 The `claude_env` input accepts YAML format where each line defines a key-value pair. These environment variables will be available to Claude Code during execution, allowing it to run tests, build processes, or other commands that depend on specific environment configurations.
 
+### Limiting Conversation Turns
+
+You can use the `max_turns` parameter to limit the number of back-and-forth exchanges Claude can have during task execution. This is useful for:
+
+- Controlling costs by preventing runaway conversations
+- Setting time boundaries for automated workflows
+- Ensuring predictable behavior in CI/CD pipelines
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    max_turns: "5" # Limit to 5 conversation turns
+    # ... other inputs
+```
+
+When the turn limit is reached, Claude will stop execution gracefully. Choose a value that gives Claude enough turns to complete typical tasks while preventing excessive usage.
