What this skill does
Practical Async Patterns with fp-ts Stop writing nested try/catch blocks. Stop losing error context. Start building clean async pipelines that handle errors properly. TaskEither is simply an async operation that tracks success or failure. That's it. No fancy terminology needed. Detailed Guide Read the detailed guide before executing this skill. It retains the complete procedure and reference material. Treat its safety, prerequisites, and validation requirements as mandatory. For focused work, load the relevant sections; for end-to-end work, read the guide completely. When to Use You need async error handling in TypeScript with TaskEither. The task involves wrapping Promises, composing API calls, or replacing nested try/catch flows. You want practical fp-ts async patterns instead of academic explanations. --- 5. Real API Examples Complete Fetch Wrapper Database Operations (Prisma Example) File Operations (Node.js) --- Limitations Use this skill only when the task clearly matches the scope described above. Do not treat the output as a substitute for environment-specific validation, testing, or expert review. Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
