Why doesn't Typescript linter see types in global.d.ts?

Question

typescript

Good morning.
There is global.d.ts, where a couple of types are declared.

declare type KeyObject = { ... };
declare type AddressedKeyObject = { ... };

The goal is to use these types in other declaration files. It is logical to assume that since global.d.ts declares everything in the global scope, as it follows from the documentation, these types will be available everywhere. However, the tsc utility does not see them during operation, and fails with the message "Cannot find name KeyObject". An example of a declaration file that fails:

declare module "@vendor/something" {
    export function getKeyObject(): KeyObject;
}

How to fix? What have I done wrong?
Thanks in advance.

Answer 1

tsc is not a linter, but the globals.d.ts compiler
must be connected to the project in one way or another. in tsconfig.json or ///
did you do that?
for ease of verification, add /// to some file with an error
