Abstract: This paper presents an intelligent multi-agent system to improve clarity, accessibility, and legal compliance of public service descriptions on the Brazilian Gov.br platform. Leveraging large language models (LLMs) like GPT-4, agents with specialized contextual profiles simulate collective deliberation to evaluate, rewrite, and select optimal service texts based on ten linguistic and seven legal criteria. An interactive voting protocol enables consensus-based editorial refinement. Experimental results show the system produces high-quality texts that balance technical accuracy with linguistic simplicity. Implemented as a Mixture of Experts (MoE) architecture through prompt-conditioning and rhetorical configurations within a shared LLM, the approach ensures scalable legal and linguistic compliance. This is among the first MoE applications for institutional text standardization on Gov.br, establishing a state-of-the-art precedent for AI-driven public sector communication.
