Master API Mocking with MSW 2 for AI Agents and LLMs
This software skill offers a comprehensive guide to mastering API mocking with MSW v2.15, specifically designed for AI agents and large language models (LLMs). It provides a structured framework consisting of 48 rules divided into 8 categories, helping developers effectively refactor and generate code using MSW.
What this skill does
- Guides the setup and initialization of MSW for testing or development environments.
- Provides instructions for writing and organizing request handlers to simulate REST or GraphQL APIs.
- Assists in configuring test environments and debugging handler matching issues.
- Facilitates the testing of error states and edge cases in applications relying on AI agents and LLMs.
- Supports the integration of MSW into existing testing frameworks.
Who it is for
- Software developers and engineers leveraging AI coding agents like Claude Code, Cursor, and Codex.
- Quality assurance professionals responsible for testing AI applications.
- Development teams focused on improving testing processes and application reliability.
Use cases
- Developers setting up MSW to simulate API responses during local development of AI-driven applications.
- Teams conducting end-to-end testing to validate the interaction between AI agents and backend services.
- Creating and refining request handlers to support scenario-based testing, ensuring robustness of applications.
Technical details
- Requires Node.js 18+ for optimal compatibility with MSW v2.
- Includes guidance on version control with worker scripts for consistent test environments.
- Supports TypeScript configuration to integrate seamless API mocking with existing projects.
- Comprehensive categorization includes setup, handler architecture, test integration, response patterns, request matching, GraphQL mocking, advanced patterns, and debugging & performance.

Here's what buyers say about the skills they use every day.
Ran it on a client's Google Ads account and it flagged wasted spend we'd been missing for months. Paid for itself on day one.
Optimize Ad Spend: Ad Account AuditorWe finally caught broken conversion tags before launch instead of after. The pre-launch checklist alone is worth the price.
Optimize Conversion Tracking: Pre-Launch QADropped it into Claude Code and my LCP went from 4.1s to 1.9s in an afternoon. It explains every fix it suggests, so I actually learned something too.
Optimize Core Web VitalsOur agency uses it as the final review step on every PR now. It catches security issues our linters never did.
Optimize Your Code: Best Practices & SecurityMade WCAG 2.2 compliance actually manageable. It walked through our whole storefront and produced a fix list our devs could work from directly.
Enhance Web Accessibility: WCAG 2.2As an expat freelancer in France, the DGFIP simulation saved me a very expensive appointment with an accountant. Incredibly thorough.
AI Tax Audit Skill: DGFIP Fiscal ControlWorks with both Cursor and Claude Code exactly as advertised. Setup took less than five minutes with the included README.
Optimize Profits: AI Conversion Value MapperInstant delivery, clean files, clear docs. This is how digital products should be sold. Already bought three more skills.
AI Comptable: French AccountingSupport answered my install question within a couple of hours on a Sunday. The skill itself has become part of my daily workflow.
