Reviewing a pull request from the diff alone misses what it actually affects. A two-line change to a shared utility can break a dozen callers across the codebase. This guide shows you how to map the full impact of any PR before you approve it.

​
Before you begin

  • Your repository is connected and indexed in Potpie (quickstart)
  • You have a pull request open that you want to review

​
Run the analysis

1

Open Ask on your codebase

Go to Potpie → Ask and select your repository.
2

Ask about the PR changes

Describe what the PR modifies and ask what it affects:
What does changing the UserService.updateProfile method affect across the codebase?
Ask traverses the knowledge graph from every modified function outward, mapping all callers, dependents, and transitive effects.
3

Review the impact map

Ask returns:
  • Every function, class, and module that depends on the changed code
  • Each call site with its exact file path and line number
  • Areas of the codebase most likely to regress from this change

​
Results

Once you have the impact map, you have two paths: Approve with confidence by using the file paths and line numbers to verify each affected call site is handled correctly in the PR diff. If any affected path looks risky, hand off to Debug by opening a Debug conversation and tracing the code path to verify no regression was introduced.
