Claude Code adds effort control and /usage usage details
Claude Code now supports typing ultrathink in a message to raise the effort of a single turn to xhigh, and allows specifying a separate effort level for subagents. The CLI's /usage now explains in plain language what is consuming your quota, and if a quick fix is available, you can press f to apply it directly.
Body
You also get a bit more control over Claude's effort.
Typing ultrathink in a message now bumps effort to xhigh for just that one turn, so you can think harder on one problem without changing your setting for the whole session.
You can now also tell Claude which effort level to run a subagent at. If your session is on high but you want the subagents for a task on medium, just ask!
And /usage in the CLI now tells you in plain words what's using up your limits. If there's a quick fix, you can press f to apply it right there.
