Neckbeard scaffolds cost-checked cloud infra for coding agents

Neckbeard is an open-source Claude Code plugin that keeps agents from inventing infrastructure. Humans maintain a versioned catalog of OpenTofu modules for a fixed shape (container image, HTTP, worker and cron processes, Postgres, object storage). The agent profiles the app, asks what code cannot answer, then plans and scaffolds from that catalog, with Infracost estimates before anything is created. The README quotes about $77 a month for the smallest Cloud Run reference app across three environments, versus hundreds for Kubernetes, and it refuses to overwrite files you have edited. On Hacker News (75 points, 56 comments), there is no consensus. Four commenters questioned the need for it: two said they would rather write their own Terraform or OpenTofu, one said you can just ask the agent, and one called it a bunch of Terraform modules. The author replied that the point is opinionated modules the agent does not have on its own, and agreed it targets apps moving off Vercel or Supabase onto containers or serverless. Two said a cheap Hetzner server would cost less, and the author said Hetzner support is next. One commenter worried an LLM could make cloud spend skyrocket; the author replied that the tool does not let the LLM do that. One disliked the AI-sounding README. A side thread joked about other hair-named plugins, and a commenter who said they created ponytail, the plugin that inspired it, welcomed it. Sorted take: useful if you are moving a Vercel or Supabase app onto AWS, GCP or Azure and want a reviewable bill before apply. Skip it if you already run mature infrastructure as code.
