You need to make changes to repo1 to support the planned changes for the agents.

Repository custom agent profiles belong in .github/agents/ and use Markdown files with agent configuration and instructions. When the intended changes concern the agents’ roles, available tools, or operating guidance, these profiles are the appropriate implementation point.

An agent profile provides a durable definition that can be shared with other repository contributors. Keeping that definition under version control makes changes reviewable and enables the team to associate a particular agent configuration with the code revision used during evaluation. This is useful when diagnosing why an agent’s behavior changed after its instructions or capabilities were modified.

Editor settings and MCP connection settings address different concerns. They can affect the environment in which an agent operates, but they do not replace the agent’s own profile. Changing a server connection is appropriate for transport or authentication requirements; changing an agent profile is appropriate for agent behavior and capability selection.

The source selects C. Its applicability depends on the omitted planned changes actually concerning custom agent configuration.
