simulink-optimizing-embedded-code

simulink-optimizing-embedded-code is a skill for Claude Code, Codex from matlab/simulink-agentic-toolkit. It costs 174 tokens per session (3,410 once invoked), scanned A, original, no licence file.

A workflow for optimizing Simulink models for Embedded Coder, which generates C code from models for embedded devices. It targets execution time, memory use, code size, data copies, and MISRA compliance, a safety-oriented C coding standard.

In plain words
What is it for?
Use it to improve Simulink-generated C code for runtime, RAM, ROM, stack, code size, data movement, or MISRA-related requirements.
Why use it?
Generated embedded code may be too slow, large, memory-heavy, or difficult to certify. This workflow focuses optimization on those concrete constraints while preserving the model's behavior.

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

simulink-optimizing-embedded-code 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 yesterday.

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.

The source is not reproduced here

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

Files

What ships with it

35 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.

Changes

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.

simulink-optimizing-embedded-code is a skill published in the GitHub repository matlab/simulink-agentic-toolkit (1,038 stars, last pushed yesterday), with no licence file. It adds 174 tokens to every session and 3,410 once invoked, about $0.0009 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 2026-09-03.
