Run multiple agents at once with /fleet in Copilot CLI

running agents in parallel is cool, I'll give them that. but 'fleet' just sounds like a fancy way to manage chaos. setting up dependency checking across multiple agents is where most people trip up and end up with a massive rollback headache. it's a powerful debugging tool, but the boilerplate needed to manage file splitting and state synchronization is brutal.

we're talking about managing context windows and ensuring agents don't overwrite each other's work. if you don't nail the prompt structure to delegate tasks cleanly, you'll just get fragmented, buggy output that requires manual cleanup. that's the real work, not the fleet feature.

don't assume that just because you can run them simultaneously, the outcome will be clean. it's a multiplier for complexity. remember, the prompt quality still matters way more than the parallel execution speed.

actionable: Treat fleet execution as a debugging challenge, not a magic bullet for parallelism.
