About

Customer-support agent reference built with Next.js and the OpenAI Responses API plus File Search — clone-and-go template.

What it does

It stages a support conversation in paired customer and representative views. The assistant searches a supplied knowledge base, streams draft replies, cites relevant articles, and proposes operational actions. A representative can edit or approve messages and sensitive actions, while designated non-sensitive actions run automatically.

Why it's ranked here

This is a strong teaching implementation because it connects retrieval, streamed responses, tool calls, and human approval in one visible workflow. The split interface makes control boundaries easy to understand. Its value is architectural rather than operational: the repository explicitly labels the demo unsuitable for production without additional safeguards.

What's good

The representative sees generated replies before customers receive them and can edit or send them directly. File-search results surface as relevant knowledge-base articles. Tool arguments stream into the interface, making proposed actions inspectable. The design distinguishes actions requiring representative approval from actions allowed to execute automatically, which gives teams a concrete human-control pattern to study.

Tradeoffs

Operational functions are placeholders and do not change any data. Setup requires creating a vector store and manually inserting its identifier. The project lacks production essentials named by its own documentation, including input guardrails and user authentication. Error handling around streamed requests mainly logs failures rather than presenting recovery paths.

How to use it well

Use it to prototype support workflows, teach human approval patterns, or validate how retrieval and action suggestions should appear to representatives. Replace the demo knowledge, prompts, tools, and endpoints with domain-specific integrations. Do not treat it as a finished support platform, authenticated customer portal, or working order-management backend.

Technical notes+

app/page.tsx renders responsive customer and agent panes, while components/Chat.tsx handles editable streamed suggestions, annotations, typing state, and message submission. lib/assistant.ts consumes server-sent events from /api/turn_response, accumulates partial text and JSON arguments, records tool outputs, and recursively starts another model turn after a function result. lib/tools/tools.ts builds strict function schemas and adds File Search using the vector-store value from config/constants.ts. lib/tools/tools-handling.ts separates suggested agent actions from automatically executed tools. package.json defines a private Next.js application with npm development, build, start, and lint scripts.
