# Key concepts

> Lines, skills, recipes, credits, the Vault, and galleries — the words the product actually uses.

These words are used the same way on the site, in the API, and here.

## Line

A run is a **line of steps**. Each step is handed the file the step above made.

Whether one skill can sit under another is decided by what the earlier skill hands on — a picture, a video, audio, or a [set](/workbench#sets) of files. Two skills that each make a set cannot share one line.

## Skill

A **skill** is one unit of work: remove a background, burn captions, generate an image. Every live skill has a page at `mediamonster.app/skills/<slug>` and an API slug of the same name.

Skills are not the same as the browser page steps on the Workbench (**Save as**, **Resize**, **Adjust**, **Put it on a background**, **File it in the Vault**). Those run in the tab and do not appear in `GET /api/v1/skills`.

See [Skills](/skills/overview).

## Recipe

A **recipe** is a named line of existing skills, not a fused skill. The catalogue on `/recipes` is the same six recipes for everyone. Yours live on `/my-recipes` and are capped by plan.

Opening a recipe lays the steps onto the Workbench. Nothing runs until you press **Run**.

See [Recipes](/recipes).

## Credits

**Credits** are what the UI charges. They come off before a provider is called, and go back if that run fails.

* Monthly plan credits reset on the billing date.
* Top-up credits never expire.
* Cyclops includes **0** monthly credits.

See [Credits and plans](/getting-started/credits-and-plans).

## Vault

The **Vault** is stored media — uploads and Workbench results. It is separate from a conversion job: those files are deleted when the job finishes unless you save them.

Cyclops keeps Vault files for **30 days**. Paid plans keep them until you delete them.

See [Vault](/vault).

## Galleries

**Galleries** (desktop rail: **Deliveries**, phone tab: **Sends**, page title: **Deliveries**) are client packs built from Vault files. A live gallery has a public review link on `mediamonster.link`.

Kraken and Behemoth can hide the Mediamonster line. Cyclops and Minotaur cannot.

See [Galleries](/galleries).

## Queue

The **Queue** is every run — running first, then history. The last 100. Open a row to put it back on the Workbench.

See [Queue](/queue).

## Keys

**Keys** unlock REST and MCP. They start `mm_live_` and are shown once. API access comes with Minotaur, Kraken, and Behemoth — not Cyclops.

See [Authentication](/api/authentication).
