+# Cacti hmib Plugin AI Instructions
+
+## Project Overview
+This is a Cacti plugin. It integrates with the Cacti monitoring platform via the plugin hook architecture.
+
+## Technology Stack
+- PHP 7.4+ (targeting Cacti 1.2.x compatibility)
+- MySQL/MariaDB via Cacti's DB abstraction layer
+- PSR-12 coding standards
+
+## Key Rules
+- Use prepared statements (db_execute_prepared, db_fetch_row_prepared, etc.) for ALL queries with variables
+- Use get_request_var() / get_filter_request_var() for ALL user input, never raw $_REQUEST/$_GET/$_POST
+- Use html_escape() / htmlspecialchars() for ALL output of DB/user values in HTML context
+- Use cacti_escapeshellarg() for ALL shell command arguments
+- No PHP 8.0+ features (str_contains, match, union types, named args) - target PHP 7.4
+- Use ?? and ??= operators (PHP 7.4) instead of isset() ternary patterns
+- All unserialize() calls must use allowed_classes => false
+
+## Testing
+- Tests in tests/ directory
+- Use Pest PHP or PHPUnit
+- php -l lint check required before commit
