Production AI Support Agent

The SupportAgent is a working AI customer-support agent you can point at your own knowledge base today — not a chat wrapper, but a full production agent that answers from your docs, knows when to escalate, and pauses for a human before it does anything with money.

The flow

search KBanswer (grounded)escalate if unsureresolvepause for approval

Production-grade from the first run

Grounded answers

Answers from your knowledge base with a retrieval-grounding confidence score, not free-associated guesses.

Durable refund approval

The refund tool is gated by human-in-the-loop and executes exactly once — even across a crash.

PII redaction

Customer data never reaches the model or a stored trace in the clear.

Cost & latency tracing

Every ticket is a step tree you can inspect, with its cost and latency.

Seeded evals

So a prompt change can't quietly regress answer quality.

Shipped on all five SDKs

The same agent against one shared production layer — proof the seam holds across every orchestration model.

Try it, then point it at your docs

bash

agentfast new support --sdk langgraph
# drop your docs into kb/, then:
docker compose up      # playground on :3400, dashboard on :3401

Runs keyless out of the box

It runs on a deterministic demo model with no API key, so you can watch the full answer → escalate → pause → resume flow before wiring in a real model.

Other use cases: the research agent and coding agent. Or pick your SDK integration.

Stop rebuilding the plumbing.

agentFast is the production layer — memory, 50 tools, observability, evals, guardrails, human-in-the-loop — for LangGraph, CrewAI, the Claude & OpenAI Agent SDKs & Vanilla. Own it for life.
