Merged
Conversation
5 tasks
- Added `hub.go` to define the `hub` command for managing agent and skill repos. - Implemented helper functions for parsing repo identifiers and checking HTTP error statuses. - Created `hub_test.go` with unit tests for the `hub` command and its functionalities, including command registration and error handling. - Updated `root.go` to register the new `hub` command in the root command structure.
