## Verdict summary
**Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Warn-only agent extension risk
- **Public report status:** Published
- **Threat category:** Agent extension lifecycle risk
- **Selected version:** 0.13.1
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

LPM treats this as warn-only first-party agent extension lifecycle risk. A global install emits agent-directed instructions that can lead an AI agent to configure several unrelated agent platforms. The later setup command adds persistent guidance and executable hooks.

## Security analysis

### Published attack-surface review

- **Summary:** A global install emits agent-directed instructions that can lead an AI agent to configure several unrelated agent platforms. The later setup command adds persistent guidance and executable hooks.

- **Trigger:** Global npm installation followed by an AI agent obeying the postinstall message and running setup.

- **Impact:** Persistent commands and instructions can be added to Claude, Codex, Grok, or Gemini agent environments.

- **Evidence paths:** package.json, scripts/postinstall.mjs, dist/index.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-28T13:42:54.414Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** Agent-directed lifecycle prompt followed by cross-platform agent configuration and hook installation.

- **Rationale:** The package has a real cross-agent extension installer and persistent hook capability, reached through agent-directed global postinstall messaging. The install hook itself only prints and setup includes user questions, so the source does not prove direct unconsented mutation during npm installation.

- **Files touched:** scripts/postinstall.mjs, dist/index.js, ~/.claude/CLAUDE.md, ~/.claude/settings.json, ~/.codex/AGENTS.md, ~/.codex/hooks.json, ~/.grok/rules/memgineering.md, ~/.grok/hooks/memgineering.json, ~/.gemini/GEMINI.md

- **Network endpoints:** https://api.memgineering.com, https://registry.npmjs.org/memgineering/latest, https://memgineering.com/version-policy.json

### 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 run setup in the same turn., Setup writes guidance, skills, and hooks into several foreign AI-agent home directories., The installed hooks launch memgineering commands at session and tool events., The lifecycle text addresses an AI agent directly, which is reviewer and agent manipulation.

- **Evidence against:** The postinstall script only prints when installed globally and does not itself write files., Setup asks the user to choose storage and settings before it runs., Network requests use the package's named API and npm registry endpoints., No self-dependency, obfuscated payload, or install-time credential harvesting was found.
