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.

Claude Code v2.1.224

Tool schemas moved onto shared constructors

Under the hood
Useful1 Signal1
Build

Dozens of tool schemas were rewritten onto shared helpers purely to shrink the bundle.

What

Dozens of tool input and output schemas were rewritten to use short shared schema helpers. Descriptions and validation look unchanged; this is a size and consistency refactor.

Evidence

project_search: knowledge-base query

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

Related

Other releases about the same thing. Found by shared names or similar wording; neither means one caused the other.
