Claude Code 2.1.278: auto-mode safety checks no longer billed for API users
Claude Code 2.1.278 (Sept 19) defaults auto-mode safety classification to a free server-side check for Claude API, Enterprise, Bedrock, Vertex, Foundry, and gateway sessions when reachable; billed local fallback still applies if a proxy strips the fields. Build 2.1.277 also reads AGENTS.md when no CLAUDE.md exists (not yet on Bedrock, Vertex, or Foundry).
