The Agent Skills Directory

Indirect Prompt Injection Surface: The skill demonstrates how to create agents that ingest and process external user input via message payloads. This architecture introduces a potential surface for indirect prompt injection where untrusted data might influence agent behavior. However, the documentation provides remediation strategies, such as implementing human-in-the-loop approval via middleware and setting recursion limits to prevent infinite loops.
Library Dependencies: The code examples reference standard packages from the LangChain ecosystem and common data validation libraries. These dependencies are consistent with the skill's stated purpose of providing foundational development patterns and trace back to expected vendor infrastructure.
