GraphQL

What This Skill Does

The GraphQL skill empowers your AI agent to act as a proficient API architect, handling everything from schema design to sophisticated performance optimization. It enables the agent to draft type-safe schemas, implement resolvers, configure DataLoader for N+1 problem mitigation, and design secure, production-ready GraphQL endpoints. The agent understands the nuances of Relay-style pagination, custom scalar validation, and the complexities of error handling within the GraphQL specification.

Installation

You can integrate this skill into your agent's environment by executing the following command in your terminal: clawhub install openclaw/skills/skills/ivangdavila/graphql

Use Cases

• API Prototyping: Rapidly scaffold schemas and input types for new features based on business requirements.
• Performance Tuning: Audit existing resolvers and implement caching or batching strategies to fix N+1 performance bottlenecks.
• Security Hardening: Design and configure query complexity analysis and depth limiting to prevent resource exhaustion attacks.
• Client Integration: Define robust query fragments and mutations that ensure seamless state management for frontend applications.

Example Prompts

1. "Generate a GraphQL schema for a multi-tenant blog platform, ensuring that authors can only fetch their own posts using an input filter, and include proper pagination using edges and pageInfo."
2. "Review the following resolver code and identify why it triggers an N+1 query problem, then refactor it using DataLoader to batch database requests effectively."
3. "Help me define a custom error handler in my Express GraphQL server that maps database constraint violations to specific user-facing error codes and paths."

Tips & Limitations

• N+1 Vigilance: Always implement DataLoaders for relations. Without them, even simple queries can cause exponential database load.
• Security First: Never expose your full schema in production without protection. Always use query complexity analysis to set a maximum cost for incoming requests.
• Mutation Strategy: Ensure your mutations return the modified object. This is a best practice that allows frontend caches (like Apollo Client) to automatically update the UI without needing an extra network request.
• Nullable Defaults: Be intentional with your type definitions. By default, fields are nullable in GraphQL. Explicitly mark critical fields as non-nullable using the '!' syntax to prevent silent runtime errors.
