project-starbeam: Instructions file for Codex

AGENTS.md

project-starbeam AGENTS.md is an instructions file for Codex, OpenCode from dkyazzentwatwa/project-starbeam. It costs 3,979 tokens per session, scanned C, original, Apache-2.0.

Repository guidance for coding agents working on Starbeam V2, an ESP32-based system for analysing and transmitting radio signals across several frequency bands.

In plain words
What is it for?
Use it when compiling firmware, testing builds without hardware, monitoring serial output, or changing the radio-analysis platform.
Why use it?
It provides the project overview, build commands, hardware connection details, and legal limits around radio transmission and security testing.

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

This is dkyazzentwatwa/project-starbeam's own configuration. It tells Codex and OpenCode how to work on project-starbeam 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 project-starbeam 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 C, and why

project-starbeam AGENTS.md scanned grade C with 2 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 9d 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.

This file provides guidance to Codex (Codex.ai/code) when working with code in this repository.

Quick Reference Commands

# Compile and upload V2 firmware (ALWAYS use huge_app partition!)
arduino-cli compile --upload --fqbn esp32:esp32:esp32:PartitionScheme=huge_app -p /dev/cu.SLAB_USBtoUART starbeam_v2/

# Test compilation without hardware
./test_build.sh

# Monitor serial output
screen /dev/cu.SLAB_USBtoUART 115200

# Port names: macOS=/dev/cu.*, Linux=/dev/ttyUSB0, Windows=COM3

Project Overview

Project Starbeam V2 is a multi-band RF signal intelligence platform built around the ESP32-WROOM-32D microcontroller with multiple RF modules (NRF24L01 and CC1101) for signal analysis, generation, and manipulation across 2.4 GHz and 433 MHz bands. It includes optional HackRF One integration for extended frequency coverage up to 6 GHz.

CRITICAL LEGAL NOTICE: This is a security research and educational platform. RF transmission, jamming operations, and WiFi security testing features are strictly regulated. Only operate on permitted frequencies with proper authorization. This tool is intended for authorized security testing, educational contexts, and research environments.

Important: Repository Structure

This repository contains two firmware versions:

  • starbeam_v1/ - Original monolithic firmware (~1000+ line single .ino file)
  • starbeam_v2/ - Modular refactored firmware (current development focus)

Unless explicitly working on V1, all development should target starbeam_v2/.

Development Environment Setup

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.

project-starbeam AGENTS.md is an instructions file published in the GitHub repository dkyazzentwatwa/project-starbeam (313 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 3,979 tokens to every session, about $0.0199 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
