Function calls have silent dependencies

The content type AI Agent has:

  /**
   * {@inheritDoc}
   */
  public function isAvailable() {
    // Check if node module is installed.
    return $this->agentHelper->isModuleEnabled('node');
  }

so I'm not entirely sure how you got it to be available on a site without node enabled?

Can you provide steps to recreate?

Steps given in the initial report.

The isAvailable method only appears to be called in ai_agents_extra's MCP plugin, and the ai_content_suggestions settings form.

That probably should be checked in other places, but is more suitable for "run time" checks, rather than dependency checks. For example, if a function call tried to inject a dependency from a module not enabled, you wouldn't be able to instantiate the plugin to call isAvailable.

Are you saying you want some kind of system that works without instantiating the plugin?

Ah, just realised this is a duplicate of a ticket Marcus has already fixed - 📌 Add module dependencies to tools Active .

We are doing some issue management housekeeping and adding/removing components.

We are removing the "Code" component and want people to categorize issues with the best module/submodule component.

Moving this issue to "AI Core module".

See 📌 Update AI module project components Active for more details.
