1Mastering TypescriptMastering TypeScript is an agent skill package aimed at solo and indie builders who want production-grade TypeScript habits—not just syntax—wired into their repo. It treats type safety and lint discipline as part of the build loop: you get an ESLint 9 flat-config template built on @eslint/js and typescript-eslint, with strict and stylistic type-checked rule sets and parser options tuned for modern project references. The skill guides agents to enforce type-only imports, catch unhandled promises, forbid awaiting non-promises, and prefer nullish coalescing and optional chaining so refactors stay safe as the codebase grows. Use it when starting a TypeScript app, tightening an existing tsconfig, or before merge when types have drifted. It complements generic chat advice by anchoring decisions to checkable rules agents can apply file-by-file. It is not a substitute for tests or security review, but it reduces an entire class of TS foot-guns that slow shipping for one-person teams.553installs
