AI can be probabilistic. Your boundaries don’t have to be.

Agents are being trusted to send messages, move money, change access, update records, and touch production systems. The authority you give them should be explicit before the action happens.

human review

Manager review

The workflow is paused at this action. The rest of the agent state is preserved.

Paused for managerThe agent waits only at the action that needs judgment.

OUTCOME

Policy evaluatedYES

Decision retainedYES

Workflow resumes when allowedYES

Control without turning every action into an approval.

Routine work stays automatic. Only the action that crosses a review boundary pauses for a person.

Policy → executable rules

Your policy should work as hard as your agents do.

Turn plain-language policy into proposed tools, runtime rules, review paths, and evidence requirements. Review the controls, publish them, and give agents a machine-readable boundary they can actually follow.

ESCALATE

Runtime governance

Govern the action, not the whole workflow.

Manage the full review lifecycle, from an agent’s proposed action to policy evaluation, reviewer routing, approval, and audit evidence. Stacksona Gate adds this control to the agent stack you already use.

01 / PROPOSE

The agent reaches a tool or action.

Send the proposed action and the context needed to evaluate it.

02 / ENFORCE

Stacksona executes the applicable rules.

Allow it, reject it, modify it, or route it to the right person for review.

03 / CONTINUE

The agent keeps working when permitted.

Approved actions resume with the decision, policy result, and outcome retained as evidence.

Your agents stay yours

Your agents stay yours. The final say stays with you.

Keep the agents, tools, models, and orchestration you already use. Add policy and human judgment immediately before the actions that need control.
