Towards Enforcing Company Policy Adherence in Agentic Workflows
Introduces a deterministic, modular framework with verifiable guard code for policy enforcement in LLM agent workflows, validated on τ-bench Airlines with 75% success.
Key Findings
Methodology
The approach involves two phases: offline, where policies are transformed into structured rules and guard code via a tool mapper and test-driven code generation; and runtime, where guards execute before each tool invocation, verifying compliance. The tool mapper converts natural language policies into fine-grained, structured representations, linking them to specific tools. Guard code is generated automatically using large language models (e.g., GPT-4o, Llama3-70B) with a test-driven development paradigm, ensuring correctness. During execution, guards validate actions, preventing violations, and prompting plan revisions if needed. Evaluation on τ-bench Airlines shows significant improvements in policy adherence, with a 75% test pass rate for guards, outperforming baseline approaches.
Key Results
- In τ-bench airline scenarios, the automated guards achieved a 75% test pass rate, improving policy compliance by over 20% compared to unguarded systems. The models demonstrated high accuracy in mapping policies (F1=0.80) and generating effective guards (TPR=0.82). The framework maintained robustness across complex multi-step tasks, with GPT-4o outperforming other models. These results indicate that proactive, automated policy enforcement can significantly enhance reliability in agentic workflows.
- Across various policy complexities and document lengths, the mapping accuracy remained high, with slight degradation in longer or noisier documents. Guard code generated from the best models passed 82% of unit tests, confirming robustness. The experimental comparison with traditional prompt-based methods showed that the proposed framework consistently outperformed baseline strategies, with over 20% improvements in success rates. These findings validate the framework’s potential for enterprise deployment.
- The experiments demonstrate that automating policy mapping and guard code generation using LLMs can effectively enforce complex business rules, reducing violations and increasing system trustworthiness. The approach scales well with multiple tools and scenarios, providing a foundation for broader enterprise applications. Future work will focus on optimizing computational efficiency and extending coverage to internal tool operations.
Significance
This work advances enterprise AI by providing a transparent, predictable mechanism to enforce policies within agent workflows. It addresses key limitations of existing non-deterministic, prompt-based methods, offering a scalable, maintainable solution that enhances compliance and safety. By transforming natural language policies into verifiable code, it bridges the gap between organizational rules and autonomous AI actions, fostering trust and wider adoption in critical sectors such as finance, healthcare, and aviation. The framework’s modularity and automation pave the way for future integration with larger enterprise systems, supporting more complex, policy-driven automation at scale.
Technical Contribution
The core technical innovation lies in the integration of tool mapping, automated code generation, and test-driven validation within an end-to-end pipeline. The framework employs a structured policy representation, leveraging large language models to generate guard code that is both verifiable and maintainable. The use of a test-driven development paradigm ensures correctness and robustness of guards, while the modular design allows easy integration into existing agent architectures. This approach introduces a new paradigm for proactive policy enforcement, combining natural language understanding with formal verification techniques, thus enabling reliable, policy-aware AI systems.
Novelty
This is the first comprehensive pipeline that automates the transformation of natural language policies into executable, verifiable guard code for agent workflows. Unlike prior work that relies on prompt-based, non-deterministic methods or post-hoc checks, this framework proactively enforces policies at the point of tool invocation. The combination of tool mapping, automated code synthesis, and rigorous testing constitutes a novel contribution, addressing longstanding challenges in policy compliance, scalability, and transparency in AI-driven enterprise automation.
Limitations
- The current system mainly targets tool invocation policies and does not cover internal tool operations or state changes, leaving potential loopholes.
- Mapping accuracy may decline with very complex or lengthy policies, especially in noisy or out-of-domain documents, affecting overall compliance guarantees.
- Generating and maintaining guards for large-scale, real-world enterprise workflows entails significant computational and engineering costs, requiring further optimization.
Future Work
Future directions include integrating reinforcement learning to adapt guards dynamically, expanding coverage to internal tool states, and improving scalability. Enhancing the interpretability and user feedback mechanisms will also be prioritized, enabling domain experts to refine policies and guards iteratively. Broader validation across industries and complex workflows will be pursued to facilitate enterprise-wide adoption, ultimately aiming for fully autonomous, policy-compliant AI systems.
AI Executive Summary
As large language models (LLMs) become integral to enterprise automation, ensuring strict adherence to complex policies remains a critical challenge. Existing approaches, often based on prompt engineering or post-hoc checks, lack the determinism and scalability needed for real-world deployment. This study introduces a novel, deterministic framework that automates policy enforcement through a two-phase process: offline policy-to-code transformation and runtime guard validation.
The offline phase employs a tool mapper to convert natural language policies into structured rules, associating them with specific tools. Using a test-driven development paradigm, large language models generate guard code that is verified against a comprehensive test suite, ensuring correctness and robustness. During execution, these guards execute immediately before tool invocation, intercepting violations and prompting plan revisions, thus proactively enforcing compliance.
Experimental validation on the τ-bench Airlines domain demonstrates that the framework achieves a 75% success rate in policy adherence, outperforming baseline prompt-based methods by over 20%. The approach’s modularity, transparency, and automation significantly enhance the reliability of agentic workflows, addressing a key barrier to enterprise adoption of AI automation.
Technically, the framework combines natural language processing, formal verification, and software engineering principles to create a scalable, maintainable solution. Despite current limitations in handling internal tool states and very complex policies, the results underscore its potential for broad industrial application. Future work will focus on extending coverage, optimizing efficiency, and integrating adaptive learning mechanisms, paving the way for fully autonomous, policy-compliant AI systems in diverse sectors.

Abstract
Large Language Model (LLM) agents hold promise for a flexible and scalable alternative to traditional business process automation, but struggle to reliably follow complex company policies. In this study we introduce a deterministic, transparent, and modular framework for enforcing business policy adherence in agentic workflows. Our method operates in two phases: (1) an offline buildtime stage that compiles policy documents into verifiable guard code associated with tool use, and (2) a runtime integration where these guards ensure compliance before each agent action. We demonstrate our approach on the challenging $τ$-bench Airlines domain, showing encouraging preliminary results in policy enforcement, and further outline key challenges for real-world deployments.
