# CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

## Project Overview

ROMFASTSQL is an infrastructure and database management project for ROMFAST, featuring:
- Proxmox virtualization cluster (3 nodes: pve1, pvemini, pveelite)
- Oracle Database XE 21c with migration support from Oracle 10g
- AI chatbot system (Flowise + Claude)
- Disaster recovery infrastructure

## SQL Migration Conventions

When writing Oracle migration scripts, follow the naming convention:
```
ff_YYYY_MM_DD_##_TYPE.sql
```
Where TYPE is: DDL, DML, VIEW, PACK, TRIG, etc.

Always reference `system_instructions/system_prompt.md` for:
- Oracle 10g compatibility requirements
- PACK_MIGRARE package usage
- Migration script patterns and examples

## Custom Claude Code Commands

- `/ultimate_validate_command` - Generate comprehensive validation commands
- `/plan-handover` - Save implementation plan for session handover
- `/branch-plan-handover` - Create branch and save plan
- `/context-handover` - Save context for next session

## Git Workflow

- Remote: `http://gitea:3000/romfast/ROMFASTSQL.git`
- Main branch: `master`
- Feature branches merged directly to master
