Add an LLM Agent Node directly to a DAG — dag_add_llm

Instantiates an AgentLLMNode and appends it to the provided AgentDAG in one step.

Usage

dag_add_llm_node(dag, id, role, driver, model = NULL, cli_opts = list(), ...)

Arguments

dag: AgentDAG. The graph object to which the node will be added.
id: String. Unique identifier for the node.
role: String. System prompt/role for the agent.
driver: AgentDriver. The LLM driver instance.
model: String. Optional model name override.
cli_opts: List. Optional CLI/API parameters.
...: Additional arguments. Passed to AgentLLMNode$new().

Value

The modified AgentDAG object (invisibly).

Examples

if (FALSE) { # \dontrun{
# Chaining nodes using the functional API
# This pattern is common in complex HydraR orchestration scripts.
dag <- dag_create() |>
  dag_add_llm_node(
    id = "writer",
    role = "Academic technical writer",
    driver = OpenAIAPIDriver$new(api_key = Sys.getenv("OPENAI_API_KEY"), model = "gpt-4-turbo")
  ) |>
  dag_add_llm_node(
    id = "critic",
    role = "Peer reviewer",
    driver = AnthropicAPIDriver$new(api_key = Sys.getenv("ANTHROPIC_API_KEY"), model = "claude-3-sonnet"),
    cli_opts = list(temperature = 0.2)
  )
} # }
