DESCRIPTION

Compresses a long prompt down to a target ratio of its original length while preserving every instruction, constraint, and example's intent. Drops filler words, redundant repetition, and ceremonial politeness. Powered by Venice mistral-small-3-2-24b. Use it as a prompt compressor, context shrinker, prompt distiller, or cost-cutter for long system prompts.
