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:** 0.15.2 - **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 automatic postinstall can modify supported agents' global instruction files, which is a guarded first-party agent setup risk. Source inspection did not establish credential exfiltration or another concrete attack, so this merits a warning rather than a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-12T06:15:46.484Z - **Finished:** 2026-10-12T06:16:27.092Z - **Download time:** 773 ms - **Static scan time:** 752 ms - **AI review time:** 39082 ms - **Total time:** 40608 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 package postinstall hook can register Kordis guidance in global instruction files for supported AI agents. This is an agent configuration mutation risk, with no confirmed credential exfiltration or other attack established by the inspected code. - **Trigger:** Installing the npm package runs postinstall when the bundled distribution entry exists. - **Impact:** Agent behavior may be influenced by the added guidance. The inspected evidence does not establish credential theft or destructive impact. - **Evidence paths:** package.json, scripts/postinstall.mjs, dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-12T06:16:27.092Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook launches the CLI setup command silently; setup detects supported agent directories and writes guidance into their global instruction files. - **Rationale:** The automatic postinstall can modify supported agents' global instruction files, which is a guarded first-party agent setup risk. Source inspection did not establish credential exfiltration or another concrete attack, so this merits a warning rather than a block. - **Files touched:** package.json, scripts/postinstall.mjs, dist/index.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json defines a postinstall hook that runs the package's setup script., The postinstall script launches the CLI setup command silently when the distribution bundle exists., Setup targets global instruction files for Claude Code, Codex CLI, and Gemini CLI, and writes guidance into them., The setup command checks for installed agent directories before modifying their instruction files. - **Evidence against:** The inspected source does not support the scanner's claim that prompted API credentials are redirected to a fixed unofficial gateway., The setup behavior is a first-party package feature and no exfiltration or destructive behavior was established. ## Affected versions and remediation This report applies to @rayul/kordis@0.15.2. - Review the evidence and your use of @rayul/kordis@0.15.2 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.
