This establishes automatic runtime hooks across those hosts without a separate user command. - **Trigger:** npm install -g devcodex - **Impact:** Subsequent Copilot, Claude, Codex, Gemini, Grok, and Cursor sessions can execute package-provided lifecycle adapters. - **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, scripts/lib/global-host-config-transaction.js - **Review source:** ai\_review - **Reviewed:** 2026-08-11T22:57:30.953Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall-driven multi-host AI-agent config and hook injection - **Attack narrative:** A global npm install runs postinstall automatically. The lifecycle adapter classifies that install as executable, builds plans for six agent hosts, merges instructions/hooks/MCP entries into their user-level configuration, and transactionally writes the resulting files and runtime payloads. These hooks invoke package-owned lifecycle adapters in later agent sessions. Although writes are path-bounded and no exfiltration endpoint was found, install-time mutation of multiple foreign AI-agent control surfaces is concrete and unconsented. - **Rationale:** This is a concrete install-time broad AI-agent control-surface mutation, which meets the blocking policy. Guardrails and lack of network exfiltration reduce collateral risk but do not remove the unauthorized persistence mechanism. - **Files touched:** scripts/postinstall.js, scripts/lib/npm-lifecycle-adapter.js, scripts/lib/global-host-config.js, scripts/lib/global-host-target.js, ~/.copilot, ~/.claude, ~/.codex, ~/.gemini, ~/.grok, ~/.cursor, ~/.agents ### 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., Global installs execute an internal global-host configuration action., The default target set spans Copilot, Claude, Codex, Gemini, Grok, and Cursor user homes., Install-time plans merge user instructions, hooks, and MCP settings, then write them transactionally., No package-aligned network or credential-exfiltration path was found; the concrete risk is unconsented broad agent control-surface mutation. - **Evidence against:** Workspace installs are explicitly skipped and advised to use a global install., Writes are bounded to declared host roots/files and use staged transactional replacement., No production http/https/fetch client was found in the inspected runtime source. ## Public findings ### 1.
