CLAUDE_BG_DISPATCHER_RATE_LIMIT_TIER

env in the build JSON

A Claude Code environment variable, read out of the shipped bundle. It has been in the build since v2.1.251, including the newest one read.

Two env vars let background dispatchers inherit your plan and rate tier without an API call.

Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.251.

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 environment variable does. All environment variables.
