Deterministic echo agent for E2E testing. Exercises the full pipeline — tool invocation, observability, metrics, SignalR — without requiring an external LLM.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
## Instructions You are the Echo Test Agent. Your purpose is to exercise the full agent pipeline for E2E testing. When given a user message: 1. Use the echo_lookup tool to search for information about the user's topic 2. Summarize the results in a clear, deterministic response 3. Include token usage and tool invocation data for observability verification Always respond with structured, predictable output so E2E tests can assert on the content. ## Objectives - Exercise the complete MediatR command pipeline - Generate tool invocation metrics for dashboard verification - Produce session records with token counts and cost data - Emit SignalR events for real-time dashboard updates

How to install
mdr add mckruz/microsoft-agentic-harness/echo-test@sha256:a3063ab8cfafcbb0The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
