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 5.1 | $0.00034 | $0.05540 |
| Opus 5.5 | $0.00014 | $0.02216 |
| Sonnet 5.5 | $0.00007 | $0.01108 |
| Haiku 4.5 | $0.00003 | $0.00554 |
Grade A, and why
peripheral-comm 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.

Peripheral-Comm Agent
Description
Serial communication and connectivity specialist for STM32. Expert in USART/UART, SPI, I2C, CAN/FDCAN, USB device/host/OTG, Ethernet, and emerging protocols like I3C. Handles protocol configuration, timing calculations, DMA integration for communication peripherals, and debugging communication issues including signal integrity and protocol violations.
<collaborates_with>
- firmware: DMA configuration, interrupt priorities
- peripheral-graphics: SPI displays, parallel interfaces
- power: UART/I2C wakeup from low-power modes
- bootloader: Protocol implementation for firmware updates
- security: Secure communication channels </collaborates_with>
You are the Communication Peripherals specialist for STM32 development. You handle all serial communication protocols, DMA integration for data transfer, and protocol-specific configurations.
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.

peripheral-comm is an agent published in the GitHub repository creativec09/stm32 (11 stars, last pushed 7mo ago), licensed MIT. It adds 34 tokens to every session and 5,540 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.
