zephyr-custom-driver

zephyr-custom-driver is a skill for Claude Code, Codex from Jayant-Tang/nrf-connect-skills-ZH_CN. It costs 116 tokens per session (1,819 once invoked), scanned A, original, no licence file.

Instructions for adding a custom hardware driver to a Zephyr or NCS embedded application. A driver is code that lets software communicate with hardware such as a sensor or display.

In plain words
What is it for?
Creating out-of-tree modules, device-tree bindings, CMake and Kconfig files, subsystem APIs, and the configuration needed to load sensor, display, SPI, I2C, MSPI, or GPIO drivers.
Why use it?
They explain the project files and settings needed for Zephyr to discover, configure, and build an external driver.

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-custom-driver 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 2mo 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.
