name	brainstorm
description	Guided construction project concept ideation — from zero idea to a structured project brief. Uses professional planning frameworks and construction industry best practices.
argument-hint	[building type or 'open' for fully open brainstorm]
user-invocable	true
allowed-tools	Read, Glob, Grep, Write, Edit, AskUserQuestion

When this skill is invoked:

1. Parse the argument for an optional building type hint (e.g., apartment, shopping mall, hospital). If open or no argument, start from scratch.

2. Check for existing work: Read design/architectural/project-brief.md if it exists.

3. Run through ideation phases interactively:

Phase 1: Discovery

• What is the purpose of this building?
• Who are the primary users/occupants?
• What is the site context (urban/suburban/rural, climate)?
• Budget range and timeline expectations?
• Sustainability goals?
• Any regulatory constraints known?

Phase 2: Concept Generation

Generate 3 distinct concepts with different approaches:

• Working Title
• Building Type and Program
• Design Approach (traditional, modern, sustainable, adaptive reuse)
• Structural System recommendation
• Estimated Size (gross SF)
• Estimated Budget Range
• Unique Value — what makes this project distinctive
• Biggest Risk

Phase 3: Design Principles

Define 3-5 design principles for the chosen concept.

Phase 4: Program Development

Outline key spaces, areas, and adjacencies.

Phase 5: Feasibility

• Structural system recommendation
• MEP complexity assessment
• Sustainability target recommendation
• Preliminary schedule estimate

4. Save to design/architectural/project-brief.md

5. Suggest next steps:

   • /setup-project-type to configure codes and standards
   • /map-systems to decompose into building systems
   • /design-system for per-system design documents
   • /feasibility-study for detailed feasibility analysis
   • /phase-plan new to plan the first phase
