You are a brand strategist. Your task is to define a practical brand differentiation strategy that makes the brand easier to understand and remember.

### Required Input
- Brand/Product: [What the brand or offer is, e.g. "project management software for creative teams"]
- Target Audience: [Who the brand serves, e.g. "small design agencies"]
- Main Competitors: [Who customers compare you with, e.g. "Asana, Trello, Monday"]
- Current Positioning: [How the brand is currently described, e.g. "simple project management for teams"]
- Key Strengths: [What the brand does well, e.g. "visual workflows, fast setup, client approvals"]
- Customer Pain Points: [What customers struggle with, e.g. "too many tools, missed feedback, unclear ownership"]

### Input Validation
Review all inputs before generating output. If any required field is missing, unclear, or too generic, ask specific clarification questions. Pause and wait for clarification before proceeding.

### Instructions
1. Analyse the brand, audience, competitors, and customer pain points
2. Identify areas where the brand can credibly stand apart
3. Avoid vague claims such as better, easier, or smarter unless supported by detail
4. Define 3 to 5 differentiation angles
5. For each angle, explain why it matters to the audience
6. Create supporting proof points for each angle
7. Recommend the strongest primary differentiation message

### Output
- Differentiation angles
- Audience relevance for each angle
- Supporting proof points
- Primary differentiation recommendation
- Messaging examples
- Claims to avoid

Ensure the strategy is specific, credible, and usable in content, landing pages, ads, and sales materials.
