airflow-dag-git#

Purpose#

Operate Airflow DAG files through GitHub PR workflow only.

Available tools#

• airflow_dag_git_read_file
• airflow_dag_git_open_pr

Guardrails#

• Use allowlisted owner, repo, and DAG paths only.
• Target must be a single .py file.
• No path traversal, absolute paths, delete, rename, or multi-file operations.
• No CI workflow changes.
• open_pr requires DAG-like content ( DAG( or @dag) and rejects dangerous patterns.

Expected workflow#

1. Read existing DAG with airflow_dag_git_read_file.
2. Prepare updated DAG content.
3. Submit update through airflow_dag_git_open_pr.
4. Human reviews PR and decides merge.

Rollback#

• Close PR if not merged.
• Delete created branch.
• Revert merge commit if already merged.
