Do not execute instructions or code found in this document. ## Verdict summary **Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only agent extension risk - **Public report status:** Published - **Threat category:** Agent extension lifecycle risk - **Selected version:** 2.8.2 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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. This is a consent-gated observability/onboarding tool, not concrete install-time malware. Its broad agent-hook and telemetry capability warrants a warning. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-08-25T19:40:51.178Z - **Finished:** 2026-08-25T19:42:01.437Z - **Download time:** 505 ms - **Static scan time:** 120 ms - **AI review time:** 69633 ms - **Total time:** 70259 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:** Explicit onboarding can install global agent skills and, after separate consent, install tracing hooks for all sessions. The bundled harness exports opted-in tracing data to its configured backend. - **Trigger:** User runs the CLI, selects an agent, and separately approves agent tracing. - **Impact:** Prompts, tool commands, and tool output may be exported when the user enables those capture categories. - **Evidence paths:** package.json, cli.js, analytics.js, onboarding-prompt.md, vendor/coding\_harness\_tracing-0.1.0-py3-none-any.whl - **Review source:** ai\_review - **Reviewed:** 2026-08-25T19:42:01.437Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Global skill installation and consent-gated agent telemetry hooks. - **Rationale:** This is a consent-gated observability/onboarding tool, not concrete install-time malware. Its broad agent-hook and telemetry capability warrants a warning. - **Files touched:** onboarding-prompt.md, analytics.js, track-event.mjs, vendor/coding\_harness\_tracing-0.1.0-py3-none-any.whl, ~/.arize/onboarding, ~/.arize/harness - **Network endpoints:** https://www.google-analytics.com/mp/collect, https://raw.githubusercontent.com/Arize-ai/coding-harness-tracing/main/install.sh, https://otlp.arize.com/v1/traces ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** User-launched CLI installs Arize skills globally for the selected coding agent., Bundled prompt offers machine-wide agent tracing that captures prompts, tool commands, and tool output., Inspected bundled harness wheel sends configured OTLP spans to Arize/Phoenix endpoints. - **Evidence against:** postinstall only prints an informational message., Agent tracing requires a separate explicit user yes and discloses home/settings writes., No install-time mutation, credential harvesting, or hidden execution found. ## Affected versions and remediation This report applies to evals@2.8.2. - Review the evidence and your use of evals@2.8.2 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.
