Claude Code 2.1.302: Pin Auto-Mode Models and Fix CI Defaults Oct 17, 2026

Show notes

Claude Code 2.1.302 adds CLAUDE_CODE_AUTO_MODE_MODEL, letting users on proxy, Bedrock, or Vertex setups choose the model used by the client-side auto-mode classifier. The episode also covers a breaking default for headless sessions—explicitly set --permission-mode auto in CI—as well as server-side auto-mode compaction and smaller updates to subagents, idle compaction, hooks, image handling, and plugin startup.

Claude Code 2.1.301 adds CLAUDE_CODE_RETRY_WATCHDOG_MAX_USAGE_LIMIT_WAIT_MS, letting CI jobs fail quickly or switch to a fallback model instead of idling through a distant quota reset. Learn how to set it alongside the general retry wait cap, where to scope the watchdog variables, and what “per API request turn” means. Also covered: richer OpenTelemetry tool-decision events, safer worktree cleanup, clearer Grep and Glob errors, and several usability fixes.
