Exciting to see @OpenCode 2.0 ship! is a rewrite, not a point release. Here are the highlights.

Code Mode: the agent writes one short JavaScript script that chains tool calls, instead of separate round trips. MCP servers and @OpenAPISpec endpoints become callable functions. I want to try it on workflows that hit several MCP servers in a row.

Chaining calls saves round trips; partial failures still need receipts per server, not one final result.

Always-on local server: one background process that the TUI, web interface and desktop app all connect to. Scripts can discover it through the client package, and /pair exposes it to other hosts.

Background tasks: subagents and shell commands can run in the background, and ctrl+b moves running foreground work there. Useful for long test runs while you keep working.
