## Tool capabilities

| Property | Value |
| --- | --- |
| Tool ID | `dot-case` |
| Category | text-tools |
| Implementation | Registered implementation. Registration alone is not a production-quality guarantee. |
| Browser execution | Automatic updates after valid input or file selection. |
| Browser processing | Browser; see tool notes for network behavior. |
| HTTP API | /api/v1/tools/dot-case/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.

No additional settings are declared for this tool.

### HTTP contract

API calls process supplied data on the server. The website origin is `https://happytails.ai`. Server API hosting is not connected on the public website yet. Use your local server origin to test these requests.

```http
POST https://happytails.ai/api/v1/tools/dot-case/run
Content-Type: application/json
```

#### Recorded request and response

Saved fixture from 2026-09-28T18:13:46Z. This is historical evidence, not a new validation or a guarantee for every input.

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

```json
{
  "tool": "dot-case",
  "result": {
    "text": "hello.world",
    "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

Dot-separated identifiers with explicit handling of existing punctuation.

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

## Page guide

Join lowercase words.with.dots.

## How to use Dot case

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

Join lowercase words.with.dots. Spaces and punctuation become word boundaries. The result is useful for naming conventions but is not a validated domain name, file path or software identifier.

### Try a small example

```
Hello world
```
