# PM Visualizer Skill
This skill converts unstructured Product Manager thoughts into a structured Excalidraw visualization.
## Features - **Smart Layout**: Automatically columns "Why, What, How" and creates a horizontal flow for "User Journey". - **Color Coding**: Visual distinction between problem (Why - Yellow), solution (What - Green), implementation (How - Blue), and flow (Journey - Red/Pink). - **Grouped Elements**: Text is properly bound to containers so they move together.
## Workflow
1. **Analyze Request**: Extract the following sections from the user's prompt or context: * **Title**: The feature or product name. * **Why**: The problem statement, business goals, or "Why are we building this?". * **What**: The solution requirements, features, or "What is it?". * **How**: Technical implementation details, API strategy, or "How will we build it?". * **Journey**: A sequential list of steps for the user journey or process flow.
2. **Prepare Data**: Create a JSON file (e.g., `temp_visual_data.json`) with this structure: ```json { "title": "Feature Name", "why": ["Reason 1", "Reason 2"], "what": ["Feature 1", "Feature 2"], "how": ["Tech 1", "Tech 2"], "journey": ["Step 1", "Step 2", "Step 3"] } ```
3. **Generate Diagram**: Run the python script to generate the `.excalidraw` file. ```bash python3 skills/pm-visualizer/scripts/layout_diagram.py temp_visual_data.json ~/Downloads/Documents/PM_Visuals/Output_Name.excalidraw ``` *Ensure the output directory exists first.*
4. **Cleanup**: Delete the temporary JSON input file.
5. **Report**: Inform the user the file is ready at the output path.
## Example
**User:** "Visualize a new 'Login with Google' feature. Why? Reduce friction. What? Google button on login page. How? OAuth2. Journey: User clicks button -> Google Popup -> Redirect to Dashboard."
**Codex Action:** 1. Create `login_spec.json`: ```json { "title": "Login with Google", "why": ["Reduce friction", "Increase conversion"], "what": ["Google Sign-in Button", "Profile Sync"], "how": ["OAuth 2.0 Flow", "Google Identity SDK"], "journey": ["User clicks 'Sign in with Google'", "Google permissions popup appears", "User approves access", "System verifies token", "User redirected to Dashboard"] } ``` 2. `mkdir -p ~/Downloads/Documents/PM_Visuals` 3. `python3 skills/pm-visualizer/scripts/layout_diagram.py login_spec.json ~/Downloads/Documents/PM_Visuals/Login_Spec.excalidraw`
