They are useful documentation, not an external certification of a deployment.\n\nAn agent that can read the CRM and send email needs a control layer that can deny a destructive call even when the model insists it is correct. This toolkit moves that decision out of the prompt and into code, then leaves a record of what policy allowed or blocked it. For a lean GTM team, the practical starting point is smaller than the repo's full architecture: gate the few high-risk tools, log every decision, and add identity or sandboxing when multiple agents and users start sharing the same credentials. Public preview and breadth are the tradeoffs; adopt the piece your threat model needs, not the whole diagram."
