Fix TypeScript Errors Automatically

The problem

TypeScript compiler errors can block builds and stall CI/CD pipelines. Manually tracing obscure generic mismatches and strict mode violations across large monorepos is time-consuming and prone to lazy 'any' casts.

What it does

• Analyzes TypeScript compiler output to trace errors back to root cause files and definitions.
• Applies surgical type fixes to interfaces, props, and generics without altering runtime logic.
• Validates fixes by running project-specific typecheck or build commands.
• Prioritizes type narrowing and proper guards over unsafe type assertions.
• Provides a structured report of modified files and validation results.

Frameworks & tools

TypeScript, React, Next.js, Node.js, npm, yarn, pnpm.

Why this beats prompting it yourself

Standard LLM prompts often suggest 'any' or @ts-ignore to silence errors. This skill is hard-coded to prefer type safety and minimal changes, ensuring your codebase doesn't lose its integrity just to pass a build.

Use cases

• Resolving complex React prop type mismatches after a library update.
• Fixing broken builds caused by TypeScript strict mode migrations.
• Refactoring interfaces and types across multiple files to satisfy the compiler.
• Debugging generic type errors in shared utility functions.
