const longReasoningPrompt = `Please transform the following original reasoning process into a structured flowchart:
'''

'''
Requirements:
0. Create a visually balanced and aesthetically pleasing diagram
1. Structure each node as: [Step Name]: [Concise Summary of Reasoning]
- Keep node text simple and enclose in double quotes inside brackets like: A["Step Name: Reasoning"]
- Example: A["Problem Framing: Define the question"]
2. Support multiple reasoning structures:
- Linear reasoning: Sequential steps leading directly to a conclusion
- Tree reasoning: Branching paths exploring multiple possibilities
- Reflective reasoning: Loops that revisit and refine earlier conclusions
- Not limited to the structures above
3. Flowchart syntax guidance:
- Start with: flowchart TD
- Node definition: letter["text content"]
- Connection definition: A --> B
- Conditional branch: A -->|condition| B
4. When analyzing the reasoning:
- Preserve the logical structure of the original reasoning
- Identify implicit steps that connect explicit reasoning
- Highlight areas where reflection led to revised conclusions
- Maintain proper causal relationships between nodes
- When showing alternative methods or different solution attempts, use a tree-like structure with branches to clearly visualize parallel thinking paths
5. Include these specific style classes in your Mermaid flowchart:
- classDef default fill:#f9f9f9,stroke:#333,stroke-width:2px;
- classDef question fill:#e3f2fd,stroke:#1976d2,stroke-width:2px;
- classDef answer fill:#d4edda,stroke:#28a745,stroke-width:2px;

6. Apply styling to specific node types:
- The first node (starting point) should use class "question"
- The final conclusion/answer node and any significant intermediate results should use class "answer"
- Any sub-questions or question refinements should also use class "question"
- Nodes that involve refinement, reflection, revision, or error correction should use class "refinement". Ensure each refinement node has both incoming arrows from preceding steps and outgoing arrows to subsequent steps, maintaining the full flow of the reasoning process while also creating proper feedback loops.
- Nodes that represent key insights, breakthrough moments, or "aha moments" should use class "aha"
7. Important:
- When applying class styles to nodes, do NOT use the ":::" syntax. Instead, define classes separately with classDef statements and then apply them using "class NodeName ClassName" syntax. For example, use "class A question" rather than "A:::question".
- Ensure all nodes are connected in a single unified flowchart. There should be no disconnected components or floating nodes. Every node must have at least one connection to another node in the diagram.
- Use special node styles (refinement and aha) sparingly and only when truly justified by the content. A node should only be classified as "refinement" if it explicitly revises a previous conclusion, and as "aha" only for genuine breakthrough moments that fundamentally change the direction of reasoning.
- Try to capture all significant steps from the original text. Do not oversimplify or omit important reasoning steps even if the input is lengthy.
- Do not use Python-style comments in the Mermaid code.
Please visualize the thinking steps from the original reasoning process as a proper Mermaid flowchart.`;
