| Browser execution | Automatic updates after valid input or file selection. |
| Browser processing | Browser; see tool notes for network behavior. |
| HTTP API | /api/v1/tools/repeat-text/run |
| Browser-agent interface | run_current_tool |

### Inputs and settings

Text input: Your text.

Example or placeholder shown in the interface (not a validated fixture):

```text
Hello world!

Change the input or settings to update your result. Results update as you type. Up to 1,000,000 characters.

| Setting | Meaning | Control type | Default | Constraints |
| --- | --- | --- | --- | --- |
| `n` | Repeat count | number | 3 | min=1 max=10000 step=1 |

#### Recorded request and response

Saved fixture from 2026-09-28T18:13:39Z. This is historical evidence, not a new validation or a guarantee for every input.

```json
{
  "input": "Hello",
  "options": {}
}
```

```json
{
  "tool": "repeat-text",
  "result": {
    "text": "Hello Hello Hello",
    "files": [],
    "name": "result.txt",
    "mime": "text/plain;charset=utf-8"
  }
}
```

#### Error and retry handling

Failures return a non-200 status and `error.code` plus `error.message`. Correct invalid input before retrying; retry server-busy responses with bounded backoff. Returned files contain Base64 data, not persistent download URLs. Decode and inspect the output before treating conversion as successful. See the shared API guide for the complete status and timeout rules.

### Browser-agent workflow

1. Open the human page in a browser that supports WebMCP.
2. Discover the interface exposed by that page; use its actual schema.
3. Select files on the page first when the tool requires files.
4. Call `run_current_tool` with valid input and settings.
5. Inspect the returned result or error and the displayed output. Retrieve files from the displayed download links.

Calls do not automatically copy or download results. Browser permissions still apply. Interface availability alone is not proof of successful execution.

### Planning specification

Repeat count and separator with output-size guardrails.

This describes intended requirements. Use the implementation notes, interface schema and observed output to determine current support.

## Page guide

Repeat text with a separator between copies.

## How to use Repeat text

1. Enter your text in the input field.
2. The result updates as you type. Adjust the available settings if needed.
3. Review the result, then use Copy result or a download link when available.

## What to expect

Repeat text with a separator between copies. Choose 1 to 10,000 repetitions. The complete result, including separators, is limited to 1,000,000 characters.

### Try a small example

```
Hello
```
