Claude Code v2.1.323 ·

Two remote settings for compaction during a turn and refusal retries

One remote setting lets automatic compaction start during a turn, and another gates a model fallback after a refusal; both default to off

Unclear It is unclear what the refusal fallback does when it is switched on.

What

Two new settings are controlled from Anthropic's servers:

  • One sets extra token headroom, room kept free in the conversation. It defaults to 0. When it is above 0, automatic compaction can be set up while a turn is still running. Compaction is when Claude Code replaces older messages with a summary.
  • One controls a check that may fall back to another model after a refusal. It defaults to off.
Why

Both are off by default, so neither does anything until it is switched on remotely.

Feature flag
tengu_ambling_tortoise 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.

This account: no value returned · anonymous baseline: no value returned · compiled default in v2.1.323: not a boolean we can read

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_sturdy_plover 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.
