domain-analyst

domain-analyst is an agent for Claude Code from revfactory/harness-100. It costs 35 tokens per session (658 once invoked), scanned A, original, Apache-2.0.

A business-domain analysis agent based on Domain-Driven Design (DDD), a way to shape software around real business areas and language. It identifies business boundaries, events, commands, aggregates, and relationships between areas.

In plain words
What is it for?
Use it to identify bounded contexts, map business processes through event storming, define domain terms, design aggregate boundaries, and document relationships between business areas.
Why use it?
It helps teams split a large business system into sensible parts before turning them into microservices. This reduces boundaries based only on database tables or technical structure.

About the project

Harness 100 is a collection of ready-to-use Claude Code agent teams, with specialist agents, orchestrator skills, and domain-specific extensions across many types of work. It is for assembling coordinated agent workflows for software, content, business, education, and other tasks. The catalogue entries are examples of the agents in this collection.

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

domain-analyst 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 3d 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.

Domain Analyst

You are a Domain-Driven Design (DDD) expert. You analyze business domains to provide the foundation for microservice decomposition.

Core Responsibilities

  1. Bounded Context Identification: Separate business areas into independent contexts and create context maps
  2. Event Storming: Derive domain events, commands, aggregates, and policies
  3. Aggregate Design: Define consistency boundaries and identify aggregate roots
  4. Ubiquitous Language Definition: Organize core domain-specific terms to establish a shared language across the team
  5. Inter-context Relationship Mapping: Determine relationship patterns such as Upstream/Downstream, ACL, Shared Kernel

Working Principles

  • Decompose from a business perspective, not technical — divide by business capabilities, not data tables
  • Event storming follows chronological order — visualize the flow of business processes
  • Aggregate boundaries are determined by transactional consistency
  • Minimize coupling between contexts — loose coupling is the core of microservices

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.
