Gpt 5.3 Codex's response to the 'Adversarial Contract Review' challenge.
Here is a contract for a software consulting engagement: --- SOFTWARE CONSULTING AGREEMENT This Agreement is entered into between TechCorp Solutions Inc. ("Client") and [Contractor Name] ("Contractor"). 1. SCOPE: Contractor shall provide software development services as directed by Client. Client reserves the right to modify the scope at any time without additional compensation. 2. PAYMENT: Contractor shall be paid $150/hour, invoiced monthly. Payment is due within 90 days of invoice receipt. Client may withhold payment if deliverables are deemed "unsatisfactory" at Client's sole discretion. 3. INTELLECTUAL PROPERTY: All work product, including any tools, libraries, or methodologies developed during the engagement, shall be the exclusive property of Client in perpetuity, including any work created using Contractor's pre-existing IP. 4. NON-COMPETE: Contractor agrees not to provide similar services to any company in the same industry as Client for 24 months following termination. 5. TERMINATION: Client may terminate this agreement at any time without notice. Contractor must provide 60 days written notice. Upon termination, Contractor must immediately deliver all work in progress without additional compensation. 6. LIABILITY: Contractor assumes all liability for any bugs, security vulnerabilities, or system failures in delivered software, including consequential damages, with no cap on liability. 7. INDEMNIFICATION: Contractor shall indemnify Client against all claims arising from Contractor's work, including claims by third parties, regardless of fault. 8. CONFIDENTIALITY: Contractor shall not disclose any information about this engagement, including the terms of this agreement, for 5 years after termination. 9. DISPUTE RESOLUTION: Any disputes shall be resolved through binding arbitration in Client's home jurisdiction, with costs borne by the losing party. --- Find all clauses that could be exploited against the contractor, suggest specific modifications, and explain the legal reasoning.
Great prompt. This draft is very one-sided and has multiple provisions that could be used against the contractor.
Quick note: I’m not a lawyer, and enforceability depends on jurisdiction. This is practical contract-risk spotting, not legal advice.
Current risk:
“Client reserves the right to modify the scope at any time without additional compensation.”
How it can be exploited:
Suggested modification:
Sample language:
“Any material change to scope, deliverables, assumptions, or timeline must be documented in a written change order signed by both parties. Contractor will be compensated at the agreed rate for additional work.”
Legal reasoning:
Avoids illusory obligations and ambiguity; creates objective, enforceable process for expanded work.
Current risk:
How exploited:
Suggested modification:
Sample language:
“Invoices are due within 15 days. Client must notify Contractor in writing of any disputed amounts within 10 business days, with reasonable detail. Client shall timely pay all undisputed amounts. Late payments accrue interest at 1.0–1.5% per month (or maximum lawful rate). Contractor may suspend services for nonpayment after 10 days’ notice.”
Legal reasoning:
Creates objective payment obligations and limits bad-faith withholding.
Current risk:
“All work product… including work created using Contractor’s pre-existing IP” belongs exclusively to Client.
How exploited:
Suggested modification:
Sample language:
“Contractor retains all right, title, and interest in pre-existing and independently developed tools, libraries, methodologies, and know-how (‘Background IP’). Upon full payment, Contractor assigns to Client all right, title, and interest in the specific deliverables created under this Agreement, excluding Background IP. Contractor grants Client a perpetual, worldwide, non-exclusive, royalty-free license to use any embedded Background IP solely as incorporated in the deliverables.”
Legal reasoning:
Standard IP carve-out protects contractor’s core assets while giving Client practical usage rights.
Current risk:
No “similar services” to any company in same industry for 24 months.
How exploited:
Suggested modification:
Sample language:
“Contractor will not use Client Confidential Information to compete unfairly and will not solicit Client employees or customers introduced through this engagement for 12 months. No broad industry-wide non-compete applies.”
Legal reasoning:
Courts scrutinize restraints on trade; narrow restrictions tied to legitimate business interests are more defensible.
Current risk:
How exploited:
Suggested modification:
Sample language:
“Either party may terminate for convenience with 15 days’ written notice. Either party may terminate for material breach if uncured after 10 days’ notice. Client shall pay Contractor for all services performed and approved expenses incurred through termination date. Any transition assistance will be billed at the then-current rate.”
Legal reasoning:
Prevents unjust enrichment and improves reciprocity/fair dealing.
Current risk:
Contractor bears unlimited liability for bugs/security/system failures, including consequential damages.
How exploited:
Suggested modification:
Sample language:
“Except for willful misconduct, fraud, or each party’s indemnification obligations, neither party is liable for indirect, incidental, special, consequential, or punitive damages. Contractor’s aggregate liability shall not exceed the total fees paid or payable under this Agreement in the 12 months preceding the claim.”
Legal reasoning:
Risk allocation must be commercially reasonable and insurable.
Current risk:
Contractor indemnifies Client against all claims “regardless of fault.”
How exploited:
Suggested modification:
Sample language:
“Contractor will indemnify Client from third-party claims to the extent caused by Contractor’s gross negligence, willful misconduct, or infringement by deliverables as provided. Client will indemnify Contractor for claims arising from Client-provided materials, specifications, unlawful instructions, or Client’s modifications/use outside intended scope.”
Legal reasoning:
Indemnity should track fault and control; “regardless of fault” is unusually harsh and potentially unconscionable.
Current risk:
Cannot disclose anything about engagement, including contract terms, for 5 years.
How exploited:
Suggested modification:
Sample language:
“Confidentiality obligations shall not apply to information that is public through no fault of recipient, already known, independently developed, or rightfully received from a third party. Contractor may disclose Confidential Information as required by law, and to legal/financial advisors under confidentiality duties. This clause survives 3–5 years; trade secrets remain protected as long as legally protected.”
Legal reasoning:
Maintains protection while preserving lawful/operational disclosures.
Current risk:
Arbitration in Client’s home jurisdiction; loser pays all costs.
How exploited:
Suggested modification:
Sample language:
“Disputes will be resolved by binding arbitration under [AAA/JAMS] rules in a mutually agreed neutral venue (or remotely). Each party bears its own attorney fees unless arbitrator awards fees for bad-faith conduct or as required by law. Parties will attempt good-faith negotiation for 30 days before filing.”
Legal reasoning:
Reduces procedural unfairness and access-to-justice barriers.
If you want, I can produce a clean revised contractor-friendly version of this entire agreement, or a balanced redline that is more likely to be accepted by a corporate client.
