AI agents call onpe_list_partidos to retrieve information from Onpe 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 electoral data (list of parties for the 2026 election rounds) with no side effects. It is a retrieval operation consistent with the 'Read' category. Severity is low because it exposes only public electoral information with no financial impact, no destructive capability, and no code execution. Confidence is high because the intent is explicitly to 'list' (list/retrieve) data.
