This VS Code extension provides IntelliSense and autocomplete for WordPress hooks, actions, and filters.

• Autocomplete for action and filter names
  • Supports all actions and filters up to WordPress 6.8
• Autocomplete for action and filter callback functions
  • Supports functions, class methods, closures, arrow functions, and more
  • The parameter types, return type, and a docblock are included where appropriate
  • Various options can be controlled in the settings for the extension
• Hover information on action and filter names
  • Includes a useful link to the developer.wordpress.org documentation site

Start typing the name of a WordPress action or filter within add_action() or add_filter() and you'll get an autocomplete list of all matching actions or filters, plus information about the parameters and usage:

Autocomplete is also provided for the callback function. It's contextually aware and provides options for a function, a class method, a closure, an arrow function, and WordPress' built-in utility functions:

An autocompleted closure callback looks like this:

Hover information for an action or filter name looks like this:

• add_action()
• add_filter()
• remove_action()
• remove_filter()
• has_action()
• has_filter()
• doing_action()
• doing_filter()
• did_action()
• did_filter()

Place your cursor within the first parameter of one of the supported functions, eg add_action() or add_filter(), and hit ctrl+space. This works with any autocomplete provider, not only this extension.

Yes, open the preferences for VS Code and go to the Extensions -> Hooks IntelliSense for WordPress section.

They're generated directly from the WordPress core software and updated in time for each new release. They're bundled with this extension so there's no requirement for your project to include WordPress if you don't want to, and the extension doesn't scan the files in your project looking for actions and filters.
