Chatting with an agent ​

The model picker with agent entries listed below the models
Agents appear in the picker

Instead of a plain model, you can chat with one of your agents. An agent brings its own instructions, skills, tools and knowledge to every turn — so it's a specialist you can talk to.

Make an agent available in chat ​

On the Agents page, open an agent and turn on Use in Secure Chat (or press Chat with this agent, which enables it and opens a fresh conversation with the agent pre-selected). It then shows up in the chat model picker under its own name.

What's different from a plain model ​

  • The agent answers with its system prompt and skills, not the generic chat prompt.
  • It can call the tools it's been granted and consult its knowledge base.
  • It can delegate to sub-agents if it's configured to.

Because tools and knowledge require niil's runtime, an agent-in-chat turn will tell you clearly if the runtime is unavailable rather than silently answering without its tools.

Multi-turn ​

Agent conversations keep their full history, so you can have a back-and-forth and the agent remembers the context of the chat.
