+## Specialized agents
+
+**Specialized agents** (referred to as custom agents in platforms like
+Antigravity) are AI assistants configured with dedicated system prompts,
+curated tool sets, and focused skill subsets.
+
+While agent skills guide general-purpose assistants during active coding,
+specialized agents run in isolated contexts to perform deep, single-purpose
+workflows without cluttering your primary conversation history.
+
+### Flutter Accessibility agent
+
+The **Flutter Accessibility (`a11y`) agent** is an official specialized agent
+designed to audit Flutter widget trees and recommend accessibility
+improvements. The accessibility agent is currently available in
+[Google Antigravity](https://antigravity.google).
+
+Key capabilities of the accessibility agent include:
+
+* **Semantic label inspection**: identifies interactive widgets (such as
+  `IconButton` or `InkWell`) that lack descriptive semantic labels.
+* **Touch target validation**: flags interactive elements with hit test
+  areas smaller than the recommended 48x48 logical pixels.
+* **Contrast and visual checks**: highlights potential contrast ratio issues
+  and missing focus indicators.
+* **Automated code fixes**: generates idiomatic Flutter fixes (such as
+  wrapping widgets in `Semantics` or adjusting tap bounds) that you can review
+  and accept.
+
+### Using the accessibility agent in Antigravity
+
+After installing the official [Dart and Flutter plugin](
+https://antigravity.google/docs/build-with-google/#dart-and-flutter)
+in Antigravity, you can invoke the accessibility agent directly when chatting
+with Antigravity by selecting the **Flutter Accessibility Agent** from the
+agent picker, mentioning `@flutter_a11y_agent`, or asking your assistant to
+review your code for accessibility:
+
+```text
+@flutter_a11y_agent Audit this screen for accessibility issues.
+```
