42 The Code Review service and the local [`/code-review` command](/docs/en/code-review-local) are two separate tools, and they read different files. The service reads both `CLAUDE.md` and `REVIEW.md`. The `/code-review` command, which you run inside a Claude Code session on your own machine, reads your `CLAUDE.md` files and not `REVIEW.md`. Put guidance you want applied in both places in `CLAUDE.md`, and keep `REVIEW.md` for rules specific to pull request review.
