What problem does it solve? Turning a system design into an actionable development plan is error-prone: tasks end up too coarse, dependencies are unclear, and traceability back to requirements is lost. This Skill converts keel design and test-case documents into a structured task list where every task is testable, acceptable, and reviewable. ## Core Features & Use Cases - Layered Task Breakdown: Classifies tasks into four layers (core logic, API, UI, infrastructure) with risk-based review profiles (fast/guarded/audit) and TDD execution guidance per layer. - Requirement Traceability: Every task links back to feature IDs (F-XXX), acceptance criteria (AC-XXX), constraints (CON-XXX), and test cases (UT/IT/E2E-XXX), with a dependency graph and cycle-free ordering. - Incremental & Realign Modes: Appends or inserts tasks from feature/bugfix/insights flows, backfills design references for UI tasks, and upgrades existing task documents to newer spec versions without touching task status. - Use Case: After finishing system design and test cases for a new feature, run the Skill to produce 04-dev-tasks.md with 10+ TAR-compliant tasks, then hand them to the dev-workflow executor for TDD-based implementation. ## Quick Start Ask the assistant to split the completed system design into development tasks by running /dev-tasks, then confirm the generated task document before starting execution.
