 Update hook dependency pins
#############################

``prek update --freeze`` moves pre-commit hook revisions to commit SHAs. Use ``release-creator hooks`` in the same
weekly change to pin packages declared by Python hook repositories and packages in ``additional_dependencies``:

.. code-block:: bash

    prek update --freeze --cooldown-days 7
    release-creator hooks --exclude-newer '7 days' --python-version 3.15
    prek run --all-files

The command checks out each external hook repository at its frozen commit and reads ``.pre-commit-hooks.yaml``. For
selected Python hooks, it resolves the repository package with any exact ``additional_dependencies`` and adds the pinned
closure to that hook's ``additional_dependencies``. It also resolves exact dependencies in local hooks. Conditional
dependencies remain conditional, so a Windows-only package does not install on Linux. Non-Python hooks are unchanged.

Generated pins have a ``# release-creator managed`` marker. The next update replaces them. Direct pins retain their
spelling and comments; a flow-style list becomes a block list when the closure adds packages. A range such as
``mdformat-gfm>=1`` stays as written and is not a resolution root. Use the Python version that the hooks run with; the
cutoff excludes newly published packages.

If uv cannot resolve every pinned package, the command fails without changing the file. Review the patch and run
``prek`` before opening the update PR. The command does not update hook revisions, project requirements, or
``pylock.toml``; the weekly workflow handles those separately.
