AO resolves aider from your machine and leaves model credentials to Aider's normal configuration.
ao agent ls --refresh
ao spawn --project my-app --name aider-task --agent aider --mode tui
Aider is currently Terminal UI-only. It does not have an AO structured Chat driver, so --mode chat is rejected explicitly.
Use project agentConfig and environment settings for supported model/permission overrides. Agent adapters are compiled into AO; there is no separate Aider plugin package or YAML plugin block.
