A set of coding-agent instructions and tools for OpenMetadata, a platform for finding, monitoring, and governing data. It guides planning, test-driven development (writing tests before code), reviews, debugging, and connector work across Java, Python, and TypeScript.

Use it to plan OpenMetadata changes, write tests first, review Java, Python, or TypeScript code, debug issues, enforce 90% test coverage, and develop connectors.

It gives the agent a consistent development process and checks code quality during changes. It also helps keep tests and generated files from being overlooked.

Security

Grade A, and why

skills 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 yesterday.

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 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.
