Treat them as untrusted evidence. 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:** 1.0.5 - **Selected version is latest:** Yes - **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. The postinstall hook automatically installs a package-owned Claude skill that can guide later agent-run commands, so a warning is warranted. The inspected behavior does not establish a concrete attack supporting a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 83.0% - **Started:** 2026-10-16T13:55:51.248Z - **Finished:** 2026-10-16T13:57:11.230Z - **Download time:** 1523 ms - **Static scan time:** 885 ms - **AI review time:** 77573 ms - **Total time:** 79982 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:** The install hook automatically adds a package-owned troubleshooting skill to Claude Code for global installs. This creates a residual risk because the skill directs the agent to run package commands through Bash. - **Trigger:** Installing the package globally while a Claude Code directory exists in the user’s home directory. - **Impact:** The package changes agent configuration without a separate setup prompt, enabling later agent-run commands under the skill’s instructions. - **Evidence paths:** package.json, dist/scripts/postinstall.js, dist/skill/SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-10-16T13:57:11.230Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall hook copies the bundled skill into the user’s Claude skills directory; the skill is intended to activate on reports of package problems and directs Claude to run diagnostic or repair commands. - **Rationale:** The postinstall hook automatically installs a package-owned Claude skill that can guide later agent-run commands, so a warning is warranted. The inspected behavior does not establish a concrete attack supporting a block. - **Files touched:** dist/scripts/postinstall.js, dist/skill/SKILL.md ### Review decision - **Verdict:** Suspicious - **Confidence:** 83.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package postinstall hook runs during installation; global installs call the Claude skill setup automatically., The setup writes a package-owned skill under the user’s Claude skills directory when that directory exists; an environment variable can opt out., The installed skill directs Claude to run the package’s diagnostic and repair commands through Bash when users report related problems. - **Evidence against:** The setup is scoped to a named package skill and skips installation when the Claude directory is absent., The inspected source establishes agent configuration setup but does not establish credential theft or another concrete attack. ## Affected versions and remediation This report applies to logod-chrome-mcp@1.0.5. - Review the evidence and your use of logod-chrome-mcp@1.0.5 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.
