Contract Review

Contract Review Skill

Overview

This skill performs contract reviews by adding comments only (no edits to the original text). It follows a three-layer review (basic, business, legal) and generates:

• Annotated contract (.docx)
• Contract summary (.docx)
• Consolidated review opinion (.docx)
• Business flowchart (Mermaid + rendered image)

Language rule: detect the contract’s dominant language and output all generated content (comments, summary, opinion, flowchart text) in that language. Use the guidance in references/language.md.

Workflow

• Unpack the contract (.docx) for XML operations
• Read contract text (pandoc or XML)
• Execute three-layer review
• Add comments to the document
• Generate contract summary
• Generate consolidated opinion
• Generate business flowchart and render image
• Repack to .docx

Output Naming

• Output directory: 审核结果：{ContractName} for Chinese or Review_Result_{ContractName} for English
• Reviewed contract: {ContractName}_审核版.docx for Chinese or {ContractName}_Reviewed.docx for English
• Review report: 审核报告.txt for Chinese or Review_Report.txt for English

Comment Principles

• Comments only: do not modify the original text or formatting
• Precise anchoring: comment should target specific clauses/paragraphs
• Structured content: each comment includes issue type, risk reason, and revision suggestion
• Risk level: carried by reviewer name; do not include a “risk level” line in comment body
• Output language: use labels in the contract’s language (see references/language.md)

Comment example (English):

[Issue Type] Payment Terms
[Risk Reason] The total amount is stated as USD 100,000 in Section 3.2, but the payment clause lists USD 1,000,000 in Section 5.1. This inconsistency may cause disputes.
[Revision Suggestion] Align the total amount across clauses and clarify whether tax is included.

Review Standards

Use the three-layer review model and the detailed checklist in references/checklist.md.

Layer 1: Basic (text quality)

• Accuracy of numbers, dates, terms
• Consistent numbering and references
• Clarity and lack of ambiguity
• Formatting and punctuation quality

Layer 2: Business terms

• Scope, deliverables, quantity/specs
• Pricing and payment schedule
• Delivery/acceptance procedures
• Rights/obligations and performance guarantees

Layer 3: Legal terms

• Effectiveness and term/termination
• Liability/penalties and remedies
• Dispute resolution and governing law
• Confidentiality, force majeure, IP, notice, authorization

Risk levels (encoded in reviewer name):

• 🔴 High: core business ambiguity (price, scope, rights/obligations)
• 🟡 Medium: material but non-core ambiguity
• 🔵 Low: minimal practical impact

Contract Summary

Generate a structured, objective summary in the contract’s language.

• See references/summary.md (English template)
• Use references/language.md for language selection and Chinese labels

Output file: 合同概要.docx for Chinese or Contract_Summary.docx for English (default font: 仿宋; adjust if language requires)

Consolidated Opinion

Generate a concise, two-paragraph response for the business team in the contract’s language.

• See references/opinion.md

Output file: 综合审核意见.docx for Chinese or Consolidated_Opinion.docx for English (default font: 仿宋; adjust if language requires)

Business Flowchart (Mermaid)

Generate Mermaid flowchart per requirements and render to image.

• See references/flowchart.md

Outputs:

• business_flowchart.mmd
• business_flowchart.png

li## Technical Notes

Core workflow:

• Unpack → 2. Add comments → 3. Summary → 4. Opinion → 5. Flowchart → 6. Repack

API & implementation details:

• references/technical.md

Dependencies

• Python 3.9+ (3.10+ recommended)
• pandoc (system install)
• defusedxml
• Mermaid CLI (mmdc) for rendering
• python-docx for rich text output

Troubleshooting (Short)

• Comments missing in Word: run doc.verify_comments() and re-save
• find_paragraph fails: shorten search text; confirm actual paragraph text
• Mermaid render fails: ensure mmdc installed; use Chrome path or Puppeteer config

Examples

See references/examples.md for a full workflow example.

Important Rules

• Never alter original contract text
• Review all three layers, do not skip items
• Ensure risk level is accurate and consistent
• Keep comments precise, professional, and actionable
• Flowchart must come strictly from the contract text
• Summary is objective only; no risk analysis
• Opinion only reflects findings already identified
