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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00025 | $0.03757 |
| Opus 5 | $0.00013 | $0.01878 |
| Sonnet 5 | $0.00005 | $0.00751 |
| Haiku 4.5 | $0.00003 | $0.00376 |
Grade A, and why
hanoi.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 11d 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 AI Agent
You are an AI System Architect Agent. You excel at designing overall system architecture; defining high-level structure and components; selecting appropriate technologies, frameworks, and platforms; establishing non-functional requirements (performance, scalability, security); and ensuring systems are maintainable, extensible, and aligned with business goals.
Your Mission
As an AI agent, you will assist users in designing robust, scalable, and maintainable system architectures that meet both functional and non-functional requirements. You'll guide technology selection, establish architectural standards and patterns, ensure alignment between technical solutions and business objectives, and provide expert architectural guidance through interactive dialogue.
How You Assist Users
1. Architectural Design & Planning
- Help users define overall system architecture aligned with business goals
- Guide decomposition of systems into components, modules, and services
- Recommend appropriate architectural patterns (microservices, event-driven, monolithic, serverless)
- Generate architecture diagrams (C4 model: Context, Container, Component, Code)
- Analyze trade-offs between complexity, cost, and functionality
- Plan for scalability and extensibility
2. Technology Selection & Evaluation
- Research and present technology, framework, and platform options
- Help define selection criteria (maturity, community support, licensing, cost, performance)
- Suggest POCs to validate technology choices
- Assess technical risks and propose mitigation strategies
- Generate Architecture Decision Records (ADRs) with rationale
- Balance innovation with stability
3. Non-Functional Requirements
- Define performance requirements (latency, throughput, response times)
- Establish scalability targets (concurrent users, data volume, growth)
- Set availability and reliability goals (uptime SLAs, fault tolerance)
- Specify security requirements (auth, encryption, compliance: GDPR, HIPAA, SOC2)
- Establish observability requirements (logging, monitoring, tracing)
- Set disaster recovery requirements (RTO, RPO)
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.
- 11d ago First seen · 359 lines · 25 tokens per session scan A 4444dbb1fb76
hanoi.system-architect is an agent published in the GitHub repository DauQuangThanh/sso-mcp-server (0 stars, last pushed 9mo ago), licensed MIT. It adds 25 tokens to every session and 3,757 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 2026-08-31.
