Descripció
The problem Omni Guard solves:
Prevents WordPress White Screen of Death from missing plugin dependencies. Static scanner, runtime guard, pre-flight checks. Free.
This happens constantly. WordPress has no built-in protection for it. Omni Guard fills that gap.
How it works — four layers of protection:
1. Static Scanner
Analyses the PHP source code of all active plugins using PHP’s tokeniser (no regex, no exec). Builds a dependency map: which plugin calls functions defined in which other plugin. Runs twice daily via WP-Cron and whenever a plugin is activated or deactivated.
2. Runtime Error Handler
Registers a set_error_handler() and register_shutdown_function() at priority 1, before any other plugin fires. If an undefined function call occurs at runtime, Omni Guard catches it, logs the incident, and — in admin — shows a clean recovery page instead of a blank screen.
3. Dependency Pre-flight Check
On every admin request, reads the dependency map and verifies that every mapped cross-plugin function actually exists right now. If any is missing, an admin notice fires before any plugin code tries to call it.
4. Developer Safety Shims — og_call(), og_exists(), og_guard()
Global helper functions that plugin developers can use to make their cross-plugin calls crash-proof:
`php
// Returns WP_Error if missing — never crashes
$result = og_call( ‘some_plugin_function’, $arg1, $arg2 );
// Boolean existence check
if ( og_exists( ‘some_plugin_function’ ) ) { … }
// Call with a fallback
$result = og_guard( ‘some_plugin_function’, fn() => ‘default’, $arg1 );
`
Admin Dashboard includes:
* Live dependency health overview with KPI cards
* Full dependency map (filterable by risk level: high / medium / low)
* Incident log with detection method, timestamp, URL, and alert status
* Pre-flight status: functions missing right now
* Settings: scan depth, email alerts, whitelist, ignore list, danger zone
Email alerts are throttled to once per function per hour, with a maximum of 5 per day, to avoid noise.
Zero impact on production performance — scanning runs in WP-Cron background jobs. The runtime guard adds a single error handler registration at init. No database queries on the frontend unless a pre-flight is triggered.

PMF
-
Does this fix missing dependencies?
-
No. It prevents your site from crashing when they go missing, logs the incident, and alerts you. You still need to re-activate the missing plugin or remove the dependency.
-
Does the scanner modify any plugin files?
-
Never. Omni Guard is read-only at the filesystem level. It analyses files but never writes to them.
-
Will this slow down my site?
-
No. Scanning runs in WP-Cron background tasks. The runtime guard registers one error handler — effectively zero overhead.
-
What PHP version is required?
-
PHP 8.0 or higher (uses match expressions, named arguments, first-class callables).
-
What is a risk level?
-
High (3): Functions related to auth, payment, security, or sanitisation.
Medium (2): Data functions — get_, set_, update_, delete_, etc.
Low (1): Utility/helper functions unlikely to cause data loss if missing.
