Feature Request: Direct shell command execution syntax (e.g., !ls)

### Checks

- [x] I have searched [github.com/aws/amazon-q-developer-cli/issues](https://github.com/aws/amazon-q-developer-cli/issues?q=) and there are no duplicates of my issue
- [x] I have run `q doctor` in the affected terminal session
- [x] I have run `q restart` and replicated the issue again

### Operating system

Linux 6.14.0-29-generic - Ubuntu 24.04.3 LTS

### Expected behaviour

Users should be able to execute shell commands directly within the Q chat prompt using a special syntax like `!command`. For example:
- `!ls` to list directory contents
- `!pwd` to show current directory
- `!git status` to check git status
- `!cat filename.txt` to view file contents

This would provide immediate command execution without needing to ask the AI assistant to run the command via the execute_bash tool.

### Actual behaviour

Currently, there is no direct shell command syntax available in the Q chat interface. Users must ask the AI assistant to run commands, which then uses the execute_bash tool. This adds extra steps for simple, quick commands.

> is there a way i can run a local shell command inside the q prompt? Like, a ! syntax or something. for example, if i wanted to just check the content of the local directory, could i just do a !ls or something similar?

Based on the Q CLI documentation, there is **no direct shell command syntax like `!ls`** documented for running commands within the Q chat prompt.

However, you can run shell commands in two ways:

1. **Ask me to run commands** - You can simply ask me to run shell commands like "list the contents of the current directory" and I'll use the `execute_bash` tool to run `ls` for you.

2. **Use the `/editor` command** - The documentation mentions an `/editor` command that opens your `$EDITOR` (defaults to vi) to compose a prompt, but this is for composing chat messages, not executing shell commands.

The `execute_bash` tool is available and can run shell commands, but it requires going through the AI assistant rather than having direct shell access with a special syntax.

For your example of checking directory contents, you would just ask: "show me the contents of the current directory" and I would execute `ls` for you.

The documentation doesn't mention any special syntax like `!` for direct shell command execution within the chat interface.

> seems like that would be a good feature.

I agree! A direct shell command syntax like `!ls` would be a convenient feature for quick commands without having to ask the AI assistant each time.

If you'd like to suggest this as a feature request, you can use the `/issue` command to open a GitHub issue template. This will create a pre-filled issue on the Amazon Q CLI repository where you can describe the feature request for direct shell command execution syntax.

The development team would be able to see community interest in features like this through the GitHub issues.

### Steps to reproduce

1. Open Q chat interface
2. Try to run a shell command with `!ls` or similar syntax
3. Command is not recognized as a shell command
4. User must instead ask "please run ls" and wait for AI to execute via execute_bash tool
