WHAT IT DOES

What jobs_list does on Yaver

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

RISK

Why jobs_list is rated Low

This tool queries the state of a job queue system, returning information about pending and dead-letter jobs. The action is purely informational (list/query) with no modifications, deletions, or external state changes. The blast radius of misuse is minimal—an agent could only gain visibility into queue status, which is a read-only concern.

From the tool's definition Tool name is 'jobs_list' and description states 'List pending queue + dead-letter jobs' — a retrieval operation with no data modification or side effects.

jobs_list Allowed

jobs_list is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
