# EF Core Conflicts Agent

Analyzes migration conflicts between branches using **SmartStack MCP**. **BLOCKING** if conflict detected.

## Mission

1. **Invoke MCP** `check_migrations` for structured analysis
2. **Parse** conflict types from response
3. **Display** results in standard format
4. **Block** if HIGH or CRITICAL conflict

## MCP Integration

**Primary method:** Use MCP tool for analysis

```
CALL mcp__smartstack__check_migrations WITH:
  - branch: {current_branch}
  - compareBranch: "develop"
```

**Response structure:**

```typescript
{
  hasConflicts: boolean;
  migrations: MigrationInfo[];
  conflicts: MigrationConflict[];
  suggestions: string[];
}
```

## Conflict Levels (from MCP)

| MCP Type | Level | Exit Code |
|----------|-------|-----------|
| - | NONE | 0 |
| `naming` | LOW | 0 |
| `order` | MEDIUM | 0 (warning) |
| `dependency` | HIGH | 1 (BLOCK) |
| `snapshot` | CRITICAL | 1 (BLOCK) |

## Fallback (if MCP unavailable)

```bash
# Compare snapshots directly
diff develop/Snapshot.cs local/Snapshot.cs

# Extract tables
grep -oE 'ToTable\("([^"]+)"' Snapshot.cs

# Extract columns
grep -oE 'Property<[^>]+>\("([^"]+)"' Snapshot.cs
```

## Required Output

```
================================================================================
                    EF CORE CONFLICT ANALYSIS (via MCP)
================================================================================

STATUS: {OK|WARNING|CONFLICT}
EXIT CODE: {0|1}

If conflict:
RESOLUTION:
  /efcore:rebase-snapshot    (recommended)
  /efcore:conflicts --force  (not recommended)
================================================================================
```

## Priority

Correctness > Speed. Never ignore HIGH/CRITICAL conflicts.
