From the source SKILL.md

A maioria das ferramentas de SDD é spec-first: a especificação gera código, o código evolui, e a especificação vira mentira. Esta é spec-anchored: a especificação é auditada mecanicamente contra o código, o tempo todo. Você não confia que o agente obedeceu — a máquina prova, via exit code.

What this skill does

onp-spec-driven is a community-contributed Claude Code skill in the engineering-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/onp-spec-driven-antigravity/ and loads when your prompt matches the skill's trigger.

Who uses this skill

The onp-spec-driven Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 213,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

Is this skill free to install?
Yes. ClaudSkills is an open registry — every skill keeps its source repository's license, and manual install via copy is free. ClaudSkills Pro ($9/mo, $79/yr, or $149 one-time) adds one-click install via the desktop app and a multi-signal Quality Score.
When should I use the onp-spec-driven skill?
Use onp-spec-driven when your Claude Code task falls under the Engineering category — specifically in the engineering misc area. Claude Code auto-discovers installed skills and invokes the right one based on the task description, so you can also ask Claude directly (e.g. "use onp-spec-driven" or describe the task and let Claude pick). Browse related skills at /category/engineering/.
What is a Claude Code skill and how does the onp-spec-driven skill fit in?
A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. onp-spec-driven is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Engineering category.
