description	Generate multiple radically different interface designs for a module. Use when the user wants API options, module shapes, or says "design it twice".

Design An Interface

Goal: do not stop at the first design.

Workflow

1. Gather requirements:

• problem
• callers
• key operations
• constraints
• what should stay hidden

2. Spawn 3+ parallel sub-agents. Force real divergence:

• minimal interface
• flexible interface
• common-case optimized
• paradigm-inspired, if useful

Each design must include:

• interface signature
• usage example
• hidden complexity
• tradeoffs

3. Present each design separately.

4. Compare in prose:

• simplicity
• generality
• implementation leverage
• module depth
• ease of correct use

5. Recommend one design or a hybrid.

Rules

• Do not let designs collapse into variants of the same idea.
• Do not implement.
• Judge interface quality, not implementation effort.
