This is a broad foreign AI-agent control-surface mutation. - **Trigger:** npm install -g devcodex invokes postinstall. - **Impact:** Changes behavior and execution hooks of installed Copilot, Claude, Codex, Gemini, Grok, and Cursor clients. - **Evidence paths:** package.json, scripts/postinstall.js, scripts/lib/npm-lifecycle-adapter.js, scripts/lib/global-host-target.js, scripts/lib/global-host-config.js - **Review source:** ai\_review - **Reviewed:** 2026-08-12T14:22:04.979Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall applies managed host-adapter configuration and hook/MCP entries. - **Attack narrative:** A global npm install triggers postinstall without a separate setup command. The lifecycle adapter executes global host configuration, which targets six unrelated AI-agent user configuration roots and merges hooks/MCP configuration into them. Although workspace and CI guards exist and no exfiltration was found, this is unconsented install-time mutation of a broad foreign AI-agent control surface. - **Rationale:** The package performs concrete global postinstall rewrites across multiple third-party AI-agent control surfaces. That meets the firewall block boundary despite the absence of observed exfiltration. - **Files touched:** 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:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Install hook runs scripts/postinstall.js., On global npm install, postinstall executes applyGlobalHostConfig., It targets Copilot, Claude, Codex, Gemini, Grok, and Cursor user configuration roots., The generated plans merge hooks/MCP configuration into those host control surfaces. - **Evidence against:** Non-global installs no-op and direct users to a global install., CI installs are skipped unless explicitly forced., No credential exfiltration, remote payload fetch, or network endpoint was found in inspected paths. ## Public findings ### 1.
