Trunk-based development is a mainline-first workflow where developers integrate small, atomic commits into the main branch frequently. This rapid integration reduces long-lived branch divergence and minimizes merge conflicts.

Write atomic commits by making small, self-contained changes focused on a single task. Pair these atomic commits with descriptive messages to improve traceability and ensure the main branch remains deployable.

The best way to migrate to a mainline-first workflow is aligning the team on trunk-based development, enforcing disciplined branching patterns, and making small, frequent commits to main for predictable releases.

Yes, trunk-based development supports rapid integration by using short-lived branches for code reviews. Frequent integration of atomic commits into the main branch keeps the project history clean and deployable.

You should avoid trunk-based development if your team cannot commit to frequent integration or lacks the discipline for atomic commits, as long-lived feature work will create merge conflicts and break the mainline.

Descriptive commit messages are needed for trunk-based development because they provide essential traceability for atomic commits. They help teams track rapid integration changes and maintain a clean project history.
