What it does
Add Editor Package is an agent skill from elementor/elementor. External: Add an Editor V2 package from a third-party plugin that injects UI or in-editor MCP tools. elementor/editor/v2/packages, init(), slots, adapters.
Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It works with npm and webpack. The repository describes itself as: The most advanced frontend drag & drop page builder. Create high-end, pixel perfect websites at record speeds. Any theme, any page, any design. The licence is GPL-3.0.
When your agent uses it
- Tasks that involve MCP servers
Example prompts
- “/add-editor-package”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- PHP: register package slug — append to elementor/editor/v2/packages (e.g. editor-my-feature). Optional env via…
- Build — webpack (or Vite) with @elementor/* as externals resolved at runtime via window.elementorV2.* — see packages/docs/architecture.md…
- Output contract — bundle exposes window.elementorV2.{camelCaseSlug} (e.g. editor-my-feature → editorMyFeature). Slug → global…
- Enqueue your bundle — wp_register_script() / wp_enqueue_script() with the plugin's own URL (e.g. plugins_url( 'assets/js/my-bundle.js'…
- src/init.ts(x) — synchronous registration only; re-export from src/index.ts.
What it can do on your machine
Read from SKILL.md and the folder at commit dd32c13. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are javascript and typescript).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Add Editor Package loads about 1.7k tokens when it runs. Until then it costs about 44 tokens; SKILL.md has 482 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Add editor package
Scope: External — the full documented outcome is shippable from a 3rd-party plugin via
elementor/editor/v2/packagesand your own packageinit(); no Core changes required. Editing core packages is Core-only. Full split + disclaimer: skills-scope.md.
Implementation location
- Editor JS/TS: third-party plugin repo — own package bundle with
init()(npm/webpack or hand-built script). - PHP: filter
elementor/editor/v2/packagesand optionalelementor/editor/v2/scripts/env; for hand-built bundles also hookelementor/editor/v2/scripts/register+scripts/enqueue. - Do not modify Elementor Core. Core packages live in
packages/packages/core/editor-*— reference only. - Runnable reference: examples/example-plugin/ (
editor-example-featureplain JS bundle).
Prerequisites
- Experiment
e_atomic_elements(and oftene_opt_in_v4) — getting-started/experiments.md. - In-editor MCP has no separate experiment gate beyond editor availability.
Read first: editor-packages/extending-editor.md, docs/atomic-builder/examples/add-editor-package.md. Monorepo package creation (Core contributors): packages/docs/creating-a-new-package.md.
Checklist
A. npm / webpack path (preferred for React UI)
- PHP: register package slug — append to
elementor/editor/v2/packages(e.g.editor-my-feature). Optional env viaelementor/editor/v2/scripts/env. - Build — webpack (or Vite) with
@elementor/*as externals resolved at runtime viawindow.elementorV2.*— see packages/docs/architecture.md and editor-packages/libs.md. - Output contract — bundle exposes
window.elementorV2.{camelCaseSlug}(e.g.editor-my-feature→editorMyFeature). Slug → global:kebabToCamelCaseinscripts/vite/shared/packages-externals.mjs(drop hyphens, uppercase the following letter). Core Vite build footer auto-calls?.init?.()for packages built into Core assets. - Enqueue your bundle —
wp_register_script()/wp_enqueue_script()with the plugin's own URL (e.g.plugins_url( 'assets/js/my-bundle.js', MY_PLUGIN_FILE )); the packages filter does not load third-party JS. src/init.ts(x)— synchronous registration only; re-export fromsrc/index.ts.
B. Hand-built script path (no npm pipeline)
- Hook
elementor/editor/v2/scripts/registertowp_register_script()your plugin JS (URL viaplugins_url( ..., MY_PLUGIN_FILE )) with deps on requiredelementor-v2-*handles. Common verified handles (fromcore/editor/loader/editor-loader.php+scripts/vite/build-packages.mjselementor-v2-${name}):elementor-v2-editor,elementor-v2-editor-app-bar,elementor-v2-editor-panels,elementor-v2-ui,elementor-v2-icons. - Hook
elementor/editor/v2/scripts/enqueueto enqueue that handle. - You must call
init()yourself — append at end of bundle:
window.elementorV2.editorMyFeature?.init?.();Adding the slug to elementor/editor/v2/packages alone does nothing if no Core .asset.php exists for that slug — manual script registration carries the load.
- No JSX build step — use
window.React+React.createElement(React is externalized as globalReactinscripts/vite/shared/packages-externals.mjs). - Slug → global — same
kebabToCamelCaserule as path A (e.g.editor-my-feature→window.elementorV2.editorMyFeature). - Late-loaded global alternative —
window.elementorV2.{camelCasePackage}for scripts enqueued after editor packages; see extending-editor.md.

C. Common init() work
- Pick injection API (read doc for full list):
- Shell:
injectIntoTop,injectIntoLogic(@elementor/editor) - App bar:
injectIntoPageIndication,toolsMenu(@elementor/editor-app-bar) - Editing panel:
injectIntoStyleTab,registerEditingPanelReplacement(@elementor/editor-editing-panel) - Elements panel:
injectTab(@elementor/editor-elements-panel) - Site Settings:
injectSiteSettingsTab(@elementor/editor-site-settings) - Slide-in panels:
registerPanel(@elementor/editor-panels;__registerPanelis a legacy alias) - Styles:
stylesRepository.register(@elementor/editor-styles-repository) - Legacy bridge:
registerDataHook,blockCommand,__privateListenTo( v1ReadyEvent(), fn )(@elementor/editor-v1-adapters)
- Shell:
- In-editor MCP only —
getMCPByDomain()+ Zod from@elementor/schema; namespace/^[a-z_]+$/. Not PHPmodules/mcp/abilities — see mcp/overview.md.
Verify
- Script loads in editor network tab;
window.elementorV2.{camelCaseSlug}exists. - UI renders in chosen slot.
- MCP tools visible when Angie / WebMCP is enabled.
Minimal init skeleton
import { injectIntoPageIndication, toolsMenu } from '@elementor/editor-app-bar';
export function init() {
injectIntoPageIndication( { id: 'my-indicator', component: MyIndicator } );
toolsMenu.registerToggleAction( { id: 'toggle-my-panel', priority: 20, useProps: useMyToggleProps } );
}Reference: packages/packages/core/editor-site-navigation/src/init.ts.
External implementation path
- Third-party plugin ships own editor bundle; filter
elementor/editor/v2/packages(+ manual script hooks for non-Core-built bundles). - Register MCP tools only for in-editor agent workflows via
@elementor/editor-mcp.
Core reference paths (do not edit)
- Core packages:
packages/packages/core/editor-*. - Pro extensions:
packages/packages/pro/editor-*-extended(elementor-pro sibling repo). - Loader:
core/editor/loader/.
