How does this skill interact with my existing code?

It performs parallel research across your local backend and frontend directories to understand your current architecture before drafting new specifications.

Does it generate implementation code or just documentation?

It focuses on the 'what' rather than the 'how,' producing high-level specifications and data contracts to ensure design clarity before coding begins.

Can I use it for UI and frontend features?

Yes, it includes a specific set of design principles for hierarchy, user actions, and cognitive load reduction specifically for frontend tasks.

Where are the resulting specification files stored?

The skill automatically outputs the final spec as a Markdown file in your project's designated specs directory, such as .specs/ or specs/.
