Risk Level: SAFEINDIRECT_PROMPT_INJECTION
Full Analysis
- [INDIRECT_PROMPT_INJECTION]: The skill identifies a potential surface for indirect prompt injection when processing data returned from the MCP server.
- Ingestion points: The agent is instructed to process
output_components(which may contain text or suggestions) from thegenerate_screen_from_texttool response (SKILL.md). - Boundary markers: No specific delimiters are defined for the tool's output data within the instructions.
- Capability inventory: The skill utilizes the
mcp__stitchtoolset, which includes capabilities for screen generation, project listing, and design system application. - Sanitization: The instructions explicitly mandate a human-in-the-loop verification process. The agent is strictly forbidden from auto-accepting suggestions and must present them to the user for explicit approval (SKILL.md, "Handling output_components").
- [SAFE]: No malicious patterns, obfuscation, or unauthorized data exfiltration attempts were detected. The skill is instructional in nature and facilitates the use of a well-known UI design service (Google Stitch). The polling logic provided is a standard functional pattern for managing high-latency API operations and does not constitute a malicious time-delayed trigger.
