Decomposing architectural plans into vertical slices breaks high-level designs into discrete end-to-end tasks, ensuring full-stack ownership and parallel execution. Each slice covers types, tests, implementation, and wiring owned by a single worker.

The dual-export anti-pattern occurs when workers lack ownership of full production code paths, causing fragmented development. Vertical slice decomposition solves this by assigning end-to-end task ownership to maintain clear accountability during implementation.

Integrating TDD into task planning uses a layer-cake approach where tests define contracts and implementation follows. This enforces high-quality, verifiable code by generating tasks that maintain end-to-end integrity for each feature.

Configuring review-cycle budgeting for task decomposition is supported by requesting a review-effort budget when generating the task list. This satisfies requirements for clear integration point documentation and TDD-based development.

Vertical slice decomposition operates independently without external dependencies, generating parallelizable tasks directly from ratified plans. It requires no prerequisite tools to break plans into discrete end-to-end implementation slices.

Fragmented development occurs during the transition from architectural plans to execution when tasks lack full-stack ownership. Decomposing plans into vertical slices prevents this by ensuring each worker owns complete production code paths end-to-end.
