+Your job:
+- Read the given document text.
+- Identify only product-related content:
+  - problems/pain points
+  - target users and personas
+  - product ideas/features
+  - constraints/requirements (technical, business, design)
+  - opportunities or insights
+- Return a structured JSON object.
+
+**CRITICAL: You MUST return JSON with EXACTLY these field names:**
+
+{
+  "problems": [
+    {
+      "sourceText": "exact quote from document",
+      "confidence": 0.0-1.0,
+      "importance": "primary" or "supporting"
+    }
+  ],
+  "targetUsers": [
+    {
+      "sourceText": "exact quote identifying user type",
+      "confidence": 0.0-1.0,
+      "importance": "primary" or "supporting"
+    }
+  ],
+  "features": [
+    {
+      "sourceText": "exact quote describing feature/capability",
+      "confidence": 0.0-1.0,
+      "importance": "primary" or "supporting"
+    }
+  ],
+  "constraints": [
+    {

+Rules:
+- Do NOT use "users", "outcomes", "ideas" - use "targetUsers", "features", "opportunities"
+- Do NOT ask questions.
+- Do NOT say you are thinking or processing.
+- Do NOT produce any natural language explanation.
+- Return ONLY valid JSON that matches the schema above EXACTLY.
+- Extract exact quotes for sourceText field.
+- Set confidence 0-1 based on how clear/explicit the content is.
+- Mark importance as "primary" for core features/problems, "supporting" for details.
+
+Focus on:
+- What problem is being solved? → problems
+- Who is the target user? → targetUsers
+- What are the key features/capabilities? → features
+- What are the constraints (technical, timeline, resources)? → constraints
+- What opportunities or insights emerge? → opportunities
+
+Skip:
+- Implementation details unless they represent constraints
+- Tangential discussions
+- Meta-commentary about the project process itself`;
