What is the primary output of the plan skill?

It generates a structured markdown design document that includes high-level implementation approaches, component responsibilities, data models, and a requirements coverage matrix.

Where are the design documents saved?

Designs are saved to a feature-specific directory within the .specs/ folder, typically following the path .specs/{feature-name}/design.md.

Does this skill check my existing code?

Yes, it analyzes your current codebase to ensure the proposed design follows existing patterns, conventions, and integration points within your project.

How does this fit into the SDD workflow?

This is Phase 2 of the Spec-Driven Development workflow, occurring after a specification is created (Phase 1) and before the task breakdown (Phase 3) and implementation (Phase 4) begin.

Can I use this without manually providing a file path?

Yes, if no path is provided, the skill automatically searches the .specs/ directory for the most recent specifications to process.

Productivity & Workflow

Generates comprehensive implementation design documents from feature specifications to streamline the technical planning process.

This skill automates the transition from requirements to architecture by analyzing specifications and the existing codebase to create a detailed implementation plan. It helps developers maintain technical consistency by identifying necessary component modifications, defining data models, and mapping design choices back to functional requirements. By standardizing the design phase, it ensures that all edge cases are considered and that the resulting implementation aligns with the project's existing patterns, reducing architectural debt and improving code quality.
