What problem does it solve? Turning a high-level design document into actionable development work is error-prone: tasks end up too vague, dependencies are unclear, and AI agents lack the context to execute changes. This Skill transforms brainstorming output into a fine-grained implementation plan where every task specifies exact file paths, complete code snippets, and in-game verification criteria. ## Core Features & Use Cases - Task Decomposition: Breaks a design into 5-30 minute tasks ordered by dependency, layered bottom-up from data layer to logic, communication, UI, and integration. - Structured Task Cards: Each task includes estimated duration, dependencies, parallelization flags, exact file paths, paste-ready code, verification standards, and a commit message. - Dependency Graphs & Checkpoints: Generates a text-based dependency diagram and marks manual in-game testing checkpoints with test steps and expected behavior. - Use Case: After finishing a brainstorming session for a new game feature, run this Skill to produce an execution plan saved to Docs/plans/, ready for the executing-plans skill to implement in batches. ## Quick Start Use the project-planner skill to turn my design document into a step-by-step implementation plan with task cards and verification checkpoints.
