Teaches an agent to find skills and rules in this catalog and install them into a project or globally, with checksum verification.
Install through your agent — tell it:
Read https://ufo-tech.space/ai/install.md and install the ufo-catalog skill from the UFO Tech catalog.

The agent reads this variant by its link, without installing it: https://ufo-tech.space/ai/files/skill/ufo-catalog/universal/SKILL.md
About
The skill to start with: once it is installed, just tell your agent "find a skill for … in the UFO Tech catalog" or "install the json-rpc-bundle rules into this project".
What it does
- Reads the catalog index
https://ufo-tech.space/ai/catalog.json— titles, descriptions, tags, files and checksums. - Searches it for your request and shows up to five matches with links to their pages.
- Asks where to install: into the project (the whole team gets it once committed) or globally (all your projects).
- Shows which files it will write and where, downloads them and checks their SHA-256 against the index.
- For rules, adds a reference line to
CLAUDE.mdorAGENTS.mdwhen the agent needs one.
The agent never runs downloaded scripts and never changes global settings (hooks, settings.json) on its own — it only shows you such steps.
How to install
The easiest way — give any agent the link and ask it to follow it:
Read https://ufo-tech.space/ai/install.md and install the ufo-catalog skill for yourself globally.
By hand — commands for Claude Code and Codex are below on this page, in the "Installation" block.
Updating and removing
Tell the agent "update my skills from the UFO Tech catalog" — it compares checksums and downloads only changed files. To remove: "remove the … skill from the UFO Tech catalog".
