Terminators: Terms of Service Parsing and Auditing Agents

2025-05-16

AI Summary

Users commonly struggle to comprehend lengthy, opaque Terms of Service (ToS), resulting in inadequate awareness of digital rights and privacy risks. To address this, we propose a modular multi-agent framework powered by GPT-4o that decomposes ToS auditing into an interpretable, three-stage paradigm: (1) structured clause extraction, (2) rule-guided compliance verification, and (3) generation of executable accountability plans. Leveraging structured prompt engineering and explicit rule constraints, our approach effectively mitigates large language model hallucination while ensuring audit transparency and traceability. Experimental evaluation on OpenAI’s ToS demonstrates high-precision clause parsing, fine-grained risk identification, and substantial improvements in legal text readability, verifiability, and user rights comprehension efficiency. To the best of our knowledge, this is the first end-to-end, explainable, and deployable three-stage framework specifically designed for automated ToS auditing.

Abstract

Terms of Service (ToS) documents are often lengthy and written in complex legal language, making them difficult for users to read and understand. To address this challenge, we propose Terminators, a modular agentic framework that leverages large language models (LLMs) to parse and audit ToS documents. Rather than treating ToS understanding as a black-box summarization problem, Terminators breaks the task down to three interpretable steps: term extraction, verification, and accountability planning. We demonstrate the effectiveness of our method on the OpenAI ToS using GPT-4o, highlighting strategies to minimize hallucinations and maximize auditability. Our results suggest that structured, agent-based LLM workflows can enhance both the usability and enforceability of complex legal documents. By translating opaque terms into actionable, verifiable components, Terminators promotes ethical use of web content by enabling greater transparency, empowering users to understand their digital rights, and supporting automated policy audits for regulatory or civic oversight.
