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
