Beyond the built-ins and your own Agent Creator packages, you can import packages built by others. Imported packages appear in the Marketplace under the Community tab and work like any specialization.
Import methods
From the Marketplace’s Add Agent Package modal:
A success or failure badge reports the result.
What is in a package
A package is a set of skills: markdown files defining a name, a description, and a procedure each. The package page in the Marketplace shows the full skill grid and source metadata (the GitHub link when available, otherwise “Source not listed”).
Some community packages require an API key for the services they call; the package page includes a key section with save, test, and clear controls where that applies.
Trust and safety
Skills are instructions your agents follow, with the agent’s permissions. Only install packages from sources you trust, and skim the skill descriptions before granting the agent broad permissions or MCP tools.
Removing a package
Select the package in the Marketplace sidebar and remove it from its detail view. Agents already created from it keep their configuration but lose access to skills the package provided.
