What it does
Contract Analyzer is an agent skill from revfactory/harness-100. A pipeline where an agent team performs contract analysis, drafting, review, and risk assessment. Use this skill for contexts such as 'review the contract', 'contract analysis', 'draft a contract', 'contract risk assessment', 'contract review', 'clause modification', 'contract comparison', 'NDA review', 'service agreement', 'lease agreement', 'employment contract', 'license agreement', and other contract management tasks. Note: Providing legal counsel, conducting litigation, notarization, and court document…
Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Legal & Compliance, covering Contract review. The licence is Apache-2.0.
When your agent uses it
- Contexts such as review the contract
- Contract analysis
- Draft a contract
- Contract risk assessment
Example prompts
- “review the contract”
- “contract analysis”
- “draft a contract”
- “/contract-analyzer”
Workflow steps
3 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 8e8d35c. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Contract Analyzer loads about 1.8k tokens when it runs. Until then it costs about 145 tokens; SKILL.md has 694 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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.
Agent Composition
| Agent | File | Role | Type |
|---|---|---|---|
| clause-analyst | .claude/agents/clause-analyst.md | Clause structure, interpretation, essential clause verification | general-purpose |
| clause-drafter | .claude/agents/clause-drafter.md | Clause drafting, amendment proposals | general-purpose |
| risk-assessor | .claude/agents/risk-assessor.md | Legal and business risk assessment | general-purpose |
| comparison-reviewer | .claude/agents/comparison-reviewer.md | Standard/previous version comparison, negotiation points | general-purpose |
| contract-coordinator | .claude/agents/contract-coordinator.md | Comprehensive opinion, consistency verification | general-purpose |
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
Phase 2: Team Assembly and Execution
| Order | Task | Owner | Dependencies | Output |
|---|---|---|---|---|
| 1 | Clause Analysis | clause-analyst | None | _workspace/01_clause_analysis.md |
| 2a | Risk Assessment | risk-assessor | Task 1 | _workspace/03_risk_assessment.md |
| 2b | Comparison Review | comparison-reviewer | Task 1 | _workspace/04_comparison_report.md |
| 3 | Clause Drafting/Revision | clause-drafter | Tasks 1, 2a, 2b | _workspace/02_draft_clauses.md |
| 4 | 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
- Clause Analysis Report —
Modes by Request Scope
| User Request Pattern | Execution Mode | Agents Deployed |
|---|---|---|
| "Review this contract", "Full analysis" | Full Analysis | All 5 agents |
| "Draft a contract", "Write a contract" | Drafting Mode | clause-drafter + risk-assessor + contract-coordinator |
| "Just assess the risk" | Risk Mode | clause-analyst + risk-assessor |
| "Compare with previous version" | Comparison Mode | clause-analyst + comparison-reviewer |
| "Modify this clause" | Amendment Mode | clause-drafter only |
Using Existing Files: If comparison targets (standard, previous version) are provided, comparison-reviewer utilizes them.

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
Agent Extension Skills
| Agent | Extension Skill | Purpose |
|---|---|---|
| risk-assessor, clause-analyst | clause-risk-database | Risk clause pattern DB, risk scoring algorithm |
| clause-drafter, comparison-reviewer | negotiation-playbook | Negotiation strategy framework, amendment wording templates |
