Create an agent

Create a managed agent from the Fleet page, give it an identity and first instructions, and start it.

After reading this page you will be able to:
  • Create a managed agent with an id, display name and tags
  • Know which fields can change later and which cannot
  • Create the same agent with the API

Prerequisites

  • The admin or owner role, or a custom role that grants agent creation.
  • At least one LLM provider, if the agent will call a model. See LLM providers.

Steps

  1. Open Agents › All agents and choose + Create agent (or go to /agents/create).
  2. Choose Managed by Liyagent. The type is fixed once the agent is created.
  3. Fill in the form. Managed agents have six sections, and two optional ones under collapsed headings:
    SectionNotes
    01 IdentityName and Description. The Agent id is made from the name (lowercase letters, digits and hyphens). A taken id gets a number. It is the agent's permanent key: budgets, policies and the audit log address it, and it cannot be changed later.
    02 ModelThe provider and model it reasons with, from this instance's connected providers, or the instance default backend.
    03 InstructionsIts system prompt, in Markdown. Start from a template or write your own, and edit it later on the agent's Settings tab.
    04 ToolsThe MCP servers it may call. You can attach more later.
    05 AccessWho may use it: the access policy created with it.
    06 TagsUnder Advanced: key=value, comma-separated. Usage and cost reports can be broken down by tag. An instance can require some tags.
    07 LimitsUnder Limits, optional. The Context window (the input tokens one step may send, 1,024 to 2,000,000; blank is the smaller of the model's window and 32,000), the Step cap (model calls per request) and the Run limits (wall-clock deadline, tool calls, delegations, identical tool calls, token and USD ceilings per run). Blank keeps the default.
    08 Sub-agentsUnder Sub-agents, optional. Helpers the agent delegates to, each with a description (what the agent reads to decide to use it), instructions, the context it is handed, a model and provider override, its MCP servers, and its own Context window, Reply cap, Step cap and Run limits, none above the parent's. A registered agent can be added as a sub-agent too: it then runs as itself.
  4. Choose Create agent. One submit creates the agent, its model binding, its runtime (MCP servers, limits and sub-agents) and its access policy. If a step fails, the agent is deleted again so nothing is left half-made.
  5. The agent opens on its own page with a Set up checklist above its tabs: context window reviewed, guardrails applied, connected to a channel (Teams, Google Chat, Slack, email or web chat; people who may chat with it already find it in the workspace), sub-agents added (optional) and tested in the Playground. An item clears as soon as the data says so; Dismiss hides the card in your browser. Start the agent from there, and refine it on Settings (see Instructions and model).
Note

Choose Self-managed instead when the agent's code runs on your infrastructure. It then gets a credential and calls the gateway. See Set up your agent.

With the API

curl -X PUT https://<host>/api/gateway/agents/hr-helper \
  -H "Authorization: Bearer $TOKEN" -H "Content-Type: application/json" \
  -d '{"label":"HR helper","about":"Answers HR policy questions",
       "runtime":"managed","prompt":"You answer questions about the HR handbook.",
       "tags":["team=hr"]}'

tags is a list of key=value strings. Bind its model with PUT /api/agents/hr-helper and attach tools with PUT /api/agents/hr-helper/runtime. Other agent routes: GET /api/gateway/agents, GET, PATCH and DELETE /api/gateway/agents/{agent_id}.
