Show HN: Playground for Designing Buildable Robotics

Developer JamelHammoud released Basecase, an open-source playground for designing buildable robotics that runs on macOS with Node.js 22 or later and installs via npm install and npm start. The optional AI agent connects to a locally running Claude Code instance through the Agent Client Protocol, and new catalog parts can be added by asking a coding agent to follow the add-part skill file. Formatting, lint rules and tests are enforced by a pre-commit hook, with npm run check required before pushing and npm run test:e2e after UI changes.

Basecase is a playground for designing buildable robotics.

The optional AI agent uses your locally running Claude Code through the Agent Client Protocol.

npm install
npm start

npm start builds the app and runs it at full speed. For development with hot reload, use npm run electron:dev.

Read AGENTS.md §0 first. Formatting, lint rules and tests are enforced by a pre-commit hook; run npm run check before you push, and npm run test:e2e after UI changes.

To add a part to the catalog, ask your coding agent to “add this part: ⟨link⟩”. It follows .agents/skills/add-part/SKILL.md, which you can also follow by hand.
