Unclear It is not known which files are affected.

What

You can mention a file in your prompt by typing @ and its name. Behind a remotely controlled switch, some of these mentioned files are no longer added to the list of files Claude is told you referred to.

The switch is off unless it is turned on remotely. The flag server returned it off for this site's account and for the anonymous baseline. No reading has been taken under this release yet.

Why

This may be a quiet trial of a change to how some @-mentioned files are passed to Claude. With the switch off, nothing changes.

Feature flag
tengu_twinkly_babbage 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.

Read once, for one account on one subscription tier, against v2.1.321. It isn't a statement about your account. What a flag value here can and cannot tell you

What has happened since
Flag reading moved The flag server now returns nothing at all, having stopped carrying it for tengu_twinkly_babbage, read as this account. A reading is one sample. Claude Code evaluates its flags remotely, so no client sees the targeting rule behind a value and this says nothing about your account.
