Portal by Spotify cut my Claude Code token usage by 90%

Portal by Spotify reduces Claude Code token consumption by routing repetitive I/O and boilerplate tasks to inexpensive Gemini 2.5 Flash agents called “modes.” Two declarative modes—bulk-reader for large file reads and code-writer for pattern-based code generation—handle these tasks via the Portal CLI, freeing the frontier model for complex reasoning and cutting token costs up to 90%.
