It can alter the behavior and instructions of installed Claude Code, Codex CLI, and Gemini CLI sessions without an explicit setup command. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.15.1 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. Installing the package automatically changes global instruction and skill locations for detected AI coding tools. It does so silently through npm postinstall. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-07T18:11:48.564Z - **Finished:** 2026-09-07T18:12:52.380Z - **Download time:** 506 ms - **Static scan time:** 1657 ms - **AI review time:** 61652 ms - **Total time:** 63816 ms The recorded confidence comes from the underlying analysis.

It does so silently through npm postinstall. - **Trigger:** npm installation runs postinstall. - **Impact:** It can alter the behavior and instructions of installed Claude Code, Codex CLI, and Gemini CLI sessions without an explicit setup command. - **Evidence paths:** package.json, scripts/postinstall.mjs, dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-07T18:12:52.380Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Silent setup writes bundled guidance into global AI-agent control files. - **Attack narrative:** An npm install launches the package's postinstall script, which runs \`kordis setup --silent\`. Setup detects global AI-agent directories and injects or updates bundled content in their instruction files, while also copying bundled skills. This is an automatic mutation of several foreign AI-agent control surfaces rather than a user-invoked setup action. - **Rationale:** The package contains a concrete silent postinstall chain that writes into global control files for multiple unrelated AI-agent tools. This meets the policy threshold for unconsented install-time AI-agent control-surface mutation. - **Files touched:** ~/.claude/CLAUDE.md, ~/.codex/AGENTS.md, ~/.gemini/GEMINI.md, ~/.claude/skills, ~/.codex/skills, ~/.gemini/skills ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package automatically runs a postinstall hook., The postinstall hook invokes setup silently on npm installation., Setup targets global instruction files for Claude Code, Codex CLI, and Gemini CLI., Setup creates, appends to, or replaces marked blocks in those global agent files without user interaction. - **Evidence against:** The install hook is guarded by the presence of the bundled CLI entrypoint., No network request or credential collection occurs in the inspected postinstall path. ## Affected versions and remediation This report applies to @rayul/kordis@0.15.1. - Avoid installing @rayul/kordis@0.15.1. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
