## Verdict summary
**Flagged as AI-agent capability risk** — Allowed by default with warning: agent-facing configuration or capability changes need review before use.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Warn-only AI-agent capability risk
- **Public report status:** Published
- **Threat category:** AI-agent capability abuse
- **Selected version:** 0.27.0
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

Review flagged AI-agent configuration or capability changes. This remains warn-only unless evidence shows foreign-agent hijack through preinstall/install/postinstall, hidden persistence, exfiltration, remote code execution, or other concrete malicious behavior.

## Security analysis

### Published attack-surface review

- **Summary:** This is a local AI agent with model-callable PowerShell execution and file writes. Its optional approval gate is disabled by default. Requested extensions and Python use can fetch remote content and place executable material on disk.

- **Trigger:** A user, connected chat, or model tool call invokes command, skill-installation, or Python functionality.

- **Impact:** A prompt-influenced agent session can execute commands or modify files with the application's privileges.

- **Evidence paths:** src/agent/tools.js, src/agent/store.js, src/main.js

- **Review source:** ai\_review

- **Reviewed:** 2026-09-01T10:04:00.771Z

### AI review details

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

- **Mechanism:** Model-directed shell execution, file writing, and remote runtime or skill installation.

- **Rationale:** The package contains concrete dangerous agent capabilities with default-unrestricted execution, so it warrants a warning. Static inspection did not establish malicious intent or a concrete exfiltration or install-hook abuse chain.

- **Files touched:** %APPDATA%\\beast\\skills\\\<id\>, %APPDATA%\\beast\\py, %TEMP%\\beast-py-embed.zip

- **Network endpoints:** https://raw.githubusercontent.com/algokodcom/beast-agent/main/store/skills.json, https://www.python.org/ftp/python/3.12.8/python-3.12.8-embed-amd64.zip

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 88.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for:** The agent exposes PowerShell command execution and arbitrary file writes to model tool calls., Risky-tool approval is optional and the code states the default leaves everything allowed., A requested skill installation fetches community content and writes its files into the agent skill directory., The Python tool can download an embedded interpreter and execute it.

- **Evidence against:** No source path inspected sends harvested credentials or local files to an unrelated endpoint., The install hook repairs this package's Electron dependency; it does not alter an AI-agent control surface., The observed downloads use named package-aligned endpoints and are tied to advertised agent features.
