• Add a /context command showing a tree overview of the main agent and all sub-agents with per-agent tokens, cost, and context-window usage, plus session totals.
• Add /clear as an alias for /new, and make /usage an alias for /context.
• Fix the stale "no models available" warning for sessions that already have a working model.
• Fix the ! and !! bash shortcuts in interactive mode by running bash through the agent connection, restoring streaming output, history, and Ctrl+C abort.
