project-starbeam: Instructions file for Claude Code

CLAUDE.md

project-starbeam CLAUDE.md is an instructions file for Claude Code from dkyazzentwatwa/project-starbeam. It costs 3,980 tokens per session, scanned C, a copy of project-starbeam AGENTS.md, Apache-2.0.

Repository instructions for Claude Code covering an ESP32-based radio research project, including commands for compiling firmware, testing without hardware, and viewing device output.

In plain words
What is it for?
Use it when compiling or uploading Starbeam V2 firmware, running hardware-free build tests, or monitoring serial output from the device.
Why use it?
It gives the coding agent the project context and the commands needed to work with the code and connected hardware safely.

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

This is dkyazzentwatwa/project-starbeam's own configuration. It tells Claude Code 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 CLAUDE.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 10d 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.

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/.

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.
