Spotify engineers described shunt, a Claude Code plugin that routes large-file reading and predictable code generation through Portal's AiKA modes, using Gemini 2.5 Flash in the examples. The author reported mean bulk-read token savings of about 90% in tests on a Java monorepo; the modes are public and callable through Portal. The source says the system does not delegate editing or reasoning, and delegated calls typically add 10-30 seconds of latency.
