• src/index.js:1624-1632 (schema)

  Input schema defining parameters for the github_actions_create_ci tool: project_type (required), include_docker, include_sonar, sonar_org, github_owner
  project_type: { type: "string", description: "Project type: java-maven, java-gradle, nodejs, python, golang" }, include_docker: { type: "boolean", description: "Include Docker build and GHCR push", default: true }, include_sonar: { type: "boolean", description: "Include SonarCloud analysis", default: false }, sonar_org: { type: "string", description: "SonarCloud organization (if include_sonar)", default: "" }, github_owner: { type: "string", description: "GitHub owner for GHCR push" } },
• src/index.js:1633-1822 (handler)

  Handler implementation that generates and returns a GitHub Actions CI/CD workflow YAML based on the project type, with optional Docker build/push to GHCR and SonarCloud integration.
