The definition's `prompt` field, which holds the agent's instructions, may now be empty without the definition being rejected. The checks on `description`, `model` and the other fields are unchanged.\n\n**Why**\n\nAn agent definition with no instructions text now loads instead of failing validation.\n\n- Area: Agents\n- Tier: You'll notice\n- Useful: 2\/5\n- Signal: 1\/5"}
