+# Codex Package (agent-framework-codex)
+
+Integration with OpenAI Codex as a managed agent (Codex SDK).
+
+## Main Classes
+
+- **`CodexAgent`** - Agent using Codex's native agent capabilities
+- **`CodexAgentOptions`** - Options for Codex agent configuration
+- **`CodexAgentSettings`** - TypedDict-based settings populated via the framework's `load_settings()` helper
+
+## Usage
+
+```python
+from agent_framework_codex import CodexAgent
+
+agent = CodexAgent(...)
+response = await agent.run("Hello")
+```
+
+## Import Path
+
+```python
+from agent_framework_codex import CodexAgent
+```
+
+## Note
+
+This package is for Codex's managed agent functionality. For basic OpenAI chat, use `agent-framework-openai` instead.
