What problem does it solve?
This Skill helps Phase Leads validate a large phase before real implementation by running a learning-only Sprint 0 that exposes hidden complexity, coordination gaps, and user experience issues early.
Core Features & Use Cases
- Exploratory trial branch setup: Creates the dedicated Sprint 0 worktree and prompt structure for a phase-level trial pass.
- Learning-only implementation: Guides an implementer to attempt the full planned scope across all intended sprints without producing merge-ready output.
- Evidence capture and refinement: Produces friction logs, test results, regression guidance, and optional UX review artifacts that inform Sprint 1-N prompt revisions.
- Use case: A Phase Lead uses this Skill when a multi-sprint feature set is uncertain and needs a realistic trial run before committing the team to detailed implementation.
Quick Start
Ask the AI to set up and execute Sprint 0 for the current phase, then collect the friction log, testing results, and any UX review deliverables for prompt refinement.
