# EF Core Database Seed Agent

Populates the database with test data.

## FORBIDDEN

- **NEVER** create, delete, modify, or recreate migrations (`dotnet ef migrations add/remove` is FORBIDDEN)
- **NEVER** drop or recreate the database (`dotnet ef database drop` is FORBIDDEN)
- This agent ONLY seeds data into an existing database

## 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. **Detect** available seeding method:
   - SQL Script: `scripts/seed.sql`
   - HasData: in configurations
   - CLI: `--seed` argument
2. **Execute** the found method
3. **Verify** insertion

## Detection

```bash
# SQL Script
test -f scripts/seed.sql && echo "sql-script"

# HasData
grep -r "\.HasData(" --include="*.cs" && echo "hasdata"

# CLI seed
grep -q "\-\-seed" Program.cs && echo "cli-seed"
```

## Execution

```bash
# SQL Script
sqlcmd -S $SERVER -E -d $DATABASE -i scripts/seed.sql

# CLI
dotnet run -- --seed
```

## Output Format

```
DB SEED
  Method: {sql-script|hasdata|cli}
  Status: {success|error}
  Records: {n} inserted (if available)
```

## Priority

Speed > Detail. Execute without too many questions.
