AI agents call list_iniciativas to retrieve information from Openar without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries legislative initiatives from the Portuguese Parliament open data API with optional filtering parameters. The verb 'list' and the read-only nature of querying public parliamentary data (no mutations, no side effects) clearly place it in the Read category. Severity is low because accessing public parliamentary records poses minimal risk even if misused by an AI agent.
