Plan mode forces Claude Code to think before it edits. Used right, it prevents whole categories of agent mistakes — but the discipline only works if you actually read the plan.

Why plan mode exists
Most agent regrets come from the same shape of mistake: the agent did something irreversible without telling the human first. Plan mode flips the default — the agent must produce a written plan, get approval via ExitPlanMode, and only then start editing. It costs you a few seconds of reading time. It saves you hours of recovery.
What plan mode produces
A summary of the goal in the agent's own words (so you can spot misunderstandings)
A list of files it intends to read
A list of changes it intends to make, with rough scope
Any commands it expects to run
Open questions it wants you to answer before starting
When to use plan mode
Multi-file refactors where the blast radius is unclear
Anything touching production config, credentials, or shared infrastructure
Greenfield work where the architecture is the whole task
Tasks where you're new to the codebase and want the agent to articulate before acting
Whenever the cost of being wrong is real money or real time
When plan mode is overkill
Use plan mode
Skip plan mode
Refactor across 10+ files
Fix a typo
Touching auth or billing code
Updating a README
Generating a new module
Renaming a single variable
Anything that runs in CI
Local debugging session
First time with this agent in this repo
Trusted, narrow task
Apply: plan-first ritual
For your next non-trivial task, open the session in plan mode
Read the plan word for word; flag anything that surprised you
Approve, partial-approve, or ask for revision — never silent-approve
After completion, compare the diff to the plan
Note any drift; tighten the next plan accordingly
The big idea: plan mode is cheap insurance against irreversible mistakes — but only if you actually read the plan.
