Claude Code v2.1.299 ·

A remote switch can now offer one tool in more cases

One tool can now be offered when an extra condition holds and a remote switch is on, and the shared tool description needs that same condition

Unclear Which tool this is, and what the extra condition checks, is not identified.

What

Two remote switches, both off unless they are switched on remotely, now control a tool:

  • Availability: one tool used to be offered only when a single check passed. It is now also offered when a further condition holds and the first remote switch is on.
  • Shared description: the shared tool description, which was already behind its own remote switch, now also needs that same further condition before it is used.
Why

This widens the cases where a tool that is held back by default is offered to Claude. It also narrows when the shared description appears.

Feature flag
tengu_merry_tide 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 v2.1.299: off

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.

tengu_peaceful_leaf 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.

What has happened since
Flag reading moved The flag server now returns off for tengu_merry_tide, 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.
