AI agents call get_article to retrieve information from Egov Law without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns article text from a legal database without any side effects, data modification, or execution of external operations. It is a straightforward read operation on static legal content with attribution included. Low severity because misuse would only expose information that is already public (Japanese laws from e-Gov are public records).
From the tool's definition Tool description states 'Retrieve a specific article from e-Gov Law Search' — retrieval with no modification or deletion. Name 'get_article' and verb 'Retrieve' indicate read-only query operation.
