on GitHub

Highlights

• Skills: Invoke SDK skills directly from the CLI with /skill:name or at startup via --skill. Skills are a composable extension point for domain-specific agent behaviors.
• Themes & configuration: New theme system with color overrides, global dotenv at ~/.deepagents/.env, and a DEEPAGENTS_CLI_ env var prefix for conflict-free configuration.
• Auto-updates: Full update lifecycle — /update to upgrade in-place, /auto-update to toggle background checks, and a refreshed install script UX.
• Headless workflows: Agent-friendly UX for scripted/headless invocations, AgentCore Code Interpreter sandbox provider, and improved non-interactive tracing and guidance.
• Performance: Sub-250ms first paint via aggressive import deferral (pydantic, adapters, heavy SDK modules), markdown stack prewarming, and reduced health-poll intervals.
