One Triage Pass, Every Trace Format: Stop Letting Fragmentation Shrink Your Eval Coverage

One Triage Pass, Every Trace Format: Stop Letting Fragmentation Shrink Your Eval Coverage

Short summary

Agent traces fragment across four incompatible formats, limiting eval coverage. The author built adapters normalizing OpenClaw, LangSmith, OpenTelemetry, and AgentLens traces into a unified contract for deterministic triage. Tier-1 checks (token counts, timeouts, errors) run inline before model-based grading, providing unforgeable evidence.

  • •Trace format fragmentation (OpenClaw, LangSmith, OpenTelemetry, AgentLens) silently shrinks eval coverage
  • •Built adapter layer that normalizes all four formats into shared BuiltSession contract
  • •Deterministic triage on traces (token cost, timeouts, errors) runs before model-based grading for unforgeable evidence
