Unclear It is not stated what either switch controls.
What
Deferred tools are tools that are not declared to Claude in full from the start. This release adds settings that change how they are announced:
tengu_snug_nautilusis a remote setting read as an object, falling back to nothing (null). SettingwhenToUse: truein it, with an optionaldeferlist of strings, turns on the behaviour. Nothing has been read about this setting.tengu_modular_marbleis a separate switch. It falls back to false and is true only when the server value is exactly true. The flag server returned off for this site's account and for the anonymous baseline; no reading has been taken under this release.- This path no longer reads
tengu_composed_treehouse. Before, it checked that switch or the session'stellsDeniescondition.
Why
If the server turns it on, Claude's list of deferred tools can carry descriptions of when each tool is worth using, which can change which tools Claude reaches for. Without a server value, nothing changes.
tengu_snug_nautilus Not enough to sayNothing 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 v2.1.323: not a boolean we can read
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
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.
