Every pull request tells a story. The problem is finding the thread. During reviews, you’re left sifting through PR descriptions, comments, and code changes. This leads to even more scrolling, piecing things together, and, inevitably, losing the plot along the way.

What if there was a continuous path through the work—something closer to having an engineer walk you through their changes, step by step? Now there is. Today, we're excited to introduce Code Tours.

A new way to review code

Code Tours turn a pull request into a guided walkthrough of the proposed code changes. Instead of scrolling between the PR description and a scattered set of changes, you now can move through the code in a clear sequence, with full context in narrative form. 

Graphite makes this work by pulling together everything from the PR—the description, the conversations, the stack, and the code itself—and turning it into a structured readout. Instead of separating explanation from implementation, it brings them together in one artifact. The narrative lives alongside the diff, so you can move through a change without breaking context. The result: faster understanding, with less backtracking.

Code Tours are just getting started. We're shipping a series of fast-follows in the coming weeks to make them even more powerful:

• Visual artifacts. You'll be able to see the actual visual impact of a change.

• Test validation. Code Tours will surface the tests that validated the change.

Go deeper without leaving the PR

In addition to Code Tours, we’re also expanding Cursor Agent access to reviewers. Previously, only PR authors could use Cursor Agent to interact with their changes. Now, reviewers can spin up Cursor Agent directly to dig deeper—running scripts, executing tests, and making tool calls—all without leaving their review flow.

Code Tours are a step toward a review experience that keeps up with you—and preserves flow instead of breaking it. Give Code Tours a try on your next PR and let us know what you think.
