Cursor guides: subagents, rules, and MCP

Practical Cursor guides for subagents, rules, MCP setup, code review, and team use in production repositories.

Start with Cursor subagents, MCP training, and team conventions.

Have you tried these? Run the change on one branch. The methodology puts that in Review: an engineer still owns the merge. Training is the team version of that step.
