Use multiple guardrails in a single Guard object

You can use multiple guardrails in a single Guard object.

Install the necessary guardrails​

First, install the necessary guardrails:

guardrails hub install hub://guardrails/competitor_check
guardrails hub install hub://guardrails/toxic_language
guardrails hub install hub://guardrails/regex_match

Option 1: Chaining use methods​

You can chain the use methods to add multiple guardrails to a single Guard object. For example, here's how to make sure any LLM generated text doesn't contain any toxic language or any mention of your competitors:

from guardrails import Guard
from guardrails.hub import CompetitorCheck, ToxicLanguage, RegexMatch

competitors = ["Apple", "Samsung"]

guard = Guard().use(
    CompetitorCheck(competitors=[competitors])
).use(
    ToxicLanguage(
        validation_method=sentence,
        threshold=0.5)
).use(
    RegexMatch(regex="^[A-Z].*")
)

guard.validate("My favorite phone is BlackBerry.")  # Guardrail Passes

Option 2: Using the use_many method​

from guardrails import Guard
from guardrails.hub import (
    CompetitorCheck,
    ToxicLanguage,
    RegexMatch
)

competitors = ["Apple", "Samsung"]

guard = Guard().use_many(
    CompetitorCheck(
        competitors=[competitors]
    ),
    ToxicLanguage(
        validation_method=sentence,
        threshold=0.5
    ),
    RegexMatch(
        regex=^[A-Z].*
    )
)

guard.validate("My favorite phone is BlackBerry.")
