Profile →npx skills add rohitg00/skillkit --skill good-skill --agent codex
Same command for any agent — swap --agent for claude-code, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# TypeScript Best Practices ## When to Use Use this skill when: - Writing new TypeScript code - Reviewing TypeScript pull requests - Refactoring JavaScript to TypeScript ## Triggers Activated when editing `.ts` or `.tsx` files in the project. ## Rules ### Always - Always use `const` for variables that won't be reassigned - Always use explicit return types on exported functions - Always prefer `interface` over `type` for object shapes ### Never - Never use `any` — use `unknown` instead - Never use `var` — use `const` or `let` - Never ignore TypeScript errors with `@ts-ignore` ## Examples ```typescript // Good: explicit return type export function calculateTotal(items: Item[]): number { return items.reduce((sum, item) => sum + item.price, 0); } ``` ```typescript // Good: discriminated union type Result<T> = | { success: true; data: T } | { success: false; error: Error }; ``` ## Boundaries - Do not modify `tsconfig.json` without explicit permission - Do not add new dependencies without checking existing utilities - Focus only on TypeScript patterns, not runtime behavior

How do I install it?
Run `npx skills add rohitg00/skillkit --skill good-skill --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From rohitg00/skillkit, a repository with 1,422 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
