agent-graphs

launchdarkly/ai-tooling

Create and manage directed graphs of agent configs with handoff logic for multi-agent workflows.

What is agent-graphs?

Agent graphs let you design multi-agent systems as directed graphs where nodes are configs and edges define routing with handoff data. Use this when building workflows where multiple specialized agents need to coordinate and pass context to each other.

  • Design and create directed graphs with configs as nodes and routing edges
  • Define handoff data to control context passing between agents
  • Set a root config as the entry point for user input
  • List and inspect existing graphs in your project
  • Update graph topology and edges without recreating
  • Delete graphs when no longer needed

How to use agent-graphs

  1. 1.Design your graph topology on paper: identify agents, routing paths, and handoff data
  2. 2.Verify all config nodes exist using get-ai-config; create missing configs with create-ai-config
  3. 3.Call create-agent-graph with projectKey, graph key, name, rootConfigKey, and edges array
  4. 4.Use get-agent-graph to verify the graph structure and edge connections
  5. 5.Update edges with update-agent-graph if topology changes are needed
  6. 6.Test end-to-end routing to confirm agents hand off correctly

Use cases

Good for
  • Build customer support triage systems that route queries to specialist agents
  • Create multi-step processing pipelines (extract → transform → validate → store)
  • Implement escalation chains (L1 support → L2 support → human handoff)
  • Design intent-based routers that dispatch to different specialized agents
  • Orchestrate complex workflows where agents hand off work based on context
Who it's for
  • AI engineers building multi-agent systems
  • Product teams designing agent-based workflows
  • DevOps/platform engineers managing agent infrastructure
  • Teams using LaunchDarkly for agent configuration

agent-graphs FAQ

What's the difference between a node and an edge?

Nodes are configs (agents with models, prompts, and tools). Edges are connections between configs that define routing and carry handoff data from source to target.

Can I have circular routing in my graph?

Yes, circular routing is allowed, but you must ensure agents have termination conditions to avoid infinite loops.

What if a config node doesn't exist yet?

Create it first with create-ai-config before referencing it in the graph. All nodes must exist before the graph can be created.

How do I pass context between agents?

Define handoff data on edges — this data is passed from the source config to the target config during the transition.

Can I modify a graph after creating it?

Yes, use update-agent-graph to modify edges, root config, or description without deleting and recreating.

Config Agent Graphs

You're using a skill that will guide you through creating and managing agent graphs in LaunchDarkly. Your job is to design the graph topology, create it with the right edges and handoffs, and verify the routing between config nodes.

Prerequisites

This skill requires the remotely hosted LaunchDarkly MCP server to be configured in your environment.

Required MCP tools:

  • create-agent-graph -- create a new graph with nodes and edges
  • get-agent-graph -- inspect a graph's structure and edges
  • list-agent-graphs -- browse existing graphs in the project

Optional MCP tools:

  • update-agent-graph -- modify edges, root config, or description
  • delete-agent-graph -- permanently remove a graph
  • get-ai-config -- inspect individual configs that serve as nodes
  • create-ai-config -- create new configs to use as graph nodes

Core Concepts

What Are Agent Graphs?

An agent graph is a directed graph where:

  • Nodes are configs (each config is an agent with its own model, prompt, and tools)
  • Edges define routing between configs (source -> target)
  • Handoff data on edges controls how context is passed between agents
  • Root config is the entry point — the first agent that receives user input

When to Use Agent Graphs

ScenarioExample
Multi-step workflowsTriage agent -> Specialist agent -> Summary agent
Routing by intentRouter agent decides which specialist handles the request
Escalation chainsL1 support -> L2 support -> Human handoff
Pipeline processingExtract -> Transform -> Validate -> Store

Graph Structure

[Root Config] --edge--> [Config A] --edge--> [Config C]
                  \--edge--> [Config B]

Each edge has:

  • key -- unique identifier for the edge
  • sourceConfig -- the config key that routes FROM
  • targetConfig -- the config key that routes TO
  • handoff (optional) -- data/instructions passed during the transition

Core Principles

  1. Design Before Building: Map out nodes and edges on paper/whiteboard first
  2. One Agent, One Job: Each node should have a clear, focused responsibility
  3. Root Config Is the Router: The entry point should understand how to dispatch
  4. Handoff Data Matters: Define what context flows between agents
  5. Verify the Full Path: Test that routing works end-to-end

Workflow

Step 1: Design the Graph

Before creating anything:

  1. Identify the agents (configs) needed — each is a graph node
  2. Map the routing: which agent hands off to which?
  3. Define handoff data: what context does each edge carry?
  4. Identify the root config: which agent receives initial input?
  5. Check existing graphs with list-agent-graphs to avoid duplicates
  6. Check existing configs with get-ai-config to see what nodes already exist

Step 2: Ensure Nodes Exist

Each node in the graph must be an existing config. If configs don't exist yet:

  1. Use create-ai-config to create each agent config
  2. Set up variations with appropriate models and prompts for each agent's role
  3. Verify each config exists with get-ai-config

Step 3: Create the Graph

Use create-agent-graph with:

  • projectKey -- the project containing the configs
  • key -- unique identifier for the graph
  • name -- human-readable display name
  • description (optional) -- explain the graph's purpose
  • rootConfigKey -- the entry-point config key
  • edges -- array of connections between configs
{
  "projectKey": "my-project",
  "key": "support-triage-graph",
  "name": "Customer Support Triage",
  "description": "Routes customer queries to the appropriate specialist agent",
  "rootConfigKey": "triage-agent",
  "edges": [
    {
      "key": "triage-to-billing",
      "sourceConfig": "triage-agent",
      "targetConfig": "billing-specialist",
      "handoff": {"category": "billing", "priority": "normal"}
    },
    {
      "key": "triage-to-technical",

      "targetConfig": "technical-specialist",
      "handoff": {"category": "technical", "priority": "normal"}
    }
  ]
}

Step 4: Verify

  1. Use get-agent-graph to confirm the graph was created with the correct structure
  2. Verify edges connect the right source and target configs
  3. Check that the root config key matches the intended entry point
  4. Confirm handoff data is present on edges that need it

Report results:

  • Graph created with N nodes and M edges
  • Root config set correctly
  • All edges verified

Edge Cases

SituationAction
Config doesn't exist yetCreate it first with create-ai-config before referencing in a graph
Circular routingAllowed but warn user — ensure there's a termination condition in the agent logic
Single-node graphValid but unusual — consider if a graph is actually needed
Updating edgesUse update-agent-graph — provide the complete new edge list

What NOT to Do

  • Don't create a graph before the config nodes exist
  • Don't forget handoff data when agents need context from predecessors
  • Don't create overly complex graphs — start simple and add nodes as needed
  • Don't delete a graph without understanding if it's actively used in agent workflows
