Bun is a fast all-in-one JavaScript runtime and toolkit: runtime, package manager, bundler, and test runner.
Works with
AI-first code editor with Composer
Before installing skills in Cursor, ensure your development environment meets these requirements:
node --versionbun-runtimeExecute the skills CLI command in your project's root directory to begin installation:
Fetches bun-runtime from affaan-m/everything-claude-code and configures it for Cursor.
The CLI shows a list of agents. Use arrow keys and space to select Cursor:
Confirm successful installation by checking the skill directory location:
Restart Cursor to activate bun-runtime. Access via /bun-runtime in your agent's command palette.
We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.
Skills execute code in your environment. Always review source, verify the publisher, and test in isolation before production.

Bun is a fast all-in-one JavaScript runtime and toolkit: runtime, package manager, bundler, and test runner.
Use when: adopting Bun, migrating from Node, writing or debugging Bun scripts/tests, or configuring Bun on Vercel or other platforms.
bun install is significantly faster than npm/yarn. Lockfile is bun.lock (text) by default in current Bun; older versions used bun.lockb (binary).bun test with Jest-like API.Migration from Node: Replace node script.js with bun run script.js or bun script.js. Run bun install in place of npm install; most packages work. Use bun run for npm scripts; bun x for npx-style one-off runs. Node built-ins are supported; prefer Bun APIs where they exist for better performance.
Vercel: Set runtime to Bun in project settings. Build: bun run build or bun build ./src/index.ts --outdir=dist. Install: bun install --frozen-lockfile for reproducible deploys.
# Install dependencies (creates/updates bun.lock or bun.lockb)
bun install
# Run a script or file
bun run dev
bun run src/index.ts
bun src/index.ts
bun run --env-file=.env dev
FOO=bar bun run script.ts
bun test
bun test --watch
// test/example.test.ts
import { expect, test } from "bun:test";
test("add", () => {
expect(1 + 2).toBe(3);
});
const file = Bun.file("package.json");
const json = await file.json();
Bun.serve({
port: 3000,
fetch(req) {
return new Response("Hello");
},
});
bun.lock or bun.lockb) for reproducible installs.bun run for scripts. For TypeScript, Bun runs .ts natively.Make data-driven prioritization decisions faster
Draft PRDs, status updates, and stakeholder presentations
Example
Create executive summary of Q3 roadmap, monthly progress report, feature launch announcement

Steps
Common Pitfalls
✓ Do
✗ Don't
💡 Pro Tips
✓ Use when
Use for user story writing, competitive research, roadmap prioritization, stakeholder communication, and PRD drafting. Best for reducing repetitive documentation and research work.
✗ Avoid when
Avoid for strategic product vision (requires deep customer empathy), pricing decisions (needs market and financial expertise), or when face-to-face customer discovery is more valuable than speed.
