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 orReview_Result_{ContractName}for English - •Reviewed contract:
{ContractName}_审核版.docxfor Chinese or{ContractName}_Reviewed.docxfor English - •Review report:
审核报告.txtfor Chinese orReview_Report.txtfor 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.
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.
Outputs:

li## Technical Notes
Core workflow:
- •Unpack → 2. Add comments → 3. Summary → 4. Opinion → 5. Flowchart → 6. Repack
API & implementation details:
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
mmdcinstalled; 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
