A dependency installation can alter how multiple AI coding tools load instructions and agents in an unrelated project. - **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:** 3.21.0 - **Selected version is latest:** No - **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 modifies the consuming project’s AI-agent configuration surface. It creates framework files, root instruction documents, OpenCode configuration, and adapters for every supported AI CLI. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-08T13:35:52.652Z - **Finished:** 2026-09-08T13:37:19.754Z - **Download time:** 507 ms - **Static scan time:** 2536 ms - **AI review time:** 84058 ms - **Total time:** 87102 ms The recorded confidence comes from the underlying analysis.

It creates framework files, root instruction documents, OpenCode configuration, and adapters for every supported AI CLI. - **Trigger:** npm installation runs postinstall. - **Impact:** A dependency installation can alter how multiple AI coding tools load instructions and agents in an unrelated project. - **Evidence paths:** package.json, dist/scripts/postinstall.js, dist/installer.js - **Review source:** ai\_review - **Reviewed:** 2026-09-08T13:37:19.754Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic broad AI-agent configuration injection into the consumer project. - **Attack narrative:** During npm installation, package.json runs bin/postinstall.js, which delegates to dist/scripts/postinstall.js. When installed as a dependency, it uses the consumer install directory and calls installToProject with every pack and the all-CLI option. The installer recursively copies framework content into .agents, writes root instruction documents and configuration, creates opencode.json, and generates adapters for several AI coding platforms. This is an unconsented postinstall mutation of a broad foreign AI-agent control surface. - **Rationale:** The automatic postinstall chain modifies the consumer project and configures multiple AI-agent platforms without an explicit user command. This meets the install-control-surface block criterion. - **Files touched:** .agents/, AGENTS.md, SYSTEM.md, RULES.md, .izanagi/izanagi.config.json, opencode.json, .claude/, .codex/, .cursor/, .github/, .kimi/, .opencode/ ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package runs a postinstall hook automatically during consumer installation., The hook targets the consumer project through INIT\_CWD and invokes the installer without user interaction., The installer copies framework packs into the consumer project and writes AI-agent control files., Postinstall requests adapters for all supported AI CLIs, including Codex, Claude, Cursor, Copilot, Kimi, and OpenCode. - **Evidence against:** No runtime dependency on izanagi-ai itself was found in package.json., The reviewed install path does not send network requests or harvest credentials. ## Affected versions and remediation This report applies to izanagi-ai@3.21.0. - Avoid installing izanagi-ai@3.21.0. 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.
