Greptile Summary

This PR enables the license-header-check CI workflow to cover files under the skills/ directory by adding skills/** to included_file_patterns and excluding skills/README.md, skills/.gitignore, and skills/docs/**.

• The recursive skills/** glob correctly captures source files (.cpp, .cu, .hpp, .java, .scala, .sql, template scripts) that need copyright headers, and the exclusions handle the top-level doc files.
• However, SKILL.md files in each subdirectory and skills/udf-gen-test/templates/scala/.mvn/jvm.config are matched by skills/** but are not excluded; these files do not carry a standard copyright comment header (the SKILL.md files use YAML front matter with a license: field rather than an SPDX comment block), so the check will fail for any PR that touches them.

Confidence Score: 3/5

The workflow change introduces a license check that will immediately fail for files that are not excluded but lack recognized copyright comment headers.

The skills/** glob matches SKILL.md files in every skill subdirectory and jvm.config. None of these files have an SPDX or Apache copyright comment header (the SKILL.md files rely on a YAML license: field, which the checker does not recognize), and none are in the exclusion list. Any PR that modifies one of those files will fail CI until they are either excluded or given proper headers.

.github/workflows/license-header-check.yml — the exclusion list needs to cover skills/**/SKILL.md and skills/udf-gen-test/templates/scala/.mvn/jvm.config (or those files need license comment headers added).

Important Files Changed

Filename	Overview
.github/workflows/license-header-check.yml	Adds skills/** to included patterns with exclusions for README.md, .gitignore, and docs/**; however, SKILL.md files in each subdirectory and jvm.config lack standard license comment headers and are not excluded, which will cause the check to fail on any PR touching those files.

Pull request overview

Enables the repository’s license-header-check GitHub Actions workflow to include the “skills” content, aligning CI enforcement with Issue #15112’s request to keep skill license/SPDX header years up to date when those files change.

Changes:

• Extend the workflow’s included_file_patterns to cover files under skills/.

Suggested change

	skills/*
	skills/udf-*/**

We want everything, markdown and code, under skills to be checked, but not top-level things like skills/docs/dev or skills/README.md. We do want skills/examples/ and the upcoming skills/test/ covered, but those should already be covered under the existing extension patterns.

[YanxuanLiu]

Only README.md and VERSIONS.md should be excluded, right?

[YanxuanLiu]

Now included all files under skills except skills/docs/** skills/README.md

[rishic3]

More files will be added, e.g. see #15131 which adds pyproject.toml.
