Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00080 | $0.03019 |
| Opus 5 | $0.00040 | $0.01510 |
| Sonnet 5 | $0.00016 | $0.00604 |
| Haiku 4.5 | $0.00008 | $0.00302 |
Grade A, and why
gcp-managed-airflow-migrations scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
98% identical to managed-airflow-migrations — 21 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 333 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Managed Service for Apache Airflow (formerly Cloud Composer) Migration Guide
This skill guides you through the process of adjusting Airflow DAGs from an existing Managed Service for Apache Airflow (formerly Cloud Composer) environment (or available locally) to make them compatible with Airflow 2.11.1 (MSAA Gen 2 or 3) or Airflow 3 (MSAA Gen 3).
Phase 1: Discovery & Download
Before making any changes, download the existing DAG files if explicitly requested. Inspect the source environment to confirm source version only if explicitly requested. For detailed instructions about environment inspection and downloading files check references/environment-inspection.md.
Phase 2: Target Version & Dependency Mapping
2.1 Airflow 2.11.1+ Dependency Mapping
If migrating to Airflow 2.11.1 (MSAA Gen 2) or Airflow 3, use the list below to trace the version progression of key dependencies. The list covers changes needed to get to Airflow 2.11.1. Take them into account when migrating from Airflow 2 (earlier than 2.11.1) to Airflow 3.

10.26.0 - SSH Provider:

What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

gcp-managed-airflow-migrations is a skill published in the GitHub repository gemini-cli-extensions/data-agent-kit-starter-pack (180 stars, last pushed today), licensed Apache-2.0. It adds 80 tokens to every session and 3,019 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. It is 98% identical to managed-airflow-migrations, differing in 21 lines, and is treated as a copy.
