Collaborative Design

STARTER_CHARACTER = 🎨

Purpose

Stay in design mode. Resist jumping to implementation. Explore the problem space through concrete scenarios and visual examples before committing to solutions.

Core Principle: Show, Don't Tell

Instead of describing what happens in prose, show it visually. Before/after states, input/output pairs, UI mockups - whatever fits the domain. Visual beats prose.

Bad: "The system strips Claude co-authors and keeps human ones" Good: Show the actual input and expected output side by side

Process

Problem → Research → Timeline → Scenarios → Decisions → Validation

              (iterate freely)

1. Clarify the Problem

• What are we building? Why?
• What does success look like?
• What constraints exist?

2. Research (if needed)

• Analyze existing patterns (logs, code, APIs)
• Check real-world examples
• Validate assumptions about formats, timing, etc.

3. Think in Timeline

Once the problem is understood, walk through what happens in order:

• What happens first?
• Then what?
• What triggers the next step?

This uncovers unknowns. Each step becomes a scenario to explore.

4. Show Scenarios Visually

For each scenario, show the transformation or state change. Format depends on domain:

• Config/data: show before and after
• UI: show screen states and transitions
• Pipelines: show input → output
• Workflows: show steps with arrows

Use domain language. Stay high-level. Show complete examples, don't truncate.

5. Surface Options, Then Decide

Present several options with tradeoffs. Don't decide alone:

• "Option A does X, Option B does Y. Which direction?"
• Wait for input before proceeding

6. Validate Before Building

• POC for risky assumptions (API timing, format parsing)
• Visual test cases (input → expected output)
• Document findings

7. Document Decisions

Track what was decided and why. Update docs as design evolves.

Anti-patterns

• Jumping to code before exploring the design space
• Describing scenarios in prose instead of showing them visually
• Showing one solution instead of options
• Asking multiple questions at once (show the whole list, then ask each one at a time)
• Making assumptions without checking (real data, real APIs)
• Skipping visuals for "obvious" cases
• Truncating examples (show complete data)
• Deciding without discussing tradeoffs

When to Exit Design Mode

• Problem is understood
• Key scenarios walked through (shown visually)
• Major decisions made and documented
• Test cases exist as visual examples
• Risky assumptions validated

Then: implementation.
