The `insert-license` pre-commit hook runs [skywalking-eyes](https://github.com/apache/skywalking-eyes) (via the `apache/skywalking-eyes` Docker image, so a running Docker daemon is required) to stamp the standard Apache-2.0 header (`Copyright 2026 DataRobot, Inc. and its affiliates.` followed by the standard "Licensed under the Apache License, Version 2.0" notice) into every `.py` file, and the companion `insert-license-notebooks` hook stamps the same notice into a leading markdown cell of every notebook the first time you run `task pre-commit`.

-- Jupyter notebooks (``.ipynb``): insert a markdown cell at index 0

-
-Idempotent: files that already carry the correct header are skipped, so

+"""Insert/refresh the project license header cell in Jupyter notebooks.
+
+skywalking-eyes (the ``insert-license`` hook) stamps license headers into
+source files but cannot process ``.ipynb`` notebooks. This companion hook
+covers notebooks: it ensures the first cell is a markdown cell carrying the
+same license text, deriving that text from ``.licenserc.yaml`` so there is a
+single source of truth shared with skywalking-eyes.
+
+Cell outputs are preserved via ``nbformat.read`` / ``nbformat.write`` (some
+repositories deliberately commit executed notebook outputs).
+
+Idempotent: exits 1 (and lists the modified files) only when a notebook
+needed its header inserted or refreshed, 0 otherwise. Matches pre-commit's
+expected autofix-hook behavior.
