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 | $0.00078 | $0.02639 |
| Opus 5 | $0.00039 | $0.01319 |
| Sonnet 5 | $0.00016 | $0.00528 |
| Haiku 4.5 | $0.00008 | $0.00264 |
Grade A, and why
ci4-advanced 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 9d 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.

CodeIgniter 4 -- Advanced Patterns Reference
How to make CI4's subsystems (autoloader, migrations, seeds, commands, routes, filters, config) work from code that lives outside the standard app/ directory. Covers both documented-but-underused features and runtime techniques the docs don't explain.

Runtime Namespace Registration
CI4 docs show static PSR-4 mapping in Config/Autoload.php. But service('autoloader')->addNamespace() lets you register namespaces at runtime -- essential when you don't know what code exists until the app boots.
// Static (docs show this) -- known at deploy time
// app/Config/Autoload.php
public $psr4 = [
APP_NAMESPACE => APPPATH,
'Acme\Blog' => ROOTPATH . 'acme/Blog', // fixed path
];
// Runtime -- discovered at boot time
service('autoloader')->addNamespace('Plugins\\Store', ROOTPATH . 'plugins/Store/');
After runtime registration, all CI4 subsystems find classes in that namespace: controllers, models, migrations, commands, View Cells, filters.
See references/runtime-namespaces.md for two-phase boot (web vs CLI) and timing constraints.
Running Subsystems from External Namespaces
Once a namespace is registered (statically or at runtime), CI4's subsystems can target it:
Migrations
// Run migrations for a specific namespace only
$migrate = \Config\Services::migrations();
$migrate->setNamespace('Plugins\\Store')->latest();
What ships with it
4 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.

ci4-advanced is a skill published in the GitHub repository enlivenapp/Codeigniter4-App-and-API-Skills-for-Claude-Code (22 stars, last pushed 5mo ago), licensed MIT. It adds 78 tokens to every session and 2,639 once invoked, about $0.0004 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 2026-08-30.
