## What it does

The skill searches by MPN, DigiKey part number, description, or keywords. Through the Product Information API v4, it retrieves product parameters, pricing, stock, datasheet links, and related details. It can also fetch expanded data for a specific part.

For KiCad schematics, the skill extracts MPNs, downloads missing datasheets, and keeps a local datasheets directory maintained. Batch seeding is available with `--mpn-list`, so that workflow can run without a KiCad project.

You need DigiKey OAuth 2.0 credentials in advance: `DIGIKEY_CLIENT_ID` and `DIGIKEY_CLIENT_SECRET`. Check API access before relying on the skill, because searches and downloads through the API depend on those variables.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add aklofas/kicad-happy --skill digikey -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add aklofas/kicad-happy --skill digikey -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add aklofas/kicad-happy --skill digikey -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install aklofas/kicad-happy digikey
```

2. **Manually: put the files in place**
- File: `.github/skills/digikey/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add aklofas/kicad-happy --skill digikey -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/aklofas/kicad-happy --path skills/digikey
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add aklofas/kicad-happy --skill digikey -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/aklofas/kicad-happy/tree/HEAD/skills/digikey/SKILL.md

## When to use it
- find a component by MPN or keyword
- check a part’s price and stock
- download datasheets from a schematic
- sync a local datasheets directory
- seed datasheets from an MPN list

## Example prompts
- Search DigiKey for the part `GRM155R71C104KA88D` and show its price, stock, and key parameters.
- Extract MPNs from my KiCad schematic, download missing datasheets, and sync the local datasheets directory.
- Use `--mpn-list` to process this parts list and download the matching datasheets without a KiCad project.

description: >-
  Search DigiKey for electronic components and download datasheets — primary
  source for prototype orders and the preferred API method for fetching
  datasheets. Find parts by keyword or MPN, check pricing/stock, download
  datasheets via API, analyze specifications. Sync and maintain a local
  datasheets directory — extract components from schematics, download missing
  datasheets, keep them up to date. Also supports batch MPN-list seeding
  (`--mpn-list`) for bulk workflows without a KiCad project. Use when the user asks about electronic
  components, part specs, datasheets, pricing, stock, footprints, or needs to
  download a datasheet — even without mentioning "DigiKey". Also for "sync
  datasheets", "download datasheets for my board/project", or mentions a
  datasheets directory. DigiKey is the default distributor for prototyping. For
  BOM workflows, see the bom skill.

## Related Skills

| Skill | Purpose |
|-------|---------|
| `kicad` | Schematic analysis — extracts MPNs for datasheet sync |
| `bom` | BOM management — orchestrates sourcing across distributors |
| `spice` | Uses DigiKey parametric data for behavioral SPICE models |

DigiKey is the **primary source for prototype orders** (Mouser is secondary). Its API returns direct PDF datasheet links, making it the preferred datasheet source. For production orders, see `lcsc`/`jlcpcb`. For BOM management and export workflows, see `bom`.

## API Credential Setup

The DigiKey API requires OAuth 2.0 credentials. Here's how to set them up:

1. **Create a DigiKey account** at [digikey.com](https://www.digikey.com) if you don't have one
2. **Register an API app** at [developer.digikey.com](https://developer.digikey.com):
   - Sign in with your DigiKey account
   - Go to "My Apps" → "Create App"
   - App name: anything (e.g., "kicad-happy")
   - Select **"Product Information v4"** API
   - OAuth type: **Client Credentials** (2-legged, no user login needed)
   - Callback URL: `https://localhost` (not used for client credentials, but required)
   - After creation, note the **Client ID** and **Client Secret**
3. **Set the environment variables** before running the scripts:
   ```bash
   export DIGIKEY_CLIENT_ID=your_client_id_here
   export DIGIKEY_CLIENT_SECRET=your_client_secret_here
   ```
   If credentials are stored in a central secrets file (e.g., `~/.config/secrets.env`), load them first:
   ```bash
   export $(grep -v '^#' ~/.config/secrets.env | grep -v '^$' | xargs)
   ```

The client credentials flow has no user interaction — once configured, API calls work automatically.

## DigiKey Product Information API v4

The API is the preferred way to search DigiKey. It returns structured JSON with full product details, pricing, stock, datasheets, and parametric data.

**Base URL:** `https://api.digikey.com`

### Authentication

All API requests require OAuth 2.0. Use the **client credentials flow** (2-legged). Credentials must be loaded as environment variables (see "API Credential Setup" above).

```bash
curl -s -X POST https://api.digikey.com/v1/oauth2/token \
````
