DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Feature flag
tengu_onyx_plover Not enough to say

Nothing here resolved what this flag was doing on this version, so nothing here should be read as on or off.

This account: no value returned · anonymous baseline: no value returned · compiled default in v2.1.94: no gate table built for this version

These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.

Read once, for one account on one subscription tier, against v2.1.94. It isn't a statement about your account. What a flag value here can and cannot tell you

What

New "Dream" system that automatically prunes and consolidates memory files in the background between sessions.

Details
  • Two dream modes:
  • Pruning: "delete stale or invalidated memories, and collapse duplicates"
  • Consolidation: "synthesize what you've learned recently into durable, well-organized memories"
  • User setting: autoDreamEnabled (boolean) — "Enable background memory consolidation (auto-dream). When set, overrides the server-side default."
  • Default thresholds: minimum 24 hours and 5 sessions between dreams (configurable via server flag)
  • Memory files are treated as immutable — combining means deleting old files and writing fresh single-fact replacements
  • Tool constraints during dream: Bash restricted to read-only commands plus rm for .md files inside the memory directory
  • Existing autoDreamEnabled setting existed in v2.1.92 but the Dream prompts and pruning/consolidation logic are new
Evidence

Dream instructions (search for "Dream: Memory Pruning", "autoDreamEnabled", "tengu_onyx_plover")

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