7: Plan First, Then Implement
One of the safest workflows is to separate investigation and planning from implementation. First ask Claude Code to read the specification, inspect the relevant code, and explain how the current system works. Next ask it to create a short plan containing the files it expects to change, the main implementation steps, tests, and possible risks. Review the plan before implementation because correcting one wrong assumption is much cheaper than correcting a large patch. Once the plan is approved, ask Claude Code to implement it without expanding the scope. After implementation, ask it to compare the result with the specification and report anything missing. This gives junior developers a clear way to supervise the AI and understand why particular files are being changed. Manual development benefits from the same planning discipline, but Claude Code makes the investigation and mechanical work much faster.
