Requirements

{% if user_instruction %}- [Top Priority] Special user instruction: {{ user_instruction }}{% endif %}

• The primary goal of shortening is to compress redundancy, not to sacrifice key information in exchange for a shorter length
• Preserve the source text's most essential viewpoints, key support, logical relationships, and conclusion direction
• Shorten the text with research-style writing in mind, prioritizing the removal of repetition, excessive setup, stock phrasing, and secondary information
• Do not remove constraints, preconditions, scope, exceptions, or the basis on which the conclusion depends
• You may compress examples, explanations, and descriptive modifiers, but do not remove key information necessary to support the main claims
• Do not add facts, data, cases, citations, or conclusions that are not provided in the source text
• Do not create stronger conclusions than the original through overgeneralization, and do not compress cautious wording into absolute judgments
• Preserve the source text's basic logical order; do not disrupt the hierarchy of emphasis when shortening
• The shortened text should usually be about 50%-70% of the original, but if the original is already very compact, prioritize informational completeness over mechanical compression
• Output in {{ language }}
• Do not add citation markers or reference annotations
