An early control-plane comment read with token fallback sits behind tengu_onyx_sluice, off in this build.

What

The artifact comment reader gains an option to try the control plane first and fall back to the normal token-based read, scoring the attempt either way. The flag involved, tengu_onyx_sluice, falls back to off in this build.

Details
  • When the sandbox blocks outbound traffic to the content host, the read can now recover using an already-successful control-plane result instead of failing.
Evidence

tengu_onyx_sluice

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

Read from
Feature flag
tengu_onyx_sluice Off by default, switched on for this account

The shipped code defaults this off, and the flag server returned on for the one account this site reads on this version. That is the reading that makes the entry above worth a second look, and it still says nothing about your account.

This account: on · anonymous baseline: on · compiled default in v2.1.236: off

Read once, for one account on one subscription tier, against v2.1.236. 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 on for tengu_onyx_sluice, 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.
