Evaluation and Regression Tests for Hermes Workflows

Build an eval suite that catches model, prompt, tool, and workflow regressions before students ship agents.

What the local Hermes build teaches

This build lab focuses on the test suite that turns agent behavior from anecdote into evidence. The goal is not to copy a private machine setup. The goal is to learn the architecture pattern well enough to build a small, classroom-safe version.

Agent evals should include fixed prompts, expected tool calls, mocked APIs, scenario simulations, scoring rubrics, and regression thresholds.

Hermes pattern	Student build	Risk to handle
Name the boundary	a ten-case regression suite for one Hermes-style workflow	changing a prompt, model, or tool schema and trusting a single happy-path demo
Keep the interface small	Start with one happy path and one failure path	Avoid a demo that only works when everything is perfect
Make the system observable	Log decisions, status, and errors in plain language	Do not log private data or secrets

Build the small version

Draw or write a ten-case regression suite for one Hermes-style workflow.
Mark which parts are user-facing, which parts are internal, and which parts require approval.
Choose one low-risk workflow and implement only that workflow first.
Add one failure case before adding a second feature.
Write a short operator note: what the agent may do, what it must ask about, and what it must never do.

  rubric:
    - no hosted provider call
    - concise summary
    - no private name in logs
  pass_threshold: all_requiredA classroom-safe skeleton inspired by the local Hermes architecture scan.

The big idea: eval suite is not decoration. It is part of the product architecture students need before an agent becomes safe enough to use with real people.
