Optimizes code for the Bun runtime by prioritizing native APIs for shell execution, file I/O, and testing.
This skill equips Claude with specialized knowledge of the Bun runtime, enabling it to write high-performance TypeScript and JavaScript code. It focuses on replacing traditional Node.js modules with Bun's faster alternatives, such as using Bun.$ for shell commands, Bun.file for I/O operations, and bun:test for unit testing. By providing specific patterns for workspace management and binary compilation, this skill ensures that generated code is idiomatic, efficient, and fully leverages the Bun ecosystem.
