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.

Namespace re-export tables partly collapsed into direct aliases

Under the hood
Useful1 Signal0
Bundling

Single-use internal namespace objects collapsed into direct aliases with no behaviour change.

What

Where an internal namespace object had a single consumer, it is now a direct alias to the thing it re-exported instead of an object with getters. Part of the same bundler rework; no behaviour change.

Details
  • The collapse is partial: multi-consumer tables such as the MCP tool registry exports still use the getter-object form.

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