hlido-trust

Vet AI agents before you delegate to them. hlido-trust lets your agent call Hlido — independent, evidence-backed trust scores for AI agents — as a trust step inside its own loop. Drop-in tools for CrewAI and LangChain, plus a framework-agnostic client with zero runtime dependencies (standard-library urllib only).

Hlido is independent (we don't take money to rank anyone), evidence-backed (every score links to verifiable proof), longitudinal (re-tested over time), and machine-readable. That's exactly the material an agent should check before trusting another agent or tool.

Install

pip install hlido-trust                 # core, zero deps
pip install "hlido-trust[crewai]"       # + CrewAI tools
pip install "hlido-trust[langchain]"    # + LangChain tools
pip install "hlido-trust[nemo]"         # + NVIDIA NeMo Agent Toolkit plugin

Most users should just install the umbrella package — pip install hlido (plus hlido[crewai|langchain|nemo]) — one name for the whole Hlido Python surface. hlido-trust is the underlying core that the umbrella depends on.

NVIDIA NeMo Agent Toolkit

pip install "hlido[nemo]" registers the hlido function group via the nat.plugins entry point. In a workflow config:

function_groups:
  hlido:
    _type: hlido    # exposes hlido__trust_check, hlido__find_trusted,
                    # hlido__verify_claim, hlido__get_scorecard

No API key — Hlido's trust surface is public.

30-second use — a plain guard clause (no framework)

from hlido_trust import HlidoClient

hlido = HlidoClient()
if not hlido.trust_gate("aider", min_score=70):
    raise RuntimeError("Aider failed the Hlido trust gate — not delegating.")

trust_gate fails closed: an agent with no Hlido review, or one carrying a red flag, returns False.

CrewAI

from crewai import Agent
from hlido_trust.crewai_tool import hlido_crewai_tools

router = Agent(
    role="Delegation Router",
    goal="Only delegate to agents that pass an independent Hlido trust check.",
    tools=hlido_crewai_tools(),     # Hlido Trust Check + Hlido Recommend
)

LangChain

from hlido_trust.langchain_tool import hlido_langchain_tools

tools = hlido_langchain_tools()     # hlido_trust_check + hlido_recommend
llm_with_tools = llm.bind_tools(tools)

See examples/ for full "vet before you delegate" agents.

API

recommend returns the single top match on the free tier. Set HLIDO_API_KEY (a hlk_live_* key from https://hlido.eu/api/) to unlock k > 1.

HlidoClient(api_key="hlk_live_...")   # or export HLIDO_API_KEY

TrustVerdict fields

slug, name, score, tier (VITAL ≥90 / STEADY ≥70 / FADING ≥40 / FLATLINE), confidence, best_for, not_recommended_for, what_it_fails_at, red_flags, evidence_url, stale, found. Helpers: .recommended(min_score) and .summary().

Why

One agent that checks trust before delegating beats a thousand passive listings. Embedding Hlido as a callable step is how independent agent reviews actually get used — by humans and by agents.
