description	Generate multiple radically different interface designs for a module using parallel sub-agents. Use when user wants to design an API, explore interface options, compare module shapes, or mentions "design it twice".

Design an Interface

Generate multiple radically different interface designs before choosing one.

Workflow

1. Gather requirements:
   • what problem the module solves
   • who calls it
   • key operations
   • constraints
   • what should be hidden vs exposed
2. Produce at least 3 radically different designs.
3. For each design, include:
   • interface signature
   • usage example
   • what complexity it hides
   • trade-offs
4. Compare designs in prose.
5. Synthesize a recommended direction, possibly combining ideas.

Evaluation criteria

• interface simplicity
• general-purpose vs specialized
• implementation efficiency
• module depth
• ease of correct use

Do not jump straight to implementation.
