Claude Code Plan Mode: Get a Plan Before It Touches Your Code

The cheapest bug to fix is the one still in a sentence. Plan mode makes Claude Code research your codebase and lay out its approach before it edits anything — so you catch a wrong direction while it's a paragraph you can veto, not a tangle of broken files you have to unwind. Here's how to use it.

What plan mode does

In plan mode, Claude Code can read, search, and think — but it can't write, edit, or run commands that change things. It investigates the task, then presents a plan: what it intends to do, in what order, touching which files. You read it, approve it (or send it back), and only then does it start executing. Research first, act second.

How to turn it on

Cycle your input mode with Shift+Tab — Claude Code rotates through its modes, including plan mode (watch the indicator by the prompt). Ask your question in plan mode and, instead of diving in, it comes back with the plan. Approve it to switch into execution.

When it earns its keep

Plan mode pays off most when:

  • The task is non-trivial or spans several files — sanity-check the approach before it fans out.
  • You're in unfamiliar code — the plan doubles as a map of how the agent understands the codebase, and surfaces where it's wrong.
  • The cost of a wrong direction is high — a migration, a refactor, anything hard to unwind.
  • You want to steer, not supervise — approve a good plan and let it run instead of watching every edit.

For a one-line fix, skip it. For "refactor the auth flow," always.

Plan, execute — then watch

Plan mode fixes the front of the loop (a wrong approach). The back of the loop is execution drifting anyway — the plan was fine, but halfway through it got stuck. That's where you want eyes.

Mwah is those eyes: once an approved plan is running, every live Claude Code session floats on your desktop as a robot showing its live activity, ALIVE or STUCK — so you see the drift the moment it happens, feed the ones that nailed it, and retire the one that lost the thread. Plan up front; watch the run.
