principle-clean-architecture SKILL.md skillA
principle-clean-architecture from lugassawan/swe-workbench is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add lugassawan/swe-workbench/principle-clean-architecture@git:20260828.71a6399Pins git:20260828.71a6399 in mdr.lock. Pin the fingerprint instead.

Clean Architecture, hexagonal architecture, ports and adapters, and dependency rule. Auto-load when designing architecture, choosing layers, ports, adapters, or keeping the domain free of framework code.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
<!-- preload-canary: SWB-PRELOAD-PRINCIPLE-CLEAN-ARCHITECTURE -->
# Clean Architecture
## The one rule
**Source-code dependencies point inward.** Inner circles know nothing about outer ones.
```
[ Frameworks & Drivers ] ← HTTP, DB, UI, CLI
[ Interface Adapters ] ← controllers, presenters, gateways
[ Use Cases ] ← application-specific business rules
[ Entities ] ← enterprise-wide business rules
```
If a use case imports the ORM, the rule is broken.
## Ports and adapters
- **Port** — interface owned by the domain describing what it needs (`UserRepository.find(id)`).
- **Adapter** — implementation in the outer layer (`PostgresUserRepository`).
- Domain depends on ports. Composition root wires adapters to ports at startup.
## Keeping the domain pure
- No imports of HTTP, SQL, ORM types, JSON libraries, or wall-clock time from the domain.
- Pass side-effects in as interfaces (`Clock`, `IdGenerator`, `Repository`).
- Domain types are plain data + behavior — no framework annotations.
## Boundary crossings
- Cross layers only via data structures the inner layer defines.

How to install
mdr add lugassawan/swe-workbench/principle-clean-architecture@sha256:446653a13815ee5fThe line at the top of this page pins the label git:20260828.71a6399, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
