WebSocket support

Agent workflows are getting longer and more dependent on fast back-and-forth between models, tools, and local environments, so the transport layer is getting an upgrade.

The next generation of traffic

Sleev now supports Responses-style WebSocket traffic in beta.

• WebSocket is supported with Codex CLI out of the box.
• OpenCode WebSocket support requires export OPENCODE_EXPERIMENTAL_WEBSOCKETS=true.

We will keep expanding provider coverage as more agent tools move to WebSocket-based transports.
