Scan extension source code and predict Chrome Web Store rejection risks. Generate a clear report.

Reference: https://developer.chrome.com/docs/webstore/troubleshooting

Workflow (Execute This)

Step 1: Ask report format

Ask user: Markdown or HTML report? (default: Markdown)

Step 2: Locate and scan extension

# Find extension root
ls manifest.json wxt.config.ts crxjs.config.ts package.json 2>/dev/null

Step 3: Run all checks

Execute these scans in order (see references/scan-checklist.md for grep patterns):

#	Check	Violation Code	Severity
1	Remote code execution (eval, external scripts)	Blue Argon	CRITICAL
2	Code obfuscation (base64, char encoding)	Red Titanium	CRITICAL
3	Excessive/unused permissions	Purple Potassium	HIGH
4	Missing privacy policy	Purple Lithium	HIGH
5	Missing metadata (icons, description, screenshots)	Yellow Zinc	HIGH
6	Single purpose violation	Red Magnesium	HIGH
7	Deceptive behavior (description ≠ functionality)	Red Nickel	HIGH
8	Insecure data transmission (HTTP)	Purple Copper	HIGH
9	Keyword stuffing in manifest	Yellow Argon	MEDIUM
10	Minimum functionality check	Yellow Potassium	MEDIUM
11	Undisclosed affiliate links	Grey Titanium	MEDIUM
12	Cryptocurrency mining code	Grey Silicon	CRITICAL
13	Copyright circumvention (download helpers)	Blue Zinc	CRITICAL
14	Notification spam patterns	Yellow Nickel	MEDIUM
15	Data collection without consent	Purple Nickel	HIGH

Step 4: Generate report

Output report using template in references/report-template.md.

Report structure per issue:

## Issue: [Name]
- **Severity**: CRITICAL / HIGH / MEDIUM
- **Violation Code**: [Chrome code, e.g. Blue Argon]
- **Root Cause**: [What in your code triggers this]
- **File(s)**: [Exact file paths and line numbers]
- **Solution**: [Step-by-step fix]

Report summary:

| Severity | Count |
|----------|-------|
| CRITICAL | X     |
| HIGH     | X     |
| MEDIUM   | X     |
| PASS     | X     |

Verdict: LIKELY APPROVED / NEEDS FIXES / WILL BE REJECTED

Step 5: Save report

• Markdown: save as extension-review-report.md in project root
• HTML: save as extension-review-report.html with simple, readable styling
