What to expect from an ideal product

  1. Search across all repositories at once to find every instance of code that needs changing, even in codebases with thousands of repos
  2. Create and test code changes in isolated branches before applying them widely, reducing the risk of breaking production systems
  3. Track which changes succeeded or failed across different repositories and get detailed reports on what went wrong where
  4. Use batch operations to apply the same refactoring pattern to hundreds of files simultaneously instead of making changes one by one
  5. Verify that your automated changes work correctly by running tests and checks before merging, catching issues early in the process
