A new `CLAUDE_CODE_AUTO_COMPACT_WINDOW` environment variable also allows users to override the auto-compaction window size.\n\n**Evidence**\n\nFeature-flag-controlled read limits (search for `\"tengu_amber_wren\"`, `\"CLAUDE_CODE_AUTO_COMPACT_WINDOW\"`)\n\n- Flag `tengu_amber_wren`: Not enough to say (read for one account on one subscription tier against v2.1.75; this account: no value returned, anonymous baseline: no value returned, compiled default: no gate table built for this version) 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."}
