What problem does it solve? Teams lose alignment when project goals, scope, and milestones live in scattered documents or verbal agreements. This Skill establishes PROJECT.md as a single source of truth, keeping planning artifacts synchronized with actual development work. ## Core Features & Use Cases - PROJECT.md-First Planning: Creates and updates PROJECT.md files defining goals, scope, constraints, and explicit non-goals. - Cycle & Sprint Planning: Plans delivery-oriented cycles with cool-down periods using appetite-based betting instead of time estimates, following Linear Method and Shape Up practices. - Async Execution & Review: Supports asynchronous standups, issue triage workflows, architecture decision records (ADRs), demos, and retrospectives. - Use Case: When starting a new feature cycle, ask the agent to draft a PROJECT.md with SMART goals and non-goals, then validate each sprint's work against it during review checkpoints. ## Quick Start Create a PROJECT.md for my current project with goals, scope, non-goals, and a milestone roadmap for the next cycle.
