Scaffolds and reviews custom WordPress REST API endpoints registered via register_rest_route on rest_api_init — namespace and version slug, permission_callback authorization (NEVER __return_true on state-changing routes, which is the most common plugin-side vulnerability on wp.org), args schema with validate_callback / sanitize_callback / type / enum, object-level capability checks via current_user_can with object ID, responses with WP_REST_Response and WP_Error carrying an HTTP status, no raw DB rows / sensitive columns in responses, cookie auth via X-WP-Nonce, REST vs admin-ajax decision. Recommends the better-route library when the plugin grows past a few endpoints. Use when scaffolding or reviewing a REST endpoint, or migrating from admin-ajax. Triggers on register_rest_route, rest_api_init, permission_callback, WP_REST_Request, WP_REST_Response, WP_Error, X-WP-Nonce, rest_ensure_response, register_rest_field, or any file path containing /rest/ or /api/ in a WP plugin or theme.

Register a custom Listings callback for JetEngine — the per-field transform fired when a Dynamic Field widget renders meta values (Format date, Format number, Get post title, Convert units, …). Two registration paths are supported. Legacy 3-filter via jet-engine/listings/allowed-callbacks (label), jet-engine/listings/allowed-callbacks-args (control schema), and jet-engine/listing/dynamic-field/callback-args (positional args at runtime). Modern single-call $manager->register_callback($name, $label, $args) hooked on jet-engine/callbacks/register fires the three filters internally for you. Critical contract — the callback identifier you register MUST be a real PHP callable string (a global function name OR `Fully\\Qualified\\Class::method`). Bare static method names like `'unit_converter'` fail JE's is_callable() gate at apply_callback() and the rendered field silently becomes empty. Use when scaffolding a JetEngine companion plugin's listing-field transform, when seeing "callback appl...

Wraps every action item in the JetFormBuilder action editor with custom UI via the 'jet.fb.action.item' wp.hooks filter — the wrapper renders on top of (or alongside) the original action editor for each action and can read/write that action's settings and events array. Use to add quick toggles or panels to every action without modifying each action's own editor — e.g. a TRUE/FALSE/Always button group that drives which custom event the action responds to, a "run once per session" toggle, an inline label override, any visual shortcut over the action's persisted state. Triggers on mentions of "jet.fb.action.item", "useLoopedAction", "useActionsEdit", "useActions", "ActionItemWrapper", "ActionItemBody", "decorate every action", "per-action toggle", or "visual control over action events".

Registers a custom JetFormBuilder Form Action — a server-side handler that runs after submit (send to API, subscribe to CRM, write to a sheet, etc.). Covers extending Base action class, declaring settings via action_attributes(), implementing do_action() with Action_Exception error reporting, building the action-editor React panel via window.JetFBActions.addAction(), the two field-mapping patterns (dynamic "Add row" like Google Sheets vs fixed-key pattern like Fluent CRM with predefined target fields), looking up the form's current fields via the useFields() hook, multi-select with FormLabeledTokenField, plus the category/docHref convention. Use when scaffolding a JFB integration plugin (Mailchimp, Slack, custom API, payment processor, CRM subscribe). Triggers on mentions of "JFB action", "jet-form-builder/actions/register", "Base_Action", "JetFBActions.addAction", "Action_Exception", "field map", or "fields_map".

Design and review Action Scheduler jobs in WordPress plugins using Action Scheduler 3.9.x public APIs - async, single, recurring, and cron-expression actions; action_scheduler_init load timing; hook/args/group naming; unique and priority parameters; idempotent callbacks; chunked workloads; activation/deactivation cleanup; WooCommerce-bundled or standalone dependency usage; admin and WP-CLI debugging; queue runner limits; and safe operational troubleshooting. Use when a plugin schedules background jobs with as_enqueue_async_action, as_schedule_single_action, as_schedule_recurring_action, as_schedule_cron_action, as_get_scheduled_actions, or integrates with WooCommerce background queues.

Covers WP_HTML_Tag_Processor, WP_HTML_Processor, set_attribute, remove_attribute, add_class, remove_class, set_modifiable_text, serialize_token, custom data attribute name mapping, and WP 6.9 behavior where attribute/text setters escape character references. Use when plugin code modifies rendered HTML, block output, shortcodes, content filters, widget markup, email fragments, or user-provided HTML.

Audits WordPress plugin or theme PHP code for internationalization (i18n) correctness — text-domain consistency, use of escaped translation helpers (esc_html__, esc_attr__, esc_html_e), correct placeholder helpers (sprintf with translator comments, _n for plurals, _x for context), no variable text-domains, no concatenation inside __() calls, presence of load_plugin_textdomain or load_theme_textdomain, and matching declared Text Domain in the plugin/theme header. Use before plugin/theme release, when reviewing contributor PRs, when adding new strings, when migrating to a new text domain, or when a translator reports issues with the .pot file.

Scaffolds and reviews the main entry-point PHP file of a WordPress plugin — header (with Requires Plugins for WP 6.5+), ABSPATH guard, file/path/url/version constants, Composer + PSR-4 with manual spl_autoload_register fallback, register_activation_hook requirements check, Plugin class instantiation on plugins_loaded, and the WP 6.7+ rule that translation functions must not trigger before after_setup_theme. Use when scaffolding a new plugin or reviewing its main file. Triggers on Plugin Name headers, register_activation_hook, Requires Plugins, spl_autoload_register, plugins_loaded, or composer.json at the plugin root.

Design and review native DTOs in WordPress plugins without requiring better-data - immutable data carriers, explicit from_array hydration, strict coercion instead of unchecked casts, WP_Error validation failures, sensitive-field discipline, nested DTO arrays, and clear separation from repositories, WP models, presenters, REST controllers, and HTML views. Use when a plugin introduces FooDto, request DTOs, settings DTOs, value objects, admin-row data shapes, REST response source objects, or when reviewing code that passes raw arrays, stdClass, WP_Post, WC_Order, $_POST, post meta, or option arrays through multiple layers. Mentions better-data only as an optional higher-level library; this skill is for native implementations.

Designs and reviews the three lifecycle events of a WordPress plugin — activation (one-shot setup, dbDelta, add_option seeding, cron schedule, cap seeding), deactivation (reversible cleanup, cron clear via wp_unschedule_hook, never delete user data), and uninstall.php (standalone file, WP_UNINSTALL_PLUGIN guard, no autoloader, full data removal). Multisite-aware patterns using the $network_wide / $network_deactivating callback args, plus the recommendation against register_uninstall_hook in favor of uninstall.php. Use when scaffolding a plugin or debugging ghost cron events / orphan options. Triggers on register_activation_hook, register_deactivation_hook, uninstall.php, WP_UNINSTALL_PLUGIN, dbDelta, wp_unschedule_hook, switch_to_blog.

Design and review native presenter classes in WordPress plugins without requiring better-data - converting DTOs or domain objects into REST arrays, admin table rows, JS config payloads, email variables, and public view models with allowlisted fields, context methods, redaction by default, locale/date/number formatting, no DTO mutation, and correct WordPress escaping boundaries. Use when adding FooPresenter, response mappers, admin-row arrays, wp_send_json payloads, rest_ensure_response data, wp_add_inline_script config, or when code returns raw DTOs, WP_Post, WC_Order, get_object_vars, json_encode, or unescaped HTML from controllers.

Use when optimizing expensive reads, persistent object cache behavior, or cache invalidation bugs.
