Text Truncation Tool

Features

Usage Scenarios

• Preprocess text that exceeds length limits to meet the input requirements of agents.
• Extract key sections when displaying text previews or generating summaries to improve efficiency and readability.
• Assist content creation by intelligently cropping generated long texts to avoid redundancy.

Core Capabilities

• Semantics-Prioritized Truncation: Prioritize truncation at natural semantic boundaries (such as periods, question marks, exclamation marks) to maximize sentence integrity.
• Paragraph Integrity: When semantic boundaries are insufficient, prioritize truncation at the end of paragraphs or line breaks to avoid disrupting paragraph structure.
• Precise Length Control: Strictly adhere to the user-specified maximum length limit to ensure the output text does not exceed the limit.
• Optional Truncation Marker Insertion: Automatically add a custom truncation marker (such as "...") at the end of the truncated text to indicate omitted content.

Input Requirements

• Text Content: The original text to be truncated (string).
• Maximum Length Limit: The maximum length of the truncated text (integer, such as number of characters or tokens).
• Optional Truncation Marker: Custom truncation marker, such as "..." or "[Content Truncated]".

Output Format

【Text Truncation Report】

- Original Text Length: [Integer] characters/tokens
- Truncated Text Length: [Integer] characters/tokens
- Truncation Position: [Position description, e.g., "At the end of sentence X"] or "Not truncated"

### Truncated Text
[Truncated text content]

Constraints

• The length of the truncated text must strictly comply with the maximum length limit.
• Ensure the truncated text is as semantically coherent and complete as possible.
• If the text does not reach the maximum length, no truncation is performed and the original text is returned.
• The output format must be structured, clearly displaying length information before and after truncation and the truncated text content.
