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:

   {
     "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.

   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:

   {
     "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
