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.

Compact recall/remember summaries in the transcript

Memory

Memory recall notes could show as a compact grouped line in normal sessions, but that view is off.

A compact 'Recalling/Recalled' memory view exists behind tengu_stone_shell and falls back to off.

Feature flag
tengu_stone_shell Off in both readings

The flag server returned off for the account this site reads and for the anonymous baseline. A reading of off cannot rule out a rollout these two readings sit outside of.

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.

What

Memory attachments rendered only in verbose or transcript mode; a compact fallback view exists for normal sessions but is switched off in this build.

Details
  • When the gate is on, non-verbose sessions get a compact grouped node built from the attachment's memories
  • Labelled "Recalling"/"Recalled" or "Remembering"/"Remembered" depending on whether the group is still active
  • Gated on tengu_stone_shell, fallback false

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