Agent setup

Fable UI skill for safe registry installation and host integration.

The Fable UI agent skill lives at .agents/skills/fable-ui. It helps an agent inspect a host app, select the smallest complete Fable UI item set, and follow the registry and integration boundaries.

This is documentation for a skill, not an MCP server. No MCP endpoint, tool, credential bridge, or automatic host mutation is implied by this page.

Install from the repository

Install the named skill into the current project with the Skills CLI:

pnpm dlx skills add shobky/fable-ui --skill fable-ui

The command is intentionally project-scoped by default. Review the CLI's target-agent prompt and the resulting files before committing them. For a global installation or a specific agent, use the Skills CLI options appropriate to that agent.

Download package

Download the deterministic package here:

Download fable-ui.skill

Use the download only with an agent product that supports .skill packages. The package and repository skill contain the same guidance; neither installs a registry item, configures a model provider, or grants access to host data by itself.

Intended workflow

The skill guides an agent to:

  1. Inspect the host aliases, existing target files, package manager, and shadcn setup.
  2. Use the hosted Fable URL for each requested registry item.
  3. Dry-run and review collisions before any install; never default to overwrite.
  4. Record pnpm build-script decisions and validate the host after installation.
  5. Add only the required tool registration, trusted renderer mapping, callbacks, and data-provider loop.
