Trace agent runs. Guard proposed tool calls.

Staso helps teams to inspect and control the actions which your agent is about to take. We do this using rules and policies.

So in this case, user asked the agent to draft the email.

But agent used the tool called send email which was not supposed to happen. So our audit, our guard agent basically marked it as a violation because we were in audit mode. But the tool call still happened. Let's try it again with block mode.

It tried to use the send email tool call which we blocked and it was passed as a context. The send email action was blocked due to this rule violation.

So the agent was moved and agent basically then used the save draft tool.

We have two line integrations for SDKs like Anthropic, OpenAI and LiteLLM. We support coding agents as well like Claude Code or Codex. We have separate videos for each to help you integrate Staso.
