AO resolves your local opencode executable and reuses its authentication.

ao agent ls --refresh
ao spawn --project my-app --name opencode-task --agent opencode --mode chat

OpenCode can run as its native Terminal UI or through its native ACP interface in structured Chat. Chat history is persisted by AO as a durable, paged conversation projection while provider conversation identity is retained for continuity.

OpenCode is also a shipped reviewer harness. Reviewer configuration is independent from the worker harness; inspect project settings and ao review --help for the current review workflow.
