zephyr-serial-log

zephyr-serial-log is a skill for Claude Code, Codex from Jayant-Tang/nrf-connect-skills-ZH_CN. It costs 133 tokens per session (820 once invoked), scanned A, original, no licence file.

A serial-log reader for nRF development boards and other nRF devices. It identifies the correct virtual or regular serial port and captures startup and runtime messages from the device.

In plain words
What is it for?
Use it to check firmware output, capture boot logs, select a COM or VCOM port, handle DTR reset behavior, and investigate missing or corrupted nRF54L15 serial output.
Why use it?
It helps avoid reading the wrong port or missing early boot messages after a device reset, and flags incomplete or garbled output instead of guessing what it says.

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

zephyr-serial-log 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 20d 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 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.
