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 | $0.00223 | $0.03305 |
| Opus 5.5 | $0.00089 | $0.01322 |
| Sonnet 5.5 | $0.00045 | $0.00661 |
| Haiku 4.5 | $0.00022 | $0.00331 |
Grade A, and why
elementor-experiments-and-markup scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 183 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Elementor: experiments and markup-changing features
For developers shipping a companion plugin / theme that adds widgets, dynamic tags, or frontend CSS/JS on top of Elementor. Elementor ships "experiments" (feature flags) under core/experiments/manager.php. Most are cosmetic, but two Performance experiments change the rendered HTML and are default-ON on new installs, so a modern addon must handle them or it silently breaks on a large share of sites.
Read this first — you cannot assume the state
Experiment state is per-site and three-valued (Default / Active / Inactive), and the effective default differs between fresh and upgraded installs. Never hardcode an assumption; detect at runtime:
if ( \Elementor\Plugin::$instance->experiments->is_feature_active( 'e_optimized_markup' ) ) {
// adapt markup
}
Verified: Experiments\Manager::is_feature_active( $name, $check_dependencies = false ) at core/experiments/manager.php:257; actual state resolves to the user's explicit state unless it's Default, then the feature's default (manager.php get_feature_actual_state).
The two markup-changing experiments (both release_status => STABLE, tag "Performance", new_site.default_active => true) — verified manager.php:312-381:
| Experiment | name |
Default on NEW install (≥ ver) | What it changes |
|---|---|---|---|
| Inline Font Icons | e_font_icon_svg |
ON (≥ 3.17.0) | Icons render as inline <svg>; Font Awesome + eicons CSS/fonts NOT loaded on frontend |
| Optimized Markup | e_optimized_markup |
ON (≥ 3.30.0) | Removes inner wrapper HTML (.elementor-widget-container) from widgets to shrink the DOM |
new_site.default_active => truemeans a site first installed at/after that version defaults the experiment ON. Sites upgraded from older versions may keep it OFF (e_optimized_markup/containerhavedefault => STATE_INACTIVE). So the SAME addon meets both states in the wild — which is exactly why you detect at runtime.
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.

elementor-experiments-and-markup is a skill published in the GitHub repository Lonsdale201/wp-agent-skills (25 stars, last pushed 7d ago), licensed MIT. It adds 223 tokens to every session and 3,305 once invoked, about $0.0009 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
