embedded-project-setup

embedded-project-setup is a skill for Codex from Victory-7291/project-scaffold-setup-skills. It costs 95 tokens per session (3,727 once invoked), scanned A, original, MIT.

A setup guide for embedded firmware projects targeting microcontrollers such as STM32, ESP32, AVR, RP2040, and Nordic nRF devices.

In plain words
What is it for?
Use it to start or modernize firmware, configure cross-compilers and vendor SDKs, create builds with CMake and Ninja, and prepare flashing, debugging, and CI.
Why use it?
It separates the ordinary build process from device-specific compiling, flashing, and debugging, making firmware projects easier to reproduce and maintain.

Skill for Codex

Written for Codex: agents/openai.yaml present.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is bash scripts/format.sh --check.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

embedded-project-setup 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 2mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/scaffold_embedded_project.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Modern Embedded Project Setup

Overview

Create or modernize embedded firmware around a shared engineering pipeline, then adapt the target-specific compiler, SDK, flashing, and debug pieces to the selected MCU:

VS Code -> clangd -> clang-format -> clang-tidy -> CMake/CMakePresets -> Ninja -> target compiler/SDK -> firmware artifacts -> flash/debug -> MCU

Treat editor analysis, static checks, build generation, cross compilation, artifact generation, flashing, and debug as separate stages. First classify the user's working directory and host platform, then either generate a greenfield scaffold or modernize the existing firmware pipeline.

Workflow

  1. Determine the user's working directory and whether firmware already exists.

    • Check the user-provided path or current working directory before writing files.
    • Treat the directory as an existing firmware project if it already has source files, linker scripts, startup files, CubeMX files, CMake/Make/build scripts, vendor trees, flash/debug scripts, editor settings, CI, docs, or git history.
    • For existing firmware, inventory the full development pipeline before editing: build system, toolchain file, compiler version, MCU/board assumptions, linker/startup flow, vendor dependency model, flash/debug flow, tests or host-side checks, formatting/linting/static analysis, CI, and firmware artifacts.

  2. Detect the user's host development environment.

    • Determine OS and architecture: macOS/Linux/Windows plus arm64 or x64. Use local commands such as uname -s, uname -m, or PowerShell/.NET runtime information where appropriate.
    • Select a host profile: macos-arm64, macos-x64, linux-x64, linux-arm64, windows-x64, or windows-arm64.
    • If the agent is running somewhere other than the user's real development machine, ask for the user's OS/architecture instead of assuming the sandbox matches their workstation.

  3. Identify the firmware target before writing files.

    • Capture target ecosystem first: STM32/Cortex-M, ESP32/ESP-IDF, AVR/Arduino or bare-metal avr-gcc, RP2040/Pico SDK, Nordic nRF/nRF Connect SDK or Zephyr, Zephyr/RTOS board target, or another MCU family.
    • Capture the concrete MCU or board, firmware package/SDK, dependency path, package version/tag, debug probe, flash/RAM map when relevant, CPU core, FPU/float ABI when relevant, flash tool, debug server, and whether the project will use vendor HAL/SDK, RTOS APIs, CMSIS, bare-metal register access, or a mix.
    • If the user has not provided the target, ask for the MCU/board and preferred framework before writing files. Do not silently default to any STM32, ESP32, AVR, RP2040, Nordic, or Zephyr board.
    • If the user explicitly wants a target-agnostic starter before hardware is known, generate only a portable build-smoke scaffold with no hardware register writes, no final flash command assumptions, and clear TODOs for target selection.

What ships with it

15 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.

It adds 95 tokens to every session and 3,727 once invoked, about $0.0004 per session on Opus 5.5. 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 2026-08-31.
