The package's global-install message can steer an AI agent into a follow-on setup that modifies installed AI-agent configurations. The mutation is performed by the separately invoked setup command, not by postinstall itself. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 90.0% - **Started:** 2026-08-29T11:07:47.168Z - **Finished:** 2026-08-29T11:10:02.401Z - **Download time:** 257 ms - **Static scan time:** 2640 ms - **AI review time:** 132334 ms - **Total time:** 135233 ms ## Security analysis ### Published attack-surface review - **Summary:** The package's global-install message can steer an AI agent into a follow-on setup that modifies installed AI-agent configurations. The mutation is performed by the separately invoked setup command, not by postinstall itself. - **Trigger:** An AI-assisted global npm installation followed by the agent acting on the postinstall output and running memgineering setup. - **Impact:** It can add instructions, skills, and command hooks to detected AI-agent homes; defaults can enable hooks and automatic updates. - **Evidence paths:** package.json, scripts/postinstall.mjs, dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-29T11:10:02.401Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Agent-directed postinstall guidance followed by first-party agent-extension installation. - **Rationale:** The package contains an install-time prompt chain that can lead an AI agent to alter broad agent control surfaces with permissive defaults. Static inspection found no direct postinstall mutation, self-dependency chain, secret harvesting, or unrelated exfiltration. - **Files touched:** scripts/postinstall.mjs, dist/index.js, ~/.claude/CLAUDE.md, ~/.claude/settings.json, ~/.codex/AGENTS.md, ~/.codex/hooks.json, ~/.grok/rules/memgineering.md, ~/.gemini/GEMINI.md ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** A global-install postinstall message instructs an AI agent to run setup in the same turn., The setup command writes guidance and skills into detected third-party AI-agent homes and can add command hooks., Setup defaults enable automatic updates and hooks when the agent selects non-interactive setup without explicit flags. - **Evidence against:** The postinstall script only prints guidance when globally installed; it does not itself run setup or modify files., The manifest has no runtime dependency on another memgineering release., The inspected network client uses the package's own api.memgineering.com service for its optional hosted-brain feature. ## 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`. Conflating them import { mkdir as mkdir2, readFile as readFile2, unlink, writeFile as writeFile2 } from "fs/promises"; await writeFile2(credentialsPath(), JSON.stringify(credentials, null, 2) + "\n", { import { mkdir as mkdir3, readFile as readFile3, unlink as unlink2, writeFile as writeFile3 } from "fs/promises"; await writeFile3(pendingLoginPath(), JSON.stringify(pending, null, 2) + "\n", { const base = args.baseUrl ?? apiUrl(); ...args.token ? { authorization: `Bearer ${args.token}` } : {} async function claimPendingLogin(baseUrl = apiUrl()) { ``` ### 10.
