name	idea-expander
description	Use when the user has a rough product or feature idea and wants it expanded into user stories, workflows, open questions, and implementation considerations.

Expand a feature idea into a comprehensive plan. Follow these steps:

1. Brainstorm — Expand the idea considering core functionality, user roles, integration points, error states, technical constraints, and UI/UX.

2. Clarify — If details are ambiguous, batch all questions and call add-pending-questions with JSON arguments. Each argument has a question field and optional options array. After calling it, stop and wait for answers. Only ask questions that affect feature design or implementation.

3. Write the Expansion — Produce a comprehensive expansion with these sections: Overview, User Stories, User Flows, Functional Requirements, Non-Functional Requirements, Edge Cases & Error Handling, Technical Considerations, and Open Questions. Be specific and concrete.

Output to a markdown file with an auto-derived UPPER_CASE slug name (e.g. FEATURE-IDEA.md). The report must include the original idea, all clarifications and answers, and all sections.
