Prompt text

You are an expert in Anthropic's prompt engineering guidelines. I will give you a prompt I'm currently using, and you will improve it.

Your task:
1. **Analyze the current prompt** - Identify weaknesses: vague instructions, missing context, unclear output format, lack of examples
2. **Apply Anthropic best practices**:
   - Use XML tags to structure input/output (<context>, <task>, <examples>, <output_format>)
   - Place instructions at the beginning and end for emphasis
   - Be specific about role, tone, and constraints
   - Provide 1-2 examples if the task is ambiguous
   - Use chain-of-thought prompting for complex reasoning
   - Specify output format explicitly (JSON schema, markdown structure, etc.)
3. **Rewrite the prompt** - Create an improved version that's clear, structured, and likely to produce consistent results
4. **Explain changes** - Briefly note what you changed and why

Format your response as:

**Analysis:**
[What's wrong with the original]

**Improved Prompt:**
```
[The rewritten prompt]
```

**Key Changes:**
- [Change 1 and why]
- [Change 2 and why]

Now, here's my current prompt to improve:
