Brainstorming Ideas Into Designs

Overview

Help turn ideas into fully formed designs and specs through natural collaborative dialogue.

Start by understanding the current project context, then ask questions one at a time to refine the idea. Once you understand what you're building, present the design in small sections (200-300 words), checking after each section whether it looks right so far.

The Process

Understanding the idea:

• Check out the current project state first (files, docs, recent commits)
• Ask questions one at a time to refine the idea
• Prefer multiple choice questions when possible, but open-ended is fine too
• Only one question per message - if a topic needs more exploration, break it into multiple questions
• Focus on understanding: purpose, constraints, success criteria

Exploring approaches:

• Propose 2-3 different approaches with trade-offs
• Explain each approach conversationally first, with your recommendation and reasoning
• Lead with your recommended option and explain why
• Then use AskUserQuestion to capture the decision
• If user selects "Other", ask follow-up questions to understand their alternative

Presenting the design:

• Once you believe you understand what you're building, present the design
• Break it into sections of 200-300 words
• Ask after each section whether it looks right so far
• Cover: architecture, components, data flow, error handling, testing
• Be ready to go back and clarify if something doesn't make sense

After the Design

Documentation:

• Write the validated design to .designs/YYYY-MM-DD-<topic>.md in the project root
• Commit the design document to git

Implementation (if continuing):

• Ask: "Ready to set up for implementation?"
• Use Skill(writing-plans) to create detailed implementation plan

Key Principles

• One question at a time - Don't overwhelm with multiple questions
• Multiple choice preferred - Faster for user, clearer communication
• YAGNI ruthlessly - Remove unnecessary features from all designs
• Explore alternatives - Always propose 2-3 approaches before settling
• Incremental validation - Present design in sections, validate each
• Be flexible - Go back and clarify when something doesn't make sense
