What problem does it solve? Turning a spec-driven development (SDD) proposal and design into concrete, ordered implementation work is error-prone and often skipped. This Skill converts the proposal, specs, and design artifacts into a structured tasks.md with dependency-ordered phases, verifiable checklist items, and a review workload forecast. ## Core Features & Use Cases - Phased Task Breakdown: Produces tasks.md organized into Foundation, Core Implementation, Integration, Testing, and Cleanup phases with hierarchical numbering. - Review Workload Forecast: Estimates changed-line risk against a 400-line review budget and recommends chained or stacked PR splits with rollback boundaries. - Multi-Mode Persistence: Supports engram, openspec, hybrid, and none artifact store modes, reading dependencies and persisting results accordingly. - Use Case: After an orchestrator completes SDD proposal and design phases for a change, this Skill produces the actionable task list that the implementation phase (sdd-apply) executes, including RED-test tasks for every applicable threat-matrix case. ## Quick Start Ask the orchestrator to run task planning for your approved SDD change so it delegates to the sdd-tasks sub-agent and produces a tasks.md breakdown.
