Read this before starting to work on hardware projects.

Guide on producing the following docs for a hardware project: rendered schematic sheet, pin maps, BOM, and design notes.

Shop at online stores that speak the Universal Commerce Protocol (UCP) — run discovery, cart, and checkout over UCP's REST API and pay with Prava mandate credentials. Use when the user asks to buy, order, or purchase something online, wants to track an order, or mentions UCP or agentic checkout.

Guide on authoring valid .kicad_sch / .kicad_pro files as text: the live KiCad s-expression format and kicad-cli validation. Use when writing, generating, or editing a KiCad schematic or project by hand. Only use when the user explicitly requests KiCAD or PCBs.

Use when creating artifacts (rendered markdown docs, HTML pages, or self-contained React UI) for design previews, interactive mocks, or durable docs that can be iterated on.
