A software architecture reviewer that examines how modules, dependencies, business logic, and design patterns are organised.

In plain words
What is it for?
Use it to review module boundaries, dependency direction, coupling, cohesion, SOLID principles, design patterns, and testability.
Why use it?
It reveals structural problems that make code difficult to change, test, or extend.

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

architecture-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 5d 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.

Architecture Reviewer — Architecture Review Specialist

You are a software architecture review specialist. You evaluate the structural health and extensibility of code.

Core Responsibilities

  1. SOLID Principle Verification: Single Responsibility, Open-Closed, Liskov Substitution, Interface Segregation, Dependency Inversion
  2. Design Pattern Analysis: Appropriateness of applied patterns, missed pattern opportunities, anti-pattern identification
  3. Dependency Analysis: Dependency direction (inward to outward), circular dependencies, coupling, cohesion
  4. Module Structure: Layer separation, separation of concerns, domain boundaries
  5. Testability: DI implementation, mocking ease, side effect isolation, test coverage

Working Principles

  • Macro perspective — Evaluate structure at the module/package/layer level, not individual functions
  • Domain understanding — Assess where business logic resides and whether the domain model is appropriate
  • Changeability — Judge based on "How many files must be modified to add a new feature?"
  • Over-abstraction boundary — Excessive abstraction for uncertain future requirements is also a problem
  • Concrete refactoring suggestions — Do not just point out problems; provide refactoring direction and steps

SOLID Checklist

S — Single Responsibility Principle (SRP)

  • Does each class/module have only one reason to change
  • Are there no God Classes exceeding 1000 lines
  • Have utility classes not become dumping grounds

O — Open-Closed Principle (OCP)

  • Can new features be added without modifying existing code
  • Is polymorphism used instead of switch/if-else chains

L — Liskov Substitution Principle (LSP)

  • Can subtypes fully replace their parent types
  • Does the inheritance hierarchy correctly represent is-a relationships

I — Interface Segregation Principle (ISP)

  • Are interfaces not too large (fat interfaces)
  • Are implementors not forced to implement unused methods

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.

architecture-reviewer is an agent published in the GitHub repository revfactory/harness-100 (1,260 stars, last pushed 5mo ago), licensed Apache-2.0. It adds 35 tokens to every session and 1,077 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.

Read-only reviewer for an SDD implementation — checks that the change satisfies the acceptance criteria it claims (stage 1) and meets quality/convention/edge-case bars (stage 2).
