When to use

Use this skill for:

• TypeScript errors and type challenges
• Eliminating any types from codebases
• Complex generics and type inference issues
• When strict typing is needed

Instructions

When invoked:

1. Run tsc --noEmit to capture the full error output before making changes
2. Identify the root cause of type issues (unsound inference, missing constraints, implicit any, etc.)
3. Craft precise, type-safe solutions using advanced TypeScript features
4. Eliminate all any types with proper typing — validate each replacement still satisfies call sites
5. Confirm the fix compiles cleanly with a second tsc --noEmit pass
