AI agents call tool_cache_relevant_pages to retrieve information from Gradescope MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The name indicates a caching operation that retrieves and stores pages for reference, consistent with Read category behavior (no side effects). However, the empty description prevents higher confidence. If this tool were to modify grades, submissions, or rubrics, it would escalate to Write or Execute; destructive operations would be Destructive.
