## Security analysis

### Published attack-surface review

- **Summary:** No confirmed malicious attack surface. The package is an interactive coding-agent CLI; its privileged capabilities are activated only when the user runs it.

- **Trigger:** User runs the yorn CLI.

- **Impact:** No unsolicited install-time action or concrete exfiltration chain found.

- **Evidence paths:** package.json, dist/yorn.cjs

- **Review source:** ai\_review

- **Reviewed:** 2026-08-23T06:34:14.283Z

### AI review details

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

- **Mechanism:** User-invoked coding-agent operations.

- **Rationale:** Static source inspection found a bundled interactive AI coding CLI with expected network, credential, shell, and filesystem capabilities, but no malicious chain. The scanner's credential and overwrite claims are not supported as unsolicited or foreign-targeting behavior.

- **Files touched:** dist/yorn.cjs

### Review decision

- **Verdict:** Clean

- **Confidence:** 94.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for:** Manifest exposes a user-invoked yorn CLI., Only prepublishOnly is declared; no npm install lifecycle hook.

- **Evidence against:** CLI network, shell, file, and credential features are aligned with an interactive coding agent., Config migration targets the package-owned .yorn agent directory., No source evidence of credential exfiltration, foreign-package overwrite, stealth persistence, or install-time execution.
