List upcoming events and assignment due dates across all courses, soonest first.
AI agents call list_upcoming_events to retrieve information from PokeCanvas without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries calendar events and assignment due dates without modifying, deleting, or executing any operations. It has no side effects beyond information retrieval. Severity is low because the blast radius of misuse is minimal—an AI agent could only over-query the API or retrieve data it already has access to within the Canvas course system, with no destructive or financial consequences.
From the tool's definition Tool name 'list_upcoming_events' and description 'List upcoming events and assignment due dates across all courses' indicate retrieval only. The verb 'List' and lack of language indicating modification, deletion, or execution confirm read-only behavior.
