hardware-design

hardware-design is an agent for Claude Code from creativec09/stm32. It costs 28 tokens per session (4,376 once invoked), scanned A, original, MIT.

An STM32 electronics and circuit-design specialist covering schematics, printed circuit boards, power supplies, clocks, signals, connectors, and heat management. EMC means reducing unwanted electromagnetic interference so equipment works reliably and meets applicable requirements.

In plain words
What is it for?
Use it to review circuits and board layouts, choose oscillators and components, design power and protection circuits, route fast signals, and address EMC, static discharge, and thermal concerns.
Why use it?
It helps find hardware design problems before they cause unstable operation, interference, overheating, or manufacturing issues.

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

hardware-design 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 1mo 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.

hardware-design is an agent published in the GitHub repository creativec09/stm32 (11 stars, last pushed 7mo ago), licensed MIT. It adds 28 tokens to every session and 4,376 once invoked, about $0.0001 per session on Opus 5.5. 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.
