when_to_use
Use this skill only after two or more document contents are already available from pasted text, chat context, or the system document parser. Do not use it to directly read, parse, extract, OCR, or inspect uploaded PDF, Word, TXT, Markdown, scanned files, or other file bytes. If the user asks to export the comparison as Word, PDF, Markdown, or another file, produce the comparison content first and then route it to file-generator.

Multi-document Compare Skill
Use this skill to compare two or more available document contents. This skill performs comparison and synthesis only; it does not read files, parse file formats, OCR images, generate redlines, or create downloadable files.
Scope
Use this skill for:
Contract version comparison and clause difference review.
Proposal version comparison and solution change tracking.
Multi-vendor proposal comparison across dimensions such as price, delivery, responsibilities, timeline, risks, and functions.
Identifying common points, differences, additions, deletions, modifications, conflicts, risks, and key version changes.
Do not use this skill to:
Directly read, parse, extract, or inspect uploaded files or file bytes.
Replace the system document parser.
Produce legal, compliance, procurement, or professional review as a final authority.
Make strong conclusions from unreadable, low-quality, incomplete, scanned, garbled, or partially parsed source content.
Generate Word, PDF, Markdown, TXT, CSV, XLSX, or any downloadable file directly.
Invent document content, clauses, prices, dates, responsibilities, risks, or conflicts not grounded in source text.
Routing Rules
If two or more document contents are already available from pasted text, chat context, or the system document parser, use this skill directly.
If the user uploads files and asks to compare them, use this skill only after the system document parser has provided structured content for at least two documents.
If the user only asks to read, extract, parse, inspect, or preserve original document text, do not use this skill; that is a document parsing task.
If the user says "read and compare", the system document parser must provide the source content first, then this skill compares the parsed content.
If the user asks to export the comparison result, produce the comparison content first, then route that content to file-generator.
Workflow
Confirm that at least two source documents are available as text, structured parsed content, or prior chat context.
Identify each document's name, version, date, source label, or role when available. If labels are missing, use neutral labels such as 文档A, 文档B, and 文档C in Chinese output.
Identify the comparison focus: generic comparison, version changes, clause conflicts, vendor comparison, requirements changes, or policy changes.
If the comparison focus is clear, read exactly one relevant reference before producing the comparison.
Extract shared points, differences, additions, deletions, modifications, conflicts, and risks only from source-backed content.
Preserve original numbers, dates, amounts, delivery times, responsibilities, clause names, requirement IDs, and scope constraints.
Clearly separate document-stated facts from inferred risks or recommendations.
If source quality is insufficient, state what cannot be judged and why.
If the user requests export after the comparison is prepared, hand the prepared content to file-generator.
Clarification Workflow
Call request_user_input instead of writing a plain clarification when a missing decision blocks a reliable comparison. Ask 1-4 focused questions. Options must be concrete answers that can be used directly. A single question may contain at most 5 options.
Ask when:
Fewer than two document contents are available.
Multiple parsed documents exist but the user did not specify which ones to compare.
The user says only "compare these documents" and the comparison focus is ambiguous.
The user did not specify whether they want summary, table, or detailed differences and the output depth matters.
The parsed source content is incomplete, garbled, scanned poorly, or missing critical sections.
The requested dimensions are unclear or too broad to compare reliably.
After calling request_user_input, stop the turn and wait for the user's answer.
Language Rules
Match the user's requested output language. If the user writes in Chinese or asks in Chinese, output all visible headings, field names, labels, and content in Chinese.
If the user explicitly asks for English, output all visible headings, field names, labels, and content in English.
Do not mix Chinese and English section headings in the final answer. Avoid English labels such as Summary, Diff, Comparison Table, Keywords, Risks, Owner, Due, and Notes in Chinese output.
For Chinese output, use Chinese labels such as 对比摘要, 共同点, 差异清单, 新增、删除、修改, 冲突点, 风险提示, 原文依据, and 待确认问题.
Keep product names, company names, protocol names, code identifiers, file formats, API names, and quoted source terms in their original language when translation would change meaning.
References
Read exactly one reference after choosing the comparison focus:
Requested comparison
Read reference
Generic comparison, common points, differences, conflicts, risks
generic-comparison.md
Version comparison, new/old version, additions, deletions, modifications
If the user asks for multiple comparison types, read the reference that matches the primary deliverable and include secondary sections only when they are directly supported by source content.
Constraints
Do not expose internal reasoning or mention this skill.
Do not output JSON unless the user explicitly asks for JSON.
Do not directly read, parse, extract, OCR, or inspect uploaded files.
Do not claim that files were parsed unless the system document parser already supplied parsed content.
Do not replace legal review, compliance review, procurement review, or other professional review.
Do not make strong conclusions when source content is missing, unreadable, incomplete, scanned poorly, garbled, or only partially parsed.
Every comparison conclusion must be grounded in document source text, parsed source content, or explicit user-provided content.
Do not fabricate additions, deletions, modifications, conflicts, risks, prices, dates, deadlines, responsibilities, or clauses.
Do not generate files directly. Use file-generator only after the comparison content is prepared and the user requested export.
