agent-evals SKILL.md skillA

agent-evals from nahid-sparktales/agent-dispatcher is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Build an eval suite that can actually detect a regression — cases pulled from real traffic, graders that check properties rather than vibes, a recorded baseline, and per-case diffs in both directions. Use before claiming a prompt, model or agent change is an improvement, when agent behaviour must not regress, or when someone reports "it seems better" after eyeballing a handful of outputs. Not for tracing what one run did (llm-observability), not for testing deterministic code, and never as…

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

# Agent evals

"It seems better" is a sample of three, remembered favourably. An eval exists to turn a change in a
prompt, model, tool or retrieval step into a number you can defend — and to tell you honestly how
much of the system that number covers.

## When this fires

Before a prompt, model, tool definition or retrieval change is called an improvement; when agent
behaviour is depended on and must not silently regress; when a production failure needs to become
something that cannot come back. It does not fire for deterministic code paths, which are tests.

## Procedure

1. **Name the decision the eval serves** — "is this change an improvement", "can this ship", "which
   of these two prompts". A suite with no decision attached gets built once and read never. Write
   the decision above the suite.
2. **Take cases from real traffic, not imagination.** Pull them from logs, traces, support tickets
   and the failure that prompted this work. Invented cases test the behaviour you already thought
   of, which is the behaviour least likely to be broken. Freeze the set and version it with the
   code.

How to install

The exact contents, by fingerprint

mdr add nahid-sparktales/agent-dispatcher/agent-evals@sha256:009248110b5152fe

The line at the top of this page pins the label git:20260919.a0d4f55, 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.
