Glob
A Claude Code tool, read out of the shipped bundle. It was in the build from v2.1.138 and was gone by v2.1.162.
The built-in claude-api agent lost Read, Grep and Glob and now only has WebFetch scoped to one docs domain.
Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.259.

Presence across releases
3Build by build
265One row per release since the first build this name was read out of. Absent means the build was read and the name was not in it, never mined means no bundle for that release was ever archived, and a declared type or a default is only ever what that release's own bundle stated.
Read out of the published npm bundle release by release, and out of Anthropic's own documentation as this site captured it. Nothing on this page is a description anybody here wrote about what the tool does. All tools.
