+User: "Create issues from our product doc" or "--from-doc"
+
+[Skill searches for PRODUCT.md, ARCHITECTURE.md, IMPLEMENTATION.md]
+[Finds PRODUCT.md with feature descriptions]
+
+Skill: I found PRODUCT.md which describes the following features:
+  - User authentication with SSO
+  - Usage metrics dashboard
+  - Export functionality
+
+Based on the document, I propose:
+
+**Project**: User authentication with SSO support
+  (From PRODUCT.md: "Users need secure login with enterprise SSO...")
+
+**Issues**:
+  1. "Implement basic email/password authentication"
+     # Background
+     From PRODUCT.md: Users need secure login...
+
+     # Outcome
+     - [ ] Users can register with email/password
+     - [ ] Users can log in and log out
+
+  2. "Integrate SAML SSO provider"
+     ...
+
+Which features would you like me to create issues for?
