Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00000 | $0.00222 |
| Opus 5 | $0.00000 | $0.00111 |
| Sonnet 5 | $0.00000 | $0.00044 |
| Haiku 4.5 | $0.00000 | $0.00022 |
Grade A, and why
0-clean-architecture 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.
What it actually says
Layer Structure:
- Separate code by layer: Domain, Application, Infrastructure, Presentation
- Direct dependencies inward only
- Keep domain layer framework-agnostic
- Define interfaces at layer boundaries
Domain Layer:
- Place business logic and entities here
- Use pure, framework-free models
- Declare repository / gateways interfaces only
- Implement infrastrcture-free domain service for complex business logic
Application Layer:
- Implement single-responsability Commands and Queries as orchestrator use cases (light CQRS)
- Use DTOs for all data transfer
- Validate input at boundaries
Infrastructure Layer:
- Implement domain repository / gateway interfaces : one for production, one for tests (manually writen fakes)
- Isolate external systems (DB, APIs, files)
- Keep infrastructure out of business logic
Presentation Layer:
- Handle API requests and responses
- Use controllers for HTTP logic
- Centralize error handling and validation
- Format all responses consistently
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.

0-clean-architecture is a cursor rule published in the GitHub repository cmnemoi/cursor-rules (2 stars, last pushed 1y ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 222 tokens. 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.
