## 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:** 0.25.6
- **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. Installation automatically repairs the Electron dependency by invoking its installer. Separately, a user can install remotely supplied skills into Beast's own agent-skill directory.

## Security analysis

### Published attack-surface review

- **Summary:** Installation automatically repairs the Electron dependency by invoking its installer. Separately, a user can install remotely supplied skills into Beast's own agent-skill directory.

- **Trigger:** npm installation triggers postinstall; clicking a Store install button triggers remote skill installation.

- **Impact:** A compromised Electron distribution path or community skill index could introduce code into the application's runtime or agent extension area.

- **Evidence paths:** package.json, scripts/fix-electron.js, src/agent/store.js, src/renderer/renderer.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-31T20:14:26.887Z

### AI review details

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

- **Mechanism:** Automatic dependency repair and user-invoked remote skill deployment.

- **Rationale:** The package has risky automatic dependency repair and a remote, user-invoked agent-skill installation path. The behavior is not sufficient to establish malicious intent, but it warrants a warning under the extension lifecycle policy.

- **Files touched:** scripts/fix-electron.js, node\_modules/electron/dist, src/agent/store.js, %APPDATA%\\beast\\skills\\\<id\>, src/renderer/renderer.js

- **Network endpoints:** https://raw.githubusercontent.com/algokodcom/beast-agent/main/store/skills.json, https://npmmirror.com/mirrors/electron/

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 87.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for:** The automatic postinstall runs a repair script., That script removes Electron's installed runtime directory and runs Electron's installer., A user-selected store action fetches remote skill data and writes its files into the agent's skill directory.

- **Evidence against:** The manifest has no runtime dependency on beast-agent itself., The postinstall target is the declared Electron dependency, not an AI-agent control surface., Remote skill installation is initiated by a Store button click and is limited to Beast's own skills directory.
