What
CLAUDE_CODE_TOTAL_TOKENS_REMINDER_BUDGET, which sets the token count at which Claude Code reminds itself about context usage, was being read through a stale variable on its final branch, so a value you set could be ignored. It is now checked correctly and falls back to the built-in default when unset or not positive.
Evidence
CLAUDE_CODE_TOTAL_TOKENS_REMINDER_BUDGET
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
