What shortest_valid_path does on Nodebench

AI agents call shortest_valid_path to retrieve information from Nodebench without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Why shortest_valid_path is rated Low

This tool queries or computes a path based on a stated objective and returns the result. It has no side effects: it does not create, modify, delete, execute code, or trigger external operations. The returned path is informational guidance, not an action executed by the tool itself. This fits the 'Read' category as a retrieval/query operation.

From the tool's definition Tool name and description indicate it 'Return[s] the shortest valid workflow path' — a read operation that retrieves or queries data about workflow paths without modifying, executing, or deleting anything.

{
  "version": "1",
  "default": "deny",
  "tools": {
    "shortest_valid_path": {}
