typescript-pro
Implements advanced TypeScript type systems, creates custom type guards, utility types, and branded types, and configures tRPC for end-to-end type safety. Use when building TypeScript applications requiring advanced generics, conditional or mapped types, discriminated unions, monorepo setup, or full-stack type safety with tRPC.
Install
With your agent
Install OMGSkills skill "jeffallan/claude-skills:typescript-pro" into this agent's normal skills directory: call the OMGSkills MCP get_install_plan tool for your agent and run the script it returns (it installs only the pinned commit and verifies SKILL.md), and stop if MCP or the pin is unavailable. Do not overwrite or change existing skills without asking me.

TypeScript Pro Core Workflow Analyze type architecture - Review tsconfig, type coverage, build performance Design type-first APIs - Create branded types, generics, utility types Implement with type safety - Write type guards, discriminated unions, conditional types; run tsc --noEmit to catch type errors before proceeding Optimize build - Configure project references, incremental compilation, tree shaking; re-run tsc --noEmit to confirm zero errors after changes Test types - Confirm type coverage with a tool like type-coverage; validate that all public APIs have explicit return types; iterate on steps 3–4 until all checks pass Reference Guide Load detailed guidance based on context: | Topic | Reference | Load When | |-------|-----------|-----------| | Advanced Types | references/advanced-types.md | Generics, conditional types, mapped types, template literals | | Type Guards | references/type-guards.md | Type narrowing, discriminated unions, assertion functions | | Utility Types |...
