+  Type checker action
+
+description: |
+  Run a type checker on your Python project.
+
+inputs:
+  type-checker:
+    description: |
+      Type checker to be used. Supported type checkers are ``basedpyright``, ``mypy``, ``pyrefly`` and ``ty``.
+    required: true
+    type: string
+
+  optional-dependencies-name:
+    description: |
+      Any valid install targets defined in the ``pyproject.toml`` file, or the suffix
+      of a requirement file. Multiple targets can be specified as a comma-separated
+      list. The associated dependencies are installed before running the type checker and should include your type checker.
+      There is no default value, we suggest using a ``'ci_types'`` if you have extra dependencies for type checking.
+      Therefore, in case of a requirement file, the default file is ``requirements/requirements_ci_types.txt``.
+    required: true
+    type: string

+  # Optional inputs
+  python-version:
+    description: |
+      Python version used for installing and running your chosen type checker.
+    default: '3.12'
+    required: false
+    type: string
+
+  use-python-cache:
+    description: |
+      Whether to use the Python cache for installing previously downloaded
+      libraries. If ``true``, previously downloaded libraries are installed from the
+      Python cache. If ``false``, libraries are downloaded from the PyPI index.
+    required: false
+    default: true
+    type: boolean
+
+  type-checker-extra-args:
+    description: |
+      Set of additional arguments passed to the type checker in the form of a string.
+    default: ''
+    required: false
+
+  checkout:
+    description: |
+      Whether to clone the repository in the CI/CD machine. Default value is
+      ``true``.
+    default: true
+    required: false
+    type: boolean
+
+  skip-install:
+    description: |
+      Skip installation process. This should be set to `false` when using poetry
+      as the build-backend because it should be false with poetry as build-backend.
+      The default value is ``false``.
+    default: false
+    required: false
+    type: boolean
+
+  use-uv:
+    description: |
+      Whether to use uv as the default package manager instead of pip. Default value is ``true``.
