CLAUDE_CODE_ALDER_WICKET
A Claude Code environment variable, read out of the shipped bundle. It was in the build from v2.1.217 and was gone by v2.1.218.
Boolean. When true, the system prompt includes a # Delivering work section (Deliver what the user asked for, at the scope they intended.). The section is also included when the tengu_alder_wicket key in cached client data is true or the tengu_alder_wicket flag is on.
Not Anthropic's. Written by Claude Opus 5.5 from reading the v2.1.217 bundle, and it can be wrong.

Presence across releases
2Build by build
80One 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.
