Multi-harness control plane for Claude Code, Codex, Cursor, and OpenCode: quota-aware rotation across multiple Claude/Codex subscriptions, shared thread context, and cross-model review.

Use Cursor CLI from Claude Code to delegate coding tasks to Composer 2.5+ and other Cursor models.

Manage and switch between multiple Claude Code (and other AI coding tool) profiles/accounts locally — isolated config dirs, per-account email, one-command switching.
