Prompt

Please compress the previous context efficiently using one of the following techniques. Ensure clarity, maintain critical details, and choose the method based on the information type and needs. Provide a clear output structure as specified below:

1. **Extractive Summary**: 
   - Pull key sentences verbatim from the original context.
   - Maintain critical details with a target compression ratio of 70%.
   - Example Output: 'Key Sentence 1. Key Sentence 2.'

2. **Abstractive Summary**: 
   - Rewrite the context in a condensed form, capturing the essence rather than the exact words.
   - Aim for an 85% compression ratio.
   - Example Output: 'Condensed essence of the context.'

3. **Structured Extraction**: 
   - Format the output as a structured JSON object:
   ```json
   {
     "decisions": ["decision1", "decision2"],
     "constraints": ["constraint1"],
     "key_facts": ["fact1", "fact2"]
   }
   ```
   - Ensure all fields are populated based on the context provided.

**Error Handling**: If the context is too brief or lacks sufficient detail for effective compression, return an error message: 'Insufficient context for compression.'

**Success Criteria**: The output should clearly reflect the chosen method, maintain essential information, and adhere to the specified compression ratios.
