Why remove_task_relationship is rated Critical
This tool irreversibly removes a relationship between tasks. While it doesn't delete the tasks themselves, removing a dependency or semantic link may be difficult or impossible to reconstruct, making it a Destructive operation. The blast radius is medium since it affects task graph integrity but not the tasks themselves.
From the tool's definition 'Remove a semantic relationship between tasks' — explicitly removes/deletes a relationship between tasks

The rule that runs remove_task_relationship safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Todos, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For remove_task_relationship, this is the rule to start with:
remove_task_relationship is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect Todos, apply this rule, and every remove_task_relationship call is checked against it from then on.
