Fetch the list of latest submissions made by the authenticated user.
AI agents call list_my_submissions to retrieve information from Online Judge MCP Server 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 submission history for the authenticated user. It performs a read-only operation with no capability to modify, delete, or execute code. The data returned is scoped to the user's own submissions, limiting potential exposure. The action is non-destructive and has minimal blast radius if misused by an AI agent.
