OpenCode v2.2.3 adds a built-in Claude Agent provider for using a Claude Code login and its models

OpenCode v2.2.3, released Oct 30, adds a built-in Claude Agent provider: with Claude Code installed locally and `claude auth login` run, users select Claude Agent in /connect to use their Claude Code login and models. In March 2026, v1.3.0 removed OpenCode's built-in Anthropic OAuth login plugin following legal requests from Anthropic.

Why it matters
