Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 18 low-signal pattern(s) reviewed. - **Verdict:** Clean - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Published - **Threat category:** None published - **Selected version:** 1.8.0 - **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. The lifecycle hook does not configure an agent, and the Claude settings change occurs through the separate installer flow. The inspected uninstall logic removes only ACK-marked hooks, so the scanner’s risk labels are not supported as malicious behavior by these sources. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-17T04:17:23.675Z - **Finished:** 2026-10-17T04:18:18.039Z - **Download time:** 504 ms - **Static scan time:** 558 ms - **AI review time:** 53301 ms - **Total time:** 54364 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:** No attack surface was identified in the inspected source. The install hook provides setup guidance, while Claude hook configuration is handled by the separate installer command. - **Trigger:** Package installation runs postinstall; agent configuration requires invoking the installer command. - **Impact:** No unconsented agent configuration change or other concrete attack was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-17T04:18:18.039Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall checks installation context, detects harness markers, and prints guidance. The explicit installer adds its own hooks, and preuninstall removes ACK-marked entries. - **Rationale:** The lifecycle hook does not configure an agent, and the Claude settings change occurs through the separate installer flow. The inspected uninstall logic removes only ACK-marked hooks, so the scanner’s risk labels are not supported as malicious behavior by these sources. ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest’s postinstall hook runs node/bin/postinstall.js; its source gates output on a global install inside node\_modules and directs users to run setup separately., The installer’s Claude settings target is the user’s .claude/settings.json; its hook entries are added by the installer flow., Preuninstall removes ACK-marked Claude hooks while preserving unrelated settings., The knowledge indexer’s cited location lists agent configuration filenames among files excluded from indexing., The Claude hook launcher runs the ACK command and exits nonzero if it cannot run., Harness detection checks for local marker paths and returns detected harness names. - **Evidence against:** No attack was identified: postinstall only detects installed harnesses and prints setup guidance; it does not configure them., Agent hook setup is performed by the separate installer command, and uninstall cleanup is limited to ACK-marked hook entries. ## Affected versions and remediation This report applies to @drdeeks/character-kit@1.8.0. - Review the evidence and your use of @drdeeks/character-kit@1.8.0 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.
