Source Intelligence

DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

The same wrapper removal, seen in the spinner word list

Under the hood
Useful1 Signal0
Bundling

The same load-time change is visible in the spinner word list; behaviour is unchanged.

What

The bundler's lazy per-module wrappers are gone, so module-scope side effects run at load rather than on first use. The spinner verb list, for example, sat inside a closure in the previous build and is a bare top-level array here. Timing changes, behaviour does not.

Details
  • Not gated; this is the shape of the build itself.
  • Also fixes the order in which module-scope state is created, since it no longer depends on who imports what first.
Evidence

"Zigzagging"

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
