Use Case: Code Ownership

Code ownership that stays accurate — automatically

Most teams let their CODEOWNERS files drift for weeks. Files change hands, engineers leave, new repos appear without owners. Koalr syncs and enforces CODEOWNERS in real time.

Why CODEOWNERS enforcement fails at scale

✗CODEOWNERS files go stale the moment an engineer leaves or changes teams

✗Repos get created without owners — nobody knows who to page during an incident

✗PRs merge without required reviewers because nobody checks CODEOWNERS manually

✗There's no way to know which paths have no coverage until something breaks

How Koalr enforces code ownership

Six integrated mechanisms that keep CODEOWNERS accurate and enforced without manual review.

Auto-sync on every push

When a CODEOWNERS file changes in any repo, Koalr detects it via GitHub push webhook and syncs the new ownership rules within seconds.

Daily drift detection

A daily cron checks every repo's CODEOWNERS file against the database. Divergence triggers a Slack alert with a diff of what changed.

Slack notifications

When ownership gaps are detected — missing owners, repo with no CODEOWNERS file, or owner no longer in the org — the relevant team channel gets a Block Kit notification.

GitHub Check Run enforcement

Enable enforcement mode and Koalr posts a check on every PR. PRs touching files without a required reviewer get a failing check that blocks merge.

Coverage gap report

See exactly which paths in your repos have no CODEOWNERS coverage — ranked by file churn and deploy frequency so you fix the highest-risk gaps first.

Ownership health score

A 0–100 composite score (letter grade A–F) covering ownership completeness, drift rate, review compliance, and coverage gap ratio.
