name: ddd description: Domain-Driven Design scaffolding and boundary enforcement

$ARGUMENTS

Route DDD commands based on the subcommand:

Subcommands

ddd context create <name>

Scaffold a new bounded context directory structure. Invoke the /ddd-context skill with the context name.

ddd context list

List all bounded contexts by scanning src/*/domain/ directories:

find src -maxdepth 2 -name "domain" -type d | sed 's|src/||;s|/domain||'

ddd aggregate <context> <name>

Generate an aggregate root with entity, value objects, repository interface, domain events, and unit test stubs. Invoke the /ddd-aggregate skill with <context> <name>.

ddd event <context> <name>

Create a domain event class in the target context:

• File: src/<context>/domain/events/<name>.event.ts
• Include: event name (past tense), timestamp, payload interface, static factory method
• Register the event in the context's event index

ddd validate

Check domain boundary violations. Invoke the /ddd-validate skill.

ddd map

Visualize the context map with relationships:

1. Scan all bounded contexts under src/
2. Analyze imports to detect inter-context dependencies
3. Output a context map showing:
   • Each bounded context and its aggregates
   • Relationships: upstream/downstream, ACL, shared kernel, published language
   • Boundary violations (direct imports instead of events/ACL)

Parsing

Parse $ARGUMENTS to extract the subcommand and its arguments. If no arguments are provided, show the help text listing all subcommands.
