dag-factory SKILL.md skillA
dag-factory from vanducng/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add vanducng/skills/dag-factory@v0.1.0Pins v0.1.0 in mdr.lock. Pin the fingerprint instead.

Author Airflow DAGs from dag-factory YAML. Use when creating or editing YAML DAG configs, loaders, callbacks, custom operators in YAML, dynamic mapping, datasets, or validating dag-factory files. Covers both map-style tasks (task_id as YAML key) used by in-repo plugins and the PyPI dag-factory v1 list format. Not for remote run/log inspection (vd:astro-airflow) or local astro dev lifecycle (vd:managing-astro-local-env).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# dag-factory
Declarative Airflow DAGs from YAML. Detect the repo's dialect **before** writing YAML. Official Astronomer skill targets PyPI `dag-factory` v1+ (list-format `tasks`). Many production repos still use a vendored plugin and **map-format** `tasks` keyed by `task_id`. Mixing the two breaks parse.
## 1. Detect dialect
```bash
rg -n "load_yaml_dags|from dagfactory|from plugins.dagfactory" --glob '*.py' dags plugins | head
rg -n "^ tasks:" -g '*.yaml' -g '*.yml' -A 6 | head -40
```
| Signal | Dialect |
|---|---|
| `from plugins.dagfactory import load_yaml_dags` (or similar in-repo plugin) | **map** - `tasks.<task_id>.operator` |
| `from dagfactory import load_yaml_dags` + `dag-factory>=1` in deps | **list** - `tasks: [{task_id, operator}]` |
| `tasks:` then a nested key that is a task id, not `- task_id:` | **map** |
| `tasks:` then `- task_id:` | **list** |
Match neighboring YAML in the same folder. Do not "modernize" map-format files to list-format unless the user asks and the loader is PyPI v1+.
Keep `from airflow import DAG` in every loader module even if it looks unused. The DAG processor requires it.
## 2. Loader
Map-style in-repo plugin (typical):

How to install
mdr add vanducng/skills/dag-factory@sha256:231c9b845c4bd857The line at the top of this page pins the label v0.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
