electronic-mcp-server: Skill for Claude Code

.github/skills/circuit-debugger/SKILL.md

circuit-debugger is a skill for Claude Code, Codex from wedsamuel1230/electronic-mcp-server. It costs 74 tokens per session (1,821 once invoked), scanned A, a copy of circuit-debugger, MIT.

A step-by-step troubleshooting guide for Arduino, ESP32, and RP2040 electronic circuits. It uses checks such as visual inspection, power testing, continuity testing, and signal tracing, and includes scripts for generating test sketches.

In plain words
What is it for?
Use it to investigate unresponsive sensors, unlit LEDs, non-working motors, intermittent faults, unexpected signals, and other hardware problems, including by generating I2C, GPIO, ADC, or PWM test sketches.
Why use it?
It provides a method for narrowing down whether a circuit problem comes from power, wiring, pins, sensors, or another part. This is useful when a board has no power, a component becomes hot, or behaviour works only sometimes.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one.

This is wedsamuel1230/electronic-mcp-server's own configuration. It tells Claude Code and Codex how to work on electronic-mcp-server 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 electronic-mcp-server 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

circuit-debugger 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/generate_debug_sketch.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.

How it starts

The opening of the file, as written. The whole thing — 240 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Circuit Debugger

Systematic approach to diagnosing hardware issues in maker projects.

Resources

This skill includes bundled tools and references:

  • scripts/generate_debug_sketch.py - Arduino sketch generator for I2C scanner, GPIO tester, ADC checker, PWM tester
  • references/measurement-procedures.md - Comprehensive multimeter and oscilloscope guide

Quick Start

Generate I2C scanner:

uv run scripts/generate_debug_sketch.py --i2c --output i2c_scanner.ino

Generate GPIO tester:

uv run scripts/generate_debug_sketch.py --gpio --pins 2,3,4,5 --output gpio_test.ino

Generate all debug sketches:

uv run scripts/generate_debug_sketch.py --all

Interactive mode:

uv run scripts/generate_debug_sketch.py --interactive

Trigger Phrases

  • "My circuit doesn't work"
  • "Component is getting hot"
  • "No power to the board"
  • "Sensor not responding"
  • "Intermittent/random failures"
  • "Works sometimes, not others"

Debugging Protocol

Phase 1: Power System Check (Do First!)

Visual Inspection (30 seconds)

□ Check for smoke, burn marks, or melted plastic
□ Verify power LED on microcontroller is lit
□ Look for loose wires or cold solder joints
□ Confirm correct polarity on polarized components (LEDs, caps, diodes)

Multimeter Tests (Set to DC Voltage)

Test Point              | Expected Value  | If Wrong
------------------------|-----------------|------------------
VCC to GND on MCU       | 3.3V or 5V      | Check regulator, power source
Sensor VCC pin          | Match datasheet | Check wiring, broken trace
Motor driver VCC        | Logic + Motor V | Separate supplies needed?
Battery terminals       | Rated voltage   | Dead/discharged battery

Common Power Issues:

Symptom Likely Cause Fix
No voltage anywhere Disconnected power, blown fuse Check continuity from source
Low voltage (< 4V when expecting 5V) Overloaded supply, bad regulator Reduce load, check current draw
Voltage drops under load Undersized power supply Calculate total current, upgrade PSU
Reverse polarity Swapped wires Check all connections, may have damaged components

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.
