The Agent Skills Directory

[SAFE]: No security issues detected. The skill instructions follow established patterns for AI development and state management.
[DYNAMIC_EXECUTION]: The implementation of the 'calculate' tool demonstrates security awareness by explicitly avoiding eval() for processing model-generated strings. Instead, it uses Python's ast module to safely traverse and evaluate mathematical expressions, which prevents arbitrary code execution.
[EXTERNAL_DOWNLOADS]: The skill references and installs standard, well-known packages from the LangChain ecosystem (langgraph, langchain, langchain-openai) which are maintained by a trusted organization.
[CREDENTIALS_UNSAFE]: The skill correctly instructs users to manage sensitive credentials like OPENAI_API_KEY through environment variables rather than hardcoding them into the scripts.
