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 performs automatic project-context agent skills setup through an opaque platform binary. The inspected source does not establish theft, destructive behavior, or unrelated network activity. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-09-27T06:45:31.614Z - **Finished:** 2026-09-27T06:46:09.542Z - **Download time:** 771 ms - **Static scan time:** 23 ms - **AI review time:** 37133 ms - **Total time:** 37928 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 automatically invokes a Customer.io platform binary to install agent skills in the consumer context. No confirmed credential theft, network exfiltration, or destructive action is present in the inspected launcher. - **Trigger:** npm postinstall during package installation. - **Impact:** This creates an automatic agent-extension lifecycle mutation whose final file targets and contents are not visible in this snapshot. - **Evidence paths:** package.json, .npm/postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-09-27T06:46:09.542Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall script selects a platform dependency, sets its working directory to the install project when available, and runs its skills-install command. - **Rationale:** The package performs automatic project-context agent skills setup through an opaque platform binary. The inspected source does not establish theft, destructive behavior, or unrelated network activity. ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The manifest automatically runs the postinstall launcher., The launcher changes to the installer's project directory and invokes the platform binary to install skills. - **Evidence against:** The inspected JavaScript launcher contains no direct network request, credential collection, or file-write operation., The platform binary that performs the skills installation is not included in this package snapshot. ## Affected versions and remediation This report applies to @customerio/cli@0.0.29. - Review the evidence and your use of @customerio/cli@0.0.29 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.
