What is architecture-patterns?

A set of rules for organizing software into clear layers and boundaries, such as separating web routes, business services, and data access. It also covers clean architecture, project folders, dependency injection, and test standards.

Use it when designing backend systems, choosing folder and layer boundaries, enforcing import direction, defining test conventions, or reviewing whether an architecture is too complex.

It reduces tangled dependencies, inconsistent project structures, and code that is difficult to test or change. The right-sizing guidance helps avoid adding architecture that a project does not need.

SkillSpector: 1 finding, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

Hidden instructions were detected in comments or invisible text. These could contain malicious directives. Manual review is recommended.

Fix: Audit all comments and invisible characters. Remove any instructions that direct the agent to perform unauthorized actions. Use plain, reviewable content.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00056	$0.03049
Opus 5.5	$0.00022	$0.01220
Sonnet 5.5	$0.00011	$0.00610
Haiku 4.5	$0.00006	$0.00305

Security

Grade A, and why

architecture-patterns 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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/domain-entity-template.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Architecture Patterns

Consolidated architecture validation and enforcement patterns covering clean architecture, backend layer separation, project structure conventions, and test standards. Each category has individual rule files in rules/ loaded on-demand. House scars and dated decisions rescued from retired reference tutorials live in references/ork-delta.md; the tutorials themselves are upstream's job (see "Upstream coverage" below).

Quick Reference

Category	Rules	Impact	When to Use
Clean Architecture	3	HIGH	SOLID principles, hexagonal architecture, ports & adapters, DDD
Project Structure	2	HIGH	Folder conventions, nesting depth, import direction, barrel files
Backend Layers	3	HIGH	Router/service/repository separation, DI, file naming
Test Standards	3	MEDIUM	AAA pattern, naming conventions, coverage thresholds
Right-Sizing	2	HIGH	Architecture tier selection, over-engineering prevention, context-aware enforcement

Total: 13 rules across 5 categories

Quick Start

# Clean Architecture: Dependency Inversion via Protocol
class IUserRepository(Protocol):
    async def get_by_id(self, id: str) -> User | None: ...

class UserService:
    def __init__(self, repo: IUserRepository):
        self._repo = repo  # Depends on abstraction, not concretion

# FastAPI DI chain: DB -> Repository -> Service
def get_user_service(db: AsyncSession = Depends(get_db)) -> UserService:
    return UserService(PostgresUserRepository(db))

# Project Structure: Unidirectional Import Architecture
shared/lib  ->  components  ->  features  ->  app
(lowest)                                    (highest)

# Backend Layers: Strict Separation
Routers (HTTP) -> Services (Business Logic) -> Repositories (Data Access)

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.

architecture-patterns is a skill published in the GitHub repository yonatangross/orchestkit (296 stars, last pushed today), licensed MIT. It adds 56 tokens to every session and 3,049 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-09-03.
