   Thanks for the detailed report. I traced the point where the chain breaks.

   TL;DR: This isn't a claudecode.nvim send-path bug. The plugin still sends your selection and current-file info correctly over the IDE WebSocket; the notifications are being dropped on the Claude Code CLI side while the agents view is focused.

   The plugin still sends

   <leader>as / :ClaudeCodeSend broadcasts an at_mentioned notification, and selection/file tracking broadcasts selection_changed (active file + selection). I verified both still go out by swapping the claude binary for a small fake IDE client that does the same discovery + WebSocket handshake the real CLI does and logs what it receives:

   RECV selection_changed  filePath=.../sample.lua  isEmpty=false  line=0..7
   RECV at_mentioned       filePath=.../sample.lua  lineStart=0 lineEnd=7
   

   Both arrive at the connected IDE client — so the producer side is fine.

   Where it breaks

   In the Claude Code CLI (checked 2.1.161), the at_mentioned handler is gated on the currently-focused IDE client:

   handler extracted from the CLI binary

   useEffect(() => {
     let O = xu(H);                  // IDE client for the focused context
     if (q.current !== O) q.current = O;
     if (O) O.client.setNotificationHandler(zF3(), (T) => {
       if (q.current !== O) return;  // <-- dropped when the focused context isn't this client
       // ... insert @mention into the prompt ...
     });
   });

   When the agents view is focused, the active context is re-scoped, so the notification arriving on the IDE connection hits a now-stale handler and is silently discarded. That also explains why the current-file info stops coming through. The plugin only has one connection and can't see or influence which agent Claude has focused, so there's no plugin-side fix.

   Workaround

   Disable the agents view (or switch back to the main chat view before sending). The CLI exposes a toggle:

   CLAUDE_CODE_DISABLE_AGENT_VIEW=1
   

   You can set it straight from the plugin config so it's always applied to the Claude terminal:

   require("claudecode").setup({
     env = { CLAUDE_CODE_DISABLE_AGENT_VIEW = "1" },
   })

   With the agents view off, send-to-CC works as before.

   I'd also suggest filing this upstream with Claude Code, as inbound IDE at_mentioned / selection_changed should apply to the IDE-connected session (or be forwarded to the focused agent) regardless of the agents’ view.
