claude-code-observability

Query, analyze, and score Claude Code session traces in LangFuse. Use this skill whenever you need to check session costs, token usage, tool execution patterns, or agent performance in LangFuse. Also use when creating scores, investigating trace data, comparing runs, or when the user mentions LangFuse, observability, telemetry, traces, session costs, or wants to understand what happened in a previous Claude Code session. This skill covers both reading traces and writing scores/annotations back to LangFuse.
