 ### Claude Code Hook Setup
 
+#### Option A: Automatic via `/update-config` skill
+
+If you use [Claude Code](https://claude.ai/code), you can set up the hook automatically. Type this in Claude Code:

+- **buffer**: Full path to the current buffer's file, or buffer name for non-file buffers (e.g. `*Messages*`). Selections work in all buffers — select the relevant text to include it in context.
