add-adapter-method

A command for adding a new method to the two Airflow API adapters used by the project. Adapters are separate code paths that hide differences between Airflow 2 and Airflow 3.

In plain words
What is it for?
Use it when an integration needs a new Airflow operation available through both the version 2 and version 3 APIs.
Why use it?
It prevents support for one Airflow version from being added while the other is forgotten, and reminds you to normalize different API responses.

Made for: Claude Code.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

add-adapter-method 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 2d 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.

What it actually says

Add method $ARGUMENTS to both V2 and V3 adapters.

Steps

  1. Add abstract method to adapters/base.py:
@abstractmethod
def method_name(self, param: str) -> dict[str, Any]:
    pass
  1. Implement in adapters/airflow_v2.py:
def method_name(self, param: str) -> dict[str, Any]:
    return self._call(f"endpoint/{param}")
  1. Implement in adapters/airflow_v3.py:
def method_name(self, param: str) -> dict[str, Any]:
    return self._call(f"endpoint/{param}")

Version Differences

Feature Airflow 2.x Airflow 3.x
API path /api/v1 /api/v2
Assets datasets assets
DAG runs execution_date logical_date

Normalize V2 responses to match V3 field names when they differ.

Changes

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.
