Altium Claude Skills

Claude Code skills for Altium hardware design: symbol and footprint authoring, schematic review, and PCB placement.

Written while taking one real board (175 components) from schematic review through to placement.

Skill	What it does
altium-library	Author and verify symbols (.SchLib) and footprints (.PcbLib) as code, including measuring datasheets and 2D drawings
altium-schematic-review	Review a schematic (.SchDoc) — find unconnected pins, missing footprints and net errors, then judge each one against the datasheet
altium-pcb-placement	PCB placement — derive board size, decide rotation for main ICs and connectors, produce a 1:1 placement plan, inject coordinates, check overlaps. It does not route

Install

**Windows + PowerShell only** — junctions (`New-Item -ItemType Junction`) and Altium itself are Windows things.

You can hand this repo URL to Claude Code and say "install this". Steps 1-3 below are what it needs to do.

1. Clone

Clone somewhere you **will not move**. The junctions in step 3 bake an absolute path, so relocating the folder later means recreating them.

git clone https://github.com/ScottJeong/altium-claude-skills.git C:\tools\altium-claude-skills

2. Python 3.12 venv

This is what the scripts run on. **Do this before the junctions** — the skills will trigger without it, and then every script fails. Why 3.12, and the MCP setup, are under [Requirements](#requirements).

py -3.12 -m venv C:\tools\edatools
C:\tools\edatools\Scripts\python.exe -m pip install altium-monkey pymupdf
C:\tools\edatools\Scripts\python.exe -c "import altium_monkey, pymupdf; print('ok')"

3. Link the three skills as junctions

Into `~/.claude/skills/`. Unlike symlinks, junctions need no admin rights, and sync clients see them as ordinary folders.

$repo = "C:\tools\altium-claude-skills"      # wherever you cloned in ste
