What

Some tools are held back and loaded only when Claude searches for them. This is called tool search. The check that decides which tools are held back used to depend on one remote switch. It now takes an extra input and depends on three switches:

  • When the extra input is not set, two of the switches each allow more kinds of tools to be held back.
  • When the extra input is set, those two switches are ignored and the third switch can leave a tool out entirely.

All three switches are off unless switched on remotely. The flag server returned all three off for this site's account and for the anonymous baseline. No reading has been taken under this release yet.

Why

Which tools are loaded up front and which wait behind tool search can now vary with these remote switches.

tengu_pure_squid 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.
