What problem does it solve? Preparing an Ansible collection release on a stable branch involves many error-prone manual steps: creating a prep branch, bumping galaxy.yml, writing a release summary fragment, and running antsibull-changelog correctly. This Skill automates that sequence and fixes known antsibull-changelog output bugs. ## Core Features & Use Cases - Automated release branch preparation: Creates a prep_vX.Y.Z branch, updates the galaxy.yml version, and validates that the new version is higher than the current one. - Changelog generation: Auto-generates a properly formatted release summary fragment and runs antsibull-changelog to produce CHANGELOG.rst and changelog.yaml, with optional custom release dates. - Post-generation validation: Detects and fixes common antsibull-changelog bugs such as YAML indentation errors, overlong release_summary lines, and stray .plugin-cache.yaml files. - Use Case: After analyzing pending changes on stable-1 of the amazon.aws collection, run this Skill to create prep_v1.0.1, bump the version, and generate a lint-clean changelog ready for a release PR. ## Quick Start Prepare release version 1.0.1 from the stable-1 branch of this Ansible collection and generate the changelog.
