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.

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 | $0.00115 | $0.01761 |
| Opus 5 | $0.00057 | $0.00881 |
| Sonnet 5 | $0.00023 | $0.00352 |
| Haiku 4.5 | $0.00012 | $0.00176 |
Grade A, and why
wordpress-security 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 2d 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 — 214 lines — stays where its author put it; the contents beside it link to each section on GitHub.
WordPress Security Best Practices
This skill covers WordPress security patterns including output escaping, input sanitization, nonce verification, capability checks, and secure database queries.
Output Escaping
Every piece of dynamic data rendered in HTML must be escaped. Choose the function matching the output context:
| Context | Function | Example |
|---|---|---|
| HTML body | esc_html() |
<p><?php echo esc_html( $name ); ?></p> |
| HTML attribute | esc_attr() |
<input value="<?php echo esc_attr( $val ); ?>"> |
| URL/href | esc_url() |
<a href="<?php echo esc_url( $link ); ?>"> |
| Textarea content | esc_textarea() |
<textarea><?php echo esc_textarea( $text ); ?></textarea> |
| Inline JS value | esc_js() |
onclick="alert('<?php echo esc_js( $msg ); ?>')" |
| Rich HTML (post content) | wp_kses_post() |
<?php echo wp_kses_post( $content ); ?> |
| Custom allowed HTML | wp_kses() |
echo wp_kses( $html, $allowed_tags ); |
Translation + escaping combos:
esc_html__()/esc_html_e()— translatable escaped stringsesc_attr__()/esc_attr_e()— translatable escaped attributeswp_kses_post()on__()output for rich translated content
Input Sanitization
Sanitize all user input immediately upon receipt, before storage or processing:
| Data Type | Function |
|---|---|
| Plain text | sanitize_text_field( wp_unslash( $_POST['field'] ) ) |
| Textarea | sanitize_textarea_field( wp_unslash( $_POST['field'] ) ) |
sanitize_email( $_POST['email'] ) |
|
| Integer | absint( $_POST['id'] ) or intval( $_POST['num'] ) |
| Filename | sanitize_file_name( $_FILES['file']['name'] ) |
| HTML class | sanitize_html_class( $_POST['class'] ) |
| Key/slug | sanitize_key( $_POST['key'] ) |
| Title/slug | sanitize_title( $_POST['title'] ) |
| URL | esc_url_raw( $_POST['url'] ) (for storage — use esc_url() for display) |
Always wp_unslash() superglobals before sanitizing — WordPress adds slashes to $_GET, $_POST, $_REQUEST.
What ships with it
1 file 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.

wordpress-security is a skill published in the GitHub repository iwritec0de/wp-dev (1 stars, last pushed 4mo ago), licensed MIT. It adds 115 tokens to every session and 1,761 once invoked, about $0.0006 per session on Opus 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 2026-08-31.
