What

Claude can now automatically learn and remember patterns across sessions, writing insights to a persistent memory directory.

Activation: Auto-memory has a three-layer activation cascade (checked in order):

  1. Environment variable (highest priority): CLAUDE_CODE_DISABLE_AUTO_MEMORY=true forces off, =false forces on
  2. User setting: autoMemoryEnabled in ~/.claude/settings.json (per-project, overrides the feature flag)
  3. GrowthBook feature flag tengu_oboe (default fallback): server-side rollout control, defaults to false

If the flag is off for your account and you haven't set the user setting, auto-memory is disabled by default. Remote sessions (CLAUDE_CODE_REMOTE=true) also disable it unless CLAUDE_CODE_REMOTE_MEMORY_DIR is set.

How to enable: The toggle is in the /memory panel (not /settings). Type /memory to see "Auto-memory (research preview): off" at the top, then confirm to toggle it on. This writes autoMemoryEnabled: true to settings, overriding the feature flag. After enabling, "Open auto-memory folder" and per-agent memory entries also appear in the /memory panel.

Note: The feature flag tengu_oboe existed in v2.1.37 but with no user-facing toggle — auto-memory was purely server-gated. v2.1.38 added the autoMemoryEnabled setting, the /memory panel toggle, and the bidirectional env var override, making it opt-in for everyone.

Details
  • Per-project setting: autoMemoryEnabled controls whether Claude reads/writes to auto-memory
  • Memory guidance updated from "write down key learnings as you complete tasks" to "save patterns worth preserving across sessions"
  • New guidelines for what to save:
  • Stable patterns and conventions confirmed across multiple interactions
  • User preferences for workflow, tools, and communication style
  • Key architectural decisions and important file paths
  • Solutions to recurring problems and debugging insights
  • What NOT to save:
  • Session-specific context (current task details, in-progress work)
  • Speculative conclusions from reading a single file
  • Information that duplicates CLAUDE.md instructions
  • Supports explicit user requests: "always use bun", "never auto-commit", or "forget X"
Evidence

Activation logic (search for tengu_oboe), settings schema (search for "Enable auto-memory for this project"), /memory panel toggle (search for "Auto-memory (research preview):")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
