## Verdict summary
**Soft block: AI-agent control surface** — Warn by default; block when configured. Persistent package-controlled behavior can be activated in Copilot, Claude, Codex, Gemini, and Grok user sessions.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Warn by default
- **Public report status:** Published
- **Threat category:** Soft block: AI-agent control surface
- **Selected version:** 1.16.5
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

LPM flags this version as an AI-agent control-surface risk. A global npm install automatically mutates several foreign AI-agent user control surfaces. The postinstall deploys package-controlled hooks, instructions, MCP servers, skills, and a Grok plugin.

## Security analysis

### Published attack-surface review

- **Summary:** A global npm install automatically mutates several foreign AI-agent user control surfaces. The postinstall deploys package-controlled hooks, instructions, MCP servers, skills, and a Grok plugin.

- **Trigger:** npm install -g devcodex

- **Impact:** Persistent package-controlled behavior can be activated in Copilot, Claude, Codex, Gemini, and Grok user sessions.

- **Evidence paths:** package.json, scripts/postinstall.js, scripts/lib/npm-lifecycle-adapter.js, scripts/lib/global-host-config.js, scripts/lib/global-host-target.js, scripts/lib/global-host-config-transaction.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-09T10:39:04.560Z

### AI review details

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

- **Mechanism:** postinstall-driven multi-host global agent configuration deployment

- **Attack narrative:** On global installation, postinstall calls applyGlobalHostConfig without interactive consent or host selection. That routine resolves user-level directories for five AI-agent products and deploys DevCodex instructions, hooks, MCP configuration, runtime files, skills, and a Grok plugin. These changes alter broad foreign agent control surfaces automatically and persist beyond the npm command.

- **Rationale:** The global-install lifecycle path is a concrete unconsented postinstall mutation of broad foreign AI-agent control surfaces. Guardrails and lack of observed network activity do not remove that policy violation.

- **Files touched:** ~/.copilot, ~/.claude, ~/.codex, ~/.gemini, ~/.grok, ~/.agents

### Review decision

- **Verdict:** Malicious

- **Confidence:** 98.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** package.json runs scripts/postinstall.js., npm-lifecycle-adapter executes on global npm install., global-host-config targets Copilot, Claude, Codex, Gemini, and Grok., It writes global instructions, hooks, MCP config, skills, and Grok plugin registration., No consent or host-selection prompt guards the global-install path.

- **Evidence against:** Workspace and CI installs generally no-op., Reviewed lifecycle/config paths contain no network exfiltration., Writes are path-bounded and transactional.
