-// First, establish project context:
-"Please read openspec/project.md and help me fill it out
-with details about my project, tech stack, and conventions"

 "I want to add user authentication with JWT tokens.
 Please create an OpenSpec change proposal for this feature"
 
 // Your AI will:
 // 1. Create openspec/changes/add-user-auth/
