# EF Core Database Deploy Agent

Applies pending migrations to the local database.

## FORBIDDEN

- **NEVER** create, delete, modify, or recreate migrations (`dotnet ef migrations add/remove` is FORBIDDEN)
- **NEVER** modify `.cs` files in the Migrations directory
- This agent ONLY runs `dotnet ef database update` to apply existing migrations

## WSL Preflight (MANDATORY - run BEFORE any git command)

```bash
# Repair worktree .git file if Windows path detected under WSL
if [ -f .git ] && grep -q '^gitdir: [A-Za-z]:' .git 2>/dev/null && grep -qi microsoft /proc/version 2>/dev/null; then
  p=$(sed 's/^gitdir: //' .git | tr -d '\r\n'); d=$(echo "${p:0:1}" | tr A-Z a-z); r="${p:2}"; r="${r//\\//}"
  printf 'gitdir: %s\n' "$(realpath -m --relative-to="$(pwd)" "/mnt/$d$r")" > .git
  echo "Worktree .git path repaired for WSL"
fi
```

## Workflow

1. **Verify** appsettings.Local.json exists
2. **Detect** available DbContexts (CoreDbContext, ExtensionsDbContext)
3. **Count** pending migrations per context
4. **Apply** migrations in order: Core first, then Extensions
5. **Confirm** success

## Dual DbContext Order

**IMPORTANT:** Migrations must be applied in order:
1. **CoreDbContext** first (SmartStack platform tables)
2. **ExtensionsDbContext** second (client tables that may reference Core)

This ensures FK references from Extensions to Core work correctly.

## Commands

```bash
# Verify config
test -f appsettings.Local.json && echo "OK" || echo "MISSING"

# Apply Core migrations first
dotnet ef database update --context CoreDbContext --verbose

# Then apply Extensions migrations
dotnet ef database update --context ExtensionsDbContext --verbose
```

## Output Format

```
DB DEPLOY
  Config: appsettings.Local.json

  CORE CONTEXT
    Applied: {n} migration(s)
    Status: {success|error}

  EXTENSIONS CONTEXT
    Applied: {n} migration(s)
    Status: {success|error|skipped}
```

## Error Handling

If connection error:
```
ERROR: Database connection failed
  → Verify SQL Server is running
  → Verify appsettings.Local.json
  → /efcore db-reset to create DB
```

## Priority

Speed > Verbosity. Minimal output if successful.
