When a team reorganizes, hand over each shared library with a written checklist covering the owner field, repository permissions, publish rights, secrets, alert routing and consumer notice. Do it before the old team disbands, because access and context both disappear quickly afterwards.
Why handovers fail
Teams hand over code and forget everything around it. The new owners can read the repository but cannot publish, do not receive vulnerability alerts, and do not know which consumers are fragile. The first security fix then waits for an access request.
The checklist
- Decide the new owning team. One team, agreed in writing by both managers.
- Update machine readable ownership. The CODEOWNERS file, the catalog owner field and the README. GitHub requires listed code owners to have write permission, and a listed team must be visible with write access, so verify that on a test pull request.
- Move permissions to the team. Repository admin, branch protection settings and package registry publish rights.
- Rotate secrets. Publish tokens, CI variables and signing keys held by individuals on the old team. Treat the move like an offboarding.
- Reroute alerts. Dependency alerts, scanner findings and registry notifications must reach the new team's queue.
- Transfer open work. Open issues, pending vulnerability exceptions and planned deprecations. An exception owned by a team that no longer exists is an audit finding waiting to happen.
- Walk through a release. The old maintainer drives the first release with the new team watching, then the reverse for the second.
- Notify consumers. One message with the new contact route and any pending changes.
- Confirm in thirty days. Check that the first alert was triaged by the new team.
What to hand over besides access
| Item | Example |
|---|---|
| Known quirks | A build flag, a flaky test, a consumer that pins an old version |
| Consumer map | Which services depend on it and which are critical |
| Debt list | Outdated dependencies and planned upgrades |
| History | Why risky decisions were made |
Who signs off
The outgoing and incoming managers sign off on the handover record. Keep it with the library, not in a chat thread.
Safeguard can help with the inventory side: its SBOM and dependency scanning shows which services pull in a given internal library, and you can run a free scan at gold.safeguard.sh/scan.
Quick check
How long should the old team stay available?
Plan for at least two releases or thirty days, whichever is longer, so context transfers through real work.
Do we need to rotate tokens even if nobody left?
Yes if they are tied to individuals who no longer own the library. The new team should hold credentials issued to its own group or role.
