Rubric Studio Open is a local-first IDE for authoring, validating, previewing, calibrating, diffing, and exporting criterion-level AI evaluation rubrics.

The app is intentionally single-user and file-based. A rubric is a folder on disk, so it can be reviewed in Git, shipped in CI, and exported into downstream evaluation runners without a hosted account.

Launch QA assets: authoring, preview scoring, calibration, diff, export, and short workflow video.

Production captures from https://rubric-studio.auraone.ai: authoring, preview, calibration, diff, export, and settings.

Production docs and website captures: docs home and AuraOne product page.

• Browser editor: Vite/React surface with browser constraints available through ?surface=browser.
• VS Code surface: extension scaffold under vscode-extension/ with a webview editor command, live rubric TOML diagnostics, completions, and quick fixes.

The example project in examples/helpful-response-evaluation/ shows the v0 folder layout:

rubric.toml
themes/*.md
criteria/<theme>/*.toml
samples/*.jsonl
judges/*.toml
exports/
.rubric/

The TypeScript domain model and Rust validator both enforce the same core contract: stable criterion IDs, required labels/descriptions, bounded weights, example guidance, explicit evidence requirements, and deterministic scoring fixtures.

Rubric Studio Open does not include hosted queues, payments, reviewer workforce management, multi-tenant RBAC, adjudication operations, or Cloud approval chains. The only commercial handoff is the explicit export flow labelled "Send to AuraOne for expert review"; it packages an intake artifact only after user confirmation.
