Security Audit
jimliu/baoyu-skills:skills/baoyu-url-to-markdown
github.com/jimliu/baoyu-skillsTrust Assessment
jimliu/baoyu-skills:skills/baoyu-url-to-markdown received a trust score of 10/100, placing it in the Untrusted category. This skill has significant security findings that require attention before use in production.
SkillShield's automated analysis identified 7 findings: 3 critical, 1 high, 2 medium, and 1 low severity. Key findings include Network egress to untrusted endpoints, Sensitive environment variable access: $HOME, Unpinned npm dependency version.
The analysis covered 4 layers: Manifest Analysis, Static Code Analysis, Dependency Graph, LLM Behavioral Safety. The Manifest Analysis layer scored lowest at 10/100, indicating areas for improvement.
Last analyzed on August 6, 2026 (commit 6b7a2e41). SkillShield performs automated 4-layer security analysis on AI skills and MCP servers.
Layer Breakdown
Behavioral Risk Signals
Security Findings7
| Severity | Finding | Layer | Location | |
|---|---|---|---|---|
| CRITICAL | Network egress to untrusted endpoints HTTP request to raw IP address Review all outbound network calls. Remove connections to webhook collectors, paste sites, and raw IP addresses. Legitimate API calls should use well-known service domains. | Manifest | skills/baoyu-url-to-markdown/scripts/lib/browser/chrome-launcher.ts:64 | |
| CRITICAL | Network egress to untrusted endpoints HTTP request to raw IP address Review all outbound network calls. Remove connections to webhook collectors, paste sites, and raw IP addresses. Legitimate API calls should use well-known service domains. | Manifest | skills/baoyu-url-to-markdown/scripts/lib/browser/chrome-launcher.ts:100 | |
| CRITICAL | Network egress to untrusted endpoints HTTP request to raw IP address Review all outbound network calls. Remove connections to webhook collectors, paste sites, and raw IP addresses. Legitimate API calls should use well-known service domains. | Manifest | skills/baoyu-url-to-markdown/scripts/lib/browser/profile.ts:140 | |
| HIGH | Automatic transmission of fetched URLs to third-party service (defuddle.md) The generic adapter converts HTML to markdown and, by default, enables a remote fallback (`enableRemoteMarkdownFallback`) when the output format is markdown. This fallback transmits the target URL to a third-party service (`https://defuddle.md`) to perform the conversion. If the user fetches internal, local, or authenticated URLs (which may contain sensitive tokens, session IDs, or private data in the URL path/query), this behavior leaks those URLs to an external service without explicit user consent. Disable `enableRemoteMarkdownFallback` by default, or prompt the user for consent before sending any URLs to the remote `defuddle.md` service. Alternatively, rely solely on local markdown conversion libraries (like `turndown` or a local `defuddle` instance). | LLM | scripts/lib/adapters/generic/index.ts:45 | |
| MEDIUM | Sensitive environment variable access: $HOME Access to sensitive environment variable '$HOME' detected in shell context. Verify this environment variable access is necessary and the value is not exfiltrated. | Static | skills/baoyu-url-to-markdown/SKILL.md:34 | |
| MEDIUM | Unpinned npm dependency version Dependency '@mozilla/readability' is not pinned to an exact version ('^0.6.0'). Pin dependencies to exact versions to reduce drift and supply-chain risk. | Dependencies | skills/baoyu-url-to-markdown/scripts/package.json | |
| LOW | Node lockfile missing package.json is present but no lockfile was found (package-lock.json, pnpm-lock.yaml, or yarn.lock). Commit a lockfile for deterministic dependency resolution. | Dependencies | skills/baoyu-url-to-markdown/scripts/package.json |
