The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The scripts/check-updates.py maintenance script performs a network request to the official npm registry (registry.npmjs.org) to check for package updates. This is a standard administrative task targeting a well-known service.
[INDIRECT_PROMPT_INJECTION]: The skill documents patterns for building real-time communication systems, which inherently involve processing untrusted data from network clients.
Ingestion points: Real-time event data received through socket.on() listeners as shown in references/03-events-and-acknowledgements.md and other files.
Boundary markers: The documentation recommends using explicit schema validation to separate untrusted inputs from application logic.
Capability inventory: Examples include operations such as database interactions, broadcasting messages, and managing user sessions.
Sanitization: references/11-performance-and-security.md provides specific examples of runtime validation using the Zod library to ensure data integrity and prevent injection.
