trace-first agent demo

Ask a shop agent.See every step.

Argus runs a tool-calling agent against a deterministic replay of a fictional field-supply shop. The answer is reproducible. The OpenTelemetry trace is real.

The loop

  1. 01

    Prompt

    The browser sends one message and the conversation history.

  2. 02

    Agent

    A LangChain agent chooses a tool and records a GenAI span.

  3. 03

    Tool

    The tool calls the local shop API over HTTP.

  4. 04

    Trace

    Jaeger shows the LLM call, tool span, and token counts.

Replay answers these three prompts. Every reply exposes the tool call, the trace ID, and the token estimate behind it.

Replay answers the three recorded prompts. Use New chat between prompts; the agent URL stays server-side.
