title: How early can I get access to the requested post in a WordPress plugin?
body: <p>What is the earliest WordPress action/hook where I can get access to information about the post requested?</p>
  
  <p>Based on a custom field in the post, I need to disable several plugins.  I can do this in the <code>options_actions_plugins</code> filter, but that fires <em>early</em> (before even <code>wp</code>).</p>
  
  <p>I need to find an action that fires before <code>options_actions_plugins</code> in which I can get access to the requested post data, and figure out if I should disable plugins or not.</p>
  
  <p>What action am I looking for?</p>
