Plan Mode vs Direct Execution

In Claude Code you constantly make one judgment call: plan first, or execute now?

Plan Mode lets Claude explore, read files, and propose a written plan that you approve before any edits land. Direct execution skips straight to making changes.

The skill isn't picking one forever. It's matching the mode to the size and clarity of the task. Big or ambiguous? Plan. Small and clear? Execute.

Plan Mode gives you four concrete benefits:

• Safe exploration — Claude reads and investigates without touching files.
• Approval gate — you review the proposed plan before edits happen.
• Approach comparison — when multiple solutions exist, you see them laid out.
• Architectural framing — design decisions surface early, not mid-edit.

Use it for large changes, multiple possible approaches, and architectural decisions where a wrong turn is expensive to unwind.
