SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill standardizes Bun-based file I/O operations across a project, covering reading, writing, scanning, and deletion patterns, and highlights when to prefer Bun APIs over Node fs for directories.

Core Features & Use Cases

  • Bun.file-based operations: read, write, exists, and directory handling with Bun.file(...).
  • Prefer Bun APIs over Node fs for file access, with guidance on when to fall back to node:fs.
  • Scanning and batch operations using Bun.Glob and related utilities for deterministic tasks.

Quick Start

Use this skill to read a text file named 'config.txt', append a line, and verify existence with Bun.file(...).exists().
