be/core.js — a tiny wrapper that re-exports the current bundled Be from index.js.
be/api.js — convenience helpers that attach showMenu to a Be instance and jibo.
be/skill-loader.js — a small helper scaffold for the skill discovery logic (extract from constructor later).
be/init.js — helper to attach hex-hitarea and menuManager and API after initialization.

Why this approach

The project currently ships a single large UMD bundle at index.js. Rewriting the bundle in-place is risky and unnecessary to get incremental improvements. The wrapper modules provide:

a stable, easy-to-edit place to move code into as you split responsibilities;
small, testable files to gradually extract logic from the big bundle;
backward compatibility: the bundle remains the authoritative runtime implementation.

How to continue

Move pieces of logic out of index.js into be/ files one-by-one.
Replace the corresponding logic in the bundle with small calls into the new modules.
When the split is complete you can replace the bundle with the new source and remove the generated file.

Example usage

After jibo.init() completes, call:

// from a skill's code (after Be is initted)
be.menuManager.showMenu('menu/menus/example-menu.json');

// or
be.showMenu('menu/menus/example-menu.json');

Notes

I kept changes minimal so runtime behavior is unchanged. If you want, I can now start moving specific functions (analytics init, skill loading, lifecycle methods) into these files and patch the bundle to call them. Tell me which section to extract first and I'll implement the extraction and tests.
