# lsp-server-name-too-short

## Rule Details

This rule checks the top-level keys in `lsp.json`, which serve as server names, and warns when any name is shorter than the configured minimum length. Descriptive names like `typescript-server` or `python-lsp` make configurations easier to maintain and debug.

### Incorrect

Server name that is too short

```json
{
  "t": {
    "command": "/usr/bin/tsserver"
  }
}
```

### Correct

Descriptive server name

```json
{
  "typescript-server": {
    "command": "/usr/bin/tsserver"
  }
}
```

## How To Fix

Rename the server key to a more descriptive name that identifies the language or purpose, such as `typescript-server`, `python-lsp`, or `rust-analyzer`.

## Options

Default options:

```json
{
  "minLength": 2
}
```

Require server names of at least 3 characters:

```json
{
  "minLength": 3
}
```

## When Not To Use It

Disable this rule if you have an established convention using short abbreviations for server names that are well-understood by your team.
