Misleading error message suggests non-existent /model command

Checks

• I have searched github.com/aws/amazon-q-developer-cli/issues and there are no duplicates of my issue
• I have run q doctor in the affected terminal session
• I have run q restart and replicated the issue again

Operating system

macOS 15.5.0 (24F74)

Expected behaviour

Error message should provide valid troubleshooting steps or commands that actually exist in the CLI.

Actual behaviour

When the model is temporarily unavailable, Amazon Q CLI shows an error message suggesting to use '/model' to select a different model, but this command doesn't exist and causes user confusion.

[chat-transcript]
I see you're trying to use a `/model` command, but this doesn't appear to be a valid command for Amazon Q CLI.

Here are the available commands and options for Amazon Q:

**Main commands:**
- `q c

> fix /model eevertime I am getting this errors

I understand you're getting errors with `/model` every time you try to use it. However, `/model` is not a valid command in Amazon Q CLI chat sessions.

To help you fix this issue, I need to understand what you're trying to accomplish. Are you:

1. **Trying to switch between different AI models?** - This isn't available as a chat command in Amazon Q CLI
2. **Getting this error in a different application?** - Please specify which application or tool you're using
3. **Expecting this to work based on other AI chat interfaces?** - Amazon Q CLI has its own specific command set

**Valid commands in Amazon Q CLI chat:**
- `/quit` - Exit the chat
- Regular questions and requests (no slash commands needed)

**To get help with Amazon Q CLI:**
\```bash
q --help
\```

Could you share:
- The exact error message you're seeing?
- What you expected `/model` to do?
- Whether this is happening in Amazon Q CLI or another tool?

This will help me provide the right solution for your specific situation.

I see the issue now! You're getting an error message that suggests using `/model` to select a different model, but this appears to be a bug in the Amazon Q CLI error message itself.

The `/model` command doesn't actually exist in Amazon Q CLI, which is why you're having trouble with it. This looks like an internal error where the model I'm running on is temporarily unavailable.

Here are some steps to resolve this:

## Immediate Solutions:

1. **Restart the chat session:**
   \```bash
   /quit
   \```
   Then start a new session:
   \```bash
   q chat
   \```

2. **Check your AWS configuration:**
   \```bash
   aws configure list
   q --help
   \```

3. **Try with a different AWS region (if applicable):**
   \```bash
   export AWS_DEFAULT_REGION=us-east-1
   q chat
   \```

## If the problem persists:

1. **Update Amazon Q CLI:**
   \```bash
   # If installed via npm
   npm update -g @aws/amazon-q-developer-cli
   
   # Or check for updates through your package manager
   \```

2. **Check service status:**
   The error suggests a temporary model unavailability, which could be a service-side issue.

## Report the Bug:

This error message is misleading since `/model` isn't a valid command. Would you like me to help you report this issue to the Amazon Q team?

Beginne bei crates/chat-cli/src/cli/chat/mod.rs:723 und prüfe, wo der Text des Fehlers „Modell nicht verfügbar“ zusammengesetzt wird. Vergleiche den vorgeschlagenen /model-Befehl mit den gültigen Amazon Q CLI-Chat-Befehlen, die im Issue beschrieben sind. Erledigt ist die Aufgabe, wenn der Fehler die Benutzer nicht mehr zu einem nicht vorhandenen Befehl weiterleitet und gültige Hinweise zur Fehlerbehebung bereitstellt.
