# MPM Part Number Manager

**CW-018 | Status: Proposed | Priority: High**

A CoWork skill that gives any Claude session the ability to create correctly formatted MPM part numbers from plain-language descriptions, and to audit existing part numbers against the v1.4 SKU schema.

---

## Architecture

This skill follows **Option A — Reference, Do Not Embed.**

All taxonomy data lives in the MPM Google Drive Shared Drive and is read at runtime. Nothing schema-specific is locked inside the skill files. This allows 10+ CoWork users to update taxonomy without requiring skill updates.

### What Lives in This Repo

| File | Purpose |
|---|---|
| `SKILL.md` | Entry points, logic, decision trees, Google Drive file paths |
| `audit-rules.md` | Discrete validation rules — logic only, no taxonomy data |

### What Lives in Google Drive (referenced at runtime)

| File | Contents |
|---|---|
| `MPM_SKU_System_Reference.md` | Full v1.4 schema — authoritative |
| `MPM_SKU_Sequence_Tracker.md` | Current pool state + assignment history |
| `MPM_SKU_Decision_Log.md` | Dated taxonomy rulings *(to create)* |
| `MPM_SKU_Undocumented_Subtypes.md` | Sub-types in use, not yet in schema *(to create)* |
| `MPM_SKU_Skill_BuildBrief.md` | Full build brief with all context and open decisions |
