What is claude-code-tracing?

Automatic recording of Claude Code sessions as traces, which are time-ordered records of prompts, tool calls, and other activity, in Arize AX or Phoenix.

It is for monitoring Claude Code sessions with OpenInference data and sending that activity to Arize AX or Phoenix.

It helps you inspect what happened during an AI coding session without manually recording each step.

Security

Grade A, and why

claude-code-tracing scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
