 转js-reverse/）NOW: 若有目标网络交互 →../scripts/case-init.ps1完成 scope；auth未 granted 禁止对目标 ACTNEXT: 读取../tool-index.md；缺工具 bootstrap（tshark/wireshark 等可能需手动）ACT: 进入工作流 Phase 1，产出帧布局或消息字典草稿
适用场景
- 自定义 TCP/UDP 二进制协议
- Protobuf / gRPC / FlatBuffers / MessagePack
- WebSocket / MQTT / 私有 RPC
- PCAP / PCAPNG 还原字段与状态机
- 客户端-服务端校验、序列号、加密帧头
不走本 skill
| 情况 | 去哪 |
|---|---|
| 仅 HTTP 参数签名 / JS 加密 | js-reverse/ |
| 仅 TLS 证书问题 | pentest-tools/ 或浏览器代理 |
| 固件内协议栈深挖 + 仿真 | firmware-pentest/ 后再回本 skill |
工作流
Phase 1 — 采集与分诊
□ 拿到样本：PCAP / 代理导出 / 客户端日志 / 二进制
□ 标记方向：C→S / S→C；是否有握手、心跳、重连
□ 固定头？魔数？长度字段？TLV？定长？
□ 是否压缩（zlib/gzip/lz4）或加密（AES/ChaCha 帧内）
□ tshark -r cap.pcap -T fields -e frame.number -e ip.src -e tcp.payload
Phase 2 — 帧布局还原
□ 对齐多个同类消息，找不变字节 / 自增序列号
□ 长度字段：大端/小端、含头/不含头
□ 校验：CRC16/32、checksum、HMAC 位置
□ 画出状态机：Connect → Auth → Ready → Request/Response → Close
□ 工具：Wireshark 自定义 dissector 草稿 / ImHex / 010 Editor 模板 / Kaitai Struct
Phase 3 — 序列化与加密
□ Protobuf：.proto 恢复（blackboxprotobuf / pbtk / protoc --decode_raw）
□ gRPC：HTTP/2 headers + protobuf body
□ 加密：找密钥派生（客户端 so/dll/JS）→ 联合 ida-reverse / js-reverse / apk-reverse
□ 重放：仅在授权 scope 内；先无害字段再敏感操作
Phase 4 — 产物
MUST 产出：
- 消息类型表（name / opcode / fields）
- 至少 1 条可复现的解码命令或脚本
- Evidence：原始 hex 摘录 + 解码结果（脱敏）
工具链
| 工具 | 必需 | 用途 | 自举 |
|---|---|---|---|
| tshark / Wireshark | 强烈建议 | PCAP 解析 | 手动 / winget |
| Python3 | 是 | 解码脚本 | 系统 |
| blackboxprotobuf | 可选 | 未知 protobuf | pip |
| ImHex / 010 | 可选 | 结构模板 | 手动 |
| IDA / r2 / Ghidra | 按需 | 客户端序列化函数 | 见对应 skill |

What ships with it
1 file 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.

protocol-reverse is a skill published in the GitHub repository Mouseww/anything-analyzer (3,775 stars, last pushed 10d ago), licensed Apache-2.0. It adds 30 tokens to every session and 1,140 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to protocol-reverse, differing in 0 lines, and is treated as a copy.
