coding-harness-tracing is a plugin marketplace that automatically traces Claude Code sessions to Arize AX or Phoenix using OpenInference spans.
About
coding-harness-tracing is an Arize AI Claude marketplace entry with one plugin that wires Claude Code sessions into enterprise-grade agent observability. developers and small teams running coding agents in production install it when they need reproducible spans instead of guessing what the harness did on a failed run. The claude-code-tracing plugin emits OpenInference-compatible traces to Arize AX or Phoenix, which fits stacks that already standardize on Arize for LLM and agent monitoring. It is not a skill that changes how you prompt; it is infrastructure that records tool use, turns, and outcomes so you can compare sessions, share links with collaborators, and tighten loops during Operate. Prerequisites are a Claude Code setup plus Arize or Phoenix project credentials. Best paired with error triage and iteration workflows once shipping pressure is real.
