WHY IT NEEDS A POLICY

Why task_accept needs a policy

This tool accepts a delegation/task offer, which creates or modifies state (accepting a task assignment) in a reversible way. It does not delete data, execute code, or move money. It is a Write action — committing the agent to a delegated task — with medium severity since misuse could cause the agent to accept unintended tasks or workloads across the public internet communication layer.

From the tool's definition "Terima delegation offer yang ditujukan ke agent ini" (Accept a delegation offer directed to this agent)
