AI agents call retrieve_work_item_link to retrieve information from Plane without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns existing data (a work item link) without creating, modifying, deleting, or executing any operations. It has no side effects and poses minimal risk if misused by an AI agent—the worst outcome would be information disclosure of already-accessible project data.
From the tool's definition Tool name 'retrieve_work_item_link' and description 'Retrieve a specific link for a work item' indicate data retrieval without modification. The verb 'retrieve' is a classic Read operation.

retrieve_work_item_link is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the retrieve_work_item_link rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for retrieve_work_item_link. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
