Is this skill safe for production environments?

Yes, it is designed with security in mind, using array arguments for shell commands to prevent injection attacks and including TOCTOU protection for file integrity.

Does it support both synchronous and asynchronous operations?

Yes, it provides both sync and async versions for most common functions including reading, writing, directory checks, and existence testing.

Can I use this for hashing files or data?

Absolutely. The skill includes built-in support for SHA256 for cryptographic needs and xxHash64 (via fastHash) for extremely fast non-cryptographic caching operations.

Why use bun-fs-helpers instead of node:fs?

These helpers leverage Bun's native performance, use less token overhead for AI interactions, and provide built-in safety against command injection compared to standard Node.js modules.

安全与测试

Provides secure, token-efficient, Bun-native filesystem operations for Claude Code workflows without node:fs dependencies.

This skill integrates high-performance, Bun-native filesystem utilities into Claude Code, replacing standard Node.js FS modules with faster, more secure alternatives. It leverages Bun's native APIs (Bun.file, Bun.write, and Bun.spawn) to provide command-injection safe operations, recursive directory management, and atomic file updates. Designed for developers who prioritize speed and security, it includes built-in TOCTOU protection and efficient hashing, making it an essential toolkit for automation scripts, data processing, and tool-building within the Bun runtime environment.
