CLAUDE_CODE_CLASSIFIER_SUMMARY
Updated by Alex Sorokoletov
CLAUDE_CODE_CLASSIFIER_SUMMARY is a Claude Code environment variable: Carries the output of a prompt classifier as a structured summary. Where CLAUDE_CODE_VERIFY_PROMPT triggers classification, this variable holds the result so downstream hooks and audit logs can read it without re-running the classifier. Added between v2.1.118 and v2.1.123 and still present in v2.1.294. It is not in the official reference.
