The CircleCI Pipeline Manager skill handles end-to-end CI/CD pipeline configuration and management through the CircleCI v2 API and .circleci/config.yml authoring. It creates pipeline configurations using CircleCI concepts including executors (docker, machine, macos), orbs (circleci/node@5, circleci/aws-cli@4, circleci/docker@2), commands, and jobs with proper workflow orchestration using requires and filters. The skill triggers pipelines via POST /api/v2/project/{project-slug}/pipeline with pipeline parameters, monitors workflow status through GET /api/v2/workflow/{id}, and retrieves job artifacts. It supports advanced features including dynamic configuration with setup: true workflows and the continuation orb, workspace and cache management with persist_to_workspace and save_cache/restore_cache steps, and parallelism with circleci tests split. The manager handles context management for shared secrets, scheduled pipeline triggers via the API, and config validation using the circleci config validate command.
