Create an agent

Walk from an empty Create-agent dialog to a published agent — pick the model, write instructions, bind knowledge, toggle tools, and verify in Chat.

5 min read

This tutorial walks from an empty Create agent dialog to an agent you publish and use. The result is a working agent that knows its domain, has the tools to act on what it reads, and is reachable from any chat in your org. About fifteen minutes if you have a model provider already configured; longer if you also have to set one up.

You need the Editor role or higher and a model provider configured under Settings > Providers; the first prerequisite below links the setup walkthrough if you do not. The voice this tutorial uses is the same voice the Agent concepts page builds — read that page once before you write your first agent's instructions.

Before you begin

Make sure two things are in place:

  • A model provider is configured under Settings > Providers. Cloud users get one by default; self-hosted users follow Configuration → providers.
  • You hold the Editor role or higher in this org. Check Settings > People if you are not sure; the role is on your member row.

The tutorial uses a support-triage agent as the running example — the same one Agent concepts introduces. Substitute your own domain freely; the steps do not depend on the example.

Step 1 — Pick the primary model

Open Agents in the sidebar and click Create agent. The dialog drops you on the Instructions & model tab. Open the model picker and the search field expects a model name or family — type "gpt", "claude", or "llama" to filter. Pick a capable model for the primary; the agent's behaviour leans heavily on this choice. The picker also exposes a fallback slot — pick a smaller, cheaper model so the agent keeps running when the primary is rate-limited.

Step 2 — Write the instructions

The instructions field is plain markdown. Three pieces of advice from the field:

  • Open with the voice. One paragraph naming who the agent is, who it answers to, and what tone it strikes. The model treats this as the strongest signal.
  • Name the refusal cases explicitly. Three or four sentences that say what the agent declines to do and what it says when it declines.
  • Resist the temptation to specify every behaviour. Long instructions get diluted in long conversations. If a behaviour belongs in code, lean on a tool; if it belongs in data, lean on knowledge.

Save the agent with the Save button at the top right. The dialog stays open with the agent's ID visible in the URL — you can come back to refine.

Step 3 — Bind knowledge sources

Switch to the Knowledge tab. Knowledge is what the agent can look at; nothing is bound by default. Click Agent knowledge and pick from the org's documents, customers, products, vendors, or websites. The agent will retrieve from these sources at reply time and cite what it used.

Two cautions:

  • Bind the smallest useful set. A document bound but rarely retrieved still costs embedding cycles.
  • Knowledge bound here is in addition to anything an agent's instructions tell it to retrieve directly. The instructions name the policy; the binding names the surface.

Step 4 — Toggle the tools

Switch to the Tools tab. Tools are what the agent can do beyond generating text. The toggles are grouped by family — web, files, RAG, run code, sub-agents, workflows, MCP, integrations, human input. Toggle on what the agent needs and leave the rest off. Every toggle widens the trust boundary, so be parsimonious.

The toggles that need particular thought:

  • Run code is gated by the org's run-code policy. If your org policy disallows it, the toggle reads as disabled.
  • Sub-agents lets this agent delegate to others; Agent delegation covers when that is the right move.

Step 5 — Publish and try it

Back on Instructions & model, flip Visible in chat on and click Save. A toast confirms Agent saved. Open a new chat, pick the agent from the picker, and send a message that exercises the knowledge and tools you bound. If the agent answers the way you wrote it to, you are done; if it does not, the History tab on the agent shows every change you have made and lets you compare or restore.

Troubleshooting

  • Save is greyed out. The instructions field is empty or the model picker has no selection. Both are required.
  • Agent does not appear in the chat picker. Confirm Visible in chat is on. If it is, confirm the user picking the agent has access to it — Project agents do not appear outside their Project.
  • Replies say "no access" to a tool. A governance policy is gating the tool. The agent definition allows it; the runtime is refusing. Check Policies and limits.
  • Retrieval returns nothing. The knowledge sources you bound may not contain what the prompt asked for. Verify the source is indexed by opening it from Documents and confirming the chunks render.

Where this gets used

Creating one agent is the moment the rest of the platform starts to feel like Tale rather than a generic chat. The natural next walk is Agent with knowledge — same shape, but binds a folder of PDFs and exercises the citation pipeline end to end. If the agent you just built needs to hand off to a specialist, Delegate between agents is the chain pattern.
