- Spotify's engineering blog introduces Portal: a plugin that routes bulk reading to a cheaper model so you avoid expensive read token costs, claiming a 90% cut in Claude Code costs.
- Setup: claude plugin marketplace add spotify/portal-ai-plugins, then install portal and shunt, and run /portal:setup in a new session to authenticate the Portal CLI.
- The portal plugin provides the CLI that shunt delegates through; bulk-reader and code-writer modes are public, forkable to customize worker models and instructions, with forks taking precedence automatically. Modes are reusable across projects, shareable with teams, and the plugin enforces routing.
