AI Stack Registry and its model-update skill

AI Stack Registry is a public catalog of current AI model ids, token limits and provider settings, served as one JSON file at aistackregistry.com. Its update-ai-models skill lets a coding agent fetch that catalog once and reuse it for every repo in an update. The agent shows a plan before editing, changes only model and provider fields, and reports what it skipped. The skill never calls a model provider, so the update needs no API keys. The skill is at aistackregistry.com/skill/SKILL.md, with setup steps on the setup page.
