Overview

Xerxes is a command-line AI agent that transforms natural language into DevOps operations. Unlike traditional tools with predefined commands, Xerxes uses free-form thinking to execute any command supported by your installed CLI tools (AWS, GCP, Kubernetes, Docker).

Features

Core Capabilities

• Unrestricted CLI Access: Execute ANY command from AWS CLI, gcloud, kubectl, or docker
• Free-Form Thinking: LLM reasons about your request and forms optimal commands
• Interactive Approval: See command + reasoning before execution
  • [R]un - Execute this command
  • [S]kip - Skip and continue
  • [A]lways - Auto-approve for session
• Bring Your Own Key (BYOK): Use your own Vertex AI credentials
• Multi-Cloud Support: AWS, GCP, Kubernetes, Docker in one interface
• Safety Mechanisms: Automatic detection of destructive operations
