Is the GPIO Config skill free?

Yes. The skill itself is free from claudius-ars/embedded-agent-skills. SkillProof publishes the install command and an independent test verdict at no cost.

What is the GPIO Config SkillProof Score?

7.6/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 7/10, docs & honesty 2/5.

How do I install GPIO Config?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use GPIO Config with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Test report

Verdict: Works with setup
Score: 7.6/10
Tested: Jul 15, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · 084a891

Real, working pin-safety logic — validate_pinmap.py correctly caught a GPIO2 strapping-pin hazard on an ESP32 status LED that a naive baseline answer would have missed. But the script crashes on the exact JSON the docs teach: SKILL.md's own schema and worked Section-8 example pass protocol_bus as an integer (0, 1), while the code calls protocol_bus.lower() expecting a string like "i2c" — AttributeError: 'int' object has no attribute 'lower'. Fix is to pass protocol_bus as a lowercase protocol name string, undocumented.

What GPIO Config does

Assigns and validates GPIO pin maps for Raspberry Pi and ESP32 boards, flagging strapping pins, flash-reserved pins, and current-budget issues before they brick hardware. Triggers on GPIO/wiring/pin-conflict questions or when a named sensor/board pair (e.g. 'BME280 on a Pi 4') implies pin selection, and generates gpiozero/RPi.GPIO/Arduino/ESP-IDF init code.

How to install GPIO Config

git clone https://github.com/claudius-ars/embedded-agent-skills
cd embedded-agent-skills
mkdir -p ~/.claude/skills
cp -r embedded-agent-skills/gpio-config ~/.claude/skills/gpio-config

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.

Commands — how to trigger GPIO Config

/gpio-config GPIO pin assignment, conflict validation, and init code for Pi and ESP32.

It also activates on plain-language prompts like these:

Wire a BME280 and an SSD1306 OLED to my ESP32 over I2C, give me the pins
Check this Raspberry Pi pinout for strapping-pin or current-budget conflicts
Generate gpiozero init code for a sensor I'm wiring to a Pi 4
