What problem does it solve? Developers working with the Bun runtime often struggle to remember correct CLI flag placement, watch versus hot reload behavior, bunfig.toml options, and module resolution rules, leading to misconfigured scripts and confusing import errors. ## Core Features & Use Cases - CLI Flag Guidance: Covers watch mode, hot reloading, debugging flags, preload scripts, env file loading, and workspace filtering with correct flag positioning. - bunfig.toml Configuration: Documents runtime, test runner, package manager, registry, and lockfile settings with complete examples. - Module Resolution Reference: Explains extension resolution order, ESM/CommonJS interop, package exports conditions, path aliases, and import.meta properties. - Use Case: When a developer sees "Cannot find module" after adding a path alias, the Skill directs them to the module resolution reference to fix tsconfig paths or package.json imports. ## Quick Start Ask how to run a TypeScript file with watch mode in Bun and get the correct command with flags in the right position.
