Use CircleCI dynamic configuration to generate and continue a pipeline from a setup workflow

Steps

1. Add setup: true at the top level of .circleci/config.yml so it's treated as a minimal setup configuration; dynamic config must also be enabled on the project (default for projects created after Dec 1, 2023).
2. In the setup workflow, run a job that determines or generates the downstream configuration — for example the path-filtering orb to select jobs based on changed paths, or a custom script that writes a generated YAML file.
3. Include the circleci/continuation orb in the setup config and call its continue command at the end of the setup job, passing the generated config file and any parameters to forward.
4. The continuation orb calls the continuation API to hand off to the generated configuration, which CircleCI then runs as the pipeline's real workflows.
5. Verify in the CircleCI UI that the pipeline shows the setup workflow followed by the dynamically continued workflows, with any forwarded parameters visible in the continued jobs.
