What problem does it solve? Turning an agreed product goal into an ordered, recoverable set of development tasks is hard when work spans multiple modules, dependencies, and integration points. This Skill structures that transition so implementation starts from a verified, sequenced plan instead of ad-hoc edits. ## Core Features & Use Cases - Executable Work Decomposition: Gives every planned item an identity, concrete result, owning area, prerequisite IDs, acceptance reference, and current state. - Dependency-Aware Sequencing: Orders items by prerequisites and user value, selects one ready item, and preserves completed work and failed approaches when revising the plan. - Recovery and Continuity: Maintains branches, worktrees, checkpoints, and recovery details so the plan survives context switches and resumed sessions. - Use Case: You have an accepted feature spanning frontend, API contract, and database changes. Use this Skill to split it into vertical slices with clear ownership and verification, then begin implementation on the first ready item. ## Quick Start Ask Codex to break the accepted feature into an ordered development plan with dependencies, owners, and verification steps before writing any code.
