ABP Data Seeder Contributor Generator

Generates production-ready data seeder contributors following this project's conventions and ABP Framework best practices. This skill creates classes that implement IDataSeedContributor for seeding initial, reference, or lookup data into the database.

Key feature: Auto-detects project structure, existing entities, namespaces, and seeder patterns before generating — no manual configuration needed.

When to Use

• Adding initial lookup/reference data (e.g., categories, types, enumerations)
• Seeding default configuration or system data
• Setting up multi-tenant default data
• Creating data migrations with seed content
• Populating test/development data
• Any data that should exist when the application first runs or when a new tenant is provisioned

Step 0 — Auto-Detect Project Structure

Do this automatically before asking the user anything. Never ask what you can detect.

0.1 Find Solution and Project Name

# Find solution file
find . -name "*.sln" | head -3

# Extract project/solution name
basename $(find . -name "*.sln" | head -1) .sln

# Find all .csproj files and classify layers
find . -name "*.csproj" | sort
# *.Domain.csproj                  → Domain layer
# *.Domain.Shared.csproj           → Domain Shared (constants, enums)
# *.Application.csproj             → Application layer
# *.EntityFrameworkCore.csproj     → EF Core layer
# *.DbMigrator.csproj              → DbMigrator (tenant-aware seeders go here)
# *.HttpApi.Host.csproj            → Host layer

0.2 Detect Root Namespace

# Extract namespace from any existing AppService or entity
grep -m1 "^namespace " $(find . -name "*AppService.cs" ! -path "*/bin/*" | head -1) 2>/dev/null

# Fallback: read from .csproj RootNamespace
grep "RootNamespace" $(find . -name "*.Domain.csproj" | head -1) 2>/dev/null

0.3 Detect Existing Seeder Patterns

# Find all existing seeders — most important step
find . -name "*DataSeed*" -o -name "*SeedContributor*" -o -name "*SeederContributor*" \
  | grep "\.cs$" ! -path "*/bin/*" ! -path "*/obj/*" | head -10

# Read EVERY existing seeder found — learn the exact pattern used
# view each file found above
