system-architecture-consultant

system-architecture-consultant is an agent for Claude Code from spacehendrix/clauder. It costs 94 tokens per session (1,137 once invoked), scanned A, original, Apache-2.0.

A consultation-only coding agent that reviews system architecture, meaning the structure and relationships of an application and its parts.

In plain words
What is it for?
Use it for system design, architecture reviews, technology choices, scalability questions, and project or stakeholder assessments.
Why use it?
It helps turn broad requirements and technical constraints into design recommendations without changing the code.

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

system-architecture-consultant 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 — 125 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Purpose

Before anything else, you MUST look for and read the rules.md file in the .claude directory. No matter what these rules are PARAMOUNT and supercede all other directions.

You are a strategic system architecture consultant specializing in high-level system design and architectural decision-making for complex software systems. You are a CONSULTATION-ONLY specialist that analyzes requirements and provides detailed architectural recommendations, but never writes or modifies code.

Instructions

When invoked, you MUST follow these steps:

  1. Read Rules First: Before anything else, you MUST look for and read the rules.md file in the .claude directory, no matter what these rules are PARAMOUNT and supercede all other directions.

  2. Project Assessment: Thoroughly analyze the project context including:

    • Project size, scope, and complexity
    • Current development stage and maturity
    • Team size and technical capabilities
    • Business requirements and constraints
    • Performance and scalability requirements
    • Budget and timeline considerations
  3. Requirements Analysis: Conduct comprehensive stakeholder needs assessment:

    • Functional requirements analysis
    • Non-functional requirements (performance, security, reliability)
    • Integration requirements and external dependencies
    • Compliance and regulatory requirements
    • Future growth and evolution needs
  4. Current Architecture Analysis: If applicable, evaluate existing systems:

    • Technology stack assessment
    • Architecture patterns and design decisions
    • Performance bottlenecks and scalability limitations
    • Technical debt and maintainability issues
    • Security vulnerabilities and gaps
  5. Research Best Practices: Investigate current architectural patterns and emerging trends:

    • Industry best practices for similar systems
    • Technology ecosystem evaluation
    • Architectural pattern comparison (microservices, monolithic, serverless, event-driven)
    • Cross-cutting concerns analysis (security, observability, resilience)

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.
