+- **Skill** `pollora-hooks`: asynchronous actions — `->async()` and `#[Async]`, their options, what travels and what is refused, `capture()` / `when()`, drivers and what must run them, the rules for a replayable handler, `Async::fake()`, `pollora:async:list` and `pollora:make:action --async`
+- **Core and 13.x guidelines**: `#[Async]` in the attribute snippet, the `pollora:async:list` command, the async checks of `pollora:doctor`

 ### Request Lifecycle
 
+Asynchronous actions, from v13.35.2 (`pollora/hook` `^1.4`): `Action::add(...)->async()` or `#[Async]` next to `#[Action]` queues the handler instead of running it in the request. The default driver `auto` takes the Laravel queue only once `HOOKS_ASYNC_CONNECTION` is set, then Action Scheduler, then WP-Cron; Pollora sets `DISABLE_WP_CRON`, so WP-Cron and Action Scheduler need a system cron, the queue a worker. A handler may run twice and in any order: make it safe to replay. See the `pollora-hooks` skill.
+
 WordPress is loaded from a service provider's `boot()`; `wp()` runs there. Since v13.35.1, `template_redirect` (then `pollora_loaded`) fires once every provider has booted, still before routing, so a plugin or theme rendering a view from `template_redirect` gets the theme's view composers and shared data. Code that relied on `template_redirect` having fired during the providers' boot must move to a later hook.

+## Asynchronous Actions
+
+An action whose work is slow or calls a third party (CRM, ERP, email, indexing) can run after the request: it is queued when the hook fires, then run by a Laravel queue worker, Action Scheduler or WP-Cron. Only actions: a filter returns a value and cannot be deferred.
+
+```php
+use Pollora\Attributes\Action;
+use Pollora\Attributes\Async;
+use Pollora\Hook\Async\AsyncContext;
+
+class SyncEventToCrm
+{
+    #[Action('save_post_event', priority: 20)]
+    #[Async(tries: 3, unique: true, when: 'isRealSave', capture: 'captureStatus')]
+    public function handle(int $postId, CrmClient $crm, AsyncContext $context): void
+    {
+        // $crm comes from the container; $context->get('status') was recorded at trigger time
+    }
+
+    public function isRealSave(int $postId): bool
+    {
+        return ! wp_is_post_revision($postId) && ! wp_is_post_autosave($postId);
+    }
+
+    public function captureStatus(int $postId): array
+    {
+        return ['status' => get_post_status($postId)];
+    }
+}
+
+// Same with the facade
+Action::add('woocommerce_order_status_completed', [OrderExporter::class, 'export'])
+    ->async()->delay(60)->tries(3)->backoff([30, 300])->onQueue('integrations');
+```
+
+- Options (chained or named on `#[Async]`): `delay`, `via` (`queue`, `action-scheduler`, `wp-cron`, `sync`), `onQueue`, `unique` (`true` or seconds), `tries`, `backoff`, `asUser`, `capture`, `when`, `keepMissing`, `except` (hooks that stay synchronous).
+- `#[Async]` on a class applies to every `#[Action]` method; a method's own `#[Async]` replaces it.
+- An `#[Async]` that cannot be honoured (unknown hook in `except`, missing or non-public `capture`/`when`, invalid `tries`/`backoff`/`unique`, on a `#[Filter]`, without `#[Action]`) is logged and the action **runs synchronously**; `pollora:doctor` lists it.
+- Arguments travel as values; `WP_Post`, `WP_Term`, `WP_User`, `WP_Comment` and Eloquent models travel by ID and are reloaded at execution. Any other object is refused. Capture an ID, never a secret: captured values sit in the database until execution.
+- The handler runs without a current user unless `asUser`; site and locale are restored.
+- Default driver `auto`: the Laravel queue only once `HOOKS_ASYNC_CONNECTION` is set, then Action Scheduler, then WP-Cron. `config/hooks.php`: `php artisan vendor:publish --tag=pollora-hooks`. `HOOKS_ASYNC_DRIVER=sync` runs everything at once in development.
+- **Something must run the queue**: Pollora sets `DISABLE_WP_CRON`, so WP-Cron and Action Scheduler need a system cron requesting `wp-cron.php`; the queue needs `php artisan queue:work`.
+
+Rules to respect in the handler:
+- **At least once**: a retry or a double trigger can run it twice — make it safe to replay (check before sending, upsert).
+- **No order** between asynchronous actions on the same hook, and a **variable delay**.
+- **Prefer a class to a closure**: a class runs the deployed code, a closure the code as it was when queued.
+- It cannot redirect, print, or change what the current request reads.
+
+Testing:
+
+```php
+use Pollora\Hook\Async\Async;
+
+Async::fake();
+// ... fire the hook
+Async::assertDispatched(SyncEventToCrm::class, fn ($payload, int $delay) => $payload->captured['status'] === 'publish');
+Async::assertDispatchedTimes(SyncEventToCrm::class, 1);
+Async::runDispatched(); // run what was recorded
+```
+
+`php artisan pollora:async:list` shows every asynchronous action, its driver and options, and where the default driver comes from.
+
 ## Generating Hook Classes
 
 ```bash
 php artisan pollora:make:action MyAction
+php artisan pollora:make:action SyncEventToCrm --hook=save_post_event --async   # with #[Async]
 php artisan pollora:make:filter MyFilter
 ```
