+# Prompt Optimizer
 
-MPM Prompt Optimizer — Claude CoWork plugin that transforms rough requests into optimized, well-structured prompts. Conducts an adaptive interview, invokes the right skills automatically, and delivers a polished prompt ready to run.
+A Claude CoWork plugin for the MPM team that transforms rough requests into precise, well-structured prompts — getting dramatically better results from Claude with less trial and error.
+
+## What It Does
+
+When you have an idea but aren't sure how to ask Claude for it, the Prompt Optimizer steps in. It:
+
+1. **Asks how experienced you are** with Claude prompting — and calibrates how many questions it asks based on your answer (beginners get more guidance; advanced users get a faster, lighter-touch experience)
+2. **Interviews you** with just the right questions to fill in what's missing — audience, context, format, constraints
+3. **Automatically selects the right skills** — if you need a Word doc, it invokes the docx skill; a presentation, the pptx skill; branded content, the MPM brand voice skill — all woven in naturally
+4. **Shows you the optimized prompt** for review before running anything, with a clear explanation of what was improved
+5. **Saves the optimized prompt** as a downloadable `.md` file so you can reuse it anytime
+6. **Executes immediately** once you approve
+
+## How to Use It
+
+Just say any of the following:
+- "Optimize this prompt: [your rough idea]"
+- "Help me ask this better: [your request]"
+- "I'm not getting what I want from Claude — help me improve my prompt"
+- "Prompt optimizer"
+- "Make this clearer for Claude: [text]"
+
+## Skill
+
+| Skill | What it does |
+|---|---|
+| `optimize-prompt` | Full optimization workflow — interview, rewrite, review, save, execute |
+
+## Skills Integrated
+
+The optimizer is aware of all MPM skills and will automatically include the right ones:
+
+- `docx` — Word documents
+- `pptx` — Presentations and slide decks
+- `xlsx` — Spreadsheets
+- `pdf` — PDF creation and manipulation
+- `mpm-brand-voice:brand-voice-enforcement` — On-brand content
+- `odoo-mpm:odoo` — MPM business data lookups
+- `display-catalog:display-catalog` — MPM product specs (preferred source; falls back to Odoo)
+
+## Important: MPM Product Specs
+
+MPM manufactures all its own displays. The optimizer will never direct Claude to search the web for MPM product specifications — all spec lookups use internal sources only (Display Catalog skill or Odoo).
+
+## Installation
+
+Install via the Plugins panel in Claude CoWork.
