new-userscript

name	new-userscript
description	Scaffold a new Tampermonkey userscript with a complete `==UserScript==` metadata block, sensible defaults, and a starter IIFE body. Drops it in the user's userscripts base directory if configured, otherwise asks where to place it.

New Userscript

Create a new userscript file ready to load into Tampermonkey.

Resolve the base path

Order of precedence:

1. $USERSCRIPT_REPOS_BASE env var
2. userscripts_base_path from ${CLAUDE_USER_DATA:-${XDG_DATA_HOME:-$HOME/.local/share}/claude-plugins}/userscript-development/config.json
3. Ask the user

Inputs

• Script name (kebab-case for filename, human-readable for @name)
• Target site(s) — for @match / @include (use @match by preference; it's stricter)
• What the script does — one sentence for @description
• Run timing — document-start | document-end | document-idle (default document-idle)
• Needed APIs — any GM_* / GM.* grants (default none)

Metadata block reference

Use the official Tampermonkey metadata keys. Common ones:

// ==UserScript==
// @name         <Human Name>
// @namespace    <stable URL or reverse-domain>
// @version      0.1.0
// @description  <one sentence>
// @author       <name>
// @match        https://example.com/*
// @icon         https://www.google.com/s2/favicons?sz=64&domain=example.com
// @grant        none
// @run-at       document-idle
// @license      MIT
// ==/UserScript==

Body template

(function () {
    'use strict';

    // TODO: implement
    console.log('[<script-name>] loaded on', location.href);
})();

Layout

Create <base>/<script-name>/:

• <script-name>.user.js — the script (Tampermonkey requires the .user.js suffix for install URLs)
• README.md — placeholder; tell the user to run generate-readme later
• .git — git init it so it's ready to publish

If the user prefers single-file userscripts (no per-script directory), accept <base>/<script-name>.user.js instead. Ask once and remember the choice in the user's config if they want.
