What problem does it solve? Releasing a multi-package Python SDK involves error-prone manual steps: version bumps across packages, TestPyPI validation, CI pipeline configuration, and Git tagging. This Skill encodes the complete release runbook so nothing is skipped and releases happen in correct dependency order. ## Core Features & Use Cases - PyPI Release Runbook: Step-by-step procedures for version consistency checks, wheel building, TestPyPI validation, production publishing, and rollback via yanking. - CI/CD Pipeline Patterns: GitHub Actions templates for test matrices, multi-platform wheel builds (including maturin/Rust), tag-triggered publishing with OIDC trusted publishers, and documentation deployment. - Git & Project Management Workflows: Branching strategies, conventional commits, PR workflows, GitHub issue templates, and todo-to-GitHub synchronization rules. - Use Case: When releasing kailash v0.9.26, follow the runbook to bump versions in all four packages, push a tag, and let CI build wheels, publish to TestPyPI then PyPI, and create the GitHub Release automatically. ## Quick Start Ask the assistant to walk you through releasing a new version of your Python package to PyPI using the deployment-git skill.
