+## Conversation Resumption
+
+The action outputs a `session_id` that allows you to resume Claude conversations across multiple workflow steps. This enables powerful multi-step workflows where you can run intermediate GitHub Actions steps and then continue the same Claude conversation with full context preserved.

+### Multi-Step Analysis Workflow
+
+```yaml
+steps:
+  # Step 1: Initial Claude analysis
+  - uses: actions/checkout@v4
+
+  - uses: anthropics/claude-code-action@v1

+### Use Cases for Conversation Resumption
+
+- **Multi-repo analysis**: Check out additional repositories and let Claude analyze them in context
+- **External data integration**: Fetch data from APIs, databases, or other services mid-conversation
+- **Staged execution**: Run tests or builds between Claude interactions
+- **Human-in-the-loop**: Allow manual approval steps before continuing automation
