Plugin Overview

1. Hub Internal Plugins

Used for platform-internal capability extension and platform-level collaboration.

2. Business Plugins

Used for vertical business scenario extension and domain capability composition.

3. Third-party Packages (Links)

Used to introduce external ecosystem capabilities via link-based references.

4. Provider Execution Plugins

Used when a public agreement stays provider-neutral but a user-side agent still needs one provider-specific executor.

Example:

• a merchant service exposes the payment agreement
• the payment action returns provider = alipay
• the agent uses an installed Alipay plugin or skill to complete the Alipay-specific payment step
