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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00104 | $0.00735 |
| Opus 5.5 | $0.00042 | $0.00294 |
| Sonnet 5.5 | $0.00021 | $0.00147 |
| Haiku 4.5 | $0.00010 | $0.00073 |
Grade A, and why
REPLACE-with-skill-name 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 6d 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 — 75 lines — stays where its author put it; the contents beside it link to each section on GitHub.
()
<One paragraph: what this board is, and what the reference files hold. Say explicitly that the detail lives in the reference files and should be read rather than guessed at.>
reference/board-hardware.md—reference/recipes.md—template/— a complete working project that builds and flashes, plus a scaffolding script.
Orientation
| MCU | <part number, core, flash, RAM, package> |
| Clocks | <crystals populated, and the clock tree that is known to work> |
| Display | <controller, resolution, bus, pins> |
| LED / button | <pin and polarity for each> |
| Storage | <internal / external flash, SD, PSRAM, with addresses> |
| USB | <peripheral, pins, bootloader behaviour> |
| Debug | <SWD/JTAG/UART header and pins> |
<Delete rows that don't apply; add rows the board needs.>
Rules that prevent the expensive mistakes
<10–15 numbered rules from your bring-up log. Each is imperative and carries its consequence. Template for one entry:>
<the setting, in code form>— . Without it, <the symptom, which should not obviously point back at this setting>.
When the task is
<The one or two areas where the naive approach is badly wrong. Give the mechanism and the numbers, so the model can generalise past the case you wrote down. Delete if the board has none.>
Starting a new project
Do not hand-assemble one. template/ is a verified-working project — scaffold from it:
Run from the directory containing this SKILL.md; use an absolute path for the new project.
./template/variants/new-project.sh <target-dir> [--full|--minimal]
cd <target-dir> && <build command>
--full(default) — . .--minimal— . . Use it to prove the toolchain and the flashing route before adding anything.
When the user already has a project, prefer bringing it in line with the template's
<config file> over rewriting their code.
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

REPLACE-with-skill-name is a skill published in the GitHub repository alexex1993/mcu-skills (25 stars, last pushed 7d ago), licensed MIT. It adds 104 tokens to every session and 735 once invoked, about $0.0004 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.
