Develop, test, and publish Tampermonkey/Greasemonkey userscripts — scaffolding, in-browser validation via Claude in Chrome, README generation, and version bumping.
npx claudepluginhub danielrosehill/claude-code-plugins --plugin userscript-developmentBump a userscript's `@version` (semver), update README, commit, tag, and push. Tampermonkey only auto-updates installed scripts when `@version` increases — forgetting this means users never receive fixes.
Look up Tampermonkey documentation — metadata keys (`@match`, `@grant`, `@run-at`, etc.), the GM_* / GM.* API, and configuration. Fetches the official docs page on demand to stay current.
Generate or refresh a userscript repo's README.md from its `==UserScript==` metadata block — install button, what it does, supported sites, version, license. Idempotent; safe to re-run after metadata changes.
Set up a brand-new development workspace for a single userscript. Asks public or private, creates the GitHub repo with the chosen visibility, installs this plugin at project scope inside it, and ends. The user opens that repo in a fresh Claude Code session and starts authoring the script with `new-userscript`.
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.
First-run setup for userscript-development. Optionally records the user's userscript repos base directory so other skills can default new userscripts there. Skipping is fine — the plugin works without it.
Publish a userscript to GitHub so it can be installed via Tampermonkey's "Install from URL" using the raw GitHub URL. Wires up `@updateURL` and `@downloadURL` in the metadata block, commits, and pushes.
Validate a userscript end-to-end in a real Chrome tab via the Claude in Chrome MCP. Loads the target page, simulates the script's effect, reads console logs and DOM state, and reports whether the script's behavior matches its `@description`.
Develop, test, and publish Tampermonkey (and Greasemonkey-compatible) userscripts from inside Claude Code — scaffolding, in-browser validation via Claude in Chrome, README generation, semver-aware version bumping.
onboard — optional one-time setup. Records the user's userscript repos base directory so other skills can default new scripts there.new-userscript-repo — bootstrap a new per-script workspace: ask public/private, create the GitHub repo, install this plugin at project scope, end task.new-userscript — scaffold a new .user.js with a complete ==UserScript== metadata block.test-userscript — validate behavior live in a real Chrome tab via the Claude in Chrome MCP.publish-userscript — push to GitHub and wire @updateURL / @downloadURL so Tampermonkey can install from the raw URL.generate-readme — build a clean repo README from the metadata block.bump-version — increment @version (Tampermonkey only auto-updates on monotonic version increase), commit, tag, push.docs-lookup — fetch the official Tampermonkey docs on demand.The user can declare where they keep their userscript repos:
USERSCRIPT_REPOS_BASE=/path/to/userscripts (takes precedence)userscripts_base_path written by onboard to
${CLAUDE_USER_DATA:-${XDG_DATA_HOME:-$HOME/.local/share}/claude-plugins}/userscript-development/config.jsonSkipping is fine — skills will ask for a path each time if neither is set.
