Bun Project Skill

Instruction priority

Follow explicit user constraints and higher-priority system/developer instructions over this skill. When the user narrows scope, forbids external tools, asks for chat-only output, or gives a conflicting workflow, adapt accordingly and briefly note any meaningful deviation.

Goal

Help agents make Bun-aware technical decisions in any Bun project. This skill is about Bun itself: core features, APIs, practical gotchas, and official docs.

Bun is one executable (bun) that combines runtime, package manager, script runner, test runner, bundler, HTTP server runtime, and tooling/CLI foundation.

Core mental model:

Bun = Web-standard APIs + Bun-native APIs + Node/npm compatibility
