Contract Analyzer — Contract Analysis, Drafting, and Review Pipeline
An agent team collaborates to perform clause analysis, drafting/revision, risk assessment, comparison review, and comprehensive opinion.
Warning: This pipeline does not replace professional legal advice.
Execution Mode
Agent Team — 5 agents communicate directly via SendMessage and cross-verify each other's work.

Workflow
Phase 1: Preparation (Performed Directly by Orchestrator)
- Extract from user input:
- Contract Text: The contract to analyze (file or text)
- Contract Type: Sale/Service/Lease/NDA/Employment/License, etc.
- Party Position: User's position as Party A or Party B
- Special Concerns (optional): Specific clauses, risks, comparison targets
- Comparison Target (optional): Standard template, previous version
- Create the
_workspace/ directory in the project root
- Organize the input and save to
_workspace/00_input.md
- If contract text is available, copy to
_workspace/original_contract.md
- Determine the execution mode based on the requested scope

Comprehensive Opinion |
contract-coordinator |
Tasks 1, 2a, 2b, 3 |
_workspace/05_final_opinion.md |
Tasks 2a (Risk) and 2b (Comparison) are executed in parallel.
Inter-agent Communication Flow:
- clause-analyst completes -> Delivers risk clauses to risk-assessor, structural info to comparison-reviewer
- risk-assessor + comparison-reviewer complete -> Deliver modification requirements to clause-drafter
- clause-drafter completes -> contract-coordinator comprehensively verifies all deliverables
- contract-coordinator: If Red inconsistencies found, requests revision from relevant agent -> rework -> re-verify (up to 2 times)
Phase 3: Integration and Final Deliverables
- Review all files in
_workspace/
- Verify that all Red required actions in the comprehensive opinion are reflected in the amendments
- Report the final summary to the user:
- Clause Analysis Report —
01_clause_analysis.md
- Amendments —
02_draft_clauses.md
- Risk Assessment —
03_risk_assessment.md
- Comparison Review —
04_comparison_report.md
- Comprehensive Opinion —
05_final_opinion.md

Data Transfer Protocol
| Strategy |
Method |
Purpose |
| File-based |
_workspace/ directory |
Storing and sharing main deliverables |
| Message-based |
SendMessage |
Real-time delivery of key information, revision requests |
| Web Browsing |
WebSearch/WebFetch |
Standard templates, related laws, case law research |
Error Handling
| Error Type |
Strategy |
| No contract text |
Switch to drafting mode based on standard template for the contract type |
| Party position unclear |
Analyze from both Party A and Party B perspectives, request position confirmation from user |
| Governing law unclear |
Default analysis based on domestic law, note possibility of other applicable laws |
| Web search failure |
Work based on general legal knowledge, note "latest case law unverified" |
| Agent failure |
Retry once -> if failed, proceed without that deliverable, note omission in report |
Test Scenarios
Normal Flow
Prompt: "Review this software development service contract. We are Party B (the contractor)." + contract file provided
Expected Results:
- Clause Analysis: Full structure map, clause-by-clause legal and practical analysis, essential clause check
- Risk Assessment: Risks from Party B's perspective, disadvantageous clause identification, mitigation strategies
- Comparison Review: Differences from software development standard contract
- Amendments: Revised wording for disadvantageous clauses, additional protective clauses
- Comprehensive Opinion: Signing feasibility, required modification list, checklist
New Drafting Flow
Prompt: "Draft a freelance design service contract. I am Party A."
Expected Results:
- Drafting Mode: clause-drafter creates standard service contract draft
- risk-assessor checks risks of the drafted document
- contract-coordinator performs final verification
Error Flow
Prompt: "Check if this contract is okay" + English NDA provided
Expected Results:
- English NDA analysis, key terms annotated in both languages
- Analysis based on domestic law, with explanation of common law practice differences
- Governing law verification recommendation included in comprehensive opinion
