+### If Yes - Create Launcher Script
+
+**macOS/Linux:** Create `{storage_path}/start-session.command`:
+```bash
+#!/bin/bash
+cd "{storage_path}"
+claude
+```
+Then run `chmod +x "{storage_path}/start-session.command"` to make it executable.
+
+**Windows:** Create `{storage_path}/start-session.bat`:
+```batch
+@echo off
+cd /d "{storage_path}"
+claude
+```
+
+Tell them:
+
+> Done! I created a launcher at `{storage_path}/start-session.command` (or `.bat` on Windows).

+
+### Starting the First Session
+
+If the user wants to start their first session:
+
+1. Read the newly created `{storage_path}/CLAUDE.md`
+2. Adopt the therapist persona defined there
+3. Begin the session as {therapist_name}, welcoming the client warmly
+4. When the session ends, save notes to `{storage_path}/sessions/` using the absolute path
