[BUG] Claude Code in Desktop - No way to TURN OFF Prompt Suggestions

### Preflight Checklist

- [x] I have searched [existing issues](https://github.com/anthropics/claude-code/issues?q=is%3Aissue%20state%3Aopen%20label%3Abug) and this hasn't been reported yet
- [x] This is a single bug report (please file separate reports for different bugs)
- [x] I am using the latest version of Claude Code

### What's Wrong?

Every action I take in Claude Code now triggers a prompt suggestion in the input field, telling me what to type next. I don't want this. It distracts me from my line of thoughts.

What I've tried:

- No toggle exists in settings for this.
- Putting instructions in settings.json does nothing, it's ignored.
- Same with CLAUDE.md, ignored.
- Claude itself has no idea this is even happening when I ask it about it.

### What Should Happen?

There should be a toggle or config setting to disable this.

### Error Messages/Logs

```shell

```

### Steps to Reproduce

Only in Claude Desktop > Claude Code:

Submit a prompt.

The model answers

Hint prompt automatically appears.

### Claude Model

Not sure / Multiple models

### Is this a regression?

No, this never worked

### Last Working Version

It has always been like this

### Claude Code Version

2.1.215 (Claude Code)

### Platform

Anthropic API

### Operating System

Windows

### Terminal/Shell

PowerShell

### Additional Information

_No response_

Start by reproducing the behavior in Claude Desktop > Claude Code on Windows with Claude Code 2.1.215. Inspect how settings.json and CLAUDE.md are handled, then trace where the automatic hint prompt appears after a model response. Done means a user-facing toggle or configuration setting reliably prevents the suggestions from appearing.
