ChatBot.guardrail()

Add a guardrail to the chatbot’s validation pipeline.

Usage

Source

ChatBot.guardrail(guard)

Guards run in the order they are added. Input guards validate user messages before the LLM sees them. Output guards validate LLM responses before they are returned to the user. If any guard blocks a message, the pipeline short-circuits.

Parameters

guard: Guard

A Guard instance, typically created by @tb.guardrail, or one of the built-in guard factories (tb.no_pii(), tb.max_response_length(), etc.).

Returns

ChatBot

The same instance for method chaining.

Examples

import talk_box as tb

bot = (
    tb.ChatBot()
    .guardrail(tb.no_pii())
    .guardrail(tb.max_response_length(500))
    .guardrail(tb.disclaimer_required("Not financial advice."))
)
