Poetry

The umbrella gem. One line installs the library proper: the engine, the components, and the default icon set. Everything else in the family is opt-in and listed below.

What the umbrella installs

poetry-core is the framework layer: the Rails engine, the component base class, the DSL that gives a component its style axes, options, parts and slots, the Stimulus integration, and the design-token foundation every theme is built on.

poetry-ui is the component library itself: 88 accessible, themeable components exposed as poetry_* helpers, nine complete themes, the model-bound form builder, the vetted blocks, and the agent surface that this site and the MCP tools read.

poetry-lucide is the default icon set: Lucide's icons vendored at a pinned commit and sanitized when vendored, so rendering an icon never parses, sanitizes, or fetches anything.

Install

Add the gem and run the installer. It wires the engine, the Tailwind entry point and the importmap pins, and writes the agent skills into the app. 

gem "poetry"

bundle install
bin/rails generate poetry:install

From there poetry_button, poetry_dialog, poetry_data_table and the rest are available in every view; the installation guide covers themes, charts and upgrades.

The ecosystem gems

Add what you use; nothing here is pulled in by the umbrella. The family releases in lockstep and every gem pins its siblings to its own version, so these resolve to the umbrella's release without version constraints.

  • Charts: nine chart families computed in Ruby and shipped as finished SVG.
  • Agent: the MCP server, the WebMCP runtime, the AG-UI relay and the A2UI catalog and renderer.
  • Extract: a DESIGN.md and deterministic tokens from any public website.
  • Simple Form: the migration bridge for apps already on Simple Form.
gem "poetry"
gem "poetry-charts"        # server-rendered SVG charts
gem "poetry-agent"         # MCP server, WebMCP, AG-UI, A2UI
gem "poetry-extract"       # DESIGN.md + tokens from any public site
gem "poetry-simple_form"   # the Simple Form migration bridge

Where it lives

The code is on GitHub, where the umbrella's README links every sibling repository, and the gems are on RubyGems. The family's version is one number across all of them.
