Agent WranglersWorking in small steps Required
Plan before the agent writes code
For any change beyond a few lines, have the agent read the relevant code and write a plan before it edits anything.
How to do it
Use the agent's plan mode, or ask for a plan and say not to change files yet. The plan names the files to change, the approach and the risks. Correct the plan, then let the agent build it. A wrong plan costs a minute to fix, and wrong code costs an hour.
How to check
Every non-trivial change in the history starts from a written plan, such as one in the task, the pull request or the session log.
