Over the past few weeks I've grown tired of these super, all in one, agentic AI Skill plugins, MCP servers and whatnot that promise you the world. Of course, there is a world of vibes that survives off that, but there is also a world of more constraints and responsibilities.

Hence I built Yamlet: A CLI tool with accompanying Claude Code skillset, that merges both deterministic checks with human like interface to help you define requirements - including acceptance criteria, which are then promptly used to generate adequate Gherking *.feature test files. The details are stored in a minimized fashion as *.yamlet.yaml files, which allow quick and easy review - without the usual multi page slop specs.

- And that's it. Everything else, depends entirely on the system you're working on. I stopped here because for me, this can not only be used in a system of pure agentic coding, but also with a normal dev team.
