Frequently asked questions about Code Review Tools

Real answers from real users, pulled straight from launch discussions, forums, and reviews.

  • Graphite offers a VS Code extension (plus a CLI) for local stacking, while its Reviewer runs in the cloud and attaches comments to PRs. That means you can get IDE-side workflows and repo-level automation.

    Typical integration patterns from these tools:

    • IDE plugin/extension (e.g., VS Code) for local review flows and quick feedback.
    • Repo/PR integrations (GitHub, Bitbucket, GitLab) so reviews run regardless of which editor teammates use — Cursor, Vim, Xcode, etc.

    If you want both local convenience and consistent PR enforcement, look for tools that provide an extension + repo integration.

  • Graphite Reviewer can handle large monorepos and very big PRs by pre-indexing your repo and using fast RAG-based lookups. The team reports LLM feedback returns in seconds and they don’t see noticeable slowdowns for the p95 of changes. Key takeaways:

    • Indexing: the repo is indexed asynchronously with no manual setup, so reviews use repo context automatically.
    • Performance: chained LLM queries and large-context prompts are used to keep reviews fast even on big PRs.
    • Workflow help: tools like Cubic add file grouping/ordering (backend → API → UI) to reduce jumpiness on huge PRs.

    These approaches improve speed and focus when reviewing massive changes.
