## Verdict summary
**Passed — safe to install** — No malicious behavior detected. 22 low-signal pattern(s) reviewed.

- **Verdict:** Clean
- **Product-default install policy:** Allow
- **Firewall policy:** No policy match
- **Public report status:** Published
- **Threat category:** None published
- **Selected version:** 1.0.80
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

No confirmed malicious attack surface was established. The runtime CLI is an opt-in coding agent; its privileged capabilities are aligned with that stated purpose.

## Security analysis

### Published attack-surface review

- **Summary:** No confirmed malicious attack surface was established. The runtime CLI is an opt-in coding agent; its privileged capabilities are aligned with that stated purpose.

- **Trigger:** User runs the yorn CLI or explicitly uses its skills.

- **Impact:** Can access project files, execute user-directed commands, and use configured AI-provider credentials during normal CLI operation.

- **Evidence paths:** package.json, README.md, dist/yorn.cjs, dist/skills/screenshot/scripts/ensure\_macos\_permissions.sh, dist/skills/screenshot/scripts/take\_screenshot.ps1

- **Review source:** ai\_review

- **Reviewed:** 2026-08-23T10:18:13.913Z

### AI review details

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

- **Mechanism:** User-invoked AI coding agent and screenshot helper.

- **Rationale:** Direct inspection found no install-time execution, credential exfiltration endpoint, stealth persistence, or foreign AI-agent control-surface mutation. Scanner hits reflect the declared AI coding-agent and screenshot capabilities.

### Review decision

- **Verdict:** Clean

- **Confidence:** 84.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Medium

- **Evidence for:** Only lifecycle hook is prepublishOnly, not install-time., The package exposes an opt-in yorn CLI entrypoint., Screenshot permission request is explained before invocation.

- **Evidence against:** Runtime coding-agent functionality includes network, credential storage, file access, and command execution., README describes an automatic global self-update check.
