stmllm cpp-firmware.instructions.md

stmllm cpp-firmware.instructions.md is an instructions file for GitHub Copilot from vinn-ie/stmllm. It costs 824 tokens per session, scanned A, original, no licence file.

A set of coding rules for C++ firmware, which is software that runs directly on embedded hardware. It covers embedded C++ choices to make or avoid, class design, and connections to hardware abstraction layers.

In plain words
What is it for?
Writing or reviewing C++ firmware, designing classes, and integrating code with a hardware abstraction layer.
Why use it?
It gives the agent project-specific guidance for writing firmware that fits the project’s design and hardware integration rules.

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

stmllm cpp-firmware.instructions.md 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 3d 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.
