It installs all supported CLI adapters and framework files. - **Trigger:** npm install of izanagi-ai as a dependency - **Impact:** Future AI CLI sessions may load package-provided instructions and agents. - **Evidence paths:** package.json, bin/postinstall.js, dist/scripts/postinstall.js, dist/installer.js, dist/exporters.js, skills/ui-ux-pro-max/scripts/tests/test\_core.py - **Review source:** ai\_review - **Reviewed:** 2026-08-23T05:41:23.934Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** unconsented postinstall project-wide AI-agent configuration injection - **Attack narrative:** Installing the package invokes a bootstrap that imports the lifecycle implementation. For dependency installs it uses npm’s INIT\_CWD as the consumer project, then calls the installer with every pack and target CLI set to all. The installer copies framework content into .agents, writes root AGENTS.md/SYSTEM.md/RULES.md, creates opencode.json, and generates adapters for Claude, Cursor, Codex, Copilot, Kimi, and OpenCode. This is an unconsented install-time mutation of a broad foreign AI-agent control surface. - **Rationale:** Source confirms concrete npm postinstall mutation of the consuming project’s multi-vendor AI-agent configuration surface. This meets the blocking policy regardless of the absence of confirmed exfiltration. - **Files touched:** bin/postinstall.js, dist/scripts/postinstall.js, dist/installer.js, \/.agents, \/AGENTS.md, \/SYSTEM.md, \/RULES.md, \/opencode.json, \/.izanagi/izanagi.config.json ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** postinstall runs automatically on npm install., Lifecycle code targets INIT\_CWD and activates every CLI adapter., Installer copies agent instructions into the project and writes root control files. - **Evidence against:** No credential harvesting or unrelated network endpoint was confirmed., The flagged Python file is ordinary unittest source, not a payload. ## Public findings ### 1.
