Leet Speak Skill

Overview

Pass any text string along with an encode or decode mode parameter. The engine replaces letters with numeric or symbolic equivalents when encoding, or restores standard Latin letters when decoding. Every response returns the converted text string, the applied mode, and the exact count of modified characters.

The tool

Once your client is connected to the VerveKit server, this appears in its tool list as LeetSpeakSkill. It is read-only and open-world — it fetches and never mutates anything on your side — so most clients call it without asking you to confirm.

{
  "name": "LeetSpeakSkill",
  "arguments": {
    "text": "hello world",
    "mode": "encode"
  }
}

You do not name the tool yourself; the model picks it. Asking about hello world in the terms this skill covers is enough for it to reach for LeetSpeakSkill on its own — naming it explicitly also works, and is the way to force the call.

Connecting

One server URL covers every skill in the catalog, including this one. Authorization is OAuth: the client opens a browser once, and there is no key to paste into a config file.

{
  "mcpServers": {
    "vervekit": {
      "url": "https://api.vervekit.com/v1/mcp"
    }
  }

Per-client setup — Claude, Cursor, VS Code, ChatGPT — is on the MCP setup page.

Arguments

These are the properties on the tool's inputSchema, so a well-behaved client validates them before the call is made. Premium arguments are accepted on every plan but only take effect on plans that include them.

What the model gets back

The result carries a structuredContent object matching the tool's declared outputSchema, so a client reads fields without parsing prose. status is "ok" and error is null on success; a null field means the value was not available for that input, not that the call failed.

{
  "status": "ok",
  "error": null,
  "data": {
    "text": "7h!5 !5 4 5!mp13 p!3c3 0f 73x7",
    "mode": "encode",
    "changedCharacters": 17
  }
}

Response fields

Paths are relative to data. Premium fields are absent rather than zeroed on plans that do not include them, so check for presence instead of comparing to 0.

Failure modes

Errors come back as tool errors carrying a sentence the model can act on, not a bare status code. Error handling covers the full list.

A call costs 2 credits each time the tool actually runs; a model that reasons about the tool without calling it costs nothing.

Use cases

Content Moderation

Detect banned keywords hidden in community forum posts by decoding obfuscated characters into standard text before running profanity checks.

Username Duplicate Prevention

To catch duplicate registrations trying to bypass unique name rules using number substitutions, identity services normalize gamer handles before saving.

Gaming Chat Filters

In-game chat systems convert incoming player messages back into standard vocabulary to flag abusive behavior across multiplayer lobbies.

Retro Profile Styling

When generating novelty badges or cyberpunk titles, social applications convert usernames and status messages into stylized character strings.
