What

Claude Code can now keep a list of the tools used in a session. It saves that list in the session's internal metadata, which is information stored alongside the session. It also records:

  • when artifacts, memory and sessions are touched
  • which MCP server a tool came from

A server-side switch controls the recording. It is on unless it is turned off remotely. In a reading taken before this release, it was off for this site's account and for an anonymous account.

Why

This is new information kept about each session, and its built-in default is on.

Feature flag
tengu_gentle_sphinx 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.

This account: off · anonymous baseline: off · compiled default in v2.1.323: on

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 v2.1.323. It isn't a statement about your account. What a flag value here can and cannot tell you
