x-mobile-longshot
Render X (Twitter) posts, long articles, and mobile reading pages into mobile-style long screenshots and optional single-page PDFs using Playwright.
This is a legitimate X/Twitter screenshot rendering tool with undocumented shell execution for PDF conversion, but the risk is minimal as file paths are script-generated and Playwright usage is properly documented.

Safe to install
Declare the filesystem WRITE and shell:WRITE permissions in SKILL.md for transparency. Consider moving Python image processing to a Node.js library to eliminate the spawnSync pattern.

Severity Finding Location
Low
Shell execution not declared in SKILL.md Doc Mismatch
The script uses spawnSync to execute python3 with generated code for image processing (PIL/Pillow operations). This shell:WRITE capability is not mentioned in SKILL.md.
const r = spawnSync('python3', ['-c', code], { encoding: 'utf8' });
→ Add 'shell:WRITE' to the declared allowed-tools mapping and document the Python dependency in SKILL.md
 scripts/render_x_longshot.js:77
Low
Filesystem write access not declared Doc Mismatch
The script creates directories and writes PNG/PDF files using Node.js fs module, but filesystem:WRITE is not declared in SKILL.md.
fs.mkdirSync(path.dirname(args.outPng), { recursive: true });
→ Declare filesystem:WRITE permission in SKILL.md since the tool writes output files
 scripts/render_x_longshot.js:83
Info
Python code injection via template strings Obfuscation
Python code is dynamically constructed with interpolated file paths. While inputs are script-generated (not user-supplied), this pattern could be risky if extended.
from PIL import Image
raw = Image.open(r'''${rawPng}''').convert('RGB')
→ Consider using a Node.js image library (e.g., sharp) instead of spawning Python processes to eliminate injection surface

Security Positives

✓ No credential harvesting or sensitive file access
✓ No network exfiltration or C2 communication
✓ No base64 encoding or obfuscation patterns
✓ No curl|bash or remote script execution
✓ Browser automation via Playwright is properly documented
✓ File paths are script-generated, not user-controlled, reducing injection risk
