Starting Compare Mode
Compare Mode is started from the New Session flow within a project, not from the top-level navigation.
Compare Mode isn't a top-level destination in AgentDock's navigation — it's started from the New Session flow within a project, alongside the option to start a normal single-agent session.
Starting a comparison
From an open workspace, start a new session and choose the Compare option instead of a single agent. AgentDock then walks you into adding agents to the comparison.
