Description
Hi HN, I built VAEN (an open source CLI) because I kept running into a boring problem with AI coding-agent workflows: the setup becomes useful, but then it is hard to move.A good, useful agentic harness consists of more than just instructions: skills, mcp servers and more. There should be a better way to share those than just .MD files, and that is why I created VAEN.What works: create a yaml, run the CLI commands as per the repo, and get a .agent file that you can share and extract. Think of how awesome it could be if anyone could use a very useful agentic harness, and share it with one CLI command.

Could you build this?
Yes VAEN is a command-line interface tool to package and share AI configurations, prompts, and MCP server manifests into reproducible archives, which is standard CLI file manipulation easily written with an LLM.

Same idea, different domain
Nobody's really built a agent / copilot tool for Agriculture yet.
