Cost Tracker

It breaks down what burns through tokens fast (file reads, spawning subagents, broad searches) and gives you rough budgets for different task types, like $0.50 for a bug fix or $5 for a refactor. The tool call budgets are especially handy since you can tell when you're halfway through your runway and should wrap up. Most useful if you're running lots of sessions or working on a tight budget and want to know where the money actually goes. The optimization list is practical stuff like reading files selectively and batching operations instead of spamming individual calls.
