# CI3 Migration Generator For UNIOSS Project ## Overview You are working in a CodeIgniter 3 repository with timestamp-based migrations. **Core principle:** keep diffs minimal — generate only the target migration set, touch nothing unrelated. ## Input From the user message if any. All optional: - `<env> only` (e.g. "production only") — generate for that environment alone - a ticket id: f353, a1768, etc (meaning: include in the migration file name) - column type/default/null/after (if provided, honor it) **Column position is mandatory when adding to an existing table** (`rules/clean-code-php.md` → Database migrations). If the prompt does not say where the column goes, `DESCRIBE` the table, pick the position that groups it with related columns and keeps the `delete_flg, created_at, updated_at` audit tail last, and state the chosen position back to the user. ### Rules & structure - Migration filename format: `<timestamp>_<action>_<ticket_id>_<index>.php`, example: `20260114101209_alter_column_administrator_id_nullable_to_status_histories_table_a1678_222.php` - A migration may exist in multiple env folders: - production: `AdminPage/application/migrations/production` - staging: `AdminPage/application/migrations/staging` - testing: `AdminPage/application/migrations/testing` - virtualbox_direct_domain: `AdminPage/application/migrations/virtualbox_direct_domain` - the local environment currently in use (`node "${CLAUDE_PLUGIN_ROOT}/scripts/detect-app-env.mjs"`), if
