ruflo-ddd

Domain-Driven Design scaffolding -- bounded contexts, aggregate roots, domain events, and anti-corruption layers.

Overview

Transforms business domains into well-structured bounded contexts with aggregate roots, value objects, domain events, repositories, and anti-corruption layers. Stores the domain model as a navigable graph in AgentDB with hierarchical nodes and causal edges for context dependencies.

Installation

claude --plugin-dir plugins/ruflo-ddd

Agents

| Agent | Model | Role | |-------|-------|------| | domain-modeler | sonnet | Map domains to bounded contexts, design aggregates with invariants, define domain events, generate ACL interfaces |

Skills

| Skill | Usage | Description | |-------|-------|-------------| | ddd-context | /ddd-context <context-name> | Create a bounded context with standard directory structure | | ddd-aggregate | /ddd-aggregate <context> <aggregate-name> | Scaffold an aggregate root with entity, value objects, repository, events, and test stubs | | ddd-validate | /ddd-validate | Detect cross-context import violations and aggregate invariant issues |

Commands (6 subcommands)

# Context management
ddd context create <name>
ddd context list

# Aggregate scaffolding
ddd aggregate <context> <name>
ddd event <context> <name>

# Validation & visualization
ddd validate                 # Check domain boundary violations
ddd map                      # Visualize context map with relationships

Directory Structure per Context

src/<context-name>/
  domain/
    entities/           # Entities and aggregate root
    value-objects/       # Immutable value objects
    events/             # Domain events
    services/           # Domain services
    repositories/       # Repository interfaces
  application/          # Use cases / application services
  infrastructure/       # Repository implementations, ACL adapters
  index.ts              # Public API of the context

Context Relationships

Detected via import analysis: upstream/downstream, ACL, shared kernel, published language. Boundary violations (direct cross-context imports) are flagged by ddd validate.

Compatibility

• CLI: pinned to @claude-flow/cli v3.6 major+minor.
• Verification: bash plugins/ruflo-ddd/scripts/smoke.sh is the contract.

Namespace coordination

This plugin owns the ddd-patterns AgentDB namespace (kebab-case, follows the convention from ruflo-agentdb ADR-0001 §"Namespace convention"). Reserved namespaces (pattern, claude-memories, default) MUST NOT be shadowed.

ddd-patterns stores reusable bounded-context shapes, aggregate templates, and event vocabularies for cross-project reuse. Accessed via memory_* tools (namespace-routed).

Verification

bash plugins/ruflo-ddd/scripts/smoke.sh
# Expected: "10 passed, 0 failed"

As a mod

Since this version the plugin is also a function-hook mod (ADR-445 pattern; needs Claude Code 2.1.287 or later). It never calls the network or spawns a process, and it only tightens: it can refuse a call, never allow one.

• Guard (default on): refuses domain-model memory writes (ddd-* keys and context:/aggregate: hierarchy edges) that hold a key, token or password. The reason names the kind of secret, never the value.
• /ddd-mod: answered locally, no model turn: status, scan <text> (would the guard refuse this?), and contexts (folders under src/, src/contexts, src/modules with a domain/ layer).
• Status file: .claude-flow/ddd-mod/status.json ({version, updatedMs, guard, blocked}), written at session start and when a call is blocked.
• Option: guard (on | off, default on) in the plugin's userConfig.

Test it: claude plugin test plugins/ruflo-ddd and bash plugins/ruflo-ddd/scripts/smoke.sh.
