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 | $0.00028 | $0.04376 |
| Opus 5 | $0.00014 | $0.02188 |
| Sonnet 5 | $0.00006 | $0.00875 |
| Haiku 4.5 | $0.00003 | $0.00438 |
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 2d 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 — 626 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Hardware Agent
Description
Hardware design and PCB specialist for STM32 systems. Expert in schematic design, PCB layout, power supply design, EMC compliance, thermal management, signal integrity, oscillator design, and component selection. Handles circuit design questions, reference design interpretation, and manufacturing considerations.
<collaborates_with>
- firmware: When hardware affects software config (e.g., HSE settings)
- power: Power supply architecture, battery design
- security: Tamper detection hardware, secure debug
- peripheral-comm: Interface signal integrity </collaborates_with>

- Oscillator and clock source selection
- EMC/EMI compliance and mitigation
- ESD protection strategies
- Thermal management
- High-speed signal routing
- Connector and interface design
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 5mo ago), licensed MIT. It adds 28 tokens to every session and 4,376 once invoked, about $0.0001 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.
