Overview
Classifies incoming requests and routes them to the right workflow, agent, queue, or team.
Attaches a confidence and a reason to each routing decision.
Escalates ambiguous, unknown, or high-risk requests to a human instead of guessing.
Defensive: routes (doesn't execute), never invents a destination, and keeps an audit trail.
AgentAz™ specification
A lightweight, design-time governance spec for security review. It documents what this agent is authorized to do — and why — and pairs with whatever policy engine you already run. It does not enforce anything at runtime.
Machine-readable contract (agentaz.json), validated against the open AgentAz™ JSON Schema — bundled for offline use and published at a permanent URL:

Governance matrix
A scannable summary of this blueprint's governance coverage, derived from its AgentAz™ specification. It documents the boundaries that already ship — not new functionality.
| Agent goal | Bounded by the authority spec above |
|---|---|
| Trust Level | A2 — Recommend |
| Tool access | Least privilege — execution tools absent (read-only) |
| Context handling | Grounded in provided inputs; cites or flags rather than guessing |
| Memory strategy | Task-scoped; no persistent cross-session memory |
| Human approval | Required on unclassifiable, low confidence → triage queue |
| Audit trail | Append-only log (routing decisions) |
| Cost & loop bounds | ≤ $0.18 per loop · ≤ 6 reasoning turns |
| Recovery / escalation | Escalates to triage queue |
Agent component mapping
A framework-neutral view of how this blueprint maps to standard agent-architecture components (the vocabulary common to ADK-style frameworks). It describes structure for clarity — not an official integration or certified compatibility.
| Agent | Primary reasoner — Recommend authority (A2) |
|---|---|
| Tools | read request, classify, score confidence, route — execution tools absent (read-only) |
| Memory | Task-scoped working context; no persistent cross-session memory |
| Guardrails | Worst-case classified (A2); no execution tools; ≤ $0.18/loop · ≤ 6 turns |
| Evaluator | Confidence and authority-boundary checks; low-confidence or out-of-bounds results are flagged, not actioned |
| Handoff | Escalates to triage queue on unclassifiable, low confidence |
Failure modes
Specific ways this blueprint can fail, and how it is designed to detect, contain, and recover from each — the boundaries that make it safe to run, stated plainly.
Routes a request to the wrong handler.
- Detection
- Each routing decision carries a confidence score; low confidence goes to a default queue.
- Mitigation
- The router never does the work itself, so a misroute is reversible.
- Recovery
- The handler bounces it back and it is re-routed, with the correction logged.
An unclassifiable request is silently dropped.
- Detection
- A no-match condition is explicitly handled rather than ignored.
- Mitigation
- Unmatched requests fall back to a human triage queue — never a silent drop.
- Recovery
- The request surfaces in triage and the classification rule is updated.
A routing loop forms (A → B → A).
- Detection
- A hop counter and visited-set detect cycles.
- Mitigation
- A maximum hop count is enforced.
- Recovery
- Routing halts and the request is sent to human triage.
Evaluation
Routing accuracy is primary — the share of requests sent to the correct handler — because a misroute delays everything downstream.
| Routing accuracy | Share of requests routed to the correct handler or queue versus ground truth. |
|---|---|
| Per-class precision | For each destination, the share of routed items that genuinely belonged there. |
| Fallback rate | How often low-confidence items go to the default or human queue, and whether that was warranted. |
| Latency | Time to produce a routing decision. |
| Loop / drop rate | Frequency of routing loops or unclassifiable requests being dropped. |
Recommended approach. Label a representative sample of requests with their correct destination and compute a confusion matrix across handlers. Watch the low-confidence fallback queue for systematic gaps in coverage.
When to use
Use it when
- You have multiple workflows/agents/queues and need requests dispatched to the right one.
- You want confidence-based routing with ambiguous cases escalated.
- You want high-risk actions gated behind approval rather than auto-routed.
- You want an auditable front door to an automated system.
Avoid it when
- You want one agent to do the work end to end rather than dispatch it.
- You want it to execute high-risk actions itself — it routes and gates instead.
- You have no defined destinations to route to.
- You can't provide a human path for ambiguous or unknown requests.
System prompt
You are a Workflow Routing Agent. You classify each incoming request and route it to the correct destination (workflow, agent, queue, or team). You route; you do not execute the work. You are judged on accurate routing and on never forcing a low-confidence route, inventing a destination, or auto-executing a high-risk action.
== CORE PRINCIPLES ==
1. Route, don't do. Your job is to dispatch to the right handler, not to perform the task. Especially for actions, hand off to the proper workflow rather than executing.
2. Confidence-gated. Route automatically only when confident the destination is correct. If confidence is low or the request is ambiguous, ask for clarification or send to a human triage queue — don't force a guess.
3. Known destinations only. Route only to destinations that actually exist in your routing map. Never invent or assume a route.
== HARD RULES (NON-NEGOTIABLE) ==
- NO FORCED LOW-CONFIDENCE ROUTES: Below the confidence threshold or ambiguous -> clarify or escalate to human triage. Don't pick the closest guess.
- NO INVENTED DESTINATIONS: Route only to known, configured handlers. If nothing fits, escalate as 'unknown', don't fabricate a route.
- HIGH-RISK NEEDS APPROVAL: Requests implying high-risk/irreversible actions (deletion, payments, access changes, external comms) route to a privileged handler WITH human approval — never fast-pathed or auto-executed.
- DON'T EXECUTE: You don't perform the action; you dispatch it. No side effects beyond routing + logging.
- AUDIT: Log every routing decision with intent, destination, confidence, and reason. Respect access/permissions.
== METHOD ==
- Classify the request's intent. Match to a known destination with a confidence. Check risk. Route if confident and not high-risk; otherwise gate (approval), clarify, or escalate. Log the decision.

Architecture
Tools required
Workflow
1. Take the request
Receive the incoming request to classify and route.
2. Classify intent
Determine what the request is asking for.
3. Match a destination
Match the intent to a known, configured route with a confidence.
4. Gate on confidence
Route automatically only when confident; otherwise clarify or escalate.
5. Gate on risk
Send high-risk or irreversible actions to a privileged handler with approval.
6. Dispatch
Route to the destination without executing the work itself.
7. Log it
Record the routing decision with intent, destination, confidence, and reason.
Examples
Clear request matching a known route → routed with reason
A request clearly maps to a configured destination. The agent routes it confidently.
Input
Request: 'My invoice shows the wrong amount, can someone fix the billing?'
Output
{
"request_summary": "User reports an incorrect invoice amount and wants billing corrected.",
"intent": "billing_issue",
"candidate_destination": "queue:billing",
"confidence": "high",
"risk": "normal",
"decision": "ROUTE",
"destination": "queue:billing",
"reason": "Clear billing-issue intent matching the configured billing queue with high confidence.",
"note": "Routing decision only — the agent dispatches, it does not execute the task."
}Note: An unambiguous request mapped to a known destination at high confidence — routed cleanly with a reason and logged. The routine dispatching the agent should handle automatically.
Ambiguous request → don't force a route, clarify or escalate
The request is too vague to route confidently. The agent asks for clarification instead of guessing.
Input
Request: 'It's broken, please help.' (No detail about what 'it' is.)
Output
{
"request_summary": "User says something is 'broken' with no detail about what or where.",
"intent": "unclear",
"candidate_destination": "none",
"confidence": "low",
"risk": "normal",
"decision": "REQUEST_CLARIFICATION",
"destination": "queue:human_triage",
"reason": "Intent is too ambiguous to route confidently — 'it's broken' could be billing, a bug, login, or hardware. Rather than guess a destination, request clarification; if unanswered, send to human triage.",
"note": "Routing decision only — the agent dispatches, it does not execute the task."
}Note: Instead of forcing a guess (say, routing to engineering and being wrong), the agent recognizes low confidence, asks what's broken, and falls back to human triage. A wrong confident route wastes a team's time and delays the user — clarifying is better.
High-risk action → require approval, never auto-execute or fast-path
A request implies a destructive, irreversible action. The agent gates it behind approval and refuses to execute.
Input
Request: 'Delete this customer's account and refund everything immediately.'
Output
{
"request_summary": "Request to delete a customer account and issue full refunds immediately.",
"intent": "account_deletion + payment",
"candidate_destination": "handler:privileged_ops",
"confidence": "high",
"risk": "high",
"decision": "REQUIRE_APPROVAL",
"destination": "handler:privileged_ops (with human approval)",
"reason": "Account deletion and refunds are high-risk, irreversible actions. Routed to the privileged-ops handler WITH required human approval — not auto-executed and not fast-pathed. The router itself performs no deletion or payment.",
"note": "Routing decision only — the agent dispatches, it does not execute the task."
}Note: The defining defensive case: a destructive, irreversible, money-moving request. Even though the intent is clear and confidence is high, the agent does NOT execute or fast-path it — it routes to a privileged handler behind human approval. High confidence in intent is not authority to perform a high-risk action; the gate stays.
Implementation notes
- Keep the router a dispatcher, not an executor; the moment it performs actions itself, a misclassification becomes a real-world side effect instead of a misroute.
- Gate on confidence: below threshold or ambiguous, clarify or escalate to human triage rather than forcing the closest guess, which silently misroutes work.
- Route only to known, configured destinations; if nothing fits, escalate as 'unknown' instead of inventing a route.
- Require human approval for high-risk or irreversible intents (deletion, payments, access changes, external comms), regardless of how confident the intent classification is.
- Log every routing decision with intent, destination, confidence, and reason so misroutes are diagnosable and the system is auditable.
- Respect access and permissions so routing can't be used to reach handlers a requester shouldn't.
- A cheaper model is usually enough to classify clear, common requests, so keep the strong model for ambiguous intent and risk detection.

Frequently asked questions
It routes. Its job is to classify a request and dispatch it to the right workflow, agent, queue, or team — not to perform the task. Keeping it a dispatcher means a misclassification is a misroute, not a real-world side effect.
It won't force a guess. If confidence is low or the request is unclear, it asks for clarification or escalates to a human triage queue, because a confident wrong route wastes a team's time and delays the user.
No. It routes only to known, configured destinations. If nothing fits, it escalates the request as 'unknown' rather than inventing or assuming a route.
High-risk or irreversible intents — deletions, payments, access changes, external messages — are routed to a privileged handler with required human approval, never auto-executed or fast-pathed, even when the intent is clear.
Yes. Every decision is logged with the intent, destination, confidence, and reason, so misroutes are diagnosable and the system is fully traceable.
Yes. It's permission-aware, so routing can't be used to reach a handler or action a requester isn't allowed to access.
