A Claude Code CLI flag, read out of the shipped bundle.
It has been in the build since v2.1.198, including the newest one read.
Option of claude plugin eval. Skips each case's scaffold_script, which is also the default when neither --scaffold nor --no-scaffold is passed; --scaffold turns it on and prints a note that the script runs as you.
Not Anthropic's. Written by Claude Opus 5.5 from reading the v2.1.286 bundle, and it can be wrong.

No release's published evidence quotes this name. The ledger indexes the Evidence lines of every changelog on this site, so this says nobody here has ever quoted it; it says nothing about how old the name is.

One 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 CLI flag does. All CLI flags.
