skills CLI

Full specification: AI skill reference on objectstack.ai. This page is the summary: where ObjectOS uses it, and a few examples.

The skills CLI (by vercel-labs/skills) installs domain-scoped instructions into an AI coding agent. The ObjectStack skills teach Claude Code, Cursor, Copilot, Codex and the rest to write the metadata ObjectOS runs — objects, views, flows, permissions, queries, CEL — against the real schemas, so what the agent writes compiles.

Where ObjectOS uses it

• Hand-authoring an app in your IDE. The in-browser AI Builder writes metadata for you in ObjectOS; the skills give your own coding agent the same vocabulary when you work in a repository instead. See Build → IDE Skills.
• Keeping an agent current. The skills live in the objectstack repository beside the schemas they describe, so re-installing after an upgrade brings the agent up to date.

Examples

Install the skills into the current project. The CLI detects which agents the project uses and writes each one's native format (.claude/skills/, .cursor/rules/, AGENTS.md, …):

npx skills add objectstack-ai/objectstack/skills

Pin a version for reproducible CI:

npx skills add https://github.com/objectstack-ai/objectstack/tree/<commit-sha>/skills

See and manage what is installed:

npx skills detect                  # show which agents the CLI will write to
npx skills list                    # list installed skills
npx skills remove <name>           # remove a skill

Commit the output. Skills are markdown your whole team — CI agents included — should share, and the paths the CLI writes are ones you would check in anyway.
