Class Method Details

.for(data) ⇒ BaseDecorator

Factory returning the per-tool decorator for the given data hash.

Parameters:

  • data (Hash) —

    structured event data with string keys (“role”, “tool”, “content”, etc.)

Returns:

  decorator_for(tool).new(data)
end

Instance Method Details

#color ⇒ String

Unified color for all tool call headers. Keeps tool invocations visually distinct from conversation messages (user/assistant/thought).

Returns:

  • (String)

#icon ⇒ String

Icon for this tool type. Subclasses override with tool-specific icons.

Returns:

  • (String)

end

#render(tui) ⇒ Array<RatatuiRuby::Widgets::Line>

Renders the event, dispatching by role to the appropriate method.

Parameters:

  • tui (RatatuiRuby) —

    TUI rendering API

Returns:

  • (Array<RatatuiRuby::Widgets::Line>)

def render(tui)
  case data["role"].to_s

  when "tool_response" then render_response(tui)
  when "think" then render_think(tui)
  end
end

#render_call(tui) ⇒ Array<RatatuiRuby::Widgets::Line>

Generic tool call rendering — icon, tool name, and indented input. Subclasses override for tool-specific presentation.

Parameters:

  • tui (RatatuiRuby) —

    TUI rendering API

Returns:

  • (Array<RatatuiRuby::Widgets::Line>)

def render_call(tui)
  style = tui.style(fg: color)
  header = build_call_header
  lines = [tui.line(spans: [tui.span(content: header, style: style)])]
  data["input"].to_s.split("\n", -1).each do |line|
    lines << tui.line(spans: [tui.span(content: preserve_indentation("  #{line}"), style: style)])
  end
  lines
end

#render_response(tui) ⇒ Array<RatatuiRuby::Widgets::Line>

Generic tool response rendering — success/failure indicator and content. Token counts get their own color-coded span so expensive responses visually jump out in debug mode. Subclasses override for tool-specific presentation.

Parameters:

  • tui (RatatuiRuby) —

    TUI rendering API

Returns:

  • (Array<RatatuiRuby::Widgets::Line>)

#render_think(tui) ⇒ Array<RatatuiRuby::Widgets::Line>

Think rendering — delegated to ThinkDecorator, but base provides a fallback that renders as a generic tool call.

Parameters:

  • tui (RatatuiRuby) —

    TUI rendering API

Returns:

  • (Array<RatatuiRuby::Widgets::Line>)
