Does this skill support Express.js?

Yes, it includes specific code patterns and middleware templates for implementing webhook endpoints using Express.js and raw body parsing.

How does it protect against replay attacks?

The skill implements a cryptographic timestamp verification check that automatically rejects incoming webhook notifications older than five minutes.

Do I need a specific API secret to use this?

Yes, you must configure your VASTAI_WEBHOOK_SECRET in your environment variables to allow the skill to validate incoming signatures correctly.

Can I use this to ensure idempotency?

Yes, it provides a dedicated Redis-based pattern to track event IDs, ensuring that each Vast.ai notification is processed exactly once.

What Vast.ai event types are supported?

The skill provides extensible patterns for resource.created, resource.updated, and resource.deleted events, which can be customized for any Vast.ai notification type.
