# Database Migration Assistant with Rollback

A PostgreSQL migration assistant that makes schema changes safe and repeatable.  
It provides plan/apply/rollback workflows with drift detection, and exposes stable CLI tools for AI agents to call.  
Designed for production safety: preview first, confirm, then execute.


## Quick Start

```python
from spoon_ai.agents import SpoonReactSkill

agent = SpoonReactSkill(
    name="db_migration_agent",
    skill_paths=["./ai-productivity"],
    scripts_enabled=True
)

result = await agent.run("Plan database migrations for this project")
print(result)

```

## Scripts

| Script | Purpose |
|--------|---------|
| [plan_migrations.py](scripts/plan_migrations.py) | Build a migration plan and detect drift |
| [apply_migrations.py](scripts/apply_migrations.py) | Apply pending up migrations (supports dry-run) |
| [rollback_migrations.py](scripts/rollback_migrations.py) | Roll back the latest migration or to a target version |
| [generate_migration.py](scripts/generate_migration.py) | Generate a new migration SQL template |

## Environment Variables

| Variable | Required | Description |
|----------|----------|-------------|
| `DB_URL` | Yes | PostgreSQL connection string, e.g. postgresql://user:pass@host:5432/db |

## Best Practices

1. Always run `plan` and review the output before `apply`.
2. In production, require explicit confirmation and a recent backup.
3. Treat migration files as append-only; never edit applied migrations.
