Debug Bar Rewrite Rules adds information about Rewrite Rules (changed via filters) to a new panel in the Debug Bar. This plugin is an extension for <a href="https://wordpress.org/extend/plugins/debug-bar/" rel="ugc">Debug Bar</a>, but it is also can work in standalone mode (as admin tools page). Note: this plugin not able to track <code>add_rewrite_rule</code> function calls, for a reason this function is untraceable.
Once installed, you will have access to the following information:
<ul>
<li>Number of existing rewrite rules</li>
<li>List of rewrite rules</li>
<li>List of available filter hooks that can affect rewrite rules.</li>
<li>List of filters that affects rewrite rules.</li>
<li>Ability to search in rules with highlighting matches.</li>
<li>Ability to test url and see what rules can be applied to it.</li>
<li>Ability to flush rules directly from debug bar panel/tools page.</li>
</ul>
