Code ownership

As explained in Automating API Delivery

A code owner is an individual or team designated to review and approve changes to specified files, file types, or directories in a version-controlled repository.

A pull request can pass API linting and breaking-change checks yet still need design judgment. Code ownership routes changes to specified files, file types, or directories to a designated individual or team for review. When approval is required, a PR touching those paths cannot merge without it. section 8.9 section 8.3

For API definition files and guide documentation, the API governance team can act as code owner. Its review helps catch consistency and standards issues that automated checks may miss. Code owners are notified when a PR needs their attention. section 8.9

To require code-owner review in the illustrated GitHub workflow:

  • Add a CODEOWNERS file at the repository root and assign the reviewer to the relevant path, such as chapter8/apis. Commit and merge the file. section 8.5.6
  • Give the reviewer repository access, then configure main-branch protection to require PRs, code-owner approval, and successful PR build and minimum-review-criteria status checks. section 8.5.6
  • Check that a PR changing the protected path requests code-owner review. A successful build alone does not satisfy the separate approval requirement. section 8.5.6

Keep ownership targeted. Requiring many reviewers outside the team making a change can delay approval; reserve external governance approval for API definitions that need it, and let teams review most other changes internally. Code-owner support depends on the hosting service and may require an add-on. section 8.9

How Automating API Delivery covers it

How deep it goes
Defines the approval rule and walks through CODEOWNERS and branch-protection setup, without detailing pattern syntax.
Examples
Uses a GitHub CODEOWNERS file assigning a reviewer to chapter8/apis, alongside required PR jobs.
What it assumes
Assumes a version-controlled repository with PRs and an existing CI/CD pipeline; introduces the code-owner feature.
What you can do after
Operate/configure code-owner approval alongside required PR status checks for selected API artifacts.
How it connects
Connects pull requests, API governance, branch protection, API linting, and breaking-change checks.
