Ddd Aggregate

Scaffold a complete aggregate root inside a bounded context.

Parse $ARGUMENTS as <context-name> <aggregate-name> (both kebab-case). The context must already exist under src/.

Steps

1. Validate: Confirm src/<context>/domain/ exists. If not, suggest running /ddd-context <context> first.

1. Pre-task hook: npx @claude-flow/cli@latest hooks pre-task --description "DDD aggregate: <aggregate-name> in <context>"

1. Create aggregate root entity:

• File: src/<context>/domain/entities/<aggregate-name>.entity.ts
• Include: unique ID field, constructor with invariant validation, domain methods that enforce business rules, equals() based on identity
• Export a TypeScript class extending or implementing a base AggregateRoot interface

1. Create value objects:

• File: src/<context>/domain/value-objects/<aggregate-name>-id.value-object.ts
• Include: immutable ID value object with factory method and validation
• Add additional value objects as properties of the aggregate suggest them

1. Create repository interface:

• File: src/<context>/domain/repositories/<aggregate-name>.repository.ts
• Include: findById, save, delete methods
• Use the aggregate root and its ID value object as types
• This is an interface only -- no implementation (infrastructure concern)

1. Create domain events:

• File: src/<context>/domain/events/<aggregate-name>-created.event.ts
• File: src/<context>/domain/events/<aggregate-name>-updated.event.ts
• Include: event name (past tense), timestamp, aggregate ID, payload

1. Create unit test stubs:

• File: src/<context>/domain/entities/<aggregate-name>.entity.test.ts
• Include: test cases for construction invariants, domain methods, equality
• Use describe/it with should [behavior] when [condition] names

1. Update barrel exports: Add new files to the relevant index.ts barrel files.

1. Store in domain model graph: `` mcp__plugin_ruflo-core_ruflo__agentdb_hierarchical-store --parent "context:<context>" --child "aggregate:<aggregate-name>" --relation "contains" mcp__plugin_ruflo-core_ruflo__memory_store --key "ddd-aggregate-<context>-<aggregate-name>" --value "AGGREGATE_SUMMARY" --namespace tasks ``

1. Post-task hook: npx @claude-flow/cli@latest hooks post-task --task-id "ddd-aggregate-<aggregate-name>" --success true --train-neural true
