Google expands Conductor with portable plugin support for Antigravity

Google has evolved Conductor from a Gemini CLI extension into a portable plugin that supports Antigravity, Claude, and other AI coding environments.

The update replaces rigid command-based workflows with a conversational interface that automatically manages project specifications, implementation plans, and development context through persistent Markdown files.

By packaging skills, rules, MCP servers, and hooks into a single plugin, Conductor enables developers to move between AI coding tools without losing project state. Google also reports improved performance on complex TerminalBench tasks, helping teams adopt spec-driven development while maintaining a version-controlled source of truth for software projects.
