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:** 0.5.2 - **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 install hook automatically adds this package's own skill to several agent skill roots, which fits the warning category for first-party package-owned agent extension setup. The inspected behavior does not establish a concrete malicious attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 93.0% - **Started:** 2026-10-12T12:36:12.678Z - **Finished:** 2026-10-12T12:37:00.644Z - **Download time:** 1029 ms - **Static scan time:** 34 ms - **AI review time:** 46902 ms - **Total time:** 47966 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 registers the package's bundled agent skill in several user-level skill directories. This is a first-party extension setup lifecycle risk; the inspected source does not establish a broader control-surface attack. - **Trigger:** npm installation invokes the postinstall lifecycle script. - **Impact:** The skill becomes available to the listed agent tools. In force mode, existing skill entries may be replaced or removed. - **Evidence paths:** package.json, scripts/postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-10-12T12:37:00.644Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The script creates a junction from each configured agent skill directory to the bundled publish-kit skill, while force mode can replace existing entries. - **Rationale:** The install hook automatically adds this package's own skill to several agent skill roots, which fits the warning category for first-party package-owned agent extension setup. The inspected behavior does not establish a concrete malicious attack. - **Files touched:** scripts/postinstall.js, package.json ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** package.json runs scripts/postinstall.js automatically after installation., The postinstall targets skill directories for five agent tools under the user's home directory., It creates a junction to the package's bundled publish-kit skill in each target directory., The package has a force option that can replace existing links or directories; this creates a lifecycle extension-registration risk. - **Evidence against:** Without force, the script skips existing links, junctions, and real directories., The inspected postinstall code only registers this package's bundled skill; no network endpoint or broader agent configuration write was found. ## Affected versions and remediation This report applies to @eternalnight/publish-kit@0.5.2. - Review the evidence and your use of @eternalnight/publish-kit@0.5.2 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.
