Pinout Lookup Skill

I am still actively pondering this but I have been doing a ton of electronics work recently, it's really fun!

The Pinout Lookup Skill is a skill that:

  1. Has ascii pinout diagrams for boards
  2. Has a skill to thoughtfully recommend wiring between boards, see below
  3. Recommends the agent create a standardized WIRING.MD in the project its working on to catalog what boards and components are used in the project
  4. Asks for contributions in the form of Pull Requests to add more ascii pinout diagrams to the repo.

Why?

The Claude internal memory of wiring diagrams goes stale super fast, and there is a ton of variants — it often gives me the wrong wiring.

Similarly thinking about where to wire is annoying — particularly if then coding (particularly Claude coding!) on where you wired. Having WIRING.MD allows Claude to know canonically what is wired where.

Finally, this seems like a good example of a crowd sourced repo — there are millions of board variants. Lets capture them all!!
