Tools, Tasks & Workflows

Build complex multi-agent workflows

Master tools, tasks, and workflows by building a restaurant ordering system with greeter, order taker, and feedback agents.

What You Build

Restaurant ordering system: greeter→order taker→feedback. Multi-agent workflow with handoffs, TaskGroups, prebuilt tasks.

Prerequisites

→Course 1.1

Chapters

Workflow architecture

15m

When to use agents, tasks, or tools — and how they compose into workflows.

Agents vs tasks vs toolsWorkflow patterns

Building the greeter agent

15m

Build the greeter agent with on_enter() and tool-based handoff to the order taker.

Complex tool definitions

20m

Beyond decorators: programmatic tools, raw JSON schema, Toolset management, and ToolFlag options.

AgentTask: structured data collection

25m

Use AgentTask with typed results for structured data collection and form-like interactions.

TaskGroup: multi-step flows

25m

Orchestrate multi-step flows with TaskGroup, handle regression, and summarize context between steps.

Prebuilt tasks

15m

Use LiveKit's prebuilt tasks for common data collection patterns.

Agent handoffs & context

20m

Hand off between agents while preserving context, using on_exit() and AgentConfigUpdate.

State with userdata

15m

Manage cross-agent state with session.userdata for persistent conversation data.

Dynamic tool management

15m

Add, remove, and update tools and instructions dynamically based on conversation state.

Testing the workflow

20m

Test multi-agent workflows with is_agent_handoff() assertions and CI integration.

What You Walk Away With

Deep understanding of when to use tools vs tasks vs agent handoffs, plus a working multi-agent restaurant ordering system.
