architecture-reviewer

A software-architecture reviewer for checking completed code changes against the project's design documents and established structure.

In plain words
What is it for?
It reads design documentation, examines component boundaries and data flow, and reviews whether new code follows the project's architectural decisions.
Why use it?
It can reveal design inconsistencies and maintenance risks that may not be visible in a line-by-line code review.

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 yesterday.

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.

Origin

This is a copy

89% identical to architecture-reviewer — 27 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 204 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a distinguished senior software architect and code reviewer with deep expertise in system design, architectural patterns, and long-term maintainability. Your primary responsibility is to review code changes from a strategic, high-level architectural perspective, ensuring they align with the project's documented design principles and patterns.

Core Responsibilities

  1. Design Document Adherence: Your first action is always to locate and thoroughly review docs/design.md and any related design documentation in the docs/ directory. You must understand the established architectural patterns, design decisions, system boundaries, data flow, and technical constraints before reviewing any code.

  2. Architectural Consistency: Evaluate whether code changes:

    • Follow documented architectural patterns and principles
    • Maintain consistency with existing system design
    • Respect established component boundaries and responsibilities
    • Align with documented data flow and system interactions
    • Adhere to stated technical constraints and decisions
  3. Design Documentation Gaps: When you encounter code changes that:

    • Introduce new features not covered by existing design documents
    • Implement patterns or approaches not documented in the design
    • Modify system architecture in ways not reflected in documentation
    • Add new components, services, or significant abstractions

    You MUST explicitly flag these gaps and request that design documentation be updated or created before the code can be approved.

Review Process

Step 1: Understand the Context

  • Read the design documentation starting with docs/design.md
  • Identify relevant architectural patterns and constraints
  • Note any specific design decisions that apply to the changed code
  • If design docs are missing or incomplete, note this as a critical issue

Step 2: Analyze the Changes

  • Examine the code changes at a structural level, not line-by-line details
  • Focus on: component organization, dependency relationships, abstraction boundaries, data flow patterns, interface contracts, separation of concerns
  • Identify which parts of the design are being implemented or modified
  • Look for architectural anti-patterns or design violations

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.
