Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The package has a real user-invoked global agent-extension and telemetry capability, including silent global skill installation. Its install lifecycle is inert and the broader tracing setup is explicitly gated, so the source supports a warning rather than a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-07T20:41:14.584Z - **Finished:** 2026-09-07T20:42:31.855Z - **Download time:** 258 ms - **Static scan time:** 123 ms - **AI review time:** 76889 ms - **Total time:** 77271 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Installation itself only prints a message. Running the interactive command and selecting an agent installs remote Arize skills globally without a separate confirmation; a later, explicitly approved flow can add machine-wide tracing that exports agent content. - **Trigger:** Run npx evals, select a detected coding agent, and later explicitly approve agent tracing. - **Impact:** Remote skills can persist in the selected agent's global scope; approved tracing can send prompts and tool data to Arize. - **Evidence paths:** cli.js, onboarding-prompt.md, analytics.js, vendor/coding\_harness\_tracing-0.1.0-py3-none-any.whl - **Review source:** ai\_review - **Reviewed:** 2026-09-07T20:42:31.855Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Global remote skill installation and opt-in agent-session telemetry. - **Rationale:** The package has a real user-invoked global agent-extension and telemetry capability, including silent global skill installation. Its install lifecycle is inert and the broader tracing setup is explicitly gated, so the source supports a warning rather than a block. - **Files touched:** ~/.arize/anon\_client\_id, ~/.arize/onboarding, ~/.arize/harness, ~/.codex/config.toml - **Network endpoints:** https://app.arize.com/api/analytics/npx-evals, https://github.com/Arize-ai/coding-harness-tracing.git ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** After a user selects an agent, the CLI silently runs an unpinned remote global skills installation with confirmation suppressed., The bundled agent-tracing flow is machine-wide and can collect prompts, tool commands, paths, URLs, and tool output after an explicit approval., The bundled analytics code persists a stable anonymous identifier and posts allowlisted funnel events to Arize. - **Evidence against:** The only npm postinstall action prints a message; it does not modify files or launch code., The tracing prompt prominently requires a separate explicit yes before installing the harness or enabling capture., No self-dependency, obfuscated loader, credential harvesting, or automatic install-time agent-control mutation was found. ## Affected versions and remediation This report applies to evals@2.10.0. - Review the evidence and your use of evals@2.10.0 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
