## [AI Stack Registry and its model-update skill](https://justj.dev/notes/2026-10-26)

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](https://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](https://aistackregistry.com/skill/SKILL.md), with setup steps on the [setup page](https://aistackregistry.com/use/).
