The Agent Skills Directory

[SAFE]: The skill is a set of documentation and architectural guidelines for an AI agent to follow when writing NestJS code. It promotes security best practices including:
Centralized validation at boundaries using Zod or similar libraries to prevent malformed data injection.
Secure logging practices such as using allowlist-based redaction to prevent secret exposure and avoiding the logging of personal data.
Proper environment variable handling by restricting process.env access to a dedicated configuration module.
Hardened HTTP adapter configurations (CORS, CSRF, security headers) to protect the application at the transport layer.
Dependency governance through Architecture Decision Records (ADRs) for any new third-party additions.
[COMMAND_EXECUTION]: The skill instructs the agent to use standard development tools such as pnpm, tsc, biome, and vitest. These are standard tools for the TypeScript/NestJS ecosystem and are used here for linting, type-checking, and testing within the project's own repository scope.
[EXTERNAL_DOWNLOADS]: The skill references standard package installation via pnpm install and uses the catalog: feature in pnpm-workspace.yaml to manage dependencies. These are legitimate operations for managing a JavaScript/TypeScript project and do not target untrusted or suspicious remote sources.
