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 | $0.00176 | $0.03479 |
| Opus 5 | $0.00088 | $0.01740 |
| Sonnet 5 | $0.00035 | $0.00696 |
| Haiku 4.5 | $0.00018 | $0.00348 |
Grade A, and why
jlink 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 3d 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.
How it starts
The opening of the file, as written. The whole thing — 287 lines — stays where its author put it; the contents beside it link to each section on GitHub.
J-Link 下载与在线调试
本 skill 提供 J-Link 探针的设备探测、固件烧录、内存读写、寄存器查看、目标复位、RTT 日志读取，以及轻量在线调试和 GDB 源码级调试能力。
配置
环境级配置（skill/config.json）
skill 目录下的 config.json 包含环境级配置（工具路径、端口号等），首次使用前确认 exe 路径正确：
{
"exe": "C:\\Program Files\\SEGGER\\JLink\\JLink.exe",
"gdbserver_exe": "C:\\Program Files\\SEGGER\\JLink\\JLinkGDBServerCL.exe",
"rtt_exe": "C:\\Program Files\\SEGGER\\JLink\\JLinkRTTClient.exe",
"gdb_exe": "C:\\Program Files\\Arm\\GNU Toolchain mingw-w64-x86_64-arm-none-eabi\\bin\\arm-none-eabi-gdb.exe",
"serial_no": "",
"rtt_telnet_port": 0,
"swo_command": [],
"operation_mode": 1
}
exe：JLink.exe 完整路径（必填）gdbserver_exe：JLinkGDBServerCL.exe 路径，RTT 和 GDB 调试需要rtt_exe：JLinkRTTClient.exe 路径gdb_exe：arm-none-eabi-gdb 路径，GDB 源码级调试需要serial_no：默认探针序列号，多探针场景下使用rtt_telnet_port：RTT 端口，0 表示使用工具默认值swo_command：可选，完整 SWO viewer 命令数组，供jlink_swo.py包装operation_mode：1直接执行 /2输出风险摘要但不阻塞 /3执行前确认
工程级配置（.embeddedskills/config.json）
设备参数（device/interface/speed）统一在工作区的 .embeddedskills/config.json 中管理：
{
"jlink": {
"device": "STM32F407VG",
"interface": "SWD",
"speed": "4000"
}
}
device：芯片型号（如 STM32F407VG、GD32F470ZG）interface：调试接口，SWD 或 JTAG，默认 SWDspeed：调试速率 kHz，默认 4000
参数解析优先级：CLI 显式参数 > .embeddedskills/config.json（工程级）> skill/config.json（环境级）> .embeddedskills/state.json > 默认值/报错
成功执行后，确认过的 device/interface/speed 会自动写回工程配置。

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.
- 3d ago First seen · 287 lines · 176 tokens per session scan A 3208ac2f971b
jlink is a skill published in the GitHub repository zhinkgit/embeddedskills (610 stars, last pushed 13d ago), licensed MIT. It adds 176 tokens to every session and 3,479 once invoked, about $0.0009 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
