Idea
A secure Plan-then-Execute framework for building reliable LLM agents that improve reasoning and resist prompt injection attacks for AI developers.
Research Paper
Core Innovation
This paper presents the Plan-then-Execute pattern that distinctly separates strategic planning from tactical execution in LLM agents, improving security and operational efficiency. It uniquely addresses indirect prompt injection attacks by enforcing control-flow integrity and advocates a defense-in-depth approach. The paper also provides practical implementation blueprints for popular LLM frameworks and explores advanced execution patterns to enhance agent robustness.

Research Paper Overview
Architecting Resilient LLM Agents: A Guide to Secure Plan-then-Execute Implementations
Summary
This paper introduces the Plan-then-Execute pattern for Large Language Model agents, separating strategic planning from tactical execution to enhance predictability, cost-efficiency, and reasoning quality. It highlights security advantages, especially resilience to indirect prompt injection attacks via control-flow integrity, and promotes defense-in-depth principles like least privilege and sandboxed execution. Implementation blueprints for LangChain, CrewAI, and AutoGen frameworks are provided, along with advanced patterns such as dynamic re-planning, parallel execution, and human-in-the-loop verification to build robust, trustworthy LLM agents.
