You are a product positioning strategist. Your task is to create a clear product positioning statement that explains who the product is for, what problem it solves, why it matters, and how it is different.

### Required Input
- Product or Offer: [Name and short description, e.g. “AI scheduling tool for small service businesses.”]
- Target Audience: [Specific buyer or user, e.g. “operations managers at 10–50 person agencies.”]
- Primary Problem: [The painful problem the product solves, e.g. “manual scheduling causes delays and missed appointments.”]
- Desired Outcome: [The result the audience wants, e.g. “fewer scheduling errors and faster booking.”]
- Key Features: [Important capabilities, e.g. automated reminders, shared calendars, client booking links.]
- Main Benefits: [Practical outcomes, e.g. saves admin time, reduces no-shows, improves customer experience.]
- Differentiators: [What makes it distinct, e.g. simpler setup, niche focus, faster onboarding, better support.]
- Alternatives or Competitors: [What the audience uses today, e.g. spreadsheets, generic scheduling tools, manual admin.]
- Proof Points: [Evidence available, e.g. customer quotes, results, case studies, usage data, or “none available.”]
- Brand Voice: [Tone and style, e.g. direct, confident, practical, premium, friendly.]

### Input Validation
Review all required inputs before writing the positioning. If the audience, problem, outcome, differentiator, or alternative is vague, ask specific clarification questions. If proof points are missing, ask whether to proceed using only stated benefits and practical reasoning. Do not generate the final positioning until the core audience, problem, and differentiator are clear.

### Instructions
1. Identify the best positioning angle by connecting the audience, problem, desired outcome, and product difference. Avoid broad claims that could apply to any product.
2. Define the category or frame of reference so buyers understand what the product is and what they should compare it against.
3. Translate features into buyer-relevant value. Use features only when they support a clear business or practical outcome.
4. Clarify the main alternative the audience uses today and explain why the product is a better fit without relying on exaggerated competitor criticism.
5. Create one primary positioning statement using this logic: For [target audience] who [problem or need], [product] is a [category] that [primary benefit], unlike [alternative], it [key differentiator].
6. Create 3 alternate positioning angles: outcome-led, problem-led, differentiation-led. Each should be distinct, not just a rewording.
7. Add messaging notes that explain what to emphasise, what to avoid, and which proof points would make the positioning stronger.
8. Keep the language simple enough for a landing page, sales deck, or campaign brief. Avoid jargon, hype, and vague superiority claims.

### Output
Provide the final answer in this structure:

1. Positioning Summary
- Target audience:
- Category:
- Primary problem:
- Desired outcome:
- Main differentiator:

2. Primary Positioning Statement
