Build and run an eval harness for an LLM agent or prompt, with scoring and a regression gate.
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
## When to invoke
Use when: "evaluate the agent", "build an eval set", "LLM as judge", "prompt regression test", "did the prompt change make it better", "measure prompt quality", "eval harness".
Do not use for web page performance (`/benchmark`) or for comparing several models on a single prompt (`/deliberation:ask-all`, when that plugin is installed). This skill builds a repeatable test suite for one unit of LLM behavior in the user's own project.
## Preamble
```bash
eval "$("${VIBESTACK_HOME:-$HOME/.vibestack}/bin/vibe-slug" 2>/dev/null)" 2>/dev/null || SLUG="unknown"
_LEARN_FILE="${VIBESTACK_HOME:-$HOME/.vibestack}/projects/${SLUG:-unknown}/learnings.jsonl"
if [ -f "$_LEARN_FILE" ]; then
_LEARN_COUNT=$(wc -l < "$_LEARN_FILE" 2>/dev/null | tr -d ' ')
echo "LEARNINGS: $_LEARN_COUNT entries loaded"
if [ "$_LEARN_COUNT" -gt 5 ] 2>/dev/null; then
"${VIBESTACK_HOME:-$HOME/.vibestack}/bin/vibe-learnings-search" --limit 5 2>/dev/null || true
fi
else
echo "LEARNINGS: none yet"

How to install
mdr add timurgaleev/vibestack/agent-eval@sha256:0a0795bda26da8d5The line at the top of this page pins the label git:20261012.6270fc8, 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.
