**Error** from the compiler, while it builds your `.tsrx` files.

## What happened

In a `.tsrx` file, Markless treats `state`, `computed`, `element`, `shared`, and `storage` as its own names. This call uses one of those names, but the name does not come from an import of `@markless/core`.

Markless prints the message, the reason, and a suggestion:

```text
MARKLESS_FRAMEWORK_IMPORT_REQUIRED: `<callSource>` calls your local function `<apiName>`, but in `.tsrx` files `<apiName>` is a compiler-recognized markless API name. Rename the local function, or import the framework API from `@markless/core`.
The compiler recognizes `state`/`computed`/`element`/`shared`/`storage` by name in `.tsrx` reactive scopes so that graph ownership stays unambiguous for readers and tools.
Rename the helper (before: `function <apiName>(value) { ... }` — after: `function doubleValue(value) { ... }`), or, if graph state was intended, delete the helper and add `import { <apiName> } from '@markless/core';`.

```

Words in angle brackets change from case to case.

## How to fix it

If you meant the Markless function, import it. If you wrote your own helper with that name, rename the helper.

```tsrx
import { state } from '@markless/core';
```

## Where it comes from

`@markless/compiler` raises this code. Source:
