Every push and pull request triggers validation checks:
- ✅ YAML frontmatter structure and field validation
- ✅ Semantic versioning compliance
- ✅ Security scanning for hardcoded secrets
- ✅ Python and JavaScript syntax validation
- ✅ Documentation completeness
- ✅ File reference integrity
View workflow: .github/workflows/validate.yml
When you push a version tag, the pipeline automatically:
- Validates the skill structure
- Updates version in Skill.md
- Packages into a ZIP file
- Generates release notes
- Creates a GitHub release
- Uploads the package as an artifact
Create a release:
git tag v1.0.0 -m "Release version 1.0.0"
git push origin v1.0.0View workflow: .github/workflows/release.yml
# Validate skill structure
python .github/scripts/validate-skill.py skill-creator
# Check Python scripts
python -m py_compile weaver-create/templates/*.py
# Check JavaScript scripts
node --check weaver-create/templates/*.js
# Package locally
./scripts/package-skill.sh- Update the version in
weaver-create/Skill.md - Update the version history in
weaver-create/README.md - Commit your changes
- Create and push a tag:
git tag v1.1.0 -m "Release version 1.1.0" git push origin v1.1.0 - GitHub Actions will automatically create the release
We follow Semantic Versioning:
- MAJOR: Breaking changes to skill structure or behavior
- MINOR: New features, templates, or capabilities
- PATCH: Bug fixes, documentation updates, typos
Using the Skill Weaver teaches you:
- ✅ How to structure Custom Skills properly
- ✅ YAML frontmatter requirements and best practices
- ✅ Progressive disclosure for efficient loading
- ✅ Script integration with Python and JavaScript
- ✅ Security considerations for skills
- ✅ Testing and validation strategies
- ✅ Packaging and distribution methods
