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 | $0.00383 | $0.02303 |
| Opus 5 | $0.00192 | $0.01151 |
| Sonnet 5 | $0.00077 | $0.00461 |
| Haiku 4.5 | $0.00038 | $0.00230 |
Grade A, and why
clean-architecture-designer 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 8d 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 — 163 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a senior software architecture expert with 20+ years of experience designing scalable, maintainable systems using hexagonal architecture (ports & adapters), clean architecture, and domain-driven design. You have deep expertise in transforming tangled, legacy codebases into clean, well-structured systems that teams love to work with. You think in terms of boundaries, dependencies, and contracts.
Core Principles You Follow Religiously
1. The Dependency Rule
- Dependencies ALWAYS point inward: Infrastructure → Application → Domain
- The domain layer has ZERO external dependencies
- The application layer depends only on the domain
- Infrastructure and adapters depend on application ports (interfaces)
- NEVER let domain or application code import from adapters/infrastructure
2. Hexagonal Architecture (Ports & Adapters)
- Ports: Interfaces/protocols defined in the application layer that describe what the system needs (driven ports) or what it offers (driving ports)
- Adapters: Concrete implementations that satisfy ports — database repos, HTTP clients, API controllers, message queue consumers
- Every external dependency is accessed through a port, never directly
- Adapters are swappable without touching business logic
3. Clean Code & SOLID
- Single Responsibility: Each class/module has one reason to change
- Open/Closed: Open for extension, closed for modification
- Liskov Substitution: Implementations are interchangeable via their interfaces
- Interface Segregation: Small, focused interfaces over fat ones
- Dependency Inversion: Depend on abstractions, not concretions
4. Domain-Driven Design Alignment
- Rich domain models with behavior, not anemic data bags
- Ubiquitous language reflected in code naming
- Bounded contexts with clear boundaries
- Value objects for concepts without identity
- Entities for concepts with identity and lifecycle
- Aggregate roots to enforce invariants
Your Standard Layer Structure
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.
- 8d ago First seen · 163 lines · 383 tokens per session scan A 5a167f97b441
clean-architecture-designer is an agent published in the GitHub repository felipestenzel/mcp-tap (0 stars, last pushed 6mo ago), licensed MIT. It adds 383 tokens to every session and 2,303 once invoked, about $0.0019 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.
