What is the primary purpose of the WebSpec Subdomain Architecture skill?

It provides standardized patterns and best practices for ensuring secure communication and isolation between different WebSpec services by leveraging subdomains and strict scoping rules.

Why are root domain cookies forbidden in this architecture?

Root domain cookies are forbidden to prevent cross-service token theft and maintain strict security boundaries, ensuring that cookies set on one subdomain cannot be accessed by another.

What is JWT audience binding in the context of WebSpec?

Every JWT must include an 'aud' claim matching the specific subdomain it is intended for, preventing token replay attacks across different services.

How does the local.gimme.tools bridge maintain security?

It uses an authenticated WebSocket tunnel, validates session tokens, checks device binding, and routes requests through local Unix sockets to prevent network exposure.

Security & Testing

Implements secure subdomain isolation, strict cookie scoping, and token-bound communication patterns for WebSpec environments.

The WebSpec Subdomain Architecture skill provides a comprehensive framework for managing security boundaries within the WebSpec ecosystem. It leverages the browser's same-origin policy to create natural isolation between services like auth, API, and local bridges. By enforcing strict cookie attributes, JWT audience binding, and secure WebSocket tunneling via local.gimme.tools, it ensures that session data and local resources remain protected. This skill is essential for developers configuring multi-service architectures that require high-trust local-to-cloud communication and robust cross-origin protection.
