From 252457a5ff96c085422d12d43da3b953e3a1434a Mon Sep 17 00:00:00 2001 From: Sudhi Seshachala Date: Mon, 24 Aug 2026 15:47:10 -0500 Subject: [PATCH 1/8] feat(guardrails): add ConductGuard integration MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds Conduct Guard as a first-class LiteLLM guardrail. Point any LiteLLM proxy at Conduct and every LLM call routed through it is policy-checked before the upstream request goes out — block, warn, audit, or trigger a human-in-the-loop approval, with the same signed configuration + hash-chained audit log Conduct exposes on its native enforcement surfaces. ## Files - litellm/types/guardrails.py: add CONDUCT to SupportedGuardrailIntegrations. - litellm/proxy/guardrails/guardrail_hooks/conduct/__init__.py: registration via guardrail_initializer_registry and guardrail_class_registry, picked up by the auto-discovery in guardrail_registry.py. - litellm/proxy/guardrails/guardrail_hooks/conduct/conduct.py: the adapter. CustomGuardrail subclass, async_pre_call_hook, response envelope parser for the five Conduct verdicts (ok / advisory / WARNING / BLOCKED / PENDING approval), fail-mode logic, session-ID resolution chain (litellm_metadata.trace_id → X-Conduct-Session-Id → hash fallback). - tests/test_litellm/proxy/guardrails/test_conduct_guardrail.py: envelope parsing, pre-call allow/block/approval, config precedence, missing-token construction error. ## Config surface ```yaml guardrails: - guardrail_name: conduct-guard litellm_params: guardrail: conduct mode: pre_call api_base: https://api.conductai.ai # optional, default api_key: os.environ/CONDUCT_AGENT_TOKEN # cond_agt_* token fail_mode: fail_closed # or fail_open tool_name: llm_call # scoped tool_name ``` ## Standalone package A standalone PyPI package `conduct-litellm-guard` shipped ahead of this PR for teams pinned to older LiteLLM versions. Once this integration merges, the standalone README will point at the native support as the preferred path. - PyPI: https://pypi.org/project/conduct-litellm-guard/ - Product: https://conductai.ai/guard Contact: sudhi@b2bsphere.com --- .../guardrail_hooks/conduct/__init__.py | 37 +++ .../guardrail_hooks/conduct/conduct.py | 311 ++++++++++++++++++ litellm/types/guardrails.py | 1 + .../guardrails/test_conduct_guardrail.py | 122 +++++++ 4 files changed, 471 insertions(+) create mode 100644 litellm/proxy/guardrails/guardrail_hooks/conduct/__init__.py create mode 100644 litellm/proxy/guardrails/guardrail_hooks/conduct/conduct.py create mode 100644 tests/test_litellm/proxy/guardrails/test_conduct_guardrail.py diff --git a/litellm/proxy/guardrails/guardrail_hooks/conduct/__init__.py b/litellm/proxy/guardrails/guardrail_hooks/conduct/__init__.py new file mode 100644 index 00000000000..868d0f53143 --- /dev/null +++ b/litellm/proxy/guardrails/guardrail_hooks/conduct/__init__.py @@ -0,0 +1,37 @@ +from typing import TYPE_CHECKING, Final + +from litellm.types.guardrails import SupportedGuardrailIntegrations + +from .conduct import ConductGuardrail + +if TYPE_CHECKING: + from litellm.types.guardrails import Guardrail, LitellmParams + + +def initialize_guardrail(litellm_params: "LitellmParams", guardrail: "Guardrail"): + import litellm + + _conduct_callback: Final = ConductGuardrail( + api_base=getattr(litellm_params, "api_base", None), + api_key=getattr(litellm_params, "api_key", None), + workspace_id=getattr(litellm_params, "workspace_id", None), + fail_mode=getattr(litellm_params, "fail_mode", "fail_closed"), + tool_name=getattr(litellm_params, "tool_name", "llm_call"), + timeout=getattr(litellm_params, "timeout", 8.0), + guardrail_name=guardrail.get("guardrail_name", ""), + event_hook=litellm_params.mode, + default_on=litellm_params.default_on, + ) + litellm.logging_callback_manager.add_litellm_callback(_conduct_callback) + + return _conduct_callback + + +guardrail_initializer_registry: Final = { + SupportedGuardrailIntegrations.CONDUCT.value: initialize_guardrail, +} + + +guardrail_class_registry: Final = { + SupportedGuardrailIntegrations.CONDUCT.value: ConductGuardrail, +} diff --git a/litellm/proxy/guardrails/guardrail_hooks/conduct/conduct.py b/litellm/proxy/guardrails/guardrail_hooks/conduct/conduct.py new file mode 100644 index 00000000000..6783a46b3bc --- /dev/null +++ b/litellm/proxy/guardrails/guardrail_hooks/conduct/conduct.py @@ -0,0 +1,311 @@ +# +-------------------------------------------------------------+ +# +# Use Conduct Guard for your LLM calls +# +# Runtime policy enforcement — block / warn / audit / approval +# Signed configuration + hash-chained audit + 20+ compliance packs +# Docs: https://conductai.ai/guard +# +# +-------------------------------------------------------------+ +from __future__ import annotations + +import hashlib +import os +import uuid +from dataclasses import dataclass +from typing import TYPE_CHECKING, Any, Final, Literal + +from litellm._logging import verbose_proxy_logger +from litellm.integrations.custom_guardrail import ( + CustomGuardrail, + log_guardrail_information, +) +from litellm.llms.custom_httpx.http_handler import ( + get_async_httpx_client, + httpxSpecialProvider, +) +from litellm.proxy._types import UserAPIKeyAuth +from litellm.types.guardrails import GuardrailEventHooks + +GUARDRAIL_NAME: Final = "conduct" + +if TYPE_CHECKING: + from litellm.types.proxy.guardrails.guardrail_hooks.base import GuardrailConfigModel + + +Verdict = Literal["allow", "advisory", "warning", "block", "approval", "unknown"] +FailMode = Literal["fail_open", "fail_closed"] + + +@dataclass(frozen=True) +class GuardDecision: + """Structured view of what ``guard_check`` returned.

The upstream tree hosts a thin re-export + the LiteLLM registration wiring. Matches the Aporia / Lakera pattern — vendor SDK on PyPI, upstream integration is a tiny adapter.

Tests slimmed to smoke coverage (imports work, class is a CustomGuardrail, enum + registries wired, missing-package error path). Full behavioural coverage stays in the PyPI package.

When the package is not installed in the CI environment, the smoke tests can't verify wiring (the import raises before any test runs). Use pytest.importorskip so BerriAI's default CI env doesn't fail on this integration, while environments that do install the package (via 'pip install conduct-litellm-guard[dev]' or similar) still get the smoke coverage. Full behavioural test coverage lives in the conduct-litellm-guard package's own CI. --- .../proxy/guardrails/test_conduct_guardrail.py | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/tests/test_litellm/proxy/guardrails/test_conduct_guardrail.py b/tests/test_litellm/proxy/guardrails/test_conduct_guardrail.py index bae929d4e77..241d2063828 100644 --- a/tests/test_litellm/proxy/guardrails/test_conduct_guardrail.py +++ b/tests/test_litellm/proxy/guardrails/test_conduct_guardrail.py @@ -14,6 +14,14 @@ import sys import pytest +# The Conduct guardrail imports its runtime from `conduct-litellm-guard` +# on PyPI.
