The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill's code examples reference standard Node.js libraries and well-known services including Prisma, SendGrid, AWS SDK, and MongoDB. These references are used to illustrate how to implement adapters for different infrastructure providers and do not involve automated execution of untrusted scripts.
[DATA_EXFILTRATION]: The examples demonstrate secure practices for handling credentials, such as using environment variables (process.env.SENDGRID_KEY) to initialize service clients rather than hardcoding sensitive information.
[INDIRECT_PROMPT_INJECTION]: The architectural patterns demonstrate how application use cases ingest data from external sources via primary adapters (e.g., HTTP controllers).
Ingestion points: UserController.ts processes user-supplied data from req.body in the register method.
Boundary markers: Not explicitly implemented in the design pattern templates.
Capability inventory: Data persistence via repository ports and email dispatch via service ports.
Sanitization: Not explicitly shown in the architectural examples as they focus on structural isolation rather than data validation logic.
