In my extension, agents, skills, tools, the MCP environment, permissions, and execution policy are described declaratively and versioned with Git. Configuration therefore gains a diff, history, and rollback path instead of remaining implicit state on a particular machine.

A version should answer three questions: what changed, which tasks it is recommended for, and on which runs—and with which metrics—it demonstrated an improvement. Then arguments about prompts and skills become engineering discussions instead of matters of taste.
