How to create a pre-commit.com hook that runs an entry which is located in the same repository

I would like to create a repository for pre-commit.com hook with a hook that runs an entry located within this repository.

I have created a repository with a hook:

my-pre-commit-hook> ls -a
.pre-commit-hooks.yaml
my-script.py

with .pre-commit-hooks.yaml:

- id: my-check
  name: my-check
  entry: python
  args: [my-script.py]
  language: system
  files: '.*'

Then, from another repository I run

pre-commit try-repo ../my-pre-commit-hook

but it fails with

... can't open file '.../my-script.py': [Errno 2] No such file or directory

I would expect that pre-commit.com provides some variable which I can use in .pre-commit-hooks.yaml to find my-script.py, for example

- id: my-check
  name: my-check
  entry: python
  args: [$PRE_COMMIT_REPO/my-script.py]
  language: system
  files: '.*'

I don't see much advantage of installing this script like https://github.com/pre-commit/pre-commit-hooks/blob/main/setup.cfg does since I have very simple script which can run from source.

Language script allows entry relative to the root of the hook repository, https://pre-commit.com/#script:

The entry should be a path relative to the root of the hook repository.
