What problem does it solve?

Teams often struggle to translate vague user needs into concrete, testable work that delivers observable value in small, verifiable increments. This skill provides a disciplined approach to break down work into vertical cycles, ensuring each increment is fully testable and demonstrable.

Core Features & Use Cases

• Transforms user stories into independent vertical cycles (foundation and feature cycles) with clear boundaries.
• Provides standardized cycle templates and task formats, including explicit file paths, acceptance criteria, and verification checkpoints.
• Enforces test-first discipline at the cycle and task level, guiding red/green/refactor workflows and ensuring traceability from spec to implementation.
• Includes references and heuristics for slice identification and cycle structure to aid consistent practice across teams.

Quick Start

Provide a vertical-slice plan from user stories using test-first cycles and cycle templates.
