One Chat, Two Powers: Operating Claude Code and Codex Together

Developers working with multiple AI coding assistants face constant friction from interface switching, which fragments focus and wastes time. This solution elegantly separates 'direct runtime' work—where messages go straight to the active AI—from 'assistant-mediated' work, allowing both Claude Code and Codex to coexist in one chat window. By introducing simple command-based mode switching (/cligate and /runtime), it removes the cognitive load of tool selection while maintaining explicit control over which AI handles each task.
