Create a supervisor graph that routes to workers

The supervisor agent decides which worker to invoke based on its response. Each worker's response is fed back to the supervisor for re-evaluation.

supervisor_graph() was renamed to graph_supervisor() in version 0.2.0 and is now deprecated.

Usage

graph_supervisor(supervisor, workers, max_iterations = 50L)

supervisor_graph(...)

Arguments

supervisor

An Agent object that decides routing. A system prompt suffix and a route tool are automatically injected.

workers

Named list of Agent objects.

max_iterations

Integer safety cap (default 50).

...

Arguments passed to graph_supervisor().

Value

A compiled AgentGraph object.

Details

The supervisor node sets state$next_worker via a routing tool that the supervisor calls. The routing condition reads this field to dispatch to the correct worker, or end the graph if the supervisor calls route("FINISH").

Examples

if (FALSE) { # \dontrun{
sup <- agent("boss", ellmer::chat_openai(model = "gpt-4o"))
w1 <- agent("coder", ellmer::chat_openai(model = "gpt-4o"))
w2 <- agent("tester", ellmer::chat_openai(model = "gpt-4o"))
graph <- graph_supervisor(sup, list(coder = w1, tester = w2))
} # }
