Our review
This skill fixes TypeScript errors by identifying root causes, applying minimal corrections, and verifying compilation succeeds.
Strengths
- Automated error detection via the TypeScript compiler
- Encourages precise fixes and avoids workarounds like `any`
- Iterative verification process until zero errors
- Guides toward specific types and typed assertions
Limitations
- Depends on TypeScript configuration; errors may be hidden if config is too lenient
- Cannot automatically fix complex structural mismatches; requires human understanding
- Does not cover runtime errors that static typing does not catch
When you need to resolve TypeScript compilation errors in an existing codebase.
When the issue is a logic bug rather than a type error, or when you need to design new complex types from scratch.
Security analysis
SafeThe skill uses only safe commands: 'npx tsc --noEmit' for type checking, along with Read and Edit tools. There is no destructive or exfiltrating behavior, no network requests beyond npm if tsc is not installed, and no execution of arbitrary code.
No concerns found
Examples
Run `npx tsc --noEmit` to check for TypeScript errors, then fix each error one by one with minimal changes. Continue until no errors remain.Fix the TypeScript errors in the file src/services/user.ts. Use proper type annotations instead of `any` or `@ts-ignore`.name: fix-types description: Fix TypeScript errors user-invocable: true allowed-tools: Bash(npx tsc *), Read, Edit

Check for Errors
npx tsc --noEmit
Instructions
Review the TypeScript errors above and fix each one:
- Identify the root cause - Understand why the type error is occurring
- Fix with minimal changes - Don't over-engineer; make the smallest change that correctly resolves the issue
- Verify the fix compiles - After fixing, re-run the type check
Guidelines
- Prefer fixing the actual type issue over using
anyor@ts-ignore - If a type assertion is needed, use
aswith a specific type rather thanas any - Consider whether the error reveals a real bug vs. a type definition gap
- Update interfaces/types if the shape has legitimately changed
Verification
After fixing all errors, run the type check again to confirm:
npx tsc --noEmit
Continue until there are no type errors remaining.
