It installs hooks, instructions, plugins, and MCP configuration. - **Trigger:** npm install -g devcodex - **Impact:** Unconsented broad control of third-party AI-agent behavior and tool registration. - **Evidence paths:** package.json, scripts/lib/npm-lifecycle-adapter.js, scripts/lib/global-host-target.js, scripts/lib/global-host-config.js - **Review source:** ai\_review - **Reviewed:** 2026-08-23T04:27:46.205Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall applies multi-host AI-agent configuration - **Attack narrative:** The package declares postinstall. During a global npm installation, its lifecycle adapter automatically calls global host configuration. The target resolver selects user-home configuration roots for six unrelated AI-agent products, and the planner merges hooks and managed MCP configuration into them. This is an unconsented install-time mutation of a broad foreign AI-agent control surface. - **Rationale:** Source confirms the critical behavior directly; the workspace and CI guards do not mitigate automatic mutation on ordinary global installation. - **Files touched:** package.json, scripts/postinstall.js, scripts/lib/npm-lifecycle-adapter.js, scripts/lib/global-host-target.js, scripts/lib/global-host-config.js ### 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 install, postinstall executes global host configuration without a CLI confirmation., It targets six third-party AI-agent user configuration roots., The configuration plan adds Codex hooks and managed MCP configuration. - **Evidence against:** Workspace installs are skipped and instructed to use a global install., CI installs are skipped unless forced. ## Public findings ### 1.
