# Claude Code v2.1.266: system prompt > 2 added and 8 removed, of 216 lines, about 71 words, in the prompt 17 of 27 arms receive. 3 other prompts also changed. 1 of 30 tool descriptions changed. The appended system-reminder blocks moved: 17 lines added. Compared against v2.1.265. The two arm counts on this page measure different things: 17 arms receive the prompt the headline is about, and the widest edit below reached 5, because the same changed lines sit in more than one prompt.
