"context": "Tests whether the agent follows the rails-engine-release skill when preparing a Rails engine gem for release: updating CHANGELOG and version constant before anything else, applying semantic versioning correctly, following the release order, and producing all required output artifacts.",

"checklist": [
{
"name": "Version constant updated",
"description": "The version file (lib/<engine>/version.rb or equivalent) has its VERSION constant updated to the new version number",

"description": "The agent mentions running or confirms that the full test suite passes as a step in the release process",
