Supercharge Your Sanity CMS Development with Claude Code Plugins

Transform Your Sanity Development Workflow with AI-Powered Precision

Building a robust content management system with Sanity CMS demands expertise across multiple domains: schema design, query optimization, migration strategies, and custom plugin development. What if you could accelerate every aspect of this workflow while maintaining production-quality code standards?

Enter Sanity Agents - a comprehensive Claude Code plugin marketplace specifically designed for Sanity CMS developers. This suite of seven specialized plugins transforms how you build, optimize, and maintain Sanity-powered applications, delivering measurable performance improvements: 87% faster queries, 93% smaller payloads, and zero-downtime migrations.

Whether you're architecting complex content models, optimizing GROQ queries, or building custom Studio plugins, Sanity Agents provides the AI-powered assistance that turns hours of development into minutes of guided execution.

What Are Sanity Agents and Why Do They Matter?

Sanity Agents represents a new paradigm in headless CMS development - a collection of intelligent, context-aware Claude Code plugins that understand the intricacies of Sanity's architecture. Unlike generic AI coding assistants, these plugins are built with deep knowledge of Sanity's schema language, GROQ query syntax, migration patterns, and Studio customization APIs.

The Three-Tier Architecture

Sanity Agents employs a sophisticated three-tier architecture that adapts to your workflow:

1. Commands (Interactive)

Interactive workflows that guide you through complex tasks with prompts and questions. Perfect for initial setup and configuration tasks where you need to make informed decisions.

2. Agents (Autonomous)

Self-directed AI assistants that analyze your codebase, identify optimization opportunities, and execute multi-step solutions. These agents work independently to solve complex problems like query optimization or migration planning.

3. Skills (Auto-Triggered)

Context-aware capabilities that activate automatically when Claude Code detects specific patterns or file types. Skills provide just-in-time assistance without requiring explicit invocation.

This architecture ensures you get the right level of assistance at the right time, from guided setup to autonomous optimization.

The 7 Core Plugins: Your Sanity Development Arsenal

1. Schema Helper - Intelligent Content Modeling

The Schema Helper plugin transforms content modeling from a manual, error-prone process into a guided, best-practice-driven workflow.

Key Capabilities:

• Interactive schema generation with validation rules
• Automatic field type recommendations based on content patterns
• Reference relationship mapping and circular dependency detection
• TypeScript type generation aligned with your schema definitions

Practical Example:

1
// Before: Manual schema definition with potential issues
2
export default {
3
  name: 'blogPost',
4
  type: 'document',
5
  fields: [
6
    {
7
      name: 'author',
8
      type: 'reference',
9
      to: [{type: 'author'}]
10
      // Missing validation, preview config, etc.
11
    }
12
  ]
13
}
14
 
15
// After: Schema Helper generates production-ready schemas
16
export default defineType({
17
  name: 'blogPost',
18
  type: 'document',
19
  fields: [
20
    {
21
      name: 'author',
22
      type: 'reference',
23
      to: [{type: 'author'}],
24
      validation: (Rule) => Rule.required(),
25
      options: {
26
        filter: 'status == "active"',
27
        disableNew: true
28
      }
29
    }
30
  ],
31
  preview: {
32
    select: {
33
      title: 'title',
34
      author: 'author.name',
35
      media: 'mainImage'
36
    },
37
    prepare({title, author, media}) {
38
      return {
39
        title,
40
        subtitle: `by ${author}`,
41
        media
42
      }
43
    }
44
  }
45
})

Impact: Reduces schema development time by 60% while ensuring consistency across your content model.

2. GROQ Assistant - Query Optimization Powerhouse

GROQ (Graph-Relational Object Queries) is powerful but complex. The GROQ Assistant plugin makes query optimization accessible and measurable.

Key Capabilities:

• Query performance analysis with bottleneck identification
• Automatic projection optimization to reduce payload size
• Join and reference pattern recommendations
• Query complexity scoring and alternative suggestions

Optimization Example:

1
// Before: Unoptimized query fetching unnecessary data
2
*[_type == "post"] {
3
  _id,
4
  _createdAt,
5
  title,
6
  slug,
7
  author->,
8
  categories[]->,
9
  "comments": *[_type == "comment" && references(^._id)]
10
}
11
 
12
// After: GROQ Assistant optimized query
13
*[_type == "post"] | order(publishedAt desc) [0...10] {
14
  _id,
15
  title,
16
  "slug": slug.current,
17
  "authorName": author->name,
18
  "categoryNames": categories[]->title,
19
  "commentCount": count(*[_type == "comment" && references(^._id)])
20
}

Results:

• 87% faster query execution
• 93% smaller response payloads
• Reduced API costs through efficient data fetching

3. Migration Helper - Zero-Downtime Content Transformations

Content migrations are notoriously risky. The Migration Helper plugin brings safety and confidence to schema evolution.

Key Capabilities:

• Automated migration script generation
• Dry-run simulation with impact analysis
• Rollback plan generation
• Batch processing with progress tracking
• Data validation before and after migration

Migration Workflow:

1
// Migration Helper generates comprehensive migration scripts
2
import {defineMigration} from 'sanity/migrate'
3
 
4
export default defineMigration({
5
  title: 'Migrate author field to authors array',
6
  documentTypes: ['post'],
7
 
8
  // Safety checks
9
  filter: '_type == "post" && defined(author)',
10
 
11
  migrate: {
12
    document(doc, context) {
13
      return {
14
        ...doc,
15
        authors: [doc.author],
16
        author: undefined
17
      }
18
    }
19
  },
20
 
21
  // Validation
22
  onComplete: async (context) => {
23
    const orphanedPosts = await context.client.fetch(
24
      '*[_type == "post" && !defined(authors)]'
25
    )
26
    if (orphanedPosts.length > 0) {
27
      throw new Error(`${orphanedPosts.length} posts missing authors`)
28
    }
29
  }
30
})

Safety Features:

• Automatic backup recommendations

      ...S.documentTypeListItems().filter(
35
        (listItem) => !['settings', 'post'].includes(listItem.getId())
36
      )
37
    ])

Technical Advantages: Why Sanity Agents Outperforms Manual Development

TypeScript-First Architecture

Every plugin generates fully-typed TypeScript code with comprehensive IntelliSense support. This eliminates runtime errors and provides exceptional developer experience.

Type Safety Example:

1
// Generated schemas include full type definitions
2
import {defineType, defineField} from 'sanity'
3
import type {SanityDocument} from '@sanity/types'
4
 
5
export interface BlogPost extends SanityDocument {
6
  _type: 'blogPost'
7
  title: string
8
  slug: {current: string}
9
  author: Reference<Author>
10
  publishedAt?: string
11
  body: PortableTextBlock[]
12
}
13
 
14
export const blogPostSchema = defineType<BlogPost>({
15
  name: 'blogPost',
16
  type: 'document',
17
  // Full type safety throughout
18
})

Production-Ready Code Generation

Unlike generic code generators, Sanity Agents produces code that adheres to Sanity's official best practices and includes:

• Comprehensive error handling
• Loading and empty states
• Accessibility attributes (ARIA labels, keyboard navigation)
• Performance optimizations (memoization, lazy loading)
• Security best practices (input sanitization, CSP compliance)

Performance Optimization Focus

Every plugin prioritizes performance:

• GROQ Assistant: Identifies N+1 query problems and suggests batching
• Migration Helper: Implements batch processing to prevent memory issues
• Widget Creator: Generates memoized components with optimized re-renders
• Schema Helper: Recommends indexing strategies for large datasets

Extensibility and Customization

All generated code is fully customizable and well-documented. Plugins create starting points, not black boxes - you maintain complete control over the final implementation.
