html-markdown-converter
Convert HTML↔Markdown for web clipping, clean notes, and batch content migration
A legitimate HTML↔Markdown converter with minor doc-to-code gaps and benign external URL references, but no malicious behavior detected.

✓
Safe to install
Declare shell execution (pandoc engine) and filesystem WRITE permissions in SKILL.md. Consider removing unrelated external URLs from documentation.

Severity Finding Location
Medium
Shell execution not declared in SKILL.md Doc Mismatch
The html_to_markdown.mjs script uses node:child_process spawn to execute 'pandoc' when --engine pandoc or --engine best is selected. SKILL.md does not mention shell execution, the pandoc binary requirement, or the spawn behavior.
const child = spawn('pandoc', ['-f', 'html', '-t', to], { stdio: ['pipe', 'pipe', 'pipe'] });
→ Add --engine pandoc notes to SKILL.md and declare shell:WRITE permission in the allowed tools mapping. Document pandoc as an optional external dependency.
 scripts/html_to_markdown.mjs:271
Low
Unrelated external URLs in SKILL.md Doc Mismatch
SKILL.md references two automotive-data websites (jisuapi.com, jisuepc.com) with no code-level connection. These appear in a 'Related sites' section and serve no functional purpose in a converter tool. Could indicate SEO promotion or an attempt to associate the skill with unrelated services.
https://jisuapi.com / https://jisuepc.com
→ Remove unrelated external URLs from SKILL.md or clarify their purpose. External URLs without functional code integration reduce skill focus and could be a social engineering signal.
 SKILL.md:129
Low
Allowed tools mapping not declared Doc Mismatch
SKILL.md does not include an allowed tools / capability declaration section. Users cannot determine what permissions the skill requires. The skill uses filesystem:WRITE (file output), network:READ (URL fetching), and shell:WRITE (pandoc) without any declaration.
No 'allowed-tools' or 'permissions' section present in SKILL.md
→ Add a brief permissions/capabilities section to SKILL.md documenting filesystem (read+write), network (read), and shell (write via pandoc) usage.
 SKILL.md:1
Low
Unpinned dependency versions Supply Chain
package.json uses caret (^) ranges for all dependencies (e.g., '^0.5.0', '^14.1.0'). While not inherently malicious, this allows silent major/minor updates that could introduce behavioral changes or vulnerabilities.
"jsdom": "^26.0.0"
→ Pin exact versions (remove ^) in package.json for reproducible builds, especially in a skill distribution context.

Security Positives

✓ No credential theft: No access to ~/.ssh, ~/.aws, .env, or environment variable iteration for secrets
✓ No data exfiltration: No POST requests, no external data sending, no C2 communication patterns
✓ No obfuscation: All code is readable ESM modules with clear logic flow
✓ No reverse shell or RCE: spawn() only used for pandoc binary (a legitimate CLI tool)
✓ No base64 or dynamic code execution: No eval(), Function(), or atob() patterns
✓ No hidden instructions: No HTML comments with embedded instructions, no prompt injection detected
✓ No supply-chain IOCs: All npm dependencies are from well-known, established packages
✓ No persistence mechanisms: No cron jobs, startup scripts, or backdoor installation
✓ Legitimate use of subprocess: pandoc engine is standard CLI tool for HTML↔Markdown conversion
