Learn to mitigate prompt injection in LLM agents by separating instruction and data channels at the system level
Action Steps
- Identify potential vulnerabilities in your LLM system to prompt injection
- Design a middleware layer to separate instruction and data channels
- Implement input filtering and model-side alignment as additional mitigation strategies
- Test your system with various prompts and data sources to evaluate its robustness
- Apply the system-level approach to your agentic workflows to prevent prompt injection failures

Prompt injection has emerged as one of the most persistent failure modes in tool-using LLM systems, particularly in agentic workflows where models interact with external data sources. Most mitigation strategies focus on input filtering or model-side alignment, but these approaches struggle because the core issue is structural: Approach I explored a system-level mitigation strategy by introducing a middleware laye
