Ask HN: Is there a format for sharing prompts used in OSS

I recall reading about a major OSS project providing the prompts they used to vibe code their plugin(?) and was wondering if someone came up with a spec / format on how best to share the prompts used.

In my case, I'm using Cursor and just prompting to have the agent do one task after another. I want to share the prompts I used to quickly build a new transport for my LogLayer logging library for Typescript (https://loglayer.dev).
