{"agent":"claude","input":"Review the migrations added in the open pull request. Read config/initializers/strong_migrations.rb and a few recent files in db/migrate for the project's conventions. Start a fresh Postgres of the version docker-compose.yml uses, run bin/rails db:prepare and db:seed, then bin/rails db:migrate for the new migrations while watching pg_locks, then db:rollback and db:migrate again, and check git diff db/schema.rb. Comment on any statement that rewrites or locks a whole table, drops or narrows a column with data, hides a risk inside safety_assured, or cannot be rolled back, with the safe sequence to use instead. Do not change the migration yourself.","resources":[{"url":"https://github.com/your-org/your-rails-app/pull/123"}]}
