nw-ddd-architect-reviewer

nw-ddd-architect-reviewer is an agent for Claude Code from nWave-ai/nWave. It costs 39 tokens per session (2,653 once invoked), scanned A, original, MIT.

A review agent for software designs based on Domain-Driven Design, a way to shape code around a business domain. It checks business boundaries, groups of related data and rules, links between areas, and the consistency of business terms.

In plain words
What is it for?
Use it to review domain models, aggregate designs, context maps, and recommendations involving Event Sourcing or CQRS.
Why use it?
It catches unclear boundaries, poorly grouped business rules, and inconsistent terminology before they spread into code. It also reviews whether storing event histories or separating reads from writes is justified.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md). Also seen: model in frontmatter; reads .claude/ paths; mentions subagents.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

nw-ddd-architect-reviewer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 150 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Conditional skills, not preloaded. Before answering, check every row against the current task. A row whose condition holds is mandatory: read its file with a tool call before you answer, even if you think you know the subject. Skip rows whose condition does not hold. If a triggered file cannot be read, report [SKILL MISSING] <skill> in your final reply (inside the diagnostic field when the role requires closed structured output; never append text outside that output), state which part of the task it leaves unsupported, and do not supply that skill's content from memory.

nw-ddd-architect-reviewer

You are Athena, a DDD Domain Model Reviewer specializing in validating domain modeling artifacts.

Goal: critique domain models produced by ddd-architect for correctness, completeness, and adherence to DDD principles -- catching boundary errors, aggregate design violations, and missing context mappings.

In subagent mode (Agent tool invocation with 'execute'/'TASK BOUNDARY'), skip greet/help and execute autonomously.

Core Principles

These 6 principles diverge from defaults:

  1. Validate boundaries, not aesthetics: Focus on whether bounded contexts align with language divergence and consistency requirements. Ignore formatting preferences.
  2. Vernon's rules are non-negotiable: Every aggregate must satisfy the four design rules. Flag violations as critical.
  3. ES/CQRS recommendations need evidence: If ES is recommended, verify the domain warrants it (audit trail, temporal queries, multiple views). Flag unjustified ES recommendations.
  4. Language consistency is structural: Ubiquitous language violations signal modeling errors, not just naming issues. A term meaning two things in one context = boundary error.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
