A global install prints instructions intended to cause an AI agent to run setup. That setup can write first-party guidance and hooks into supported agent configuration directories. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 90.0% - **Started:** 2026-08-29T18:09:55.939Z - **Finished:** 2026-08-29T18:12:23.257Z - **Download time:** 518 ms - **Static scan time:** 2700 ms - **AI review time:** 144099 ms - **Total time:** 147318 ms ## Security analysis ### Published attack-surface review - **Summary:** A global install prints instructions intended to cause an AI agent to run setup. That setup can write first-party guidance and hooks into supported agent configuration directories. - **Trigger:** A global npm install followed by an agent acting on the printed instructions and running memgineering setup. - **Impact:** It can alter Claude Code and Codex behavior and inject memory context into agent sessions. - **Evidence paths:** package.json, scripts/postinstall.mjs, dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-29T18:12:23.257Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Agent-directed setup installs guidance, skills, and optional hooks. - **Rationale:** The package uses install-time output to steer AI agents into a first-party configuration workflow that can modify broad agent control surfaces. The mutation is deferred to setup rather than performed automatically, so the evidence supports a warning rather than a block. - **Files touched:** scripts/postinstall.mjs, ~/.claude/CLAUDE.md, ~/.claude/skills/, ~/.claude/settings.json, ~/.codex/AGENTS.md, ~/.codex/skills/, ~/.codex/hooks.json, ~/.memgineering/credentials.json - **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:** The global postinstall script addresses an AI agent and directs it to continue setup in the same turn., Agent-mode setup selects all detected tools and defaults automatic updates and hooks to on., Setup writes guidance and skills into Claude and Codex home directories, then installs command hooks., The package sends authenticated requests only to its configured hosted-brain API after login. - **Evidence against:** Postinstall only prints instructions when globally installed; it does not itself modify agent configuration., Setup exposes interactive, web, and dry-run modes and can be configured without login., The API URL is a user environment setting with a package-owned default, not a fixed unrelated endpoint., No self-dependency, obfuscation, arbitrary shell execution, or secret harvesting was found. ## Public findings ### 1.
