What is sanity-best-practices?

A collection of development guidance for Sanity, a content platform, covering schemas, queries, images, rich text, localization, migrations, and framework integrations.

Use it when setting up Sanity, designing schemas, writing GROQ queries, adding visual editing, configuring Studio, generating types, or connecting frameworks such as Next.js and Astro.

It helps developers follow consistent patterns when building or maintaining Sanity projects and reduces mistakes in content modeling and integrations.

About the project

Sanity Copilot eve Template is a Slack-based assistant that lets team members query and edit Sanity content, inspect schemas, manage drafts and releases, and send long-form drafts to Notion. Teams use it to work on Sanity projects through Slack with each person's permissions and approval controls for sensitive actions. The catalogue add-ons support this agent workflow.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00153	$0.00937
Opus 5	$0.00077	$0.00468
Sonnet 5	$0.00031	$0.00187
Haiku 4.5	$0.00015	$0.00094

Security

Grade A, and why

sanity-best-practices scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

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
Managing infrastructure with Blueprints
Automating content workflows with Sanity Functions

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.
Model relationships with reference fields, then resolve related documents with GROQ lookups, source-key fields, or returned _id values from created documents.
Use explicit document IDs mainly for singleton documents controlled by Studio Structure, including localized singletons such as homePage-en.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
