AI agents call luogu_resolve_problem to retrieve information from Luogu without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves problem details from Luogu — it resolves an identifier and fetches data. No side effects, modifications, or destructive actions are involved. Consistent with the server's stated read-only nature.
