Use whenever the user is working inside a Perfex CRM codebase and touches `get_option`, `update_option`, `add_option`, `delete_option`, `hooks()`, `do_action`, `apply_filters`, `register_activation_hook`, `$this->load`, `get_instance()`, `$CI`, `db_prefix()`, auth helpers like `is_staff_logged_in` / `get_staff_user_id` / `staff_can`, or `_l()`. Also trigger when the user says "my Perfex get_option returns empty", "the hook isn't firing", "how do I hook into Perfex", "module-wide option", "Per...

Use whenever the user is reading, writing, installing, or debugging Perfex CRM custom fields — `tblcustomfields` (definitions), `tblcustomfieldsvalues` (values keyed by `relid`), field types (`input`, `textarea`, `number`, `select`, `multiselect`, `checkbox`, `date_picker`, `date_picker_time`, `link`, `colorpicker`), `fieldto` values (`contacts`, `customers`, `leads`, `invoice`, `estimate`, `contracts`, `tasks`, `tickets`, etc.), `only_admin` visibility, `show_on_client_portal`, `bs_column`, ...

Use whenever the user writes SQL DDL for a Perfex CRM module, adds a foreign key referencing `tblcontacts`, `tblstaff`, `tblclients`, `tblinvoices`, or any `tbl*` core table, designs `tbl<module>_<entity>` schema, writes `install.php` / `uninstall.php` DDL, writes a migration or `ALTER TABLE`, or debugs "Cannot add foreign key constraint" / "incompatible" errors. Also trigger when the user says "FK won't create in Perfex", "my module's table has wrong collation", "schema in staging differs fr...

Use whenever the user is sending, rendering, or debugging transactional email in a Perfex CRM module — `$this->emails_model->send_simple_email`, `send_mail_template`, email template files under `views/emails/`, admin-recipient fallback chains (`my_module_admin_email` → `contact_form_notification_email` → `smtp_email`), retry queues with exponential backoff stored in `tbl<module>_email_retries`, or cron-driven retry processing via `register_cron_task()` / `after_cron_run`. Also trigger when th...

Use whenever the user is creating, modifying, or debugging a Perfex CRM module — anything under `modules/<module_name>/` including `module_name.php`, `install.php`, `uninstall.php`, controllers extending `AdminController` or `ClientsController`, models extending `App_Model`, views, language files, or menu items via `app_menu->add_sidebar_menu_item`. Also trigger when the user says "my Perfex module won't install", "activation hook not running", "the module doesn't show up in Setup", "controll...

Use whenever the user is creating, modifying, or debugging a Perfex CRM payment gateway module — a class extending `App_gateway` in `modules/<module>/libraries/<Id>_gateway.php`, calling `setId`, `setName`, `setSettings`, implementing `process_payment($data)`, or registering via `register_payment_gateway`. Also trigger when the user says "create a payment gateway for Perfex", "my gateway webhook gets CSRF blocked", "process_payment not firing", "Stripe/PayPal/Mollie integration for Perfex", "...

Use whenever the user is customizing, overriding, or debugging PDF output in Perfex CRM — invoice PDFs, estimate PDFs, proposal PDFs, payment receipts, contract PDFs, statement PDFs, credit note PDFs, the `my_` prefix override convention, TCPDF library usage, `App_items_table` customization, font configuration (freesans, dejavusans, droidsansfallback), PDF merge fields, logo/heading settings, or e-invoice JSON/XML export (3.4.0+). Also trigger when the user says "my PDF is blank", "Arabic tex...

Use whenever a Perfex CRM task touches security-sensitive code — issuing or consuming single-use tokens (password reset, magic link, confirmation), race-safe atomic UPDATE with `affected_rows()` check, handling user-controlled redirect URLs (`?next=`, `?redirect=`, `?return_to=`), rate-limiting an AJAX endpoint that leaks boolean state, cross-module model loads, logging PII, adding `target="_blank"` links, or excluding a webhook from CSRF. Also trigger when the user says "my magic link works ...

Use whenever the user is building or debugging a Perfex CRM custom client-area theme — files under `assets/themes/<theme>/` and `application/views/themes/<theme>/`, asset injection via `app_customers_head`/`app_customers_footer`/`app_admin_head`/`app_admin_footer` hooks, overriding core views, dark mode with `[data-theme="dark"]` plus anti-FOUC `<head>` scripts, RTL/Arabic support, or the jQuery Validate bug where a submit button's `name` is stripped from POST (breaks "Pay Now" / "Save Draft"...
