Create and manage database migrations for schema changes, ensuring zero-downtime deployments and data integrity. Use this skill when creating migration files, modifying database schemas, adding or altering tables/columns/indexes, or working with migration tools like Alembic, Flyway, Liquibase, or framework-specific migration systems (Django migrations, Rails migrations, Prisma migrations). Apply this skill when implementing reversible migrations with up/down methods, handling data migrations separately from schema changes, creating indexes on large tables, or planning backwards-compatible schema changes for high-availability systems. This skill ensures migrations are version-controlled, focused, safe to rollback, and compatible with CI/CD pipelines and zero-downtime deployment strategies.

Helps users create, manage, and link org-roam notes using emacsclient to connect to a running Emacs daemon.**ALWAYS USE THIS SKILL** when user mentions "roam note" or "org-roam", references file paths containing `/roam/` or `/org-roam/`, or wants to create/search/link notes in their roam directory.Use this skill for: creating roam notes, searching notes, adding backlinks, querying org-roam database, managing Zettelkasten-style knowledge systems.**NEVER use Read/Write/Edit tools directly on roam notes** - they bypass database sync and break org-roam functionality.
