airflow-unfactor: Instructions file for Claude Code

CLAUDE.md

airflow-unfactor CLAUDE.md is an instructions file for Claude Code from gabcoyne/airflow-unfactor. It costs 1,029 tokens per session, scanned A, original, MIT.

Project instructions for airflow-unfactor, an MCP server that helps convert Apache Airflow workflows, called DAGs, into Prefect workflows, called flows. It supplies source code and translation guidance for a language model to generate the new code.

In plain words
What is it for?
Use them when developing or operating airflow-unfactor, especially its source-reading, concept-lookup, and Airflow-to-Prefect conversion process.
Why use it?
Converting workflow code with fixed templates can miss project-specific details. These instructions describe the server’s build-time knowledge and runtime steps for helping the model perform the conversion.

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

airflow-unfactor CLAUDE.md 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 8d 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.

Project Overview

An MCP server for LLM-assisted conversion of Apache Airflow DAGs to Prefect flows. The LLM reads raw DAG source code directly and generates complete Prefect flows using pre-compiled translation knowledge.

Key Insight: Deterministic code templating is brittle for DAG conversion. Instead, we provide raw source code + translation knowledge compiled from live sources, and the LLM generates the code.

We provide raw code, translation knowledge, and validation. The LLM generates the code.

MCP Tools

Tool Purpose
read_dag Read a DAG file, return raw source + metadata (path, size, line count)
lookup_concept Query Airflow→Prefect translation knowledge (operators, patterns, connections)
search_prefect_docs Search live Prefect documentation via Prefect MCP server
validate Return both sources + syntax check for LLM comparison
scaffold Generate Prefect project directory structure (not code)

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.
