Helps users configure mirrord.json for database branching, enabling isolated database copies for safe development and testing. Use when the user wants to set up MySQL, MariaDB, PostgreSQL, MSSQL, MongoDB, Redis, DynamoDB, ClickHouse, Google Spanner, Amazon S3, turbopuffer, or generic branches, configure copy modes, connection sources, schema migrations, IAM authentication, or manage database branches.

# Mirrord DB Branching Skill

## Purpose

Generate and validate `mirrord.json` configurations for database branching:
- **Generate** valid `db_branches` configs from natural language descriptions
- **Explain** copy modes, connection sources, schema migrations, IAM authentication, and branch management
- **Validate** user-provided configs against schema requirements
- **Troubleshoot** common DB branching issues

DB branching is a **Team / Enterprise** feature. It spins up an isolated branch of a remote database so developers (and AI agents) can run schema changes, migrations, and experiments without affecting teammates or shared environments.
