From 93b340bdc4f9aad26446b4a1d2e368e4ddcc690d Mon Sep 17 00:00:00 2001 From: itsskofficial Date: Sat, 31 Oct 2026 09:49:07 +0530 Subject: [PATCH 1/4] fix(llm): keep Claude Code's account identity out of memory-off chats Claude Code adds context of its own next to Sentient's system prompt. Every run now turns off CLAUDE.md files, auto memory and the git snapshot with Claude Code's documented switches. The signed-in account's email can't be removed by any supported flag while Claude Code uses the plan login, so in a turn that may not use memory (incognito with memory off, an app's turn without memory) Claude is told those notes aren't the user's and the account email is replaced in the reply, its thinking and tool call arguments unless the turn itself contains it.
