### Problem/Motivation The **Default information tools** field on the AI Agent form is currently a plain `textarea` — `src/Form/AiAgentForm.php:244`. The AI module 1.4.0 introduced a dedicated form element for picking AI tools — `'#type' => 'ai_tools_library'` (`Drupal\ai\Element\ToolsLibrary`, powered by the `default_tools_editor` library; see `ai/ai.libraries.yml:81`). ### Proposed resolution Replace the `textarea` on `default_information_tools` in `AiAgentForm` with `'#type' => 'ai_tools_library'`. ### Note The current field stores YAML with per-tool parameter values (`AiAgentEntityWrapper.php:965`), while `ai_tools_library` accepts a list of plugin IDs. If those parameter values must be preserved, an upgrade path / data-shape decision is needed; otherwise this is a straightforward swap. --- _Filed with AI assistance (Claude Code)._
