eAI: Instructions file for Codex

AGENTS.md

eAI AGENTS.md is an instructions file for Codex, OpenCode from embeddedos-org/eAI. It costs 998 tokens per session, scanned A, original, MIT.

Role instructions for eAI, dividing software work among planning, architecture, backend, frontend, testing, security, performance, and review roles.

In plain words
What is it for?
Use them to guide agents through planning tasks, designing structure, building APIs or interfaces, testing, checking security and performance, and reviewing completed work.
Why use it?
They clarify who owns each part of a change and keep implementation separate from approval, which helps reduce missed problems during review.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions AGENTS.md.

This is embeddedos-org/eAI's own configuration. It tells Codex and OpenCode how to work on eAI 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 eAI configures →

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

eAI AGENTS.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.

The opening of the file, as written. The whole thing — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md — eAI

eAI (CMake project EAI, v0.2.0) is the on-device AI layer of the EmbeddedOS ecosystem, written in C (C11): a runtime contract for loading and running models plus build-selectable runtimes — EAI-Min (lightweight agent runtime for IoT devices) and EAI-Framework (industrial platform) — with model-format loaders, optional hardware-accelerator backends, a brain-computer-interface module, a CLI, and host/embedded platform adapters. (Provenance: README.md intro, CMakeLists.txt project()/options.)

Layout (from README.md "What's inside")

  • common/ — shared contracts and utilities (types, config, logging, model manifest, runtime contract, tool registry, security/permissions); builds eai_common
  • platform/ — platform adapters (Linux, Windows, macOS, Android, iOS, container, Zephyr, FreeRTOS, bare-metal, EoS); builds eai_platform
  • min/ — EAI-Min lightweight agent runtime (agent loop, router, KV memory)
  • framework/ — EAI-Framework industrial platform (runtimes, connectors, orchestrator, policy, observability)
  • bci/ — brain-computer-interface module
  • models/ — model manifests and metadata
  • accel/ — accelerator backends (optional Vulkan Compute, CoreML/Metal, Qualcomm QNN)
  • formats/ — model format loaders
  • cli/ — eai command-line tool
  • bindings/ — C++ and Python bindings
  • profiles/ — example profiles: adaptive-edge, bci-assistive, industrial-gateway, mobile-edge, robot-controller, smart-camera
  • tests/ — C tests plus unit/, functional/, performance/, simulation/ Python suites
  • cmake/toolchains/, ci/, docs/, tools/ — cross-compile toolchains, CI build/test scripts, docs, developer tools

CODE_STRUCTURE.md is the detailed, module-by-module developer reference.

Build (from README.md "Build" and CMakePresets.json)

Requires CMake ≥ 3.16 and a C compiler. CMakePresets.json defines the host/target presets used by CI (e.g. linux-x64-release).

cmake --preset linux-x64-release
cmake --build --preset linux-x64-release

# or without presets
cmake -B build -DCMAKE_BUILD_TYPE=Release
cmake --build build --parallel

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.
