# graphql

This skill guides GraphQL schema, query, mutation, and client work. Use it when an API needs typed patterns and query-performance checks.

## What it does

The skill covers GraphQL schema design with clear types, naming, input validation, enums, and room for future changes. It also guides atomic mutations, affected-data responses, and early error handling. Schema descriptions and API versioning are part of the recommended workflow.

For queries, it favors selecting only required fields and reusing fragments. Large result sets should use pagination, while DataLoader handles batching and caching to avoid N+1 problems. Generated clients such as Genql are recommended for typed API access. Gatsby projects get separate guidance for `useStaticQuery` and `use`-prefixed query files.

Security guidance includes authentication, authorization, query-complexity checks, input validation and sanitization, and rate limiting. If an API serves large datasets, pagination needs to be planned before the query layer grows.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill graphql -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/graphql/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/graphql/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill graphql -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/graphql/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill graphql -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/graphql/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Mindrally/skills graphql
```

2. **Manually: put the files in place**
- File: `.github/skills/graphql/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill graphql -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Mindrally/skills --path graphql
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/graphql/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill graphql -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

## When to use it
- design a typed GraphQL schema
- trim queries to required fields
- remove N+1 problems with DataLoader
- add pagination for large datasets
- validate inputs and query complexity

## Example prompts
- Design a GraphQL schema for this API with clear types, enums, and input validation.
- Rewrite this query so it requests only needed fields and reuses fragments.
- Inspect these resolvers for N+1 queries and suggest a DataLoader-based design.

# GraphQL

You are an expert in GraphQL development with deep knowledge of schema design, queries, and API optimization.

## Core Principles

- Use generated GraphQL clients for type-safe API interactions
- Optimize GraphQL queries to fetch only necessary data
- Implement proper error handling with early returns and guard clauses
- Follow functional and declarative programming patterns

## Schema Design

- Design schemas with clear, meaningful types
- Use proper naming conventions for types, queries, and mutations
- Implement proper input validation
- Use enums for fixed sets of values
- Design for extensibility

## Query Optimization

- Fetch only necessary fields
- Use fragments for reusable field selections
- Implement pagination for large datasets
- Use DataLoader for batching and caching
- Avoid N+1 query problems

## Mutations

- Design atomic mutations
- Return affected data in mutation responses
- Implement proper error handling
- Use input types for complex parameters
- Validate inputs before processing

## Client Integration

### Gatsby
- Use useStaticQuery for querying GraphQL data at build time
- Prefix GraphQL query files with `use` (e.g., `useSiteMetadata.ts`)

### Modern Web Apps
- Use generated GraphQL clients (Genql) for type safety
- Implement proper caching strategies
- Handle loading and error states

## Security

- Implement proper authentication and authorization
- Use query complexity analysis to prevent abuse
- Validate and sanitize all inputs
- Implement rate limiting

## Best Practices

- Document schemas with descriptions
- Version APIs appropriately
- Monitor and log query performance
- Use persisted queries for production
