Use case · Feature testing

A new AI workflow ships. Test it before launch.

A new agentic workflow has no track record. Ask your coding agent to scaffold checks and scenarios for it so you can see how it behaves before release — knowing that scaffolded checks arrive provisional, for you to review.

Build checks for this new AI workflow before we release it.
You Build checks for this new AI workflow before we release it.
Your coding agent · Claude Code plugin Scaffolded a starter set for the new workflow: metrics for task completion, tool use, and a rubric for tone. They land proposed · informational — they report, they don’t gate, until you review them. I authored the scenarios from your spec; I did not generate reference data. Verdict informational, as it should be before launch.

What it checks

new metrics and rubrics for the workflow · scenarios you author from the spec. Scaffolded checks land proposed · informational — they don’t gate until you review them. Automated scenario generation is a decided non-goal non-goal — no generator ships, by design; you author scenarios from your spec. A “launch scorecard” is evidence, never approval-to-launch.

Discover what to measure next

Before you can test a new workflow, you need the right checks. The discovering-metrics skill deep-reads your repo, prompts, output shapes, and exported traces to propose a typed MetricCatalog — anchored to the ways your app actually fails, across an eleven-dimension quality taxonomy and three tiers (deterministic, reference, judge) — and scaffolds it into the canonical evals/ layout. Everything it proposes lands proposed / uncalibrated and informational: it suggests what to measure, it never approves it. This is what to measure, not scenario generation.

The scorecard

feature checks · new workflow informational
Task completion0.83 proposed
Tool use0.90 proposed
Tone (rubric)uncalibrated

Verdict informational — every check is proposed and ungated. Illustrative example, not a measured result.

What it will not claim

A launch scorecard is not a launch approval. Scaffolded checks are proposed until you validate them, scenario generation is a decided non-goal — no generator ships, by design — and EvalGlass authors cases from your spec, it does not manufacture reference data. No false green →
