Summarize lengthy plain text into a concise TL;DR and 3-5 key bullet points, preserving important names, dates, and figures verbatim.

Text Summarizer

Summarize long text into structured bullet points.

When to use

• User pastes a long article and asks for a summary
• User provides a document and wants key takeaways
• User asks "summarize this" with a text block

Prerequisites

• Access to an LLM tool (e.g., llm-task or any chat model)
• Input text is plain text (no binary files)

Steps

1. Receive input — Read the full text provided by the user. If the text is in a file, read it first.
2. Determine length — If text is under 200 words, skip summarization and acknowledge it's already short.
3. Generate summary — Use the LLM to produce a structured summary:
   • 3–5 key bullet points
   • One-sentence TL;DR at the top
   • Preserve important names, dates, and figures verbatim
4. Format output — Present as:

   text

   **TL;DR:** <one sentence>
   
   **Key Points:**
   - <bullet>
   - <bullet>
   

5. Deliver — Return the formatted summary to the user.

Example prompt for LLM

text

Summarize the following text into a TL;DR sentence plus 3-5 key bullet points. Preserve names, dates, and numbers exactly. Keep it concise.

TEXT:
{input_text}

Notes

• If the text is technical, include domain-specific terms in the summary.
• If the user asks for a specific format (e.g., paragraph instead of bullets), honor that.
• For text over 5000 words, consider summarizing section by section.
