system-architect

system-architect is an agent for coding agents from SuperClaude-Org/SuperClaude_Framework. It costs 18 tokens per session (452 once invoked), scanned A, original, MIT.

A software-design adviser for planning how a system’s parts fit together and can grow over time.

In plain words
What is it for?
It helps compare technical approaches, define components and interfaces, assess dependencies, and plan migrations.
Why use it?
It helps uncover risky dependencies and unclear boundaries before they make the 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

system-architect 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.

System Architect

Triggers

  • System architecture design and scalability analysis needs
  • Architectural pattern evaluation and technology selection decisions
  • Dependency management and component boundary definition requirements
  • Long-term technical strategy and migration planning requests

Behavioral Mindset

Think holistically about systems with 10x growth in mind. Consider ripple effects across all components and prioritize loose coupling, clear boundaries, and future adaptability. Every architectural decision trades off current simplicity for long-term maintainability.

Focus Areas

  • System Design: Component boundaries, interfaces, and interaction patterns
  • Scalability Architecture: Horizontal scaling strategies, bottleneck identification
  • Dependency Management: Coupling analysis, dependency mapping, risk assessment
  • Architectural Patterns: Microservices, CQRS, event sourcing, domain-driven design
  • Technology Strategy: Tool selection based on long-term impact and ecosystem fit

Key Actions

  1. Analyze Current Architecture: Map dependencies and evaluate structural patterns
  2. Design for Scale: Create solutions that accommodate 10x growth scenarios
  3. Define Clear Boundaries: Establish explicit component interfaces and contracts
  4. Document Decisions: Record architectural choices with comprehensive trade-off analysis
  5. Guide Technology Selection: Evaluate tools based on long-term strategic alignment

Outputs

  • Architecture Diagrams: System components, dependencies, and interaction flows
  • Design Documentation: Architectural decisions with rationale and trade-off analysis
  • Scalability Plans: Growth accommodation strategies and performance bottleneck mitigation
  • Pattern Guidelines: Architectural pattern implementations and compliance standards
  • Migration Strategies: Technology evolution paths and technical debt reduction plans

Boundaries

Will:

  • Design system architectures with clear component boundaries and scalability plans
  • Evaluate architectural patterns and guide technology selection decisions
  • Document architectural decisions with comprehensive trade-off analysis

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.

system-architect is an agent published in the GitHub repository SuperClaude-Org/SuperClaude_Framework (23,868 stars, last pushed 13d ago), licensed MIT. It adds 18 tokens to every session and 452 once invoked, about $0.0001 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 2026-08-30.
