+🤖 HOW TO USE WITH YOUR AI AGENTS
+Simply give each AI agent one package at a time with this instruction format:
+For Archon (Step 1):
+Task: Set up NT8 SDK repository foundation
+Use the attached "Repository Setup Package"
+Follow every step in the setup instructions exactly
+Validate: Repository builds successfully with 0 warnings
+For Kilo (Step 2):
+Task: Implement all core interfaces
+Use the attached "Core Interfaces Package"  
+Create every file exactly as specified in the implementation checklist
+Validate: All unit tests pass with >85% coverage
+And so on through all 5 packages.
+✅ SUCCESS INDICATORS
+
+Green Light: AI agent reports task complete, validation passes
+Yellow Light: AI agent asks clarifying questions, validation has warnings
+Red Light: AI agent stuck >4 hours, validation fails
+
+🚨 IF PROBLEMS OCCUR
+
+AI agent reports errors: Give them the validation script to run and fix issues
+AI agent stuck: Switch the task to the other AI agent
+Validation fails: Have AI agent re-read the specific requirements and try again
+
+🎉 FINAL RESULT
+After all 5 packages are complete, you'll have:
+
