name	version-bumper
description	Bump the Airflow or Python version across all project files. Use when the user wants to update AIRFLOW_VERSION or PYTHON_VERSION.
argument-hint	[airflow|python] <new-version>
disable-model-invocation	false

Bump a version across all relevant files in the whirl project.

Instructions

The user will specify which version to bump (airflow or python) and the new version number.

If the version type or target version is unclear, ask the user before proceeding.

File types to search

The version string appears as a hardcoded literal (not a shell variable reference like ${AIRFLOW_VERSION}) in these file types:

• **/.whirl.env — as AIRFLOW_VERSION=<version> or PYTHON_VERSION=<version>
• **/Dockerfile and **/Dockerfile.* — as ARG AIRFLOW_VERSION=<version> or ARG PYTHON_VERSION=<version>
• **/*.yml — as airflow_version: ["<version>"] or in python_version: [...] lists
• CLAUDE.md — as prose references to the current version

Steps

1. Discover the current version by searching for the literal version pattern across the relevant file types:

   # For AIRFLOW_VERSION
   grep -rn "AIRFLOW_VERSION=[0-9]" --include="*.env" --include="Dockerfile*" .
   grep -rn "airflow_version:" --include="*.yml" .
   grep -rn "AIRFLOW_VERSION" CLAUDE.md
   
   # For PYTHON_VERSION
   grep -rn "PYTHON_VERSION=[0-9]" --include="*.env" --include="Dockerfile*" .
   grep -rn "python_version:" --include="*.yml" .
   

   This reveals the current version and every file that needs updating.

2. Exclude false positives — skip matches where the version is a shell variable reference (e.g. ${AIRFLOW_VERSION}) or a minimum-version guard (MINIMAL_AIRFLOW_VERSION). These must not be changed.

3. Edit each matched file using the Edit tool, replacing the old version string with the new one. Use replace_all: true for files where the string appears multiple times (e.g. Dockerfiles with two ARG lines, CI workflows with multiple matrix blocks).

4. Verify by re-running the discovery grep from step 1 and confirming no occurrences of the old version remain:

   grep -rn "<old-version>" --include="*.env" --include="Dockerfile*" --include="*.yml" .
   grep -n "<old-version>" CLAUDE.md
   

5. Report which files were changed and the new version value in each.

6. Check docker-compose changes against the official Airflow release (Airflow version bumps only):

   Fetch the official docker-compose for the new version:

   curl -Lf 'https://airflow.apache.org/docs/apache-airflow/<NEW_VERSION>/docker-compose.yaml'
   

   Then read each envs/*/docker-compose.yml in this repo and compare the Airflow service definitions (api-server, scheduler, dagprocessor, triggerer) against the official file. Focus on:

   • New or removed environment variables in the x-airflow-common block
   • New or removed volume mounts
   • Changed healthcheck commands or intervals
   • Changed service dependencies (depends_on)
   • Changed ports or commands

   Known intentional differences to ignore — these are whirl-specific and must NOT be "fixed":

   Topic	Official docker-compose	Whirl envs
   Image	apache/airflow:<version>	docker-whirl-airflow:py-${PYTHON_VERSION}-local
   Port	api-server on 8080	api-server on 5000 (with -p 5000 command arg)
   Executor	CeleryExecutor with worker + Redis	No executor set (uses LocalExecutor via .whirl.env)
   Env vars (official only)	AIRFLOW__CORE__EXECUTOR, AIRFLOW__DATABASE__SQL_ALCHEMY_CONN, AIRFLOW__CELERY__*, AIRFLOW__CORE__FERNET_KEY, AIRFLOW__CORE__DAGS_ARE_PAUSED_AT_CREATION, AIRFLOW__CORE__LOAD_EXAMPLES, AIRFLOW_CONFIG, _PIP_ADDITIONAL_REQUIREMENTS	Sourced from .whirl.env via env_file
   Env vars (whirl only)	—	WHIRL_SETUP_FOLDER, AIRFLOW__FAB__AUTH_BACKENDS, AIRFLOW__API_AUTH__JWT_SECRET
   Volume mounts (official only)	logs/, config/, directories
