radio-sdr

radio-sdr is a skill for Claude Code, Codex from Asaiuta/reverse-workbench-skill. It costs 34 tokens per session (416 once invoked), scanned A, a copy of radio-sdr, MIT.

A workflow for authorized research on radio signals outside ordinary Wi-Fi, using software-defined radio (SDR) hardware to receive and analyze wireless transmissions. SDR turns radio signals into data that software can inspect.

In plain words
What is it for?
It helps study remote controls, sensors, aircraft broadcasts, and other RF systems by identifying frequencies and modulation, analyzing recordings, and assessing replay feasibility in a shielded lab.
Why use it?
It helps identify unknown wireless devices and protocols in a controlled environment without assuming the signal format in advance.

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.

Security

Grade A, and why

radio-sdr 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.

What it actually says

RF / SDR Security Research

ACTION REQUIRED(读完后立刻执行)

  1. NOW: 频谱与发射受法律严格管制;仅授权频段/屏蔽室/实验目标
  2. NOW: scope 写明设备、频段、是否允许发射(默认只收)
  3. ACT: 只接收识别 → 解调分析 → 实验室复现评估

适用场景

  • 无线遥控/传感器等非 Wi-Fi RF(授权)
  • ADS-B/遥控等协议研究(合法接收)
  • 与 wifi-wireless 分工:本 skill 偏 SDR 通用 RF;Wi-Fi 攻防走 R29

工作流

□ 法规与许可确认
□ 只收:识别中心频率与调制
□ GNU Radio / URH 分析
□ 重放仅屏蔽室且书面允许
□ 结论侧重:是否可未授权控制 / 加固建议

工具链

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.
