The global postinstall emits a prompt directing an agent to run the package's setup command. That later, explicit command can write package guidance and hooks into Claude, Codex, Grok, or Gemini agent homes; no install-time mutation occurs. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 91.0% - **Started:** 2026-08-23T09:11:54.889Z - **Finished:** 2026-08-23T09:12:59.580Z - **Download time:** 501 ms - **Static scan time:** 2046 ms - **AI review time:** 62143 ms - **Total time:** 64691 ms ## Security analysis ### Published attack-surface review - **Summary:** The global postinstall emits a prompt directing an agent to run the package's setup command. That later, explicit command can write package guidance and hooks into Claude, Codex, Grok, or Gemini agent homes; no install-time mutation occurs. - **Trigger:** User or an agent runs memgineering setup after a global installation. - **Impact:** Future agent sessions may execute memgineering recall/guard commands and receive memory content. - **Evidence paths:** package.json, scripts/postinstall.mjs, dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-23T09:12:59.580Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** explicit AI-agent guidance and hook registration - **Rationale:** This is not concrete malware: postinstall only emits stdout and the agent writes occur through a later setup command. Its agent-directed install messaging and optional persistent hooks warrant a warning-level lifecycle-risk verdict. - **Files touched:** scripts/postinstall.mjs, dist/index.js - **Network endpoints:** https://api.memgineering.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** Global postinstall prints agent-directed instructions to run setup., Explicit setup installs guidance and optional hooks into supported AI-agent homes., Hook installation registers package commands for session and pre-tool events. - **Evidence against:** Postinstall only writes stdout when globally installed; it does not invoke setup., Hosted API defaults to the package-aligned api.memgineering.com endpoint., Credentials are locally stored with restrictive file mode and bound to the issuing API URL., No install-time file harvesting, network request, shell execution, or agent-config write was found. ## 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, readFile, rename, rm, writeFile } from "fs/promises"; await writeFile(tmp, body, { encoding: "utf8", mode: 384 }); import { rename as rename2, rm as rm3, writeFile as writeFile2 } from "fs/promises"; await writeFile2(tmp, content, { encoding: "utf8", mode: 384 }); import { mkdir as mkdir3, readFile as readFile5, unlink, writeFile as writeFile3 } from "fs/promises"; await writeFile3(credentialsPath(), JSON.stringify(credentials, null, 2) + "\n", { import { mkdir as mkdir4, readFile as readFile6, unlink as unlink2, writeFile as wri ``` ### 10.
