DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Permissions Notable not in their notes

Remote permission approvals can name the tool they applied to, off in interactive sessions.

nameToolOnPermissionAllow is on for headless cloud clients, defaulted off elsewhere by tengu_violin_wood.

Feature flag
tengu_violin_wood 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.

nameToolOnPermissionAllow
What

A new remote session option, nameToolOnPermissionAllow, makes an allow answer sent over the remote control channel include the name of the tool it applied to. The headless cloud client turns it on unconditionally; interactive remote sessions default it from tengu_violin_wood, which compiles in as false, so it is off there unless enabled server-side.

Details
  • The option is new in this build.
  • Interactive sessions share the same default predicate used for keeping undelivered responses.
