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.

egrep and fgrep Support in Bash Tool

The Bash tool's safe-command validation now recognizes egrep and fgrep as valid commands, applying the same safe flags as grep.

Evidence

egrep/fgrep support (search for "egrep" and "fgrep" in command safety checks)

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