Agent handoff is a multi-agent software pattern that transfers an active task, its relevant context, and responsibility for the next response to another AI agent. It lets a specialist agent take over when it is better suited to complete a task, while preserving clear control, state, and security boundaries.
Agent Handoff
What Is Agent Handoff in Agentic AI?
Agent handoff is a software pattern where one AI agent transfers an active task and relevant context to another agent that takes responsibility for the next step. Unlike passing a message, a handoff changes which agent is in control.
How an Agent Handoff Works
A reliable transfer follows a defined sequence.
- Identify the task intent and current state.
- Select a qualified specialist agent.
- Send only the context it needs.
- Check inputs and permissions.
- Let the recipient execute or escalate.
- Return a result, status, or next action.
For example, a planning agent can hand implementation requirements to a code agent, then receive a test-ready feature summary.
Agent Handoff vs. Routing vs. Using an Agent as a Tool
| Pattern | Control | Best use |
|---|---|---|
| Routing | Selects a destination | Choosing the right agent |
| Handoff | Recipient takes over | Specialist-led task completion |
| Agent as a tool | Caller stays in control | Bounded research or actions |
Benefits of Agent Handoffs
Well-designed handoffs make multi-agent workflows easier to manage.
- Assign work to specialized agents.
- Keep prompts and responsibilities smaller.
- Reuse clear workflow stages.
- Separate permissions by task.
Practical Limits of Agent Handoffs
More agents do not automatically make a system more reliable.
- Missing context can cause incorrect work.
- Unclear rules can create loops or conflicts.
- Each transfer can add latency and cost.
- Broad credentials increase security risk.
Design Checklist for Reliable Handoffs
Use a structured task contract, clear entry criteria, and explicit return rules.
- Transfer the minimum useful state, including relevant agent memory.
- Scope recipient credentials to the required action.
- Log each transfer and test failed routes.
- Define when sub-agents must return control.

What is agent handoff?
Agent handoff transfers an active software task, relevant context, and responsibility from one AI agent to another.
What is handoff in agentic AI?
In agentic AI, a handoff lets a specialist agent take control when it is better suited to perform the next task step.
Are handoffs and routing the same in AI agents?
No. Routing chooses an agent or destination. A handoff transfers task ownership and responsibility to that agent.
When should an AI system use an agent handoff instead of an agent as a tool?
Use a handoff when the specialist should own the next interaction or workflow stage. Use an agent as a tool when the calling agent needs a limited result and should retain control.
What information should an agent handoff include?
Include the goal, relevant task state, constraints, allowed actions, required inputs, and a clear completion or escalation rule. Do not send unnecessary history or credentials.
