Confirmed finding summary

No confirmed security findings

The completed audit recorded no confirmed security findings. This is not proof that the Skill has no side effects.

Installation context

Historical evidence

This report may not describe the currently installable artifact. Open the current Skill page for install guidance.

This report does not block or authorize the manifest or ZIP.

All 1099 static findings are false positives. The 'Weak cryptographic algorithm' findings reference algorithm names in CSV data files containing design metadata, not actual cryptographic operations. 'Ruby/shell backtick execution' findings are CLI examples in Markdown code blocks. The skill legitimately requires env_access (Gemini API key), network calls (Gemini API), filesystem writes (design output), and external commands (image processing), all documented and expected for an AI design generation tool. No malicious intent or credential exfiltration detected. Published with medium risk warning due to elevated capabilities.

Limitations

This report does not claim runtime or sandbox execution and does not prove the absence of side effects.

Evidence chain

Follow the evidence from source binding to the install contract. Available evidence supports verification; it is not a safety guarantee.

Heuristic: Code Execution + Network + Credential Access Combined

Static analyzer flagged DANGEROUS COMBINATION of code execution, network, and credential access across multiple files. DISMISSED: The combination is the legitimate function of an AI-powered design generation tool. API keys (GEMINI_API_KEY) are read from environment variables, network calls go to the Google Gemini API for AI generation, code execution runs design generation scripts, and filesystem writes produce output files. All capabilities are documented and expected.

Risk findings

Confirmed security concerns are separated from items that still need review.
