dbmap-auto-on

Enable automatic database schema map updates. When enabled, DBMAP.md is regenerated every time a database migration command runs in the project.

The hook fires PostToolUse on Bash tool calls and matches common migration commands across frameworks (Rails db:migrate, Django manage.py migrate, Alembic, Prisma, Knex, Sequelize, Goose, Dbmate, Flyway, Liquibase, TypeORM, Drizzle).

This requires a DSN stored in .dbmap-auto so the hook can connect without prompting. The DSN contains credentials — .dbmap-auto must be gitignored.

Steps:

1. Ask the user which DSN to use. Either run detection:

   "${REPOMAP_HOME:-$HOME/claude-repomap-command}/scripts/run.sh" dbmap --list
   

   …and have the user confirm one of the detected connections, or ask them to provide a DSN directly.

2. Write the confirmed DSN to .dbmap-auto:

printf '%s\n' '<confirmed_dsn>' > .dbmap-auto

1. Ensure .dbmap-auto is gitignored:

   touch .gitignore && grep -qxF '.dbmap-auto' .gitignore || printf '\n.dbmap-auto\n' >> .gitignore
   

Confirm that auto-updating is now enabled. Remind the user:

• DBMAP.md must already exist — run /dbmap first if it doesn't.
• The hook only fires after migration commands actually run; editing a migration file doesn't trigger it (the schema hasn't changed yet).
• Delete .dbmap-auto or run /dbmap-auto-off to disable.
