Open **Settings**, select **Support Agent** under **Agents**, then **Guardrails**. Guardrails apply whenever the private agent acts on its own: when [private agent replies](/agents/private-agent-replies) are on, or when [payments](/agents/actions#payments) are set to **Issue**. Until one of those is on, the tab is locked and links you to where to turn them on. A tripped check holds the reply, and any payment action with it, as an internal note for your team. The [public agent](/agents/public-agent) is checked separately by its own [verifier](/agents/public-agent#every-answer-is-verified). The Guardrails tab ## Confidence Threshold Beyond the pass/fail checks, the verifier scores how confident it is that a reply is safe and complete. The agent only sends when that confidence is at or above your **Confidence threshold**, which is **80%** by default. Raise it to be more cautious. ## Always On These checks apply to every reply and can't be turned off: | Check | What it holds back | | - | - | | **Fabricated claims** | A claim that's contradicted by the evidence or can't be backed up | | **Unsupported promises** | A promise to take an action the agent can't actually take | | **Someone else's data** | Anything that exposes data belonging to anyone but the requester | | **Confidential disclosure** | Internal or confidential company information | ## Code or Log Lookups Turn on **Code or log lookups** to hold any reply where the agent read your code or queried your logs to write it. Use it when you'd rather a person review anything that came from internal systems. ## Your Checks Write your own conditions as sentences. Each check has a **Name** and a **Block auto-send when…** condition, for example *"the reply approves a refund over \$500"* or *"the reply commits to a specific delivery date."* You can add up to 20, and each has its own switch. The verifier also reads any [reply instructions](/agents/routing#reply-instructions) on the ticket's routing category, and holds a reply that ignores them.
