Pre-release documentation. This guide describes the current product design and evaluation build. Packaging, availability and commercial terms may change before release.
Advisory versus enforced
A prompt, skill or optional tool is advisory because the model may ignore it. An enforced integration places a mandatory hook or gateway on the only path to the protected tool.
- Enforced: the check occurs before execution and the verdict is binding
- Advisory: the agent is instructed to ask but can bypass the instruction
- Deployment topology determines the real strength of the control
Decision shape
A gateway request supplies the actor, proposed capability, resource, purpose and relevant facts. Rulebook returns a structured verdict and the obligations needed to proceed.
request context
-> Rulebook decision
-> allow
-> deny
-> require approval
-> transform with obligations
-> protected tool executes only when authorizedIntegration patterns
- Native pre-tool hooks in agent SDKs
- A gateway proxy that wraps an MCP or HTTP tool surface
- Policy emission into a platform-native engine such as Cedar or Rego
- Required checks in CI and release workflows
