Agnostic Cluster Refactor Skill for Antigrafity CLI: Building an AI Agent that Migrates Apps from AWS to GKE (Subagents, HITL Gate & Workload Identity)

Short summary

Author documents building an AI agent for the Antigravity CLI that automatically migrates Python applications from AWS to Google Kubernetes Engine, handling code refactoring (boto3→GCS), infrastructure generation, and credential migration through parallel subagents with mandatory human approval gates. The agent operates in isolated Git worktrees to prevent production pollution. Technical deep-dive combining agent orchestration, Kubernetes patterns, and cloud-vendor abstraction for infrastructure teams.

• •AI agent automatically refactors AWS-coupled code (boto3) to cloud-agnostic GCS patterns across entire codebase
• •Subagent architecture with HITL gates and isolated worktrees prevents unvetted mutations from reaching production
• •Practical patterns for migrating workloads from AWS to GKE with semantic understanding rather than simple string replacement
