Demonstrate the search functionality on RubyDoc.info by searching for the 'rails' gem. Once the search results are displayed, identify the most recent version of 'rails' listed and click on its link to navigate to its documentation page. On the 'rails' documentation page, find and state the first sentence of the 'README' or 'Overview' section, if present. If the main search bar does not work, identify and use an alternative search method or navigation path to find the 'rails' gem.
Navigate to 'https://rubydoc.info/'. Locate the primary search input field and attempt to search for 'rails'. If the primary search input does not yield results or a clear submission mechanism, identify and use an alternative search method (e.g., a dedicated search page, or direct navigation to the 'R' section and then using pagination links to quickly jump through the list). Once on a search results page or the alphabetical listing where 'rails' is visible, identify the link for the most recent version of the 'rails' gem. Click on the link for the most recent version of 'rails'. On the 'rails' documentation page, locate and extract the first sentence of the 'README' or 'Overview' section.
The agent successfully navigates to a search results page or an alphabetical listing where 'rails' is found. The agent identifies and clicks on the link for the most recent version of the 'rails' gem (e.g., 'rails 8.0.2'). The agent successfully navigates to the documentation page for the selected 'rails' version. The agent states the first sentence of the 'README' or 'Overview' section from the 'rails' documentation page.
