# tscircuit

Guides your agent through electronics design in tscircuit: picking parts, routing traces, running checks. Useful when the schematic lives in TSX.

## What it does

The skill activates when you create, edit or debug a circuit in tscircuit, the React/TypeScript way to build PCBs. The agent drives the `tsci` CLI: searches footprints, installs registry packages, builds the project and validates it. The workflow is spelled out — clarify power rails, connectors and manufacturer limits first, pick a starting point, then write code.

Parts come from `tsci search`, with `--digikey` and `--mouser` flags when stock and supplier part numbers matter. Installation goes through `tsci add <author/pkg>` or `tsci import <query>`. For USB-C receptacles the skill prefers the builtin `<connector standard="usb_c" />` syntax over a JLCPCB import. Schematics get split into sheets and sections with `<schematicsheet>` and `<schematicsection>`, and on larger boards components are grouped by function: power, MCU, IO.

Checks run in order. `tsci check netlist` comes before placement checks, then `tsci check schematic-placement` and `tsci check placement`, and only after those `tsci build`. There is also `tsci check shorts`, which looks for unintended copper bridges and exits nonzero when it finds one. Treat that failure as real, not as a generic DRC warning: open `checks/check-shorts/bitmap.png` and fix the copper. The skill asks for the builtin autorouter and documented APIs, and a custom router only when you explicitly request one.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add tscircuit/skill --skill tscircuit -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/tscircuit/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/tscircuit/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add tscircuit/skill --skill tscircuit -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/tscircuit/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add tscircuit/skill --skill tscircuit -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/tscircuit/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install tscircuit/skill tscircuit
```

2. **Manually: put the files in place**

npx skills add tscircuit/skill --skill tscircuit -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/tscircuit/skill
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/tscircuit/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add tscircuit/skill --skill tscircuit -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/tscircuit/skill/tree/HEAD/SKILL.md

## When to use it
- build a device schematic from React components
- find a footprint with supplier stock and part number
- route traces with the builtin autorouter
- catch copper shorts before sending the board to fab
- split a large schematic into sheets and sections

## Example prompts
- Build a 5V buck converter schematic in tscircuit
- Search for a USB-C receptacle with tsci search and add it
- Run tsci check placement and fix the violations

description: Use this skill when creating, editing, or debugging electronic circuits, schematics, or PCB layouts with tscircuit, including React/TypeScript circuit code. Invoke for component and footprint selection, electrical connections, schematic organization, PCB placement, trace routing, routing failures, design checks, and fabrication exports—even when the user does not mention the CLI. Use tscircuit's built-in autorouting and documented APIs; do not implement a custom router unless the user explicitly requests one.

# tscircuit

You are helping the user design electronics using tscircuit (React/TypeScript) and the `tsci` CLI.

When this Skill is active:

- Prefer tscircuit’s documented primitives and CLI behavior. If something is unclear, confirm by:
  - Reading local files in the repo (e.g., `tscircuit.config.json`, `index.circuit.tsx`, `package.json`)
  - Running `tsci --help` or the specific subcommand’s `--help`
- Avoid “inventing” JSX props or CLI flags.

## Default workflow

1) Clarify requirements (if not already given)
- Board form factor / size constraints
- Power sources and voltage rails
- I/O: connectors, headers, mounting holes, mechanical constraints
- Target manufacturer constraints (trace/space, assembly, supplier)

2) Choose a starting point
- If the repo is not a tscircuit project, recommend:
  - Install CLI, then `tsci init` to bootstrap a project.
- If a form-factor template is appropriate (Arduino Shield, Raspberry Pi HAT, etc.), prefer `@tscircuit/common` templates.

3) Find and install components
- Use `tsci search "<query>"` to discover footprints and tscircuit registry packages.
- Use `tsci search --digikey "<query>"` or `tsci search --mouser "<query>"` when distributor stock and supplier part numbers matter. Both flags can be combined, and `--json` provides machine-readable results.
- For USB-C receptacles/connectors, prefer builtin syntax with `<connector standard="usb_c" />` instead of importing from JLCPCB.
- Use one of:
  - `tsci add <author/pkg>` for registry packages (installs `@tsci/*` packages)
  - `tsci import <query>` when you need to import a component from JLCPCB or the registry.
- DigiKey and Mouser search results are for part discovery; `tsci import` does not directly import from those distributors.

4) Write/modify TSX circuit code
- Keep circuits as a default-exported function that returns JSX.
- Nearly every schematic should be broken up using `<schematicsheet>` and `<schematicsection>` to organize related circuitry into clear, readable sheets and sections.
