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 5.1 | $0.00072 | $0.00599 |
| Opus 5.5 | $0.00029 | $0.00240 |
| Sonnet 5.5 | $0.00014 | $0.00120 |
| Haiku 4.5 | $0.00007 | $0.00060 |
Grade A, and why
processwire-page-classes 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 — 68 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ProcessWire Custom Page Classes
Custom page classes let you extend ProcessWire's Page with template-specific methods and properties. Every page using a given template becomes an instance of your custom class.
Quick Setup
- Enable in
/site/config.php:
$config->usePageClasses = true;
- Create class in
/site/classes/matching the template name:
| Template | Class | File |
|---|---|---|
home |
HomePage |
HomePage.php |
blog-post |
BlogPostPage |
BlogPostPage.php |
basic-page |
BasicPagePage |
BasicPagePage.php |
Rule: PascalCase the template name + append Page.
- Minimal class:
<?php namespace ProcessWire;
class HomePage extends Page {}
Essential Pattern — Custom Properties via get()
public function get($key) {
if($key === 'authorName') return $this->getAuthorName();
return parent::get($key);
}
This makes $page->authorName work as a virtual property.
API Access Inside Classes
// Correct — always use wire()
$this->wire()->pages->find('template=blog-post');
$this->wire()->sanitizer->text($value);
// Works but NOT preferred — not multi-instance safe
$this->pages;
pages()->find('template=product');
Property Access Gotcha
Inside the class, $this->property accesses the property directly, bypassing the get() method's lazy loading. For example, $this->template may return null, while $page->template (external) returns a Template object. Use $this->get('property') for consistent behavior.

What ships with it
6 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.

processwire-page-classes is a skill published in the GitHub repository gebeer/processwire-ai-docs (11 stars, last pushed 4mo ago), licensed MIT. It adds 72 tokens to every session and 599 once invoked, about $0.0003 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 2026-08-31.
