Stacksona for Google ADK

Q: What statuses should my workflow allow?

Execute the gated action only on allow or approved. Stop, retry, notify, or route to fallback for every other state.

Add Stacksona checks before tools in an ADK agent take production, external, customer-facing, or destructive actions.

RecipeNo native package yetSurface: Tool callback or sidecar

Add Stacksona checks before ADK tools take production, external, customer-facing, or destructive actions. This page shows the recommended integration pattern using HTTP, a wrapper, or a small bridge service.

Start with this decision step

Every recipe should create a Stacksona decision before the platform executes the risky action.

pseudo

1. Agent prepares a risky action.
2. Platform calls Stacksona with action details.
3. If decision is allow or approved, execute the action.
4. If decision is pending_review, wait, poll, or resume through callback.
5. If decision is reject or rejected, do not execute.

Recommended pattern

Step	Description
Before tool	Wrap the tool with a decision request.
Policy	Send risk details and payload to Stacksona before execution.
Audit	Log proposed and executed events back to Stacksona.

Example

python

# Conceptual ADK tool wrapper.

def stacksona_gated_tool(tool_name, execute):
    def wrapper(args):
        decision = stacksona_request_decision({
            "taskId": args.get("task_id"),
            "workflowName": "Google ADK Agent",
            "taskLabel": f"{tool_name} request",
            "toolName": tool_name,
            "subject": f"Agent wants to run {tool_name}",
            "riskLevel": args.get("risk_level", "medium"),
            "payload": args,
        })
        if decision["status"] in ["allow", "approved"]:
            return execute(args)
        return {"ok": False, "status": decision["status"]}
    return wrapper

Decision handling

Status	Workflow behavior
`allow`	Continue immediately.
`reject`	Stop the action before execution.
`pending_review`	Pause, poll, or wait for callback. Continue only after approved.
`approved`	Execute the action. Validate token first when signed approval is required.
`rejected`	Do not execute. Route to fallback, manual task, or safe response.

Integration FAQ

Can I use Stacksona with Google ADK today?

Yes. Use the documented native package when one exists. Otherwise, use the REST API, HTTP module, webhook action, or a small Node sidecar with @stacksona/sdk.

Where should Stacksona sit in a Google ADK workflow?

Place Stacksona immediately before the action that sends, updates, deletes, refunds, posts, deploys, or calls a production API.

What statuses should my workflow allow?

Execute the gated action only on allow or approved. Stop, retry, notify, or route to fallback for every other state.
