List all available articles.
AI agents call listar_artigos to retrieve information from Philosophy 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 a list of articles from the philosophy corpus without modifying, deleting, or executing any operations. It is a straightforward read operation that retrieves metadata about available content. The blast radius of misuse is minimal—an agent could only enumerate articles, not alter or access restricted data.
From the tool's definition Tool name 'listar_artigos' (list articles) and description 'List all available articles' indicate a retrieval operation with no side effects.
