+## Auto-Save Plugin Issues
+
+Using auto-save plugins can cause diff windows opened by Claude to immediately accept without waiting for input. You can avoid this using a custom condition:

+
+```lua
+opts = {
+  -- ... other options
+  condition = function(buf)
+    local fn = vim.fn
+    local utils = require("auto-save.utils.data")
+
+    -- First check the default conditions
+    if not (fn.getbufvar(buf, "&modifiable") == 1 and utils.not_in(fn.getbufvar(buf, "&filetype"), {})) then
+      return false
+    end
+
+    -- Exclude claudecode diff buffers by buffer name patterns
+    local bufname = vim.api.nvim_buf_get_name(buf)
+    if bufname:match("%(proposed%)") or
+       bufname:match("%(NEW FILE %- proposed%)") or
+       bufname:match("%(New%)") then
+      return false
+    end
+
+    -- Exclude by buffer variables (claudecode sets these)
+    if vim.b[buf].claudecode_diff_tab_name or
+       vim.b[buf].claudecode_diff_new_win or
+       vim.b[buf].claudecode_diff_target_win then
+      return false
+    end
+
+    -- Exclude by buffer type (claudecode diff buffers use "acwrite")
+    local buftype = fn.getbufvar(buf, "&buftype")
+    if buftype == "acwrite" then
+      return false
+    end
+
+    return true -- Safe to auto-save
+  end,

 ## Troubleshooting
 
 - **Claude not connecting?** Check `:ClaudeCodeStatus` and verify lock file exists in `~/.claude/ide/` (or `$CLAUDE_CONFIG_DIR/ide/` if `CLAUDE_CONFIG_DIR` is set)
