Learn to create agents in RΞASON
An agent is just a LLM that selects which action to take from predefined pool of actions in order to accomplish a certain objective.

actions.
To create an agent in RΞASON you’ll need to define its actions and then the agent itself.

agent.reason()
is an async generator that you iterate using for await (const step of agent.reason()) {}

, you decide if you want to call agent.stop()
to stop the agent or not. In this case we’re stopping the agent if:

POST
request with a input
property in the body. That means your entrypoint needs to read it and pass it to your agent.memory_id
automatically.
But what is memory_id
?
memory_id
useAgent()
a new memory_id
is created;useAgent(memory_id)
again you can pass a memory_id
and that agent will be continue where it left off.database.sqlite

Let’s test this out:
Using `memory_id`
memory_id
works under the hood. However, as long as your entrypoint is expecting a memory_id
property inside the request’s body, chat mode will automatically send the memory_id
.
