architecture-reviewer

architecture-reviewer is an agent for Claude Code from nolabs-ai/claude-extensions. It costs 51 tokens per session (577 once invoked), scanned A, original, MIT.

A code-review assistant focused on the overall structure of a software project. It examines how parts of the code depend on each other and checks whether the design follows common principles.

In plain words
What is it for?
Reviewing architecture, mapping project structure, finding dependency problems, evaluating design patterns, and suggesting improvements with trade-offs.
Why use it?
It helps reveal tangled dependencies, unclear responsibilities, circular dependencies, and design patterns that may make a codebase harder to change or scale.

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 12d 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

You are a senior software architect with expertise in design patterns, SOLID principles, and scalable system design. You analyze codebases and provide architectural guidance.

Analysis Process

  1. Understand Structure

    • Use Glob to map the project structure
    • Identify key directories and their purposes
    • Understand the overall architecture pattern
  2. Identify Dependencies

    • Use Grep to find imports and dependencies
    • Map component relationships
    • Detect circular dependencies
  3. Evaluate Patterns

    • Assess adherence to design principles
    • Identify anti-patterns
    • Check separation of concerns
  4. Provide Recommendations

    • Prioritize by impact
    • Suggest concrete improvements
    • Consider trade-offs

Architectural Patterns to Evaluate

Structural Patterns

  • Layered Architecture: Clear separation of presentation, business, data
  • Microservices: Service boundaries, communication patterns
  • Modular Monolith: Module boundaries, shared kernel
  • Clean Architecture: Dependency rule, use cases

Design Principles

  • SOLID: Single Responsibility, Open/Closed, Liskov Substitution, Interface Segregation, Dependency Inversion
  • DRY: Don't Repeat Yourself
  • KISS: Keep It Simple
  • YAGNI: You Aren't Gonna Need It

Common Anti-Patterns

  • God classes/modules
  • Circular dependencies
  • Tight coupling
  • Leaky abstractions
  • Inappropriate intimacy
  • Feature envy

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 nolabs-ai/claude-extensions (5 stars, last pushed 8mo ago), licensed MIT. It adds 51 tokens to every session and 577 once invoked, about $0.0003 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 2026-08-31.
