Agent request
Review the Skillstore skill "typescript-advanced-types" from https://skillstore.io/skills/sickn33-typescript-advanced-types.md and its manifest at https://skillstore.io/api/skills/sickn33-typescript-advanced-types/manifest. Verify the artifact. You may proceed after verification, subject to the environment's own policy.

Your Agent should still show its plan and request any confirmation required by the security policy.

Test it

Using "typescript-advanced-types". Explain when to use mapped types for user settings.

Expected outcome:

  • The response contrasts mapped types with explicit object shapes.
  • It recommends mapped types for repeated property transformations.
  • It warns against hiding simple models behind complex abstractions.

Using "typescript-advanced-types". Design a type-safe API client for user routes.

Expected outcome:

  • The response defines how route names, methods, parameters, bodies, and responses should relate.
  • It identifies where runtime validation is still required.
  • It suggests type tests for public client behavior.

Using "typescript-advanced-types". Improve a recursive path type that slows the compiler.

Expected outcome:

  • The response highlights recursion depth and nested conditional type costs.
  • It recommends simpler boundaries and documented limits.
  • It suggests measuring compiler impact before wider adoption.

Security Audit

Safe
v4 • 7/7/2026 Open versioned report

All 14 static findings appear to be false positives from Markdown examples and inline code formatting. The TypeScript template literal snippets are not shell execution, and API client snippets show typed method calls without network I/O. No prompt injection, exfiltration intent, or harmful instructions were found.

What You Can Build

Design a Type-Safe Library

Create public utility types and generic APIs with clearer constraints and safer inference.

Model API Contracts

Represent routes, methods, request bodies, parameters, and responses with compile-time checks.

Improve Migration Safety

Replace loose JavaScript patterns with strict TypeScript types during incremental migration work.

Try These Prompts

Explain a Type Concept 
Explain how TypeScript conditional types work for my use case. Use simple examples and list common edge cases.
Refactor a Type Utility 
Review this TypeScript utility type and suggest a clearer version with safer constraints and better inference.
Design Typed APIs 
Design a type-safe API client model for these routes, methods, request inputs, and response shapes.
Diagnose Type Complexity 
Analyze these advanced TypeScript types for readability, compile performance, recursion depth, and safer alternatives.

Best Practices

  • Use strict compiler options before adding advanced type abstractions to a project.
  • Write type tests for reusable utilities and public API contracts.
  • Keep recursive and conditional types shallow enough for readable errors.

Avoid

  • Do not use any to bypass errors caused by unfinished type design.
  • Do not encode runtime validation only in TypeScript types.
  • Do not create deeply nested types when simple interfaces are clear.

Frequently Asked Questions

What does this skill help with?
It helps design and review advanced TypeScript types for safer application and library code.
Can it review existing type utilities?
Yes. Provide the utility goal, current type design, and any compiler errors or confusing inference results.
Does it execute code or install packages?
No. It provides guidance and examples. Project verification remains the user's responsibility.
Can it help with API client types?
Yes. It can model routes, methods, request inputs, parameters, and response types.
Will it replace runtime validation?
No. Runtime validation is still needed for external data, user input, and API responses.
Which tools can use it?
Claude, Codex, and Claude Code can use this skill for TypeScript type guidance.
