Summary
Cloudflare released Agents SDK v0.12.4 with a cluster of reliability upgrades across agents, @cloudflare/ai-chat, @cloudflare/think, and @cloudflare/voice. The update improves chat recovery after disconnects, adds routing retries for transient Durable Object failures, introduces durable programmatic Think submissions, and adds connection control for voice agents.
What changed
Cloudflare shipped Agents SDK v0.12.4 with stronger recovery behavior for interrupted chats and tools, configurable routing retries, durable Think submissions, and voice-agent connection controls.
Why it matters
Long-running agents fail in messy ways: dropped sockets, interrupted streams, tool calls spanning restarts, and partial state recovery. This release shows Cloudflare focusing on the runtime reliability layer that increasingly separates serious agent infrastructure from demo-grade orchestration.
