This is an unconsented broad agent control-surface mutation. - **Trigger:** npm install -g devcodex or global npm update - **Impact:** Subsequent Copilot, Claude, Codex, Gemini, Grok, and Cursor sessions can load package-controlled hooks and MCP runtimes. - **Evidence paths:** package.json, scripts/postinstall.js, scripts/lib/npm-lifecycle-adapter.js, scripts/lib/global-host-config.js, scripts/lib/global-host-target.js - **Review source:** ai\_review - **Reviewed:** 2026-08-12T02:50:56.129Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall-driven multi-host AI-agent configuration deployment - **Attack narrative:** Installing the package globally triggers postinstall automatically. The lifecycle adapter calls the global host configurator, which resolves six user-level AI-agent roots and writes package-controlled instruction files, hooks, MCP server definitions, plugins, and runtime dependencies there. These are persistent integrations activated by later agent sessions, not merely package-local setup. Although the implementation has path-boundary checks and no inspected exfiltration path, the automatic install-time modification of multiple foreign agent control surfaces is concrete and broad. - **Rationale:** The package performs unconsented postinstall mutation of broad, foreign AI-agent control surfaces during global installation. Under the stated policy this is block-worthy even without separate exfiltration behavior. - **Files touched:** scripts/postinstall.js, scripts/lib/npm-lifecycle-adapter.js, scripts/lib/global-host-config.js, scripts/lib/global-host-target.js, $HOME/.copilot, $HOME/.claude, $HOME/.codex, $HOME/.gemini, $HOME/.grok, $HOME/.cursor ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The npm postinstall executes configuration on every global install., It deploys hooks, MCP servers, instructions, and runtime code into six user-level AI-agent surfaces. - **Evidence against:** No credential-harvesting or network-exfiltration path was found in the inspected lifecycle/configuration code., Writes are bounded to declared host roots, but still alter broad foreign agent control surfaces without an explicit command. ## Public findings ### 1.
