## Install

```sh
agentstack add skill-nickkraakman-skidl-skills-find-part
```

Requires the [AgentStack CLI](https://agentstack.voostack.com/docs/cli). Works with Claude Code, Cursor, and any MCP-compatible agent.

## About

# Find Part

## When to use
- Selecting components for a new circuit BOM
- Verifying stock, pricing, or lifecycle of a candidate MPN
- Retrieving a KiCad symbol/footprint for a specific part
- Invoked via `/skidl-ee:find-part` or called by agents (part-sourcer, orchestrator)

## Procedure

### Step 1 — Preferred: pcbparts MCP (live JLCPCB data)

For any query (MPN or description, e.g. "3.3V LDO 500mA SOT-23-5"):

| Task | Tool |
|------|------|
| Description search | `mcp__pcbparts__jlc_search` |
| Exact LCSC# / MPN | `mcp__pcbparts__jlc_get_part` |
| Stock check | `mcp__pcbparts__jlc_stock_check` |
| Cross-ref (DigiKey) | `mcp__pcbparts__digikey_get_part` |
| Cross-ref (Mouser) | `mcp__pcbparts__mouser_get_part` |
| KiCad symbol + footprint | `mcp__pcbparts__cse_get_kicad` |

If `pcbparts` MCP is not connected, warn before continuing:
```bash
echo "⚠️ pcbparts MCP not connected. Install: claude mcp add --transport http pcbparts https://pcbparts.dev/mcp"
```

### Step 2 — Fallback: SKiDL local library search

Use when pcbparts MCP is unavailable or a local KiCad symbol check is needed:
```bash
skidl-part-search ""          # all terms must match
skidl-part-search --limit 20 ""
skidl-part-search 'opamp (low-noise|dip-8)'  # OR within terms
skidl-part-search --interactive      # browse with pin details
```

## Sourcing Rules (always apply)

**JLCPCB tier priority:**
1. Basic — use whenever possible
2. Preferred — strongly preferred for production
3. Extended — only if no alternative (adds manual placement surcharge)

**Mandatory checks (flag anything that fails):**
- Stock > 100 units (warn if  0603 > 0805 > 1206

**Decision heuristics:**
- Jellybean passives → cheapest Basic part meeting spec
- Critical ICs (MCU, regulator, ADC) → Preferred tier + second-source check
- Regulated/automotive designs → AEC-Q100/Q200 when required

## Output

For each part found, produce one row in this format:
```
MPN | LCSC# | Stock | Unit Price | Package | JLCPCB Tier | KiCad Footprint | Notes
```

## Validation

- Do not use a part without confirming stock > 100 units
- Do not leave the KiCad footprint field blank before handing the part to skidl-coder
- Single-source and Extended-tier parts must have a `Notes` entry explaining the risk
