Hooks are commands or checks Claude Code runs automatically at set points.\n\n- A side request, a short extra request Claude Code makes beside your main conversation, is retried once on the default model if the gateway refuses it with error 400, 403 or 404.\n\n- The check for whether a small, fast model is configured can now also pass for the gateway provider.\n\nAgent hooks also now receive a filtered set of your permission rules.\n\n**Why**\n\nGateway users who have not mapped a Haiku-class model would otherwise see hooks and side requests fail.\n\n- Area: LLM Gateway\n- Tier: You'll notice\n- Useful: 2\/5\n- Signal: 1\/5\n- Scope: org\n- Heads-up: no"}
