It installs managed instructions, hooks, MCP configuration, runtime files, and plugins that subsequently execute package adapters during agent events. - **Trigger:** npm global install/update, which runs postinstall - **Impact:** Unconsented persistent control of Copilot, Claude, Codex, Gemini, Grok, and Cursor agent behavior. - **Evidence paths:** scripts/postinstall.js, scripts/lib/npm-lifecycle-adapter.js, scripts/lib/global-host-target.js, scripts/lib/global-host-config.js, hooks/\_runtime/host-hook-launcher.cjs - **Review source:** ai\_review - **Reviewed:** 2026-08-23T07:18:01.613Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall-driven multi-host AI-agent configuration and hook deployment - **Attack narrative:** During npm global installation, the postinstall path calls global host configuration. The target list covers six third-party AI-agent home directories, where the package adds instructions, hooks, MCP entries, runtime files, and plugins. The installed host launcher later spawns package adapters on agent lifecycle events. This is an unconsented install-time mutation of a broad foreign AI-agent control surface. - **Rationale:** Source inspection confirms a concrete postinstall chain that automatically configures multiple foreign AI-agent environments on global install. This meets the supplied blocking boundary despite no confirmed network exfiltration. - **Files touched:** scripts/postinstall.js, scripts/lib/npm-lifecycle-adapter.js, scripts/lib/global-host-config.js, scripts/lib/global-host-target.js, ~/.copilot/hooks/devcodex.json, ~/.claude/settings.json, ~/.codex/hooks.json, ~/.codex/config.toml, ~/.gemini/settings.json, ~/.grok/config.toml, ~/.cursor/hooks.json ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** npm postinstall invokes the lifecycle adapter., On global installation, postinstall executes global host configuration., The default target set spans Copilot, Claude, Codex, Gemini, Grok, and Cursor user homes., Configuration plans add hooks, MCP servers, instructions, and plugins to those agent surfaces. - **Evidence against:** Workspace installs are skipped and instruct users to install globally., No credential exfiltration or network endpoint was confirmed in inspected lifecycle paths., Writes are managed transactions with scoped path checks, but remain unconsented broad agent-control mutation. ## Public findings ### 1.
