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.

Empty slot added to the Bash tool description

Under the hood
Useful1 Signal0
Elsewhere

The Bash tool description gained an empty slot for text that gets filled in later.

Both Bash description builders append an extra section whose supplier returns nothing in this build.

What

Both builders of the Bash tool's description now append an extra optional section, but the helper that supplies it returns nothing in this build, so the prompt is unchanged. It is a placeholder for a description block added later.

Evidence

Executes a given bash command and returns its output.

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