text-truncator

# 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 ## Examples See `{baseDir}/references/examples.md` for more detailed examples: - `examples.md` - Contains truncation examples for different lengths, different truncation markers, and complex text structures ## Detailed Documentation See `{baseDir}/references/examples.md` for detailed guidance and cases on the text truncator tool. --- ## Version History | Version | Date | Changes | |---------|------|---------| | 2.1.0 | 2026-01-11 | Optimized description field; changed model to opus; optimized descriptions for functionality, core capabilities, input requirements, and output format; added usage scenarios, constraints, examples, and detailed documentation sections | | 2.0.0 | 2026-01-11 | Restructured according to official specifications | | 1.0.0 | 2026-01-10 | Initial version |
