Create a ReAct module — react • dsprrr

Create a tool-using module that alternates reasoning with tool calls. Tool use is explicit: passing tools to module() never changes a prediction module into a ReAct agent.

Usage

react(
  signature,
  tools = list(),
  max_iterations = 10L,
  chat = NULL,
  template = "",
  demos = list(),
  config = list(),
  ...
)

Arguments

signature: A Signature object or string notation defining inputs and outputs.
tools: A list of ellmer ToolDef objects.
max_iterations: Maximum number of tool-call iterations.
chat: Optional ellmer Chat object.
template: Optional glue template for prompt generation.
demos: Optional list of demonstration examples.
config: Optional prediction configuration.
...: Must be empty.

Value

A ReactModule executed with run().

Examples

agent <- react(
  "question -> answer",
  tools = list(),
  max_iterations = 10
)
