Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00112 | $0.02722 |
| Opus 5 | $0.00056 | $0.01361 |
| Sonnet 5 | $0.00022 | $0.00544 |
| Haiku 4.5 | $0.00011 | $0.00272 |
Grade A, and why
elementor-v3-widget-development scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 210 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Elementor V3 widget development
Build companion-plugin widgets on Elementor's established Widget_Base / Controls_Stack architecture. Treat V3 here as the classic editor/widget model, not as an installed Elementor 3.x version: this API remains available and is used by core widgets in Elementor 4.2.3.
Do not mix this model with Atomic Widgets / Editor V4. Atomic widgets extend classes under Elementor\Modules\AtomicWidgets, declare prop types and styles differently, and remain a moving surface. Never translate a V3 control array into an Atomic schema by guesswork.
When to use this skill
- Create or review a class extending
\Elementor\Widget_Base. - Register widgets, categories, scripts, or styles from an Elementor addon.
- Implement
register_controls(),render(),content_template(), orrender_plain_content(). - Add widget frontend JavaScript through
frontend/element_ready/{widget-name}.default. - Decide whether
is_dynamic_content()may returnfalse. - Diagnose a widget visible in PHP but missing/broken in the editor or frontend.
- Migrate
_register_controls()orelementor/widgets/widgets_registeredto current APIs.
For a complete companion-plugin skeleton and test matrix, read references/widget-contract-and-example.md. Load elementor-v3-widget-controls as well when designing or reviewing the control schema.
Architecture boundary
Use the following identity test before editing:
| Model | Base/signals | This skill |
|---|---|---|
| Classic V3 widget | Elementor\Widget_Base, Controls_Manager, register_controls(), render() |
In scope |
| Atomic / Editor V4 | Modules\AtomicWidgets, Atomic_Widget_Base, prop types, Atomic controls/styles |
Out of scope |
| Elementor plugin version | ELEMENTOR_VERSION, currently 4.2.3 in the tested install |
Independent of the model name |
Allow both models to coexist in a plugin only behind separate classes and registration paths. Do not make Atomic feature flags a prerequisite for a classic widget.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
