Search for Ruby gems related to 'redis' and show me the top results.

I've searched RubyGems.org for 'redis'. The most relevant gems are 'redis' (the official client), 'redis-namespace', and 'redis-objects'. Would you like the full metadata for the main 'redis' gem?

What is the latest version of the 'rails' gem and when was it released?

Using `get_latest_gem_version`, I found that the latest version of 'rails' is 7.1.3.2. It was released on February 21, 2024. Do you want to see the download statistics for this version?

Show me the download count for 'sidekiq' version 7.2.0.

I've retrieved the stats using `get_gem_downloads`. For 'sidekiq' version 7.2.0, there have been approximately 1.2 million downloads. The total downloads for all versions of Sidekiq exceed 150 million.

Yes! Use the `get_reverse_dependencies` tool with the gem name. It will return a list of all gems on RubyGems.org that list that gem as a dependency.
