Chrome tool instructions can be moved to the end of Claude's instructions

A remote setting can move the Chrome tool's instructions note to the end, and a remote switch now controls one deferred tool

What

Three remote switches, which Claude Code's servers can set, are involved:

  • tengu_moonlit_goblet: a setting whose chromeNoteLast option moves the note about the Chrome tools to the end of the instruction updates Claude receives.
  • tengu_merry_tide: decides whether one deferred tool, a tool loaded only when needed, is available. It falls back to off when the server sends nothing.
  • tengu_rippling_map: still controls the extra mark on HTTP MCP tool calls and still falls back to on.
Why

The Chrome change tests whether putting that note last helps caching, where the model reuses earlier parts of the instructions instead of reading them again.

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.
