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 | $0.00006 | $0.00153 |
| Opus 5.5 | $0.00002 | $0.00061 |
| Sonnet 5.5 | $0.00001 | $0.00031 |
| Haiku 4.5 | $0.00001 | $0.00015 |
Grade A, and why
avr-bare-metal-embedded 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.

avr-bare-metal-embedded is a skill published in the GitHub repository MidOSresearch/midos (7 stars, last pushed 5mo ago), licensed MIT. It adds 6 tokens to every session and 153 once invoked, about $0.0000 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 2026-08-31.

cortex-m-patterns
Cortex-M code patterns for SysTick, NVIC priority grouping, FPU enable, MPU regions, AAPCS inline assembly, DWT cycle counting, vector table relocation, and WFI sleep entry. Use when writing core-level Cortex-M code or checking it against a known-good pattern.
bare-metal-patterns
Register-level C patterns for Cortex-M without a HAL: bit manipulation macros, GPIO and polled UART setup, SysTick timebase, interrupt-driven UART ring buffer, linker sections and map files, and weak default ISR handlers. Use when writing or reviewing HAL-free drivers and startup code.
bootloader-patterns
Bootloader patterns for STM32, nRF52, and SAM parts: boot decision tree, RTC backup register boot flags, dual-bank flash layout, YMODEM receive over UART, post-flash verification, and watchdog handling during boot. Use when building or reviewing the boot path of a device that updates in the field.
