# Task library

Mechanic's **task library** is a compendium of e-commerce automation tasks and documentation, written by the Mechanic community and the Mechanic core team. [Hosted on GitHub](https://github.com/lightward/mechanic-tasks), everything is open-sourced under the highly permissive [MIT license](https://github.com/lightward/mechanic-tasks/blob/master/LICENSE), making all library tasks appropriate for re-use and modification.

**To browse the task library, visit** [**tasks.mechanic.dev**](https://tasks.mechanic.dev/)**.**

## Popular automations merchants install first

If you already know the automation you want Mechanic to handle, start with a task that's close:

* **Keep bundle and shared-SKU inventory aligned** — maintain bundle stock with [Maintain inventory for a product bundle](https://tasks.mechanic.dev/maintain-inventory-for-a-product-bundle), or sync variants with [Sync inventory for shared SKUs](https://tasks.mechanic.dev/sync-inventory-for-shared-skus).
* **Move, hide, publish, or sort products by rule** — move sold-out products with [Move out-of-stock products to the end of a collection](https://tasks.mechanic.dev/move-out-of-stock-products-to-the-end-of-a-collection), hide them with [Hide out-of-stock products](https://tasks.mechanic.dev/hide-out-of-stock-products), or publish new products automatically with [Auto-publish new products](https://tasks.mechanic.dev/auto-publish-new-products).
* **Fulfill or manage orders automatically** — fulfill digital or no-shipping items with [Auto-fulfill items that don't require shipping](https://tasks.mechanic.dev/auto-fulfill-items-that-dont-require-shipping), or close stale pending orders with [Cancel and close unpaid orders after x hours/days](https://tasks.mechanic.dev/cancel-and-close-unpaid-orders-after-two-days).
* **Tag wholesale, VIP, discount, or matching-product orders** — copy customer tags with [Auto-tag orders based on customer account tags](https://tasks.mechanic.dev/auto-tag-orders-based-on-customer-account-tags), copy discount codes with [Auto-tag orders by discount code](https://tasks.mechanic.dev/auto-tag-orders-by-discount-code), or tag orders that contain a matching product with [Auto-tag orders that contain a matching product](https://tasks.mechanic.dev/auto-tag-orders-that-contain-a-matching-product).
* **Email customers at the right moment** — email customers when an order is tagged with [Email customers when their order is tagged](https://tasks.mechanic.dev/email-customer-when-order-tagged), when tracking appears with [Email the customer when tracking numbers are added to their order](https://tasks.mechanic.dev/email-the-customer-when-tracking-numbers-are-added-to-their-order), or after they buy a product with [Email customers after purchasing a certain product](https://tasks.mechanic.dev/product-order-email).
* **Export CSV or PDF reports** — email order data with [Email a CSV export of orders](https://tasks.mechanic.dev/email-a-csv-export-of-orders), create PDF invoices with [Send a PDF invoice when an order is created](https://tasks.mechanic.dev/send-a-pdf-invoice-when-an-order-is-created), or build from a PDF example like [Generate a simple product catalog PDF](https://tasks.mechanic.dev/generate-a-simple-product-catalog-pdf).

These are starting points, not limits. Once installed, a task can be configured, copied, modified, or used as a pattern for something custom.

## Installing a task

1. Navigate to the **Add task** page in the Mechanic app to find a task that fits your needs. You can also browse [tasks.mechanic.dev](https://tasks.mechanic.dev/) to explore the library.
2. In the app, click **Install this task** to add the task to your Mechanic account
3. Configure any task options (settings fields) as needed
4. Click **Save** to activate the task

Once installed, a library task is your own copy. You can modify the code, change options, or adjust subscriptions to fit your specific requirements.

{% hint style="info" %}
When building a new task, it's often easier to start from an existing library task and modify it, rather than writing a task from scratch. Searching [tasks.mechanic.dev](https://tasks.mechanic.dev/) is a good place to start.
{% endhint %}

{% hint style="warning" %}
Mechanic support covers **unmodified** tasks from the task library. Once you modify a library task's code, it becomes a custom task, and support is limited to platform-level issues. For help with custom tasks, see [Get help with a custom task](/custom-help.md)
{% endhint %}

## What's in the library

The library includes hundreds of tasks covering common Shopify automation patterns, including:

* **Tagging** — auto-tag orders, customers, and products based on conditions
* **Notifications** — send emails, Slack messages, or other alerts on Shopify events
* **Inventory** — monitor stock levels, sync inventory across locations
* **Order management** — fulfill, cancel, or modify orders automatically
* **Product management** — publish, hide, or update products based on rules
* **Data feeds** — generate scheduled CSV or email reports
* **Integrations** — connect with external services like Google Sheets, Airtable, and more
