The big idea
Claude Code, Cursor Agent, and Manus all show you what they're 'thinking' — the plan, the next tool call, the reasoning. Most users zone out and only check the final result. Pros watch the trace and hit Ctrl-C the moment they see the agent heading the wrong way. The trace is your steering wheel.
Some examples
- Claude Code says 'I will now delete the test folder to start fresh' — you Ctrl-C and clarify.
- Cursor's agent panel says 'I'll use lodash for this' — you stop it and say 'we don't use lodash, use vanilla JS.'
- Manus shows 'opening browser to login.bank.com' — you stop it because it shouldn't be there.
- Copilot Workspace shows the planned diff — you spot a deleted import before approving.
Try it!
Run any agent for one task. Read every plan or 'thinking' line out loud. Catch one mistake before it happens.
