Perhaps the most important file in your plugin readme.txt gets parsed in order to generate the public listing of your plugin
Attributes that need to be fixed:
  • Plugin Name: "Plugin Name" should be replaced with the name of your plugin on the first line ( === redirection === )
The official readme.txt is a good inspiration

redirection/redirection.php Passed 13 tests

The main file in "Redirection" v. 5.3.10 serves as a complement to information provided in readme.txt and as the entry point to the plugin
