Session Replay & Trace Analysis

Acerca de

The Session Replay skill is a specialized diagnostic tool for Claude Code that deep-dives into claude-trace JSONL files. Unlike standard conversation transcripts, it examines API-level metadata to help developers understand token usage patterns, identify recurring error categories—such as rate limits or timeouts—and optimize tool performance. It is particularly valuable for debugging failed sessions, managing API costs through efficiency metrics, and auditing the effectiveness of agentic tool calls across multiple sessions.
