embedeval: Instructions file for Claude Code

CLAUDE.md

embedeval CLAUDE.md is an instructions file for Claude Code from Ecro/embedeval. It costs 5,344 tokens per session, scanned A, original, Apache-2.0.

Project instructions for EmbedEval, a Python benchmark for testing AI models on embedded-firmware development. They describe its tools, supported embedded platforms, project layout, and common commands.

In plain words
What is it for?
Use them when developing, testing, or documenting EmbedEval, including work involving Zephyr, FreeRTOS, ESP-IDF, STM32, Linux drivers, or Yocto.
Why use it?
They give an agent the project context needed to work consistently in the repository without guessing how it is organized or run.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions CLAUDE.md.

This is Ecro/embedeval's own configuration. It tells Claude Code how to work on embedeval itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything embedeval configures →

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else. The line is /home/noel/embedeval.

Borrowing it

Nothing to install: this file belongs to Ecro/embedeval. Take a copy, put it at the same path in your own repository, and replace the rules that are about this project with yours.

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

embedeval CLAUDE.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 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.
