Summary
summary.usage/node_summary.usage, but the SDK exposes these assummary.tokens/node_summary.tokens. PR fix: Use tokens= instead of usage= on LDAIMetrics constructors #30 fixed LDAIMetrics constructors but missed these read sites. Without this fix the example crashes with AttributeError when it reaches the metrics print block..usageread appears on metric-summary objects across the other examples (create_agent, langgraph react + multi-agent, langchain, openai, bedrock, gemini); all are updated to.tokenshere so the whole example suite stays consistent.Test plan
poetry run agent-graphagainst a project with a configured agent graph; verify token counts print without AttributeError.🤖 Generated with Claude Code
