tone_check()

Guard that flags responses not matching the expected tone.

Usage

Source

tone_check(
    expected_tone,
    *,
    indicators=None,
)

Uses keyword-based heuristics to detect tone mismatches. For production use with high accuracy, consider extending with an LLM-based judge.

Parameters

expected_tone: str

The desired tone (e.g., "professional", "casual", "formal").

indicators: dict[str, list[str]] | None = None

Optional mapping of tone names to indicator words/phrases. If not provided, uses built-in defaults for common tones.

Returns

Guard

A configured tone-checking guard (output-only).

Examples

bot = tb.ChatBot().guardrail(tb.tone_check("professional"))
