A global install prints instructions aimed at an AI agent, encouraging it to run the separate setup command. That command can persist package guidance and hooks in detected AI-agent configuration directories. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 90.0% - **Started:** 2026-08-26T17:32:22.625Z - **Finished:** 2026-08-26T17:33:33.698Z - **Download time:** 509 ms - **Static scan time:** 2259 ms - **AI review time:** 68304 ms - **Total time:** 71073 ms ## Security analysis ### Published attack-surface review - **Summary:** A global install prints instructions aimed at an AI agent, encouraging it to run the separate setup command. That command can persist package guidance and hooks in detected AI-agent configuration directories. - **Trigger:** Global npm installation followed by an agent acting on the postinstall message and running memgineering setup. - **Impact:** Agent behavior can be persistently influenced and hooks can run on later sessions or tool use. - **Evidence paths:** package.json, scripts/postinstall.mjs, dist/index.js, assets/MEMGINEERING.md - **Review source:** ai\_review - **Reviewed:** 2026-08-26T17:33:33.698Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Agent-directed setup installs package-owned guidance and command hooks. - **Rationale:** This is a real, package-owned AI-agent extension lifecycle risk with an unusually directive install-time message. It does not meet the blocking threshold because the lifecycle script does not itself mutate foreign agent configuration and the subsequent setup path is separately invoked. - **Files touched:** scripts/postinstall.mjs, .claude/CLAUDE.md, .claude/settings.json, .claude/skills/memgineering-\*/SKILL.md, .codex/AGENTS.md, .codex/hooks.json, .codex/skills/memgineering-\*/SKILL.md - **Network endpoints:** https://api.memgineering.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** Global postinstall output directly instructs an AI agent to continue setup in the same turn., The setup command writes guidance and skills into Claude Code and Codex homes., Setup can add session-start and pre-tool hooks that run memgineering commands., The package has a hosted API, but its default endpoint is package-aligned. - **Evidence against:** Postinstall only prints guidance for global installs; it does not invoke setup itself., Setup is a separate command with tool detection and user-facing choices., No credential harvesting, covert exfiltration, remote payload execution, or destructive behavior was confirmed. ## Public findings ### 1.

High: Credential Redirect Persistence - **Category:** Source - **Confidence:** 94.0% - **Path:** dist/index.js - **Public source:** [View source]() Manifest-reachable source sends a prompted API credential to a fixed unofficial gateway and persists the redirection. Public source snippet (untrusted): ```javascript Manifest-reachable source captures an API credential, sends it to a fixed unofficial gateway, and persists that redirection in agent or shell configuration. dist/index.js: * it writes into somebody else's `~/.claude` and `~/.codex`.
