r/ClaudeAI: Developer Ships Meridian — Open-Source OpenTelemetry Dashboard That Maps Token Waste Patterns in Live Claude Code Sessions

A developer open-sourced Meridian, a tool that plugs into Claude Code's native OpenTelemetry telemetry to surface token waste patterns in real time — capturing token counts, durations, full tool call commands, and session IDs per LLM request. The post targets teams hit by unexplained Claude Code session cost spikes, a pain point that has generated significant community discussion following reports of five- and six-figure monthly bills. Community interest is early but high; no paper or external benchmarks accompany the release.
