set_functions | SignalWire

Set which SWAIG functions are available during this step. Restricting functions per step prevents the AI from calling irrelevant tools.

Parameters

functions

str | list[str]Required

Either "none" to disable all functions, or a list of function names to allow.

Returns

Step — Self for method chaining.

Example

1 from signalwire import AgentBase
2 
3 agent = AgentBase(name="my-agent", route="/agent")
4 
5 contexts = agent.define_contexts()
6 ctx = contexts.add_context("default")
7 greet = ctx.add_step("greet")
8 greet.set_text("Welcome the caller.")
9 greet.set_functions("none")
10 verify = ctx.add_step("verify")
11 verify.set_text("Verify the caller's identity.")
12 verify.set_functions(["lookup_account", "verify_identity"])
13 
14 agent.serve()
