Text Truncator Tool
Functionality
Intelligently truncate text while maintaining content integrity and semantic coherence, limiting text to a specified length.
Usage Scenarios
- Preprocess text that exceeds length limits to meet agent input requirements
- Extract key sections for text previews or summary generation to improve efficiency and readability
- Assist content creation by intelligently trimming generated long text to avoid redundancy
Core Capabilities
- Semantic-Priority Truncation: Prioritize truncation at natural semantic boundaries (periods, question marks, exclamation points) to maximize sentence integrity
- Paragraph Integrity: When semantic boundaries are insufficient, prioritize truncation at paragraph ends or line breaks to avoid breaking paragraph structure
- Precise Length Control: Strictly adhere to user-specified maximum length limits, ensuring output text does not exceed limits
- Truncation Marker Insertion (optional): Automatically add custom truncation markers (such as "...") at the end of truncated text to indicate content omission
Input Requirements
- Text Content: Original text to be truncated (string)
- Maximum Length Limit: Maximum length after text truncation (integer, such as character count or token count)
- Truncation Marker (optional): Custom truncation marker, such as "..." or "[content truncated]"
Output Format
[Text Truncation Report]
- Original text length: [integer] words/tokens
- Truncated length: [integer] words/tokens
- Truncation position: [position description, such as "at end of sentence X"] or "not truncated"
### Truncated Text
[truncated text content]
Constraints
- Truncated text length must strictly comply with maximum length limits
- Ensure truncated text remains as semantically coherent and complete as possible
- If text does not reach maximum length, do not truncate; return original text
- Output format must be structured, clearly displaying length information before and after truncation and truncated text content
