incremental-implementation

To prevent untested code changes from accumulating during software development, break feature work into small, testable slices. This approach maintains working code throughout development by enforcing verification checkpoints after every implementation slice.

The best way to maintain working code during multi-file feature development is enforcing scope discipline and verification checkpoints. By isolating changes and avoiding unnecessary abstractions, developers keep commits rollback-friendly and ensure continuous validation throughout the implementation workflow.

Adding verification checkpoints after every code change requires running type checks, linting, and tests immediately following each implementation slice. This continuous validation prevents large unverified implementations from accumulating and ensures each slice remains rollback-friendly.

Incremental implementation works effectively for bug fixes and multi-task plans by breaking them into small, testable slices. This process applies scope discipline and verification checkpoints to isolate changes and maintain working code throughout the workflow.

You should avoid building features in thin vertical slices when a project lacks clear scope boundaries or requires massive architectural changes upfront. Slice planning demands isolating changes into rollback-friendly commits, which fails if continuous validation cannot be enforced.
