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. LPM treats this as warn-only first-party agent extension lifecycle risk. Installation automatically configures Claude Code when its configuration file exists. It adds package-selected settings and installs a package-owned statusline script. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-10-07T19:21:51.394Z - **Finished:** 2026-10-07T19:22:17.540Z - **Download time:** 255 ms - **Static scan time:** 331 ms - **AI review time:** 25559 ms - **Total time:** 26146 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 configures Claude Code when its configuration file exists. It adds package-selected settings and installs a package-owned statusline script. - **Trigger:** Installing the npm package invokes its postinstall script. - **Impact:** The install changes the user's agent configuration and behavior. The source indicates package-owned integration, with no evidence here of credential theft or a malicious payload. - **Evidence paths:** package.json, scripts/postinstall.js, src/utils/util-claude-config.js - **Review source:** ai\_review - **Reviewed:** 2026-10-07T19:22:17.540Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The script calls Claude configuration setup without a separate user command; setup modifies Claude configuration and copies a statusline script into the Claude directory. - **Rationale:** The package performs automatic, guarded changes to Claude Code configuration during npm installation, which merits a warning under the agent integration policy. The inspected behavior is package-owned setup and does not establish a concrete malicious attack. - **Files touched:** package.json, scripts/postinstall.js, src/utils/util-claude-config.js, src/commands/completion.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The manifest runs a postinstall script during installation., The postinstall script automatically calls Claude Code configuration and shell completion setup., When Claude Code is detected, the configuration routine updates its settings and installs a statusline script., That configuration enables package-selected plugins and sets a custom statusline command. - **Evidence against:** Claude configuration is gated on an existing Claude Code configuration file., The shell completion entry is package-specific and loads the pvs completion script. ## Affected versions and remediation This report applies to @preventsenior/pvs-cli@3.7.1. - Review the evidence and your use of @preventsenior/pvs-cli@3.7.1 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.
