SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Compress long prompts and contexts by reducing token usage while preserving semantic meaning, enabling faster processing and lower costs.

Core Features & Use Cases

  • Whitespace normalization and clutter removal to compact prompts.
  • Abbreviation and phrase simplification to preserve meaning with fewer tokens.
  • Optional preservation of code blocks to ensure programming contexts remain intact.
  • Use cases include long instructions, research prompts, and verbose system prompts that must fit token limits.

Quick Start

Provide a concise, actionable prompt that your AI should compress, with an optional target_ratio and preserve_code setting.

FAQPage Schema
How do I compress long prompts to reduce token usage without losing semantic meaning?

To compress long prompts without losing semantic meaning, the skill normalizes whitespace, abbreviates phrases, and removes low-information sentences. This reduces token usage in lengthy instructions or system prompts while preserving the core context.

Can I preserve code blocks when compressing a verbose prompt?

Yes, you can preserve code blocks when compressing verbose prompts by using the preserve_code option. This ensures programming contexts and code snippets remain completely intact during the whitespace normalization and abbreviation process.

What is the best way to shorten research prompts that approach token limits?

The best way to shorten research prompts approaching token limits is applying a target_ratio to guide compression. This removes clutter and abbreviates phrases, effectively compacting the context to fit within strict token constraints.

Does prompt compression remove whitespace and abbreviate phrases automatically?

Yes, prompt compression automatically normalizes whitespace and abbreviates phrases. It identifies and removes low-information sentences to compact lengthy instructions, ensuring the resulting text uses fewer tokens while retaining functional requirements.

What are the limitations of using target_ratio for prompt compression?

A limitation of using target_ratio for prompt compression is that aggressively reducing tokens may strip necessary context. If preserve_code is disabled, formatting within code blocks may also be altered or lost during the abbreviation process.
