Agent "fleet" control surfaces are becoming their own tool category.

Beyond Yegge's Gas Town, Superset ("run an army of Claude Code, Codex"), agent-of-empires, and LobeHub's "Chief Agent Operator" all target managing many concurrent agents across harnesses, increasingly from mobile. The emerging UX problem is monitoring and steering dozens of parallel agents at once. This is worth tracking not because any one tool has won, but because the category itself just appeared, and category births are where the next default gets decided.
