Show HN: Prom.dev – Prompts that simulate Hacker News (and a tool to share them) (prom.dev)

Prom.dev is a compact, shareable collection of curated prompts and a small toolset designed to simulate Hacker News behaviors and other targeted tasks for LLMs. The creator publishes go-to prompts — e.g., roleplaying an HN moderator to moderate a thread, generating Product Requirements Documents (PRDs), converting product specs into LLM-friendly development checklists for LLM+human pair programming, producing biting “Show HN” comments, and even niche prompts like laundry Q&A. The site emphasizes reproducibility and shareability: users can pick, tweak, and distribute prompts that encapsulate useful workflows and persona-driven outputs. For the AI/ML community this matters because well-crafted, task-specific prompts are increasingly central to prompt engineering, model evaluation, and synthetic-data generation. Prom.dev provides reusable templates for common engineering and moderation workflows (PRD-to-checklist conversion, role-based moderation), which can speed prototyping, standardize benchmarking, and help design human+LLM collaboration patterns. It also surfaces risks and opportunities: prompts that intentionally provoke scathing comments can be useful for adversarial testing and moderation research but raise content-safety concerns. In short, Prom.dev is a pragmatic prompt library and sharing tool that supports reproducible prompt engineering, workflow automation, and evaluation scenarios—useful for developers, researchers, and ops teams experimenting with LLM-driven processes.
