Workbook 1: a working artifact, not prose about one
how-toAn artifact is the finished thing in the side panel — and it isn't done until create, edit, and delete actually recalculate the totals.
The build: a personal finance tracker with daily/weekly/monthly views, category bar charts, full CRUD and a running balance — from one detailed prompt. The hard prerequisite is the settings checkpoint: Artifacts, AI-powered artifacts, and inline visualizations enabled (the AI-powered toggle is what lets the optional Fridge Chef call Claude from inside the artifact).
The workbook's quality bar is behavioral, not visual: 'the artifact is not complete if it only looks like a tracker.' Its troubleshooting table teaches the general repair grammar — name the failed action and ask the model to trace its state update; supply three known entries and ask it to show the calculation before touching code; ask to revert to the last working version when a refinement breaks things.
The Fridge Chef extension: type ingredients, press a button, and Claude — inside the artifact — suggests a dish with steps and a 'Surprise me' variant. The demonstration that artifacts can carry live AI behavior, not just UI.
GotchasNo artifact appears → restate 'as an interactive artifact, not a written plan.' Wrong totals → give three known entries and demand the calculation before code changes. Broken refinement → revert to last working version.
The fastest possible first win in AI building: a real interactive product in 15–30 minutes, plus the test-before-trust habit installed from day one.
If Claude rendered it, it works.
Rendering proves layout. The CRUD-and-totals test proves the product — the gap between the two is the whole lesson.
An Artifact is the finished thing in a side panel, not prose describing the thing.
Go deeper
In one line: Artifact = interactive finished output in the side panel (apps, dashboards, documents, diagrams, games). Build: finance tracker with 3 time views, category chart, CRUD + running balance; completion is measured by correct recalculation, not appearance. Fictional data only while learning.
Answer from memory first — the recall attempt is what makes it stick. Then reveal.
What's the workbook's completion test, and why isn't a screenshot enough?
Create, edit and delete must correctly update the totals — a tracker-looking layout with dead buttons fails. Behavior is the product.
