## TL;DR

CODEOWNERS and review rules help agents route risky edits to the people or teams responsible for the affected paths.

## Core Explanation

Code agents should inspect ownership metadata before touching high-impact files. CODEOWNERS entries, branch protections, required reviewers, and team ownership rules can explain why a pull request is blocked or why an edit needs a specific reviewer.

This is also safety evidence. An agent that changes security, billing, migration, or generated-code paths should identify the owning team and review rule rather than treating all repository files as equally editable.
