AI agents
An agent skill for Claude Code, Codex, Cursor, Antigravity, Gemini CLI and Copilot: the rules for writing glass, and every page of this site, installed with one command.
g1455 ships an agent skill: a SKILL.md that tells a coding agent how to write glass that
works the first time (one host above the navigator, what the app declares, what costs a capture, which widget fits),
with every page of this site beside it as a reference file. The agent loads it on its own when a project uses g1455 or
you ask for liquid glass, and reads a component's page before it writes one.
Any agent
npx skills add PlugFox/g1455
The installer (skills.sh) asks which agents to install for and puts the skill where each one looks.
-a claude-code -a codex picks agents without asking, -g installs for your user instead of the project, -y skips
the questions. npx skills update brings it up to date.
The same works from this site's address, which publishes the skill at
/.well-known/agent-skills/index.json:
npx skills add https://g1455.plugfox.dev
Claude Code
The repository is a plugin marketplace with the skill as its one plugin. In Claude Code:
/plugin marketplace add PlugFox/g1455
/plugin install g1455@g1455
/plugin marketplace update g1455 fetches a newer one.
Without Node
The skill is one archive. Unpack it where your agent looks for skills:
mkdir -p .agents/skills/g1455
curl -fsSL https://g1455.plugfox.dev/.well-known/agent-skills/g1455.tar.gz | tar -xz -C .agents/skills/g1455
| Agent | In the project | For your user |
|---|---|---|
| Claude Code | .claude/skills/g1455 |
~/.claude/skills/g1455 |
| Codex, Cursor, Antigravity, Gemini CLI, GitHub Copilot | .agents/skills/g1455 |
~/.agents/skills/g1455 |
Commit the project's copy and everyone working on the app gets it.
Without installing
Tell the agent to read the skill from the site, and it follows the links it needs:
Read https://g1455.plugfox.dev/SKILL.md and follow it.
Every page of the site is also markdown at its address plus .md, such as
/components/slider.md. llms.txt
lists them all, and llms-full.txt is every page in one file.
Note
The skill describes the package's current version, and the API is 0.x. Update the skill when you update the package; it tells the agent to check the changelog when the versions differ.
