Building a Multi-Agent Code Review Crew with OpenTelemetry Tracing in SigNoz

Building a Multi-Agent Code Review Crew with OpenTelemetry Tracing in SigNoz

Original: I Built a Crew of AI Agents That Review Code Like a Real Team — Then Watched Them Argue With SigNoz

Short summary

A developer built a multi-agent code review crew with Logic, Style, and Performance reviewers plus a Moderator agent, then instrumented it with OpenTelemetry in SigNoz. Tracing revealed the performance reviewer was the latency bottleneck and the style reviewer consumed the most tokens — insights invisible without observability. The post covers practical debugging of span nesting and attribute setting in agent pipelines.

  • •Multi-agent code review crew with three specialist agents and a moderator, traced via OpenTelemetry
  • •SigNoz traces revealed performance reviewer as latency bottleneck and style reviewer as token cost leader
  • •Practical lessons on span nesting bugs and setting span attributes correctly for LLM calls
