Which Claude code review tool should I actually use?

Three reviewers ship inside Claude: a single-pass local /review, a cloud-sandbox multi-agent /ultrareview, and a GitHub App that runs on every PR. They cost different amounts, run in different places, and answer different questions. Here's the picking guide and the per-tool footguns.

How do I make Claude plan before it edits code?

Press Shift+Tab in the CLI until the input shows plan mode, or write 'do not edit yet, write a plan'. Plan mode holds source edits until you approve; reads and shell commands still run (with normal prompts). Approve only plans that list exact files, an explicit out-of-scope list, and a verification command.
