Simple Agent

A minimal Orca project with one model, one tool, and one agent.

Source (main.oc)

model gpt4 {
  provider    = "openai"
  model_name  = "gpt-4o"
  temperature = 0.7
}

tool search {
  name = "web_search"
  desc = "Search the web for current information"
}

agent researcher {
  model   = gpt4
  persona = "
    You are a research assistant.
    You search the web for information and
    provide well-sourced answers.

    Always cite your sources.
    "
  tools   = [search]
}

What's happening

1. The model block creates a ChatOpenAI instance with GPT-4o and temperature 0.7.
2. The tool block defines a web search tool the agent can use.
3. The agent block wires the model and tool together with a persona that describes the agent's behavior.
