Comprehensive guide to Antigravity Manager architecture, workflows, and development. Use this to understand how to work on the project.

Verify implementation matches change artifacts. Use when the user wants to validate that implementation is complete, correct, and coherent before archiving.

Sync delta specs from a change to main specs. Use when the user wants to update main specs with changes from a delta spec, without archiving the change.

Guided onboarding for OpenSpec - walk through a complete workflow cycle with narration and real codebase work.

Start a new OpenSpec change using the experimental artifact workflow. Use when the user wants to create a new feature, fix, or modification with a structured step-by-step approach.

Fast-forward through OpenSpec artifact creation. Use when the user wants to quickly create all artifacts needed for implementation without stepping through each one individually.

Enter explore mode - a thinking partner for exploring ideas, investigating problems, and clarifying requirements. Use when the user wants to think through something before or during a change.

Continue working on an OpenSpec change by creating the next artifact. Use when the user wants to progress their change, create the next artifact, or continue their workflow.

Archive multiple completed changes at once. Use when archiving several parallel changes.

Archive a completed change in the experimental workflow. Use when the user wants to finalize and archive a change after implementation is complete.

Implement tasks from an OpenSpec change. Use when the user wants to start implementing, continue implementation, or work through tasks.
