Show HN: QUALITY.md – open format/specification, agent skill, and CLI

- QUALITY.md is an open-source spec and CLI tool that defines a Markdown format for tracking software quality across dimensions like performance, accessibility, security, and maintainability. It is designed for both humans and AI agents to read and act on. - It sits at the intersection of "quality-as-code" (formalizing quality checks the way infrastructure-as-code formalized deployments) and "agentic AI" (LLM agents that autonomously read specs and execute tasks). The creator frames it as useful for "loop engineering" — iterative AI cycles of build, measure, and refine. - The project aims to shift from a reactive "break-fix" mindset (find bugs, patch them) to "proactive care" — defining quality criteria upfront so issues are prevented. - "Show HN" is a Hacker News category where developers present new projects. The audience would recognize QUALITY.md as aspiring to become a conventional repo file like CODEOWNERS or CONTRIBUTING.md.
