Understanding complex TypeScript error messages and their underlying causes can be challenging, hindering effective debugging and resolution. This Skill provides a detailed diagnostic report to clarify type issues.

Core Features & Use Cases

Run Type Check: Executes type checking for a target file and collects all errors.
Classify Errors: Groups errors by category (e.g., type mismatches, missing properties, null safety) and severity.
Root Cause Analysis: Traces each error to its source, explaining why the error occurs and how it propagates.
Actionable Recommendations: Suggests specific, immediate fixes and identifies type refactoring opportunities for long-term improvements.
Use Case: Analyze the TypeScript errors in src/services/api.ts, providing a report with root causes, severity, affected code snippets, and recommended fixes for each issue, enabling quick and effective resolution.
