IceyWu Utils

Use this skill when the task touches packages/utils source, public API surface, or dependency policy.

Preferences

• Keep @iceywu/utils at zero runtime dependencies. If you think a third-party helper is needed, first try to inline a minimal port (see lodash-lite/ for pattern).
• Prefer pure functions over stateful helpers; when state is intrinsic (e.g. debounce), expose control handles (clear, flush, trigger, isPending).
• Keep the root entry (src/index.ts) intentionally small. Large domains go behind explicit subpaths.
• Treat exported types as part of the product surface — breaking type shapes requires a changeset.
