name	deno
description	Deno runtime, TypeScript-native development, permissions, and built-in tooling. Use when working with deno, deno.json, deno serve, deno test, deno fmt, or building TypeScript projects with the Deno runtime.

Deno

• Use deno fmt for formatting - no prettier config needed.
• Use deno lint for linting.
• deno test for testing - built-in test runner.
• Permissions are explicit: --allow-read, --allow-write, --allow-net, --allow-env.
• Prefer URL imports over npm packages when possible.
• Use deno.json or deno.jsonc for project configuration.
• Standard library at https://deno.land/std/ - prefer stdlib over third-party.
• TypeScript is native - no tsconfig.json needed unless customizing.
