Generating docs like this from PRs seems to be working really well — this all reads really well
Add documentation explaining how the Agents SDK routes server-to-client requests through the correct HTTP stream using the relatedRequestId parameter. This is particularly important for elicitation requests that need to flow through the same bidirectional stream as the tool call that triggered them. Includes: - Explanation of the routing behavior and priority - Code example showing how to use relatedRequestId with elicitInput - Technical details about stream mapping 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
