CLAUDE_CODE_MEMORY_PUSH_DELETE_MODE

Updated October 13, 2026 by Alex Sorokoletov

CLAUDE_CODE_MEMORY_PUSH_DELETE_MODE is a Claude Code environment variable: Controls how deletions propagate when memory is pushed upstream — a delete-mode knob for the memory subsystem that gained account- and organization-scoped sync in v2.1.210 (CLAUDE_CODE_DISABLE_ORG_MEMORY, gate tengu_haze_glass). Added between v2.1.143 and v2.1.212 and still present in v2.1.294. It is not in the official reference.

How to set it

For one session, export it in the shell that starts Claude Code:

export CLAUDE_CODE_MEMORY_PUSH_DELETE_MODE=<value>
claude

To apply it to every session, add it to the env object of a settings file:

// ~/.claude/settings.json
{
  "env": {
    "CLAUDE_CODE_MEMORY_PUSH_DELETE_MODE": "<value>"
  }
}
