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

# Sanity Best Practices

Comprehensive best practices and integration guides for Sanity development, maintained by Sanity. Use the quick reference below to load only the one or two topic files that match the task.

## When to Apply

Reference these guidelines when:
- Setting up a new Sanity project or onboarding
- Integrating Sanity with a frontend framework (Next.js, Nuxt, Astro, Remix, SvelteKit, Hydrogen)
- Writing GROQ queries or optimizing performance
- Designing content schemas
- Implementing Visual Editing and live preview
- Working with images, Portable Text, or page builders
- Configuring Sanity Studio structure
- Setting up TypeGen for type safety
- Implementing localization
- Migrating content from other systems
- Building custom apps with the Sanity App SDK
- Developing or deploying a Studio or app in the Sanity Dashboard
- Managing infrastructure with Blueprints
- Automating content workflows with Sanity Functions or webhooks

## Global Rules

- Let Sanity generate `_id` values for ordinary documents. Do not create deterministic UUIDs, slug-derived IDs, or legacy-system IDs when creating documents.

How to install

The exact contents, by fingerprint
mdr add sanity-io/agent-toolkit/sanity-best-practices@sha256:f756ca3feaf736f2

The line at the top of this page pins the label git:20261009.3fe6c8a, 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.
